Climate change

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. 

Meghna Chakrabarti of WBUR’s Radio Boston speaks to Puerto Rico Governor Ricardo Rossello ‘01 about the needs and the status of the island, plans to rebuild infrastructure, and how the new tax plan will affect Puerto Rico’s economy. Rossello was in Boston for the MIT Conference on the Resilient Reconstruction of the Caribbean. 

Boston Globe reporter David Abel reports on Puerto Rico Governor Ricardo Rosselló's ’01 visit to MIT for the Conference for the Resilient Construction of the Caribbean. The governor shared his frustration with proposed federal tax policies while expressing optimism about working with MIT on solutions for climate-resilient reconstruction after this fall’s hurricanes. 

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.

Prof. Kerry Emanuel released a new paper that analyzes the impact of Hurricane Harvey, writes  Bloomberg’s Eric Roston. Emanuel found that “Harvey’s rainfall in Houston was ‘biblical’ in the sense that it likely occurred around once since the Old Testament was written.”

A recent study from Prof. Kerry Emanuel suggests that, due to climate change, “massive hurricanes like Harvey are expected to strike Houston and Texas with much greater frequency in the future than they do now,” writes Deborah Netburn for the Los Angeles Times.

Seth Borenstein of the Associated Press reports on a new study by Prof. Kerry Emanuel, which finds that hurricanes with extreme rainfall could become common as a result of global warming. Borenstein explains that the odds of 20 inches of rain occurring over a large area of Texas is “6 in 100 and by 2081, those odds will be 18 in 100.”

A study by Prof. Kerry Emanuel finds that climate change will triple the likelihood of storms with 20 inches of rainfall hitting Texas, writes Doyle Rice for USA Today. Using computer models of past, present, and future storms, Emanuel “hurried the study to help Houston officials think about what conditions they should consider when they rebuild,” Rice explains.

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.

Chris Mooney at The Washington Post writes about a new study from Prof. Kerry Emanuel, which suggests that the extreme rains during Hurricane Harvey were made more likely by climate change, and “such extreme flooding events will only become more frequent as the globe continues to warm.”

New Scientist reporter Michael Le Page writes that a study co-authored by Prof. Kerry Emanuel finds that while in the future hurricanes may be more likely to miss New York City, the city could experience 15-metre storm surges. “The result is peculiar to New York City,” says Emanuel. “Almost everywhere else, including Boston, we see an increase in surge heights and storminess.”

A new study co-authored by research affiliate Judah Cohen shows that the extreme winters of the past few years can be attributed to the warming Arctic, writes Kendra Pierre-Louis for Popular Science. While most associate warmer temperatures with climate change, “a warming climate sends ripples of change across the entire climate system, which sometimes means some very cold winters.”

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.”
