Researchers at MIT have developed a conceptual design for a system that can efficiently produce “solar thermochemical hydrogen,” reports Xinhua. “The system harnesses the Sun's heat to directly split water and generate hydrogen -- a clean fuel that can power long-distance trucks, ships, and planes, while in the process emitting no greenhouse gas emissions.”
Writing for The Hill, Andre Zollinger, senior policy manager at J-PAL Global, makes the case that “current attention to air pollution can be transformational for how we tackle climate change. Policy leaders in the U.S. and abroad should seize this moment of reckoning over our common struggle for clean air as an opportunity to focus on policies that are known to curb air pollution and simultaneously combat climate change.”
Sean Hunt MS ’13 PhD ’16 co-founded Solugen, a startup working to develop industrial chemicals with environmentally friendly ingredients, reports David H. Freedman for Newsweek. “The company's goals over the next seven years are to reduce the carbon emissions released by industry into the environment by an amount equivalent to eliminating 2 million cars, and to make enough bioplastic to get rid of 5 billion non-degradable plastic bottles,” writes Freedman.
MIT researchers have developed a new satellite observation technique that can gauge how fast rivers flowed on Mars billions of years ago and how fast they currently flow on Titan, Saturn’s largest moon, reports Talia Lissauer for The Boston Globe. “We can use these other worlds to help us understand what keeps planetary climate stable, or in some cases, what allows planetary climate to change really drastically over time like on Mars,” says Prof. Taylor Perron.
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.”
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.”
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."
Researchers from MIT have developed a new satellite observation technique that can help gauge the strength of ancient rivers on Mars and active liquid methane rivers on Titan, Saturn’s largest moon, reports Jamie Carter for Forbes. “What’s exciting about Titan is that it’s active, and on Mars, it gives us a time machine, to take the rivers that are dead now and get a sense of what they were like when they were actively flowing,” says Prof. Taylor Perron. “With this technique, we have a method to make real predictions for a place where we won’t get more data for a long time.”
Using a new satellite observation technique, researchers from MIT and elsewhere have determined the flow of dried-up rivers on Mars and currently active liquid methane rivers on Titan, Saturn’s largest moon. “Both kinds are of scientific interest because they could reveal the role rivers play in shaping the worlds’ environments,” reports Isaac Schultz for Gizmodo.
Sergey Paltsev, deputy director of the MIT Joint Program on the Science and Policy of Global Change, speaks with WCVB-TV about the pressing need for action to address the climate crisis, following the Earth’s hottest days on record. Paltsev emphasized that he hopes the record-shattering heat will motivate policymakers and the general public to take action to prevent extreme climate events in the future.
Researchers from MIT and elsewhere have found that new building codes put in place to combat climate change could impact home affordability in the greater Boston area, reports Paula Ebben for CBS Boston, “If widely adopted, [the codes] could add up to $23,000 to the cost of an average home, leaving an additional 33,000 Massachusetts residents priced out of the market,” writes Ebben.
