Arctic Warming Linked with Severe Weather in Other Countries

Professor Edward Hanna and PhD student Richard Hall, from the University of Sheffield’s Department of Geography, are part of a select group of international climate scientists investigating links between Arctic climate change and extreme weather in the northern mid-latitudes.

Better Understanding of Relationship Between Stratosphere-Troposphere Layers Could Boost Climate Change Projections

Long range weather forecasts and climate change projections could be significantly boosted by advances in our understanding of the relationship between layers of the Earth's atmosphere -- the stratosphere and troposphere.

Climate Change Impacts on Water Cycle of Midwestern US Remain Uncertain

Will climate change make the U.S. Midwest drier or wetter during the summer growing season? A new Dartmouth-led study finds that the answer remains uncertain.

Ocean Microbes Could Influence Cloud Properties and Impact Climate

A factor that determines the properties of clouds that help moderate the planet’s temperature may be decided in the oceans.

Researchers Find Clear Indications of Warming in the Upper Troposphere

Researchers have published results in Environmental Research Letters confirming strong warming in the upper troposphere, known colloquially as the tropospheric hotspot. The hot has been long expected as part of global warming theory and appears in many global climate models.

Climate Change Contributes to Drop in Ozone Levels

Researchers at the University of Houston have determined that climate change - in the form of a stronger sea breeze, the result of warmer soil temperatures - contributed to the drop in high-ozone days in the Houston area.

Study Estimates Quantity and Form of Organic Carbon Exported by Rivers to the Ocean

Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the removal and long-term storage of carbon, including the world's river systems, which transport decaying organic material and eroded rock from land to the ocean.

Actual SOA Particles are Highly Viscous Semi-Solids Having Complex Compositions and Multifaceted Structures

For the past 20 years, a large portion of the particles measured in the atmosphere were missing from models. At best, models were able to explain one-tenth of the carbon-rich secondary organic aerosols, or SOA, measured in the air. The problem turned out to be a series of fundamental assumptions used in the models due to a lack of experimental data.

Researchers Discover How Abrupt Global Warming Event Triggered Highly Corrosive Deep-Water Current

Around 55 million years ago, an abrupt global warming event triggered a highly corrosive deep-water current through the North Atlantic Ocean. The current's origin puzzled scientists for a decade, but an international team of researchers has now discovered how it formed and the findings may have implications for the carbon dioxide emission sensitivity of today's climate.

Dual Mechanism Slows Peat Decay and Helps Reduce Carbon Emissions

Duke University scientists have discovered a previously unknown dual mechanism that slows peat decay and may help reduce carbon dioxide emissions from peatlands during times of drought.
