On July 20th, James Hansen, the former NASA climatologist who brought climate change to the public's attention in the summer of 1988, issued a bombshell: He and a team of climate scientists had identified a newly important feedback mechanism off the coast of Antarctica that suggests mean sea levels could rise 10 times faster than previously predicted: 10 feet by 2065. The authors included this chilling warning: If emissions aren't cut, "We conclude that multi-meter sea-level rise would become practically unavoidable. Social disruption and economic consequences of such large sea-level rise could be devastating. It is not difficult to imagine that conflicts arising from forced migrations and economic collapse might make the planet ungovernable, threatening the fabric of civilization."

New research suggests that millions of Americans currently live in regions that would be inundated by rising oceans if global temperatures continue to rise. The major remaining question isn't whether such change is coming, but rather how quickly it will come, says researcher Benjamin Strauss. "The question is, how long is the fuse and has it been lit yet?" he says. 

Americans are being exposed to significantly lower levels of some phthalates - chemicals often referred to as plasticizers - that were banned from children's products in 2008, but exposures to other forms of these chemicals are rising steeply, according to a study led by researchers at University of California, San Francisco.

For thousands of years, sea level has remained relatively stable and human communities have settled along the planet's coastlines. But now Earth's seas are rising. Globally, sea level has risen about eight inches (20 centimeters) since the beginning of the 20th century and more than two inches (5 centimeters) in the last 20 years alone. All signs suggest that this rise is accelerating.

Unregulated carbon pollution from aviation is the fastest-growing source of the greenhouse gas emissions driving global climate change. In fact, if the entire aviation sector were a country, it would be one of the top 10 carbon-polluting nations on the planet. The good news is that we now have a process in place to curb international aviation's skyrocketing emissions. For the first time ever, the United Nations' civil aviation body agreed last week to put a cap on the emissions for an international sector rather than a country. International aviation already accounts for over 2% of global carbon emissions. But this number will soar as demand for air travel continues to rises. In 2010, the aviation industry carried 2.4 billion passengers; in 2050, the number is forecast to rise to 16 billion.

A new peer-reviewed study shows that widespread use of algae in animal feed could help limit the rise in global temperature to 2°C by 2100 and possibly even turn back the clock, bringing atmospheric carbon concentrations down to pre-industrial levels by the end of the century. Algae-based feeds have proven to be equal to or better than other feedstocks in nutritional value and digestibility, and could free large swaths of arable land and simultaneously address food security issues in an era of rising demand for animal proteins.

The euphoria over rise in world tiger population early this year may have been misplaced for India as the official data placed before Parliament shows that 98 tigers died in the country by November 16, 2016, a steep 25 per cent rise over last year when 78 deaths were reported. There are many anti-poaching measures initiated by NTCA which coordinate with state forest departments, but to little avail. In fact, poaching cases increased by more than 100 per cent this year. The figures attribute nearly 30 tiger deaths to poaching this year, which is more than double of last year's figure of 14. Top forest officials that Mail Today spoke with expressed helplessness in their fight against poachers and at times cited "political pressures'' leading to more frequent man-tiger conflict.

A report in the journal Nature Climate Change said climate change and rising sea levels could threaten 13.1 million people living along the coastal United States. The study combines population projections with rising sea level models. The areas with the greatest percentage of people at risk are Florida's Miami-Dade and Broward counties. Smaller communities are threatened too and are dealing now with environmental changes.

Sales of organic produce have been steadily rising, and farmers worldwide have stepped up to provide a year-round supply of certified organic fruits and vegetables, experts say. Nearly all items in the produce section are available in organic, with prices fluctuating based on supply, says Claris Ritter of Alfalfa's Market in Colorado. "Price is really a function of supply, and we're still having greater demand than supply," Ritter said. "We'll have to see, if we ever do catch up to the demand, what happens with the price

Atmospheric carbon levels have reached 402 parts per million, the highest level in about 800,000 years, according to the National Oceanic and Atmospheric Association. "Humans have caused carbon dioxide concentrations to rise 120 ppm since preindustrial times, with over 90% of that in the past century alone," said James Butler, director of NOAA's Global Monitoring Division

Finally, the fashion industry realizes we cannot continue this trend in a world where the rising population will have to devote more land to food - or even energy. We cannot continue to grow cotton like mad, nor can we endlessly spin fossil fuels into polyester or other synthetic fabrics. The road toward more sustainable fibers will be a long one with plenty of failures and misses, but it is one we need to take. That is, at least, absent a total rethink of how many clothes we really need in our closets - a discussion the large global clothing chains want to avoid.

Venice is the Mediterranean World Heritage Site currently most at risk from flooding due to sea level rise, according to a recent study, and the city even has elevated sidewalks ready in case of high tides, but Monday's waters rose higher than the emergency sidewalks. The tide surpassed 5 feet, 3 inches, making it the highest recorded since 2008 and potentially the highest recorded since 1979, CNN reported.

The world's oceans are rising in temperature faster than previously believed as they absorb most of the world's growing climate-changing emissions, scientists said Thursday.

The story that should dominate every end of year round up from every media outlet on the planet came last month in the form of two reports released at the U.N. climate summit in Bonn. The first confirmed atmospheric concentrations of carbon dioxide are at their highest levels in at least 800,000 years and possibly 3 million to 5 million years. As Emily Shuckburgh of the British Antarctic Survey said, the last time concentrations of greenhouse gas were as high as they are, sea levels were around 10 meters higher. Up to two meters of sea level rise this century is now entirely plausible. However, the second report was the real kicker. The Global Carbon Project predicted carbon emissions will rise this year after four years when flat emissions fuelled hopes global economic growth and carbon emissions had been decoupled

Satellite readings show that atmospheric methane and carbon dioxide are continuing to increase despite global efforts to reduce emissions. Methane concentrations were somewhat constant until 2007, but since then have increased at about 0.3% per year, whereas global carbon dioxide levels continue to rise at about 0.5% per year. The world's atmospheric methane and carbon dioxide levels continue to climb despite endeavors to rein in global emissions, new research shows. Carbon levels have risen by 0.5% per year since 2007, and methane levels are rising at about 0.3% per year.

The sales of electric vehicles and other alternatively-powered cars are on the rise, according to several industry reports released this summer.

In 1900, an estimated 100,000 tigers roamed free on our planet. Yet within a hundred years, that number plummeted by more than 95 percent - the result of rampant poaching and widespread habitat loss. But it seems the tide may finally be turning for the majestic cat. On Sunday, the World Wildlife Fund (WWF) announced that wild tiger numbers were on the rise for the first time in over a century.

At the University of Miami's Department of Atmospheric Sciences, Brian McNoldy and other researchers have been accumulating sea level data from Virginia Key (a small island just south of Miami Beach) since 1996. Over those nineteen years, sea levels around the Miami coast have already gone up 3.7 inches.
