A new study finds that a 4% reduction in China's carbon emissions by 2030 could save a total of $464.5 billion in healthcare costs, writes Chase Purdy for Quartz. “We have all these policy goals for a transition toward a more sustainable society,” says Associate Prof. Noelle Selin. “Mitigating air pollution, a leading cause of death, is one of them, and avoiding dangerous climate change is another.”
Prof. Susan Solomon has been named one of two recipients of this year’s Crafoord Prize for her contributions to climate research, according to the Associated Press. Solomon was honored for her, "fundamental contributions to understanding the role of atmospheric trace gases in Earth's climate system."
A study by Prof. Daniel Rothman shows that there could be enough carbon in the Earth’s oceans by 2100 to trigger a sixth mass extinction, reports Mark Fischetti and Jen Christiansen for Scientific American.
In an article for The Wall Street Journal, Christopher Matthews highlights a new study by Prof. Kerry Emanuel that shows Texas faces an increased risk of devastating rainfall due to climate change. The study demonstrated how greenhouse gas emissions, “help warm offshore waters—a phenomenon that can magnify the severity of storms and generate more rain, creating bigger floods.”
In a letter to The Financial Times, Prof. Jessika Trancik, postdoc Geoffrey Supran, and graduate student Marco Miotti clarify results from a study the lab released last year that compares emissions of gas and electric vehicles. “Not only do electric cars usually emit less than petrol ones already, but over time, as the carbon footprint of electricity continues to fall, that gap will widen,” the researchers explain.
A study by Prof. Kerry Emanuel finds that storms like Hurricane Harvey, which produced 20 inches of rain, are six times more likely to occur as a result of global warming, reports Robinson Meyers of The Atlantic. Rainfall will worsen because “storms of all types—not just hurricanes—will retain more moisture in a warmer climate,” explains Meyers.
Writing for U.S. News & World Report, Alexa Lardieri highlights how Prof. Daniel Rothman has analyzed carbon changes over the past 540 million years and found that the next mass extinction could start in 2100. Rothman found that, “mass extinctions can occur if changes in the carbon cycle over long time periods outpace global ecosystems' abilities to adapt to those changes.”
A new study by Prof. Daniel Rothman provides evidence that by 2100 the world’s oceans may hold enough carbon to trigger a sixth mass extinction, reports Alyssa Meyers for The Boston Globe. Rothman found that if, “310 gigatons of carbon dioxide are added to the oceans, it could be a crucial tipping point for the carbon cycle.”
Research Scientist Jennifer Morris writes for Salon about her research showing that power companies should invest in carbon-free power sources despite uncertainty about future U.S. emissions limits. Morris and her colleagues found that investing in carbon-free sources, “best positions the United States to meet a wide range of possible future policies at a low cost to the economy.”
A new study co-authored by MIT researchers finds that underground magma triggered the world’s largest mass extinction, reports Howard Lee for The Guardian. Based off their findings, the researchers believe that, “greenhouse gas emissions triggered by magma intrusions...caused the extinction through abrupt global warming and ocean acidification.”
Wired reporter Sian Bradley writes that a study co-authored by MIT researchers shows that the world’s largest mass-extinction was triggered by a massive underground magma pulse. The magma pulse “released dangerous levels of carbon dioxide, methane and sulphur dioxide into the environment and triggered the end of the Permian period.”
MIT researchers have found that by 2050 climate change could deplete water basins and reduce crop yields, reports The Boston Globe’s Alyssa Meyers. If no action is taken to combat climate change, “numerous basins used to irrigate crops across the country will either start to experience shortages or see existing shortages ‘severely accentuated.’”
A study co-authored by MIT researchers shows how efforts to reduce greenhouse gas emissions coupled with policies aimed at improving air quality could help tackle China’s air pollution problems, reports Melissa Lott for Scientific American. The researchers found that “the combination of both vehicle emission standards and an economy-wide carbon price… could pack a strong ‘one-two punch’.”
Writing for The Washington Post, Prof. Maria Zuber, MIT’s vice president for research, outlines how the U.S. can reduce coal emissions without “declaring war on coal communities.” Zuber argues that the U.S. must “commit to helping the workers and communities that are hurt when coal mines and coal plants reduce their operations or shut down.”
In an article for Salon about extreme weather, Paul Rosenberg highlights a new study by MIT researchers that shows climate change could cause California to “experience three more extreme precipitation events per year by 2100, although the number could be reduced by half that if aggressive policy measures are pursued.”
