Climate change

“This is not saying that disaster occurs the next day,” says Professor Daniel Rothman about his new study. “It’s saying that, if left unchecked, the carbon cycle would move into a realm which would be no longer stable, and would behave in a way that would be difficult to predict. In the geologic past, this type of behavior is associated with mass extinction.”

Mathematics predicts a sixth mass extinction

By 2100, oceans may hold enough carbon to launch mass extermination of species in future millennia.

One proposed application of the firebrick-based thermal storage system is depicted in this hypothetical configuration, where it is coupled to a nuclear power plant to provide easily dispatchable power.

Firebricks offer low-cost storage for carbon-free energy

Ancient technology could be used to level electricity prices for renewables.

“The goal was trying to understand the chemistry associated with organic particulate matter in a forested environment,” associate professor Jesse Kroll explains. “We took a lot of measurements using state-of-the-art instruments we had developed.” The team also took many photos while in Colorado. Pictured on the bottom right is Douglas Day, CU researcher and organizer of the field campaign....

Team gathers unprecedented data on atmosphere’s organic chemistry

Colorado forest study provides clearest-ever picture of gases released into the atmosphere and how they change.

Texas Army National Guardsmen help Houston residents affected by flooding caused by Hurricane Harvey board a military vehicle. "With an event like this," says MIT associate professor of urban planning Brent Ryan, "it becomes viscerally evident which residential areas are absolutely not safe from even moderate flooding."

3 Questions: Brent Ryan on Hurricane Harvey’s implications for U.S. cities

Stranded in Houston by hurricane floodwaters, an MIT associate professor sees firsthand how design and policy decisions affected the storm’s impact.

Scientists in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS) have for the first time determined the strength of the stratosphere’s circulation, based on observations of key chemicals traveling within this atmospheric layer.

Strength of global stratospheric circulation measured for first time

Estimate will help gauge hang time of greenhouse gases, water vapor, and ozone in upper atmosphere.

A national study by MIT researchers provides one of the first in-depth looks at the characteristics of places that have adopted food recycling, revealing several new facts in the process.

Study: For food-waste recycling, policy is key

Successful programs aren’t limited to well-off towns with strong environmental movements.

Researchers have found there is often a strong case for building relatively modest, incremental additions to water infrastructure in advanced countries, rather than expensive larger-scale projects that may be needed only rarely.

Case study suggests new approach to urban water supply

One drought remedy: Keep infrastructure fast, cheap, and under control.

A new study shows that without significant reductions in carbon emissions, deadly heat waves could begin within as little as a few decades to strike regions of India, Pakistan, and Bangladesh. This map shows the maximum wet-bulb temperatures (which combine temperature and humidity) that have been reached in this region since 1979.

Deadly heat waves could hit South Asia this century

Without action, climate change could devastate a region home to one-fifth of humanity, study finds.

Geologists report that about 251.9 million years ago, a huge pulse of magma rose up through the Earth, in a region that today is known as the Siberian Traps.

Underground magma pulse triggered end-Permian extinction

Study ties specific interval during an extended period of volcanism to Earth’s most severe mass extinction.
