Earth and atmospheric sciences

A team of scientists, including MIT researchers, has analyzed the measurements made by the IceCube Neutrino Observatory and found no evidence of the sterile neutrino, a new type of neutrino, reports Brendan Cole for Wired. 

Amina Khan of The Los Angeles Times writes that a team of scientists, led by postdoc Julien de Wit, has conducted an atmospheric study of two Earth-sized exoplanets and found that they are rocky and have thin atmospheres. The findings “lend growing support to the idea that such planets might potentially be friendly to life.”

EAPS postdoc Julien de Wit and his colleagues have analyzed the atmospheres of two potentially habitable exoplanets, reports Alan Yuhas for The Guardian. Based off their observations, de Wit explains that the atmospheres of the planets are probably similar to a “terrestrial planet like Mercury, Venus, Mars and Earth.”

A double transit of two Earth-sized exoplanets allowed an international team of scientists, led by postdoc Julien de Wit, to conduct an atmospheric analysis, writes Vivian Wang for The Boston Globe. The researchers found that “the planets have rocky, rather than gaseous, terrain, and compact, rather than loose, atmospheres — all further indication that they are potentially habitable.” 

A study conducted by researchers with the Singaore-MIT Alliance for Research and Technology examines how coal use could cause water strain in parts of Asia, writes Audrey Tan for The Straits Times. The study’s findings suggest that higher coal use “could suppress rainfall in China, India and across South-east Asia,” explains Tan.

A new study co-authored by Prof. Susan Solomon provides evidence that the hole in the ozone layer over Antarctica is starting to heal, reports Pilita Clark for the Financial Times.  Clark explains that the findings suggest that “more than half the shrinkage in the ozone hole is due to the reduction in atmospheric chlorine coming from CFCs.” 

A recent study shows that the ozone hole has shrunk by more than 4 million square kilometers since the Montreal Protocol banned the use of CFCs, writes David Abel for The Boston Globe. “This shows that international cooperation on environmental problems can work and be effective,” says lead author Prof. Susan Solomon. 

Eric Hand writes for Science that a recent study led by Prof. Susan Solomon shows the effectiveness of the Montreal Protocol, which banned the production of CFCs. The study also explains that the record-sized ozone hole in October 2015 was caused by a volcano eruption in Chile, writes Hand.

Research by MIT scientists shows that 30 years after banning CFCs the ozone hole is shrinking, writes Aaron Sidder for National Geographic. “These findings suggest that ozone healing is right on pace with the expected timeline,” explains Sidder.

Scientists have found that the Antarctica ozone hole is showing signs of healing and is forming at a slower rate, writes Megan Daley for The Los Angeles Times. Prof. Susan Solomon explains that the findings show that the Montreal Protocol, which banned the use of ozone-destroying chloroflourocarbons, “produced the positive result that we hoped for.”

Scientists have found evidence that the ozone hole over Antarctica is getting smaller and forming later in the year, reports Seth Bornstein for the Associated Press. Prof. Susan Solomon, lead author of the study, says the findings are a "tremendous cause for hope" for fixing other environmental problems. 

USA Today reporter Doyle Rice reports that a team of researchers led by MIT Prof. Susan Solomon has found that the Antarctica ozone heal is beginning to heal. “The discovery shows global attempts to improve Earth's environment can work, providing a template for how humanity could tackle the exponentially larger issue of climate change,” Doyle writes. 

New York Times reporter Henry Fountain writes that researchers have found evidence that the ozone hole over Antarctica is getting smaller. “We are seeing the planet respond as expected to the actions of people,” says Prof. Susan Solomon. “It’s really a story of the public getting engaged, policy makers taking action, and business getting engaged.”

Researchers from MIT and other institutions have found that the Antarctic ozone hole has begun to heal, reports Chris Mooney for The Washington Post. “If you use the medical analogy, first the patient was getting worse and worse, and then the patient is stabilized, and now, “explains Prof. Susan Solomon, “the patient is really starting to get better.”  

Researchers from MIT and the University of Washington have found that centuries-old ocean currents have been keeping the Southern Ocean cold, reports Sarah Emerson for Motherboard. The researchers found that “Antarctica’s unique currents and strong westerly winds are constantly dredging up ancient currents from deep beneath the ocean’s surface.”
