Global Warming

An analysis by the MIT Sloan Sustainability Initiative and Climate Interactive has found that planting a trillion trees would only prevent 0.27 degrees of warming by 2100, reports Maxine Joselow for The Washington Post. “Trees are great. I personally love to be out in the forests as much as I possibly can,” says Prof. John Sterman. “But the reality is very simple: You can plant a trillion trees, and even if they all survived, which wouldn’t happen, it just wouldn’t make that much difference to the climate.”

Merritt Jenkins MBA '21 co-founded Kodama Systems, a startup developing a semiautonomous timber harvesting machine to remove tree and debris from forests and bury them in an effort to help combat global warming, reports Christopher Helman for Forbes. “Scientists say burying trees can reduce global warming as well—particularly if those trees would otherwise end up burning or decaying, spewing their stored carbon into the air,” writes Helman.

Researchers at MIT have discovered that the ocean’s color has changed considerably in the last 20 years and is “another warning sign of human-driven climate change,” reports Maria Luisa Paul for The Washington Post. “These ecosystems have taken millions of years to evolve together and be in balance,” says Senior Research Scientist Stephanie Dutkiewicz. “Changes in such a short amount of time are not good because they put the whole ecosystem out of balance.”

A study by MIT researchers has found that over 65% of the world’s oceans have changed color over the past 20 years and “human-caused climate change is likely to blame,” reports Rebecca Falconer for Axios. The researchers found that: “Tropical ocean regions near the equator have been particularly affected by this steady change from blue to green,” Falconer notes. 

MIT researchers have found that over the past two decades, the color of the world’s oceans has changed significantly, reports Talib Visram for Fast Company. The change “is likely due to human-induced climate change,” explains Visram. “The color shifts matter in that they signal changes in ecosystem balance, which have the power to disrupt fragile marine food webs.”

CNN reporter Jack Guy spotlights a new study co-authored by researchers at MIT, which shows that the ocean’s color has changed considerably over the last 20 years and human-caused climate change is likely responsible. “All changes are causing an imbalance in the natural organization of ecosystems,” says senior research scientist Stephanie Dutkiewicz. “Such imbalance will only get worse over time if our oceans keep heating.”

Researchers at MIT and elsewhere have discovered that the ocean’s hue has changed significantly over the last 20 years, reports Laura Baisas for Popular Science. “A shift in ocean color is an indication that ecosystems within the surface may also be changing,” writes Baisas. “While the team can’t point to exactly how marine ecosystems are changing to reflect the shift, they are quite sure that human-induced climate change is likely behind it.”

A new study led by a team including researchers at MIT has found that more than half of the world’s ocean has changed color in the last 20 years, reports Coco Liu for Bloomberg. “The color shift could be caused by changes in plankton communities that are critical to the marine food chain,” writes Liu. “And biodiversity isn’t the only thing at stake: The shift could also affect how much carbon dioxide the ocean takes up, since different types of plankton have different abilities to absorb it."

Boston Globe reporter Hiawatha Bray highlights a number of MIT startups that are focused on tackling climate change. “Boston has long been a center of clean energy, driven by innovations spinning out of the Massachusetts Institute of Technology and other universities,” writes Bray.

Al Jazeera spotlights a study co-authored by postdoctoral associate Qian Li that finds that rapidly melting Antarctic ice is slowing down the flow of water through the world’s oceans and “could have a disastrous effect on global climate.”

A study co-authored by postdoctoral associate Qian Li has found that “melting ice around Antarctica will cause a rapid slowdown of a major global deep ocean current by 2050 that could alter the world’s climate for centuries and accelerate sea level rise,” reports Graham Readfearn for The Guardian.

Carlos Casanovas MS ’14 co-founded X1 Wind, a startup that has developed a floating wind turbine prototype, reports Andrew Paul for Popular Science. “Floating wind is set to play a vital role supporting the future energy transition, global decarbonization and ambitious net-zero targets,” says Casanovas.

Prof. Kerry Emanuel and First Street Foundation have found that based on warming climate conditions and patterns, future storms will increase in intensity and travel farther north up the East Coast, reports Leslie Kaufman and Eric Roston for Bloomberg.

Prof. Kerry Emanuel speaks with CNN reporters Ella Nilsen and Renée Rigdon about future hurricane trends. “The bottom line is the models that are being used by the existing [catastrophe] modeling industry are based strictly on historical statistics,” says Emanuel. “The historical record isn’t very long, and it isn’t very good when you get back to before 1970.”

Boston Globe reporter Scott Kirsner spotlights Boston as a potential leader in climate technology for their “incubator spaces like Greentown Labs in Somerville and The Engine in Cambridge.”
