Global warming begets more warming, new paleoclimate study finds
Researchers observe a “warming bias” over the past 66 million years that may return if ice sheets disappear.
Geologists take Earth’s inner temperature using erupted sea glass
The results could help scientists unravel the processes underlying plate tectonics.
A new approach to preventing human-induced earthquakes
Applied in the field, a new model reduced quakes from oil and gas processes; could help manage seismic events from carbon sequestration.
How a sudden stratospheric warming affected the Northern Hemisphere
Research from MIT Haystack Observatory finds a stratospheric warming event over Antarctica linked to anomalies in near-Earth space above North America and Europe.
Study highlights long road toward gender parity in the geosciences
Researchers find improvement in relative retention of women but predict decades of sustained effort are required to achieve gender parity.
Pathfinder satellite paves way for constellation of tropical-storm observers
Lincoln Laboratory’s TROPICS satellites will help scientists study extreme tropical weather once all six are launched next year.
New approach could change how we track extreme air pollution events
Study demonstrates the power of low-cost air quality sensors during volcanic eruption.
Imagining the distant past — and finding keys to the future
Associate professor of earth science David McGee studies the atmosphere’s response to paleoclimate changes.
Susan Solomon, scholar of atmospheric chemistry and environmental policy, delivers Killian Lecture
MIT professor describes her path to the Institute, her work on ozone depletion, and her insights on the state of climate policy.
Ozone-depleting chemicals may spend less time in the atmosphere than previously thought
New results point to unexpected, illegal production of several CFCs in recent years.
Tackling air pollution in India and the developing world
PhD student Sidhant Pai works on atmospheric chemistry models that may help policymakers improve air quality in their region.
Cave deposits show surprising shift in permafrost over the last 400,000 years
Study finds Earth’s frozen surfaces became less susceptible to thawing, potentially locking in more carbon than expected.
Ancient atmospheric oxygen sleuthing with ocean chromium
Findings show how the trace metal is chemically altered in the anoxic, modern ocean and provide the basis for investigating paleorecords of atmosphere composition shifts.
Study predicts the oceans will start emitting ozone-depleting CFCs
As atmospheric concentrations of CFC-11 drop, the global ocean should become a source of the chemical by the middle of next century.
Reductions in CFC-11 emissions put ozone recovery back on track
Scientists observe reduction in emissions of banned ozone-depleting chemical after unexpected spike.
