In this video, Nicholas Cardona reports for USA Today that Prof. Daniel Rothman has predicted that the Earth’s next mass extinction event could begin in 2100, based on an analysis of the last five mass extinction events. Rothman found that, “each of the events saw high increases in global carbon. That leads to a destabilized ecosystem,” Cardona reports.
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.”
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.”
Justin Worland reports for TIME on a new study by MIT researchers that shows by the end of the century millions of people living in South Asia could experience temperature and humidity conditions that exceed habitable levels. “The disastrous scenario could be avoided if countries meet their commitments to keep temperatures from rising more than 2°C (3.6°F) by 2100.”
MIT researchers have found that by 2100, climate change could cause deadly heat waves in parts of South Asia, reports Chris Arsenault for Reuters. “Climate change is not an abstract concept, it is impacting huge numbers of vulnerable people,” explains Prof. Elfatih Eltahir. “Business as usual runs the risk of having extremely lethal heat waves.”
Writing for The Guardian, Damian Carrington highlights a new study by Prof. Elfatih Eltahir that shows that without reductions in carbon emissions, millions of people living in South Asia could face extreme heatwaves. “The problem is very alarming but the intensity of the heatwaves can be reduced considerably if global society takes action,” says Eltahir.
BBC News reporter Matt McGrath writes that MIT researchers have found climate change could cause deadly heat waves in South Asia by the end of the century. "This is something that is going to impact your most vulnerable population in ways that are potentially pretty lethal,” explains Prof. Elfatih Eltahir. “But it is avoidable, it is preventable."
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.”
