MIT researchers have launched a new project, Treepedia, to catalogue the density of the tree canopy in cities around the world, reports Feargus O’Sullivan for CityLab. O’Sullivan explains that the project is aimed at making “issues of urban and environmental planning (and the data that underpins them) more accessible for non- or semi- professionals.”
CBC News reporter Laura DaSilva writes that MIT researchers have launched a project, called Treepedia, to measure the percentage of land covered by trees in urban areas. Using Google Street View, “the researchers measured the percentage of land covered by trees in 12 cities across the world.”
UPI reporter Brooks Hays writes that MIT researchers have developed a new model that helps predict the frequency of extreme precipitation events. The researchers found that “a rise in global temperature of 4 degrees Celsius will yield an extra three extreme precipitation events per year in California by the end of the century.”
In their round up of the top science stories of 2016, Science News highlighted several MIT research breakthroughs. The top story of the year was the successful detection of gravitational waves by researchers from MIT, Caltech and the LIGO Scientific Collaboration. Another highlight was the discovery by Prof. Susan Solomon that the hole in the ozone layer over Antarctica is shrinking.
A study co-authored by Prof. Christopher Knittel finds that technological advances are needed to reduce the use of oil in the car industry, according to The Economist. The researchers found that “the price of batteries to power EVs would need to fall by a factor of three, and they would need to charge much faster.”
Writing for The Washington Post, Prof. Jessika Trancik examines how federal policy could impact global progress on responding to climate change. “We estimate that the U.S. can achieve the majority share of its original 2025 emissions reduction target even with federal policy changes,” Trancik explains.
MIT, Boston Medical Center and Post Office Square Redevelopment Corp. are joining forces to purchase solar power from a new solar farm being constructed in North Carolina, writes Jessica Bartlett for the Boston Business Journal. Bartlett writes that the project is “the largest renewable-energy project ever to be constructed in the U.S. through an alliance of different buyers.”
BostInno reporter Olivia Vanni writes that MIT, Boston Medical Center and Post Office Square Redevelopment Corp. have formed an alliance to purchase energy from a new solar power installation. “The amount of yearly clean energy generated from the project is 146 gigawatt-hours, which could lead to a reduction of 119,500 metric tons of carbon dioxide emissions,” writes Vanni.
Writing on carbon pricing for The Wall Street Journal, Mark Muro cites MIT research by Professor Valerie Karplus and graduate student Jesse Jenkins. Their research finds that the “‘binding constraints’ of politics keep jurisdictions’ legislated carbon prices low.”
A team of MIT researchers has received an EPA grant to install a network of air quality sensors to study Hawaii’s volcanic smog, reports Greenwire’s Sean Reilly. The sensors will provide residents with real-time information as well as “a data set that can be used to explore pollutant variability and other topics,” explains Reilly.
Prof. Elfatih Eltahir speaks with the BBC’s Ed Butler about whether desalination could be an effective remedy for water shortages in the Middle East. Eltahir notes that current desalination methods use “a lot of energy to basically distill water…and could have very high costs and could contribute to the potential for global warming.”
The EPA has awarded a team of MIT researchers a grant to create a network of low-cost, air pollution sensors, according to the Associated Press. The network will test and track emissions from the Kilauea volcano in Hawaii, which emits high levels of sulfur dioxide, reducing air quality and negatively impacting human health and crops.
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.
