'It Is Climate Change': India's Heat Wave Now The 5th Deadliest In World History | Thin... - 0 views

  • searing and continuing heat wave in India has so far killed more than 2,300 people, making it the 5th deadliest in recorded world history.
  • As temperatures soared up to 113.7 degrees Fahrenheit and needed monsoon rains failed to materialize, the country’s minister of earth sciences did not mince words about what he says is causing the disaster.
  • “Let us not fool ourselves that there is no connection between the unusual number of deaths from the ongoing heat wave and the certainty of another failed monsoon,” Harsh Vardhan said, according to Reuters. “It’s not just an unusually hot summer, it is climate change.”

  • “Attribution of events to climate change is still emerging as a science, but recent and numerous studies continue to speak to heat waves having strong links to warming climate,”
  • India is getting hotter as humans continue to pump carbon dioxide into the atmosphere. With these increases in heat, the report — produced by 1,250 international experts and approved by every major government in the world — said with high confidence that the risk of heat-related mortality would rise due to climate change and population increases, along with greater risk of drought-related water and food shortages.
  • extreme heat events “have become as much as 10 times more likely due to the current cumulative effects of human-induced climate change.”
  • Mann said that as climate change threatens to worsen as more carbon is emitted into the atmosphere, heat events once considered extreme would become relatively common. He noted that India’s nearly unprecedented deadly heat wave is occurring at current global warming levels of just 1.5 degrees Fahrenheit — so heat waves occurring under the “business as usual” global warming scenario that sees average temperatures rise 7 to 9 degrees by the end of the century would be much, much worse
  • The impacts of climate change are widely expected to be more harmful in poor countries than in their fully developed counterparts.

Heat is a serious threat to dairy cows - we're finding innovative ways to keep them cool - 0 views

  • Severe overheating can threaten cows’ health and their ability to get pregnant and carry calves to term.
  • Dairy farmers use fans and sprayers to cool cows in their barns, but there is a substantial need for better options. Existing systems use a lot of energy and water, which is costly for farmers. And climate change is raising temperatures and stressing California’s water supplies.
  • Cows are particularly sensitive to hot weather: Their body temperature is 101.5 degrees Fahrenheit, three degrees higher than humans, and they create a large amount of heat as they break down feed in their stomachs and produce milk.
  • ...5 more annotations...
  • These are all considered signs of heat stress. Once it sets in, cows will produce less milk. They may have trouble getting and staying pregnant, and in severe cases may die.
  • These strategies help cows regulate their body temperature, but use large quantities of water and electricity. The average California dairy farm spends US$140,000 annually on utilities. Furthermore, these systems may be insufficient during extreme heat waves.
  • Our first cooling technology uses mats buried approximately 4 inches underneath the sand bedding where cows lie down. Water flows through the mats and absorbs heat from the cows through conduction.
  • The second technology uses targeted direct evaporative cooling, sometimes referred to as a “swamp cooler,” and fabric ducts to blow cool air on the cows in the areas where cows eat and rest.
  • During our first test phase, we tested all four treatments on 32 cows at UC Davis and collected data on their respiration rates, body temperature, milk yield and behavior, as well as weather, water use and energy use. Data analysis is underway. We anticipate that we will identify at least one option that will cool cows as effectively as current options, but will also save water, energy or both.

A blob of hot ocean water killed a million seabirds, scientists say - CNN - 0 views

  • As many as one million seabirds died at sea in less than 12 months in one of the largest mass die-offs in recorded history -- and researchers say warm ocean waters are to blame.
  • The birds, a fish-eating species called the common murre, were severely emaciated and appeared to have died of starvation between the summer of 2015 and the spring of 2016, washing up along North America's west coast, from California to Alaska.
  • The heat wave created the Blob -- a 1,000-mile (1,600 km) stretch of ocean that was warmed by 3 to 6 degrees Celsius (5.4 to 10.8 Fahrenheit). A high-pressure ridge calmed the ocean waters -- meaning heat stays in the water, without storms to help cool it down.
  • ...4 more annotations...
  • Other animals that experienced mass die-offs include sea lions, tufted puffins, and baleen whales. But none of them compared to the murres in scale.
  • The murres likely starved to death because the Blob caused more competition for fewer small prey. The warming increased the metabolism of predatory fish like salmon, cod, and halibut -- meaning they were eating more than usual. These fish eat the same small fish as the murres, and there simply wasn't enough to go around.
  • During the 2015 breeding season, three colonies didn't produce a single chick. That number went up to 12 colonies in the 2016 season -- and in reality it could be even higher, since researchers only monitor a quarter of all colonies.
  • It's especially rare to see a patch of warm ocean water over such a large area, but scientists say global climate change is making these phenomena more common. From 1982 to 2016, there was an 82% rise in the number of heat wave days on the global ocean surface, according to a 2018 study. That's because heat waves are increasing in both frequency and duration, with the highest level of maritime heat wave activity occurring in the North Atlantic

Clouds' Effect on Climate Change Is Last Bastion for Dissenters - NYTimes.com - 0 views

But the worst possible place to resolve such issues is the political arena." Alexander Flax, Potomac, MD Read Full Comment » Post a Comment » Over time, nearly every one of their arguments has been knocked down by accumulating evidence, and polls say 97 percent of working climate scientists now see global warming as a serious risk.
  • They acknowledge that the human release of greenhouse gases will cause the planet to warm. But they assert that clouds — which can either warm or cool the earth, depending on the type and location — will shift in such a way as to counter much of the expected temperature rise and preserve the equable climate on which civilization depends.
  • At gatherings of climate change skeptics on both sides of the Atlantic, Dr. Lindzen has been treated as a star. During a debate in Australia over carbon taxes, his work was cited repeatedly. When he appears at conferences of the Heartland Institute, the primary American organization pushing climate change skepticism, he is greeted by thunderous applause.
  • ...13 more annotations...
  • His idea has drawn withering criticism from other scientists, who cite errors in his papers and say proof is lacking. Enough evidence is already in hand, they say, to rule out the powerful cooling effect from clouds that would be needed to offset the increase of greenhouse gases.
  • “If you listen to the credible climate skeptics, they’ve really pushed all their chips onto clouds.”
  • Dr. Lindzen is “feeding upon an audience that wants to hear a certain message, and wants to hear it put forth by people with enough scientific reputation that it can be sustained for a while, even if it’s wrong science,” said Christopher S. Bretherton, an atmospheric researcher at the University of Washington. “I don’t think it’s intellectually honest at all.”
  • With climate policy nearly paralyzed in the United States, many other governments have also declined to take action, and worldwide emissions of greenhouse gases are soaring.
  • The most elaborate computer programs have agreed on a broad conclusion: clouds are not likely to change enough to offset the bulk of the human-caused warming. Some of the analyses predict that clouds could actually amplify the warming trend sharply through several mechanisms, including a reduction of some of the low clouds that reflect a lot of sunlight back to space. Other computer analyses foresee a largely neutral effect. The result is a big spread in forecasts of future temperature, one that scientists have not been able to narrow much in 30 years of effort.
  • The earth’s surface has already warmed about 1.4 degrees Fahrenheit since the Industrial Revolution, most of that in the last 40 years. Modest as it sounds, it is an average for the whole planet, representing an enormous addition of heat. An even larger amount is being absorbed by the oceans. The increase has caused some of the world’s land ice to melt and the oceans to rise.
  • Even in the low projection, many scientists say, the damage could be substantial. In the high projection, some polar regions could heat up by 20 or 25 degrees Fahrenheit — more than enough, over centuries or longer, to melt the Greenland ice sheet, raising sea level by a catastrophic 20 feet or more. Vast changes in  rainfall, heat waves and other weather patterns would most likely accompany such a large warming. “The big damages come if the climate sensitivity to greenhouse gases turns out to be high,” said Raymond T. Pierrehumbert, a climate scientist at the University of Chicago. “Then it’s not a bullet headed at us, but a thermonuclear warhead.”
  • But the problem of how clouds will behave in a future climate is not yet solved — making the unheralded field of cloud research one of the most important pursuits of modern science.
  • for more than a decade, Dr. Lindzen has said that when surface temperature increases, the columns of moist air rising in the tropics will rain out more of their moisture, leaving less available to be thrown off as ice, which forms the thin, high clouds known as cirrus. Just like greenhouse gases, these cirrus clouds act to reduce the cooling of the earth, and a decrease of them would counteract the increase of greenhouse gases. Dr. Lindzen calls his mechanism the iris effect, after the iris of the eye, which opens at night to let in more light. In this case, the earth’s “iris” of high clouds would be opening to let more heat escape.
  • Dr. Lindzen acknowledged that the 2009 paper contained “some stupid mistakes” in his handling of the satellite data. “It was just embarrassing,” he said in an interview. “The technical details of satellite measurements are really sort of grotesque.” Last year, he tried offering more evidence for his case, but after reviewers for a prestigious American journal criticized the paper, Dr. Lindzen published it in a little-known Korean journal. Dr. Lindzen blames groupthink among climate scientists for his publication difficulties, saying the majority is determined to suppress any dissenting views. They, in turn, contend that he routinely misrepresents the work of other researchers.
  • Ultimately, as the climate continues warming and more data accumulate, it will become obvious how clouds are reacting. But that could take decades, scientists say, and if the answer turns out to be that catastrophe looms, it would most likely be too late. By then, they say, the atmosphere would contain so much carbon dioxide as to make a substantial warming inevitable, and the gas would not return to a normal level for thousands of years.
  • In his Congressional appearances, speeches and popular writings, Dr. Lindzen offers little hint of how thin the published science supporting his position is. Instead, starting from his disputed iris mechanism, he makes what many of his colleagues see as an unwarranted leap of logic, professing near-certainty that climate change is not a problem society needs to worry about.
  • “Even if there were no political implications, it just seems deeply unprofessional and irresponsible to look at this and say, ‘We’re sure it’s not a problem,’ ” said Kerry A. Emanuel, another M.I.T. scientist. “It’s a special kind of risk, because it’s a risk to the collective civilization.”

Are We Being Framed? | JSTOR Daily - 0 views

  • So the Mueller Report is finally out. President Trump has called it a “total exoneration,” but we don’t have to take his word for it. After special counsel Robert Mueller’s comprehensive, two-year investigation into serious allegations of Russian electoral interference, conspiracy, and obstruction of justice, we’re free to read what the special counsel’s findings actually are, if we so choose—albeit with a number of careful redactions from William Barr that along with his four-page summary, framed public conversations about the report in important ways.
  • It can persuade us one way or another by using certain rhetorical or linguistic means. What’s more, a particular framing doesn’t just arise spontaneously to the top of the public consciousness from its own legitimate merits, because it happens to be the neutral truth. We would be naive to think so, yet many people do. When it comes to the power of states, in sociologist Christopher A. Bail’s view, it has to be knowingly crafted, with two realities. One is a front stage presentation for public consumption and the other a secret collective coordination behind the scenes. Their reality becomes your reality, one way or another.
  • To Dwight Bolinger, “literal truth—the kind one swears to tell on the witness stand—permits any amount of evasion.” He explains: “The most insidious of all concepts of truth is that of literalness. The California prune-growers tell us that prunes, pound for pound, offer several times more vitamins and minerals than fresh fruit; literally true. The oil industry advertises that no heat costs less than oil heat, which has to be true because no heat costs nothing at all.” Those savvy enough to see through it will simply eat fewer prunes and heat their homes differently to those who fall for it. But declaring that you didn’t lie but told the literal truth in this way seems a kind of hollow ethic, a careful weaselling around the words that some lawyers seem particularly adept at.
  • ...4 more annotations...
  • So, yes, it’s perhaps literally true that no collusion was found by Mueller’s team because they weren’t actually investigating collusion, but a much harder-to-prove charge of criminal conspiracy. Collusion and conspiracy may be related, but they’re not the same. Yet in the resulting media commentary, this framing by the Trump administration was largely successful in amplifying the confused conflation of two separate concepts: One is the fact that Mueller did not ultimately find definitive proof that the Trump campaign illegally conspired with Russia; The other is the non-legal Trump talking point of “no collusion,” even though not finding something is certainly not the same as there being none (at least you would hope so, if you ever can’t find your house keys or wallet).
  • One such case is Muscarello v. United States, from 1998. The law was that anyone caught using or carrying a firearm while selling drugs (presumably on their person) would get an additional five year sentence. The defendant, Muscarello, had a firearm that he was actively not carrying because it was actually locked up in the glove compartment of his truck. Nevertheless this was redefined as “carrying” a firearm, because the judge in the case saw that one of the first definitions in a dictionary for the word happen to be in relation to “carrying” (i.e. transporting) things in vehicles.
  • These are all fairly simple and obvious features of dictionaries that are frequently overlooked in legal contexts, just when it matters most that careful and ethical consideration should go into the linguistic interpretation of the law.
  • If we don’t pay enough attention to linguistic ethics, language and the truth that it seems to tell can be subtly manipulated to misdirect us. Even the most precise legal wording of a thorough report can be misread, as long as the public is willing to allow it.

Upon closer look, a global warming hiatus is ruled out, U.S. scientists say - LA Times - 0 views

  • fresh look at the way sea temperatures are measured has led government scientists to make a surprising claim: The puzzling apparent hiatus in global surface warming never really happened
  • Mainstream scientists have struggled to explain to the public how climate change can be getting worse if the warming of the planet's surface slowed at the turn of the century. Their various theories have chalked it up to dust and ash blasted into the sky by volcanic eruptions, a rare period of calm in the solar cycle, and heat absorption by the Pacific Ocean and other waters.
  • “I don't find this analysis at all convincing,” said Judith Curry, a climatologist at Georgia Tech who argues that natural variability in climate cycles dominates the impact of industrial emissions and other human actions. “While I'm sure this latest analysis from NOAA will be regarded as politically useful for the Obama administration, I don't regard it as a particularly useful contribution to our scientific understanding of what is going on.”
  • ...7 more annotations...
  • In the study, the NOAA researchers argue that long-standing problems with the way temperatures are measured have masked years of sea surface warming. Once those problems are corrected for, “this hiatus or slowdown simply vanishes,” said lead study author Thomas Karl, director of NOAA's National Climatic Data Center in Asheville, N.C.
  • Although researchers have long known that sea surface temperatures measured by autonomous buoys run cooler than temperatures measured by ships, they have failed to account for this as they expanded their use of buoy readings over the last two decades, the study authors argued.
  • “The buckets, when you pull them up, tend to evaporate their water, and if they're canvas there's even more evaporation,” Karl said. “By the time people stick a thermistor in the bucket to measure temperature, it's already slightly cool.”
  • “If you start a short-time series on an anomalous value, you tend to get an anomalous trend,” Karl said.
  • A growing number of climate scientists have argued that this phenomenon, as well as other hiatus effects, are evidence of a poorly understood pattern of wind, ocean current and temperature variations that have far-reaching effects on global climate. They say the oceans have absorbed heat energy from the sun, causing Arctic ice to melt and sea levels to rise.
  • “One way to think about it is that global warming continued, but the oceans just juggled a bit of heat around and made the surface seem cooler for a while,” said Joshua Willis, another climate scientist at JPL.
  • “All of those factors are real,” Karl said. “If those factors had not occurred, the warming rate would have been even greater. … If anything we may still be underestimating the trend.”

Oceans are warming at the same rate as if five Hiroshima bombs were dropped in every se... - 0 views

shared by tongoscar on 20 Jan 20 - No Cached
  • An international team of 14 scientists examined data going back to the 1950s, looking at temperatures from the ocean surface to 2,000 meters deep.
  • The study shows that while the oceans warmed steadily between 1955 and 1986, warming has accelerated rapidly in the last few decades. Between 1987-2019, ocean warming was 450% greater than during the earlier time period.
  • That's equivalent to dropping roughly four Hiroshima bombs into the oceans every second over the past quarter of a century. But because the warming is speeding up, the rate at which we are dropping these imaginary bombs is getting faster than ever.
  • ...2 more annotations...
  • Oceans serve as a good indicator of the real impact of climate change. Covering almost three quarters of Earth's surface, they absorb the vast majority of the world's heat. Since 1970, more than 90% of the planet's excess heat went into the oceans, while less than 4% was absorbed by the atmosphere and the land, the study said.
  • But just because people live on land doesn't mean they are immune from the effects of the warming waters. Ocean warming has a profound impact on the entire world.

A Hair-Raising Hypothesis About Rodent Hair - The New York Times - 0 views

  • Observations of predator behavior further piqued his interest. While filming and playing back his videos, he noted how cats stack their bodies behind their faces when they’re hunting. He interprets this, he said, as cats “trying to hide their heat” with their cold noses. He has also observed barn owls twisting as they swoop down, perhaps to shield their warmer parts — legs and wingpits — with cooler ones.
  • Maybe, he thought, “predators have to conceal their infrared to be able to catch a mouse.”
  • Eventually, these and other musings led Dr. Baker to place mouse hairs under a microscope. As it came into view, he felt a strong sense of familiarity. The guard hair in particular — the bristliest type of mouse hair — contained evenly-spaced bands of pigment that, to Dr. Baker, closely resembled structures that allow optical sensors to tune into specific wavelengths of light.
  • Thermal cameras, for instance, focus specifically on 10-micron radiation: the slice of the spectrum that most closely corresponds with heat released by living things. By measuring the stripes, Dr. Baker found they were tuned to 10 microns as well — apparently homed in on life’s most common heat signature. “That was my Eureka moment,” he said.

Global Warming 'Hiatus' Challenged by NOAA Research - NYTimes.com - 0 views

  • Scientists have long labored to explain what appeared to be a slowdown in global warming that began at the start of this century as, at the same time, heat-trapping emissions of carbon dioxide were soaring. The slowdown, sometimes inaccurately described as a halt or hiatus, became a major talking point for people critical of climate science.
  • When adjustments are made to compensate for recently discovered problems in the way global temperatures were measured, the slowdown largely disappears, the National Oceanic and Atmospheric Administration declared in a scientific paper published Thursday. And when the particularly warm temperatures of 2013 and 2014 are averaged in, the slowdown goes away entirely, the agency said.
  • “The notion that there was a slowdown in global warming, or a hiatus, was based on the best information we had available at the time,” said Thomas R. Karl, director of the National Centers for Environmental Information, a NOAA unit in Asheville, N.C. “Science is always working to improve.”
  • ...7 more annotations...
  • senior climate scientists at other agencies were in no hurry to embrace NOAA’s specific adjustments. Several of them said it would take months of discussion in the scientific community to understand the data corrections and come to a consensus about whether to adopt them broadly.
  • NOAA said the improvements in its data set included the addition of a huge number of land measurements from around the world, as a result of improving international cooperation in sharing weather records. But the disappearance of the slowdown comes largely from adjustments in ocean temperatures.
  • NOAA is one of four agencies around the world that attempts to produce a complete record of global temperatures dating to 1880. They all get similar results, showing a long-term warming of the planet that scientists have linked primarily to the burning of fossil fuels and the destruction of forests. A huge body of physical evidence — notably, that practically every large piece of land ice on the planet has started to melt — suggests the temperature finding is correct.
  • Yet the temperature record is plagued by many problems: thermometers and recording practices changed through time, weather stations were moved, cities grew up around once-rural stations, and so on. Entire scientific careers are devoted to studying these issues and making corrections.
  • A leading hypothesis to explain the slowdown is that natural fluctuations in the Pacific Ocean may have temporarily pulled some heat out of the atmosphere, producing a brief flattening in the long-term increase of surface temperatures.
  • ocean measurements in particular are rife with difficulties.
  • Even if the warming slowdown in the early 21st century was real, there seems to be little question that it is ending. By a small margin, the global temperature hit a record in 2014, and developing weather patterns suggest that record will likely be broken by a larger margin in 2015.

How Warm Temperatures Affect Us - WSJ.com - 0 views

  • Could a few feet of the cold stuff really have such a fundamental effect on beliefs and behavior? Absolutely, according to recent studies on how temperature influences us at an unconscious level. Researchers affiliated with the Center for Decision Sciences at Columbia Business School measured the public's changing attitudes about climate change
  • Those who felt that the current day was warmer than usual for the time of year were more likely to believe in and worry about global warming than those who thought it was cooler outside. They were also more likely to donate the money they earned from taking the survey to a charity that did work on climate change.

  • Physical warmth activates circuits in the brain associated with feelings of psychological warmth. The insular cortex, or insula, plays a critical role in this crossover between the outside world and our experience of it. This peach-sized region helps us to perceive whether a sensation is hot or cold, pleasurable or painful. It is activated when we crave chocolate, fall in love or get disgusted. The insula also guides us on social matters: whether to trust or feel guilty, to empathize or be embarrassed. People who meditate, according to some studies, have a thicker insula.
  • As it turns out, the insula's poetic merging of the physical and emotional helps to explain much of our unconscious behavior. People who are socially rejected—given the cold shoulder—get chills and crave warm food such as soup.
  • Warm springtime conditions are related to a better mood and expanded memory, but both take a plunge in the summer heat. Extreme temperatures make people hostile and aggressive, and violent crimes occur more often in the hotter months. Drivers honk more in heat waves. When you're hot and tired, you're more likely to interpret another person's neutral expression negatively.
  • our perception of reality still relies on sensory experience. Though we may wish for it to be otherwise, our minds cannot be separated from our bodies. And our bodies depend on the environment—what we encounter here on planet Earth

Why Study Philosophy? 'To Challenge Your Own Point of View' - The Atlantic - 1 views

  • Goldstein’s forthcoming book, Plato at the Googleplex: Why Philosophy Won’t Go Away, offers insight into the significant—and often invisible—progress that philosophy has made. I spoke with Goldstein about her take on the science vs. philosophy debates, how we can measure philosophy’s advances, and why an understanding of philosophy is critical to our lives today.
  • One of the things about philosophy is that you don’t have to give up on any other field. Whatever field there is, there’s a corresponding field of philosophy. Philosophy of language, philosophy of politics, philosophy of math. All the things I wanted to know about I could still study within a philosophical framework.
  • There’s a peer pressure that sets in at a certain age. They so much want to be like everybody else. But what I’ve found is that if you instill this joy of thinking, the sheer intellectual fun, it will survive even the adolescent years and come back in fighting form. It’s empowering.

Because I was seen as a hard-core analytic philosopher, and when I first began to write novels people thought, Oh, and we thought she was serious! But that’s changed entirely. People take literature seriously, especially in moral philosophy, as thought experiments. A lot of the most developed and effective thought experiments come from novels. Also, novels contribute to making moral progress, changing people’s emotions.
  • The other thing that’s changed is that there’s more applied philosophy. Let’s apply philosophical theory to real-life problems, like medical ethics, environmental ethics, gender issues. This is a real change from when I was in school and it was only theory.

  • Plato would be constantly surprised by what we know. And not only what we know scientifically, or by our technology, but what we know ethically. We take a lot for granted. It’s obvious to us, for example, that individual’s ethical truths are equally important.
  • it’s usually philosophical arguments that first introduce the very outlandish idea that we need to extend rights. And it takes more, it takes a movement, and activism, and emotions, to affect real social change. It starts with an argument, but then it becomes obvious.

  • About 30 years ago, the philosopher Peter Singer started to argue about the way animals are treated in our factory farms. Everybody thought he was nuts. But I’ve watched this movement grow; I’ve watched it become emotional. It has to become emotional. You have to draw empathy into it. But here it is, right in our time—a philosopher making the argument, everyone dismissing it, but then people start discussing it. Even criticizing it, or saying it’s not valid, is taking it seriously
  • This is what we have to teach our children. Even things that go against their intuition they need to take seriously. What was intuition two generations ago is no longer intuition; and it’s arguments that change i
  • We are very inertial creatures. We do not like to change our thinking, especially if it’s inconvenient for us. And certainly the people in power never want to wonder whether they should hold power.
  • I’m really trying to draw the students out, make them think for themselves. The more they challenge me, the more successful I feel as a teacher. It has to be very active
  • Plato used the metaphor that in teaching philosophy, there needs to be a fire in the teacher, and the sheer heat will help the fire grow in the student. It’s something that’s kindled because of the proximity to the heat.
  • how can you make the case that they should study philosophy?
  • ches your inner life. You have lots of frameworks to apply to problems, and so many ways to interpret things. It makes life so much more interesting. It’s us at our most human. And it helps us increase our humanity. No matter what you do, that’s an asset.
  • What do you think are the biggest philosophical issues of our time? The growth in scientific knowledge presents new philosophical issues.
  • The idea of the multiverse. Where are we in the universe? Physics is blowing our minds about this.
  • The question of whether some of these scientific theories are really even scientific. Can we get predictions out of them?
  • And with the growth in cognitive science and neuroscience. We’re going into the brain and getting these images of the brain. Are we discovering what we really are? Are we solving the problem of free will? Are we learning that there isn’t any free will? How much do the advances in neuroscience tell us about the deep philosophical issues?
  • With the decline of religion is there a sense of the meaninglessness of life and the easy consumerist answer that’s filling the space religion used to occupy? This is something that philosophers ought to be addressing.

Most Americans believe politicians' heated rhetoric can lead to violence, report finds ... - 0 views

  • A report published by the Pew Research Center on Wednesday found that 78% of Americans believed such rhetoric from elected officials makes violence against targeted groups more likely. A similar majority, 73% of those surveyed, believed elected officials should avoid heated language because it encourages violence.
  • Among those surveyed, 55% said Trump had changed the tone and nature of political debate for the worse. Given a list of positive and negative sentiments, ranging from “hopeful” to “concerned”, a large majority said the president’s statements often or sometimes made them “concerned”, “confused” and “embarrassed”.
  • The most popular positive reaction, from 54% of those polled, was “entertained”.

  • Recent studies have nonetheless pointed to an increase in crimes against some groups following Trump’s White House run and election victory. After years of falling, hate crimes have risen in the last three years. One analysis from the Washington Post found that counties that hosted a Trump rally in 2016 saw a 226% increase in hate crimes. Student surveys from Virginia found higher rates of bullying and teasing in areas that voted for Trump.
  • Benesch coined the term “dangerous speech” – meaning rhetoric that is used to turn one group of people violently against another – after years of studying speech used to instigate atrocities like the Holocaust.
  • “He absolutely uses the language of threat,” Benesch said. “He describes non-citizens as ‘invaders’ and as an ‘invasion’ – that is highly characteristic language of dangerous speech.
  • “It will be only when people have enough courage and love of country to call out dangerous rhetoric on their own side that we will see norms shifting in the right direction,” Benesch said. “It’s a very difficult thing to do.”

Study shows how climate change will affect SE Michigan - News - Bedford Now - Bedford T... - 0 views

  • Climate change will continue to affect southeast Michigan, but there are ways to protect ourselves and those around us, according to a new University of Michigan study.
  • ‘I think that for many people, they think that climate change is far away or it’s happening in Australia but not here,’ Koman said. ‘It’s certainly happening here, so maps like this I hope can bring that picture home to people.’
  • ‘I think that the most important thing to think about is that we can make changes. The adverse consequences of heat stress are actionable; we can prevent these problems ...,’ she said.
  • ...2 more annotations...
  • Koman explained that there were numerous factors that indicate many residents of southeast Michigan are particularly vulnerable to the effects of climate change, including the area’s high poverty level and a shortage of affordable housing.
  • “It’s also the customs we have, reducing social isolation and just checking on senior neighbors ... All those sorts of things we can do to prevent the worst outcomes of heat stress vulnerability, but we have to know who is at risk, we have to know where those problems are to do something about them.”

Climate Change Obsession Is a Real Mental Disorder - WSJ - 0 views

  • If heat waves were as deadly as the press proclaims, Homo sapiens couldn’t have survived thousands of years without air conditioning. Yet here we are
  • Humans have shown remarkable resilience and adaptation—at least until modern times, when half of society lost its cool over climate change.
  • it’s alarmist stories about bad weather that are fueling mental derangements worthy of the DSM-5—not the warm summer air itself.

  • The Bloomberg article cites a July meta-analysis in the medical journal Lancet, which found a tenuous link between higher temperatures and suicides and mental illness. But the study deems the collective evidence of “low certainty” owing to inconsistent study findings, methodologies, measured variables and definitions.
  • “climate change might not necessarily increase mental health issues because people might adapt over time, meaning that higher temperatures could become normal and not be experienced as anomalous or extreme.”
  • yes. Before the media began reporting on putative temperature records—the scientific evidence for which is also weak—heat waves were treated as a normal part of summer. Uncomfortable, but figuratively nothing to sweat about.
  • according to a World Health Organization report last year, the very “awareness of climate change and extreme weather events and their impacts” may lead to a host of ills, including strained social relationships, anxiety, depression, intimate-partner violence, helplessness, suicidal behavior and alcohol and substance abuse.
  • A study in 2021 of 16- to 25-year-olds in 10 countries including the U.S. reported that 59% were very or extremely worried about climate change, and 84% were at least moderately worried
  • Forty-five percent claimed they were so worried that they struggled to function on a daily basis, the definition of an anxiety disorder.
  • “First and foremost, it is imperative that adults understand that youth climate anxiety (also referred to as eco-anxiety, solastalgia, eco-guilt or ecological grief) is an emotionally and cognitively functional response to real existential threats,” a May 10 editorial in the journal Nature explained. “Although feelings of powerlessness, grief and fear can be profoundly disruptive—particularly for young people unaccustomed to the depth and complexity of such feelings—it is important to acknowledge that this response is a rational one.”
  • These anxieties are no more rational than the threats from climate change are existential.
  • A more apt term for such fear is climate hypochondria.
  • The New Yorker magazine earlier this month published a 4,400-word piece titled “What to Do With Climate Emotions” by Jia Tolentino, a woman in the throes of such neurosis
  • Ms. Tolentino goes on to describe how climate therapists can help patients cope. “The goal is not to resolve the intrusive feeling and put it away” but, as one therapist advises her, “to aim for a middle ground of sustainable distress.” Even the climate left’s despair must be “sustainable.”
  • there’s nothing normal about climate anxiety, despite the left’s claims to the contrary.
  • Progressives may even use climate change to displace their other anxieties—for instance, about having children
  • Displacement is a maladaptive mechanism by which people redirect negative emotions from one thing to another
  • Climate hypochondriacs deserve to be treated with compassion, much like anyone who suffers from mental illness. They shouldn’t, however, expect everyone else to enable their neuroses.
