In a new study, Prof. Daniel Rothman has predicted that the oceans may hold enough carbon to trigger a sixth mass extinction by 2100, reports Trevor Nace for Forbes. Rothman’s analysis showed that, “given the current rate of carbon being emitted into the atmosphere, we will likely reach a mass extinction threshold by the year 2100.”
HuffPost reporter Thomas Tamblyn writes that Prof. Daniel Rothman has analyzed the Earth’s five previous mass extinctions and found that a sixth could be triggered by 2100. Rothman found that, “if a certain amount of carbon dioxide was added to the oceans on top of its existing levels it would result in a sixth mass extinction event.”
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.”
Prof. Kerry Emanuel writes for The Washington Post about how climate change and U.S. disaster policies are threat-multipliers for natural disasters like hurricanes. “The confluence of rising sea levels and stronger and wetter hurricanes with increasing coastal population and unwise government interference in insurance markets portends ever increasing hurricane disasters."
In an article for The Los Angeles Times, Research Scientist Nick Obradovich writes that the way the human brain functions can make it harder for people to take action on climate change. Obradovich notes that, “we’re likely to do better with policies that generate immediate and tangible benefits.”
Popular Science reporter Kendra Pierre-Louis writes about Prof. Kerry Emanuel’s research showing that climate change could make it harder to predict the intensity of hurricanes. “Storm intensity matters, because a weak storm might just mean staying home for the day, while a strong storm may require evacuation,” Pierre-Louis explains.
Prof. Kerry Emanuel speaks with Miles O’Brien of the PBS NewsHour about the link between climate change and an increase in extreme storm systems. “What all the models and theories seem to agree on, at least globally, at this point is that the frequency of the very high intensity, Category 3 or 4 or 4 events, should go up,” says Emanuel.
Wired reporter Eric Niiler writes that Prof. Kerry Emanuel has found that the probability of a storm like Hurricane Harvey hitting Texas has increased due to warmer waters in the Gulf of Mexico and the lack of high-level winds that normally push such storms out to sea or towards Oklahoma.
Prof. Kerry Emanuel speaks with Washington Post reporter Chris Mooney about how several factors related to climate change, such as sea levels and atmospheric moisture, can help intensify hurricanes like Harvey.
A study co-authored by MIT researchers shows that climate change will cause toxic cyanobacteria algae to increase. The algae, which thrive in warmer conditions, can cause “neurological damage, liver damage, gastrointestinal problems, irritation of eyes, ears and skin, and other health problems,” if ingested, writes Craig Lemoult of WGBH.
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.”
The Economist highlights a study by MIT researchers that shows climate change could cause the flow of the Nile River to become more variable, increasing strain on regional water conflicts. The researchers found that while output could increase by up to 15%, variability would also increase, resulting in, “more (and worse) floods and droughts.”
AP reporter Katy Daigle writes that climate change could drive heat and humidity to extremes in regions of South Asia. Daigle explains that, “with no limit on global warming, about 30 percent of the region could see dangerous wet bulb temperatures above 31 degrees C (88 degrees F) on a regular basis within just a few decades.”
A new study by MIT researchers finds that climate change could cause deadly heat waves in South Asia by the end of the century, reports Nicole Riva for CBC News. The research demonstrates what could happen if “we keep going in this trajectory of no action related to climate change or minimal action,” says Prof. Elfatih Eltahir.
Washington Post reporter Chelsea Harvey writes that MIT researchers have found that millions of people in South Asia could experience deadly heat waves by the end of the century. Without reductions in greenhouse gas emissions, “certain areas of South Asia are projected to occasionally experience extreme conditions exceeding the lethal threshold, including parts of northeastern India and Bangladesh.”
