The Unintended Consequences of Geoengineering a Cooler Atmosphere

September 9, 2015


Stimulating Ocean Phytoplankton Growth to Reduce Global Warming

In a newly published study, scientists from MIT reveal unintended consequences of an idea to stimulate ocean phytoplankton growth in order to geoengineer a cooler atmosphere. Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon […]

Brown Study Shows Dogs Evolved With Climate Change

A new study from Brown University shows how dogs evolved in response to changes in climate over the last 40 million years, demonstrating that predators are sensitive to climate change because it alters the hunting opportunities in their habitat. Brown University — Old dogs can teach humans new things about evolution. In Nature Communications a […]

NASA Study Reveals Oceans Temporarily Hide Global Warming

July 12, 2015


Oceans Temporarily Hide Global Warming

A newly published NASA study shows that the recent extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans, accounting for the slowdown in the global surface temperature trend observed during the past decade. Researchers Veronica Nieves, Josh Willis and Bill Patzert of NASA’s Jet Propulsion Laboratory (JPL), […]

New Yale Study Tracks the Impact of Climate Change on Bumblebees

A newly published study from Yale University links climate change to the decline of bumblebee species in North America and Europe. The study, published in the journal Science, found that bumblebee ranges are shrinking in the south and the insects are not moving north. In addition, some species are moving to higher elevations on both […]

New Detailed Global Climate Change Projections from NASA

June 9, 2015


Detailed Global Climate Change Projections

A new dataset from the NASA Earth Exchange shows how temperature and rainfall patterns worldwide may change through the year 2100 because of growing concentrations of greenhouse gases in Earth’s atmosphere. The dataset, which is available to the public, shows projected changes worldwide on a regional level in response to different scenarios of increasing carbon […]

New Research Shows the Rate of Temperature Change is Increasing

March 9, 2015


Climate Change is Speeding Up

A newly published study from the Department of Energy’s Pacific Northwest National Laboratory reveals that the speed with which temperatures change will continue to increase over the next several decades, intensifying the impacts of climate change. College Park, Maryland – An analysis of changes to the climate that occur over several decades suggests that these […]

Small Volcanoes Underestimated in Climate Models

December 3, 2014


Small Volcanoes Make a Difference in Global Warming

A new study from MIT shows that the effects of smaller eruptions have been underestimated in climate models, revealing that relatively small volcanic eruptions can increase aerosol particles in the atmosphere, temporarily mitigating the global warming caused by greenhouse gases. The impact of such smaller eruptions has been underestimated in climate models, the researchers say, […]

MIT Reveals Missing Piece of the Climate Puzzle

In a newly published study, MIT researchers show that a canonical view of global warming tells only half the story and reveal the missing piece of the climate puzzle. In classrooms and everyday conversation, explanations of global warming hinge on the greenhouse gas effect. In short, climate depends on the balance between two different kinds […]
