A new study published in the journal Science says that the total impact of switching to natural
gas depends heavily on leakage of methane (CH4) during the natural gas life cycle, and suggests
that more can be done to reduce methane emissions and to improv
As a range of climate change mitigation scenarios are discussed, University of Washington
researchers have found that the injection of sulfate particles into the atmosphere to reflect
sunlight and curb the effects of global warming could pose a severe thr
Forecasts of when a volcano is ready to erupt could be a little closer thanks to work by geologists
at the University of California, Davis, and Oregon State University published online Feb. 16 in
the journal Nature.

Scientists at the University of Liverpool have shown that deep sea fault zones could transport
much larger amounts of water from the Earth's oceans to the upper mantle than previously
Seismologists at Liverpool have estimated that over the age of
Carrying out geoengineering for several decades and then stopping would cause warming at a
rate that will greatly exceed that expected due to global warming, according to a study published
Feb. 18 in Environmental Research Letters.

Research led by a University of Oregon doctoral student in California's Santa Cruz Mountains
has uncovered geologic evidence that supports historical narratives for two earthquakes in the 68
years prior to San Francisco's devastating 1906 disaster.

The release of volatile organic compounds from Earth's forests and smoke from wildfires 3
million years ago had a far greater impact on global warming than ancient atmospheric levels of
carbon dioxide, a new Yale study finds.
The research provides evidenc
