Ozone exacts a particularly heavy toll on people living in economically disadvantaged areas, where industrial and power plants tend to cluster. While policies have been implemented to reduce ozone emissions across the country, they have not yet addressed built-in inequities in the U.S. economy, leaving low-income Americans at greatest risk for health and economic damages.

New toolset evaluates economic impacts of ozone reduction policies for nine income groups.

For the first time, astronomers have observed a star pulsing in response to its orbiting planet. The star, HAT-P-2, pictured, is one of the most massive exoplanets known today. The planet, named HAT-P-2b, tracks its star in a highly eccentric orbit, flying extremely close to and around the star, then hurtling far out before eventually circling back around.

The heart of a far-off star beats for its planet

Scientists observe first planet-induced stellar pulsations.

By studying the remanent magnetizations in ancient meteorites, an MIT team has determined that the solar nebula — the vast of disc of gas and dust that ultimately gave rise to the solar system — lasted around 3 to 4 million years.

Scientists estimate solar nebula’s lifetime

Study finds the swirling gas disk disappeared within the solar system’s first 4 million years.

“There’s no question that carbon dioxide is the biggest contributor to human-caused climate change, so that’s the big focus of mitigation efforts. But there are a number of others that are also significant,” says Jessika Trancik, the Atlantic Richfield Career Development Associate Professor in Energy Studies at MIT’s Institute for Data, Systems, and Society.

Explained: Greenhouse gases

Carbon dioxide isn’t the only one that matters, and the gases vary widely in potency and duration.

The SMAP observations are providing an unprecedented level of detailed, worldwide information on the amount of water in the top 2 inches (5 centimeters) of soil, collected globally every two to three days.

Study tracks “memory” of soil moisture

First year of data from SMAP satellite provides new insights for weather, agriculture, and climate.

Researchers report that warming from short-lived compounds — greenhouse gases such as methane and chlorofluorocarbons, that linger in the atmosphere for just a year to a few decades — can cause sea levels to rise for hundreds of years after the pollutants have been cleared from the atmosphere.

Short-lived greenhouse gases cause centuries of sea-level rise

Through warming effects, methane and other gases impact rising seas long after leaving the atmosphere.

MIT oceanographers have found that some small marine organisms — mostly bacteria — have a surprisingly low limit to the amount of oxygen they need to breathe.

New study sets oxygen-breathing limit for ocean’s hardiest organisms

Bacteria can survive in marine environments that are almost completely starved of oxygen.

A destructive wildfire burned through Canada’s Northern Alberta region, razing neighborhoods in Fort McMurray and displacing tens of thousands of residents.

Climate models may be overestimating the cooling effect of wildfire aerosols

Study finds accounting for year-to-year variability enables more accurate projections of climate change and its impacts.

Dust blowing through the Sahara Desert in 2012. Researchers have found that the plume was far less dusty between 5,000 and 11,000 years ago, containing only half the amount of dust that is transported today.
