Scientists in Japan to put Stars-2 satellite into orbit to trial space cleanup | Scienc... - 0 views

  •  
    Japanese scientists are preparing to launch a satellite that will use a 300-meter electromagnetic tether to snag orbiting trash left over from past satellites and space missions. The magnetic field will slow the trash, causing it to gradually fall closer to Earth and eventually burn up in the atmosphere. It's thought there are tens of millions of trash fragments in orbit around the Earth.

Scientists have declared a biodiversity crisis - here's what that means for business | ... - 0 views

  •  
    The hollowing out of the natural world is being driven primarily by human activity, according to the scientists, with a growing global population leading to rising demand for food, goods and natural resources - leaving less land and sea as the preserve of the natural world. The paper also warns that this collapse in global biodiversity will in turn have "grave impacts" on human populations.

Climate Panel Cites Near Certainty on Warming - NYTimes.com - 0 views

  • An international panel of scientists has found with near certainty that human activity is the cause of most of the temperature increases of recent decades, and warns that sea levels could conceivably rise by more than three feet by the end of the century if emissions continue at a runaway pace.
  • “It is extremely likely that human influence on climate caused more than half of the observed increase in global average surface temperature from 1951 to 2010,” the draft report says. “There is high confidence that this has warmed the ocean, melted snow and ice, raised global mean sea level and changed some climate extremes in the second half of the 20th century.”
  • The draft comes from the Intergovernmental Panel on Climate Change, a body of several hundred scientists that won the Nobel Peace Prize in 2007, along with Al Gore. Its summaries, published every five or six years, are considered the definitive assessment of the risks of climate change, and they influence the actions of governments around the world. Hundreds of billions of dollars are being spent on efforts to reduce greenhouse emissions, for instance, largely on the basis of the group’s findings.

  • The 2007 report found “unequivocal” evidence of warming, but hedged a little on responsibility, saying the chances were at least 90 percent that human activities were the cause. The language in the new draft is stronger, saying the odds are at least 95 percent that humans are the principal cause.
  • On sea level, which is one of the biggest single worries about climate change, the new report goes well beyond the assessment published in 2007, which largely sidestepped the question of how much the ocean could rise this century.
  • Regarding the question of how much the planet could warm if carbon dioxide levels in the atmosphere doubled, the previous report largely ruled out any number below 3.6 degrees Fahrenheit. The new draft says the rise could be as low as 2.7 degrees, essentially restoring a scientific consensus that prevailed from 1979 to 2007.
  • But the draft says only that the low number is possible, not that it is likely. Many climate scientists see only a remote chance that the warming will be that low, with the published evidence suggesting that an increase above 5 degrees Fahrenheit is more likely if carbon dioxide doubles.
  • The level of carbon dioxide, the main greenhouse gas, is up 41 percent since the Industrial Revolution, and if present trends continue it could double in a matter of decades.

Carbon dioxide levels reach global milestone - 1 views

  •  
    Worldwide levels of carbon dioxide - the gas scientists say is most responsible for global warming - reached a significant milestone for the month of March, the National Oceanic and Atmospheric Administration said Wednesday. The global monthly average for carbon dioxide hit 400.83 parts per million in March, the first time the average surpassed 400 ppm for an entire month since such measurements began in the late 1950s, NOAA said.
  •  
    Global carbon dioxide levels averaged 400.83 parts per million in March, marking the first time that atmospheric carbon has remained above the 400 ppm threshold for an entire month, according to the National Oceanic and Atmospheric Administration. "It's both disturbing and daunting," said NOAA chief greenhouse gas scientist Pieter Tans.

Scientists Looking to Agave, Other Succulents as Model for Engineering Drought-Resistan... - 0 views

  •  
    As a punishing drought continues to grip California and other areas, scientists are exploring hardy succulents as a pathway to genetically engineer plants to use less water. Agave and other succulents such as the prickly pear, pineapple and vanilla have evolved to perform a different kind of photosynthesis that enable their survival in semiarid environments. These species absorb most of their carbon dioxide at night rather than during the day, as most plants do, meaning less water evaporates off the leaves through transpiration.

Why Are California Farmers Irrigating Crops With Oil Wastewater? - 0 views

  •  
    Since 2014, oil companies reported that they used more than 20 million pounds and 2 million gallons of chemicals in their operations, including at least 16 chemicals the state of California classifies as carcinogens or reproductive toxicants under the state's Proposition 65 law. That recycled wastewater was then sold to irrigation districts largely in Kern County. The Central Valley Regional Water Quality Control Board has allowed the practice for at least four decades and only recently required the oil companies and water districts to disclose the details. EWG detailed its findings in a report released Wednesday, two days before a public meeting of an expert panel convened to study the practice's safety. Although scientists don't know whether using oil field wastewater to grow crops poses a health risk to people who eat the food, the water board has refused to halt the practice until the expert panel releases its findings.

CLIMATE: 'Cool' clothing breakthrough could slash building emissions -- Friday, Septemb... - 0 views

  •  
    Turn off your air conditioner and stay cool in your shirt instead. That's the idea behind a new plastic-wrap-like material that Stanford University scientists say could be made into "cool" clothing, the use of which could slash emissions and energy consumption in buildings. If woven into fabric, the wearable cloth could keep humans cool on the hottest of days, eliminating the need to adjust the thermostat or crank up a fan. That could make a dent on a major source of U.S. greenhouse gases, the researchers say.

    Communities on the frontlines of fossil fuel development are taking a stand against dangerous fossil fuel projects. Take a look at the big fight in the small town of Kalama, Washington. The Chinese government is planning to build the world's largest methanol refinery to convert fracked natural gas to liquid methanol for export to China to make plastics. From a greenhouse gas perspective, this fight is a big deal. The methanol refinery alone would use more natural gas than all industry in Washington combined. Flip it around: If we win this one battle and stop the methanol refinery, we stop the equivalent of doubling industrial natural gas usage in Washington State. While the gas industry tries to spin natural gas as clean, new science shows just the opposite. The bulk of natural gas is methane, a potent greenhouse gas. Methane leakage from gas wells and pipelines led scientists to conclude that fracked gas can be as bad coal for our climate. And it gets worse. Gas production in North America relies heavily on fracking, a process famous for polluting air and water, endangering the health of nearby residents.

New maps show how our consumption impacts wildlife thousands of miles away - 1 views

  •  
    Global trade has made it easier to buy things. But our consumption habits often fuel threats to biodiversity - such as deforestation, overhunting and overfishing - thousands of miles away. Now, scientists have mapped how major consuming countries drive threats to endangered species elsewhere. Such maps could be useful for finding the most efficient ways to protect critical areas important for biodiversity, the researchers suggest in a new study published in Nature Ecology & Evolution. For example, the maps show that commodities used in the United States and the European Union exert several threats on marine species in Southeast Asia, mainly due to overfishing, pollution and aquaculture. The U.S. also exerts pressure on hotspots off the Caribbean coast of Costa Rica and Nicaragua, and at the mouth of the Orinoco around Trinidad and Tobago. European Union's impacts extend to the islands around Madagascar: Réunion, Mauritius and the Seychelles. The maps also revealed some unexpected linkages. For instance, the impact of U.S. consumption in Brazil appears to be much greater in southern Brazil (in the Brazilian Highlands where agriculture and grazing are extensive) than inside the Amazon basin, which receives a larger chunk of the attention. The U.S. also has high biodiversity footprint in southern Spain and Portugal, due to their impacts on threatened fish and bird species. These countries are rarely perceived as threat hotspots.

    pilot project that sought to demonstrate that carbon dioxide emissions could be locked up by turning them into rock appears to be a success. Tests at the CarbFix project in Iceland indicate that most of the CO2 injected into basalt turned into carbonate minerals in less than two years, far shorter a time than the hundreds or thousands of years that scientists had once thought such a process would take.
