Global Warming May Not Lead to Increasingly Stormy Atmosphere

A study led by atmospheric physicists at the University of Toronto finds that global warming will not lead to an overall increasingly stormy atmosphere, a topic debated by scientists for decades. Instead, strong storms will become stronger while weak storms become weaker, and the cumulative result of the number of storms will remain unchanged.

Frequency of Heat Waves Growing Faster in Urban Areas

The frequency of heat waves has increased dramatically over the past 40 years, and the trend appears to be growing faster in urban areas than in less-populated areas around the world, a new study suggests.

CSIRO and Bureau of Meteorology Release Climate Change Projections for Australia

The projections are the most comprehensive ever released for Australia and have been prepared with an emphasis on informing impact assessment and planning in the natural resource management sector. Information has been drawn from simulations based on up to 40 global climate models.

Most Climate Models May Likely Underestimate Degree of Variability

A new Duke University-led study finds that most climate models likely underestimate the degree of decade-to-decade variability occurring in mean surface temperatures as Earth’s atmosphere warms. The models also provide inconsistent explanations of why this variability occurs in the first place.

Atmospheric Warming May Affect Critical Zone at the Base of the Ice

A team of scientists led by Cornell University Earth and Atmospheric Sciences researcher Michael Willis, has published a new paper showing for the first time that meltwater from the surface of an ice cap in northeastern Greenland can make its way beneath the ice and become trapped, refilling a subglacial lake. This meltwater provides heat to the bottom of the ice sheet.

Melting Glaciers Will Release Massive Amounts of Organic Carbon

As the climate warms, glaciers and other terrestrial ice reservoirs will release massive amounts of organic carbon into the water circulation. Just how much and how quickly it will be released is the focus of a recent Nature Geoscience publication.

Researchers Discover Impediments to Long-Term Sequestration of Carbon Dioxide

Carbon sequestration promises to address greenhouse-gas emissions by capturing carbon dioxide from the atmosphere and injecting it deep below the Earth's surface, where it would permanently solidify into rock.

Study Explores Effects of Climate Change on Trees in Boreal Forest

Visitors to northern forests in coming decades probably will see a very different set of trees as the climate warms, a new University of Minnesota study shows.

Study Reveals Flexible Diets of Gentoo Penguins Help Them Tackle Climate Change

In a part of the world that is experiencing the most dramatic increase in temperature and climate change, two very similar species of animals are responding very differently. New research published today suggests that how these species have adapted to co-exist with one another might be to blame.

Melting of Glaciers Will Release Substantial Organic Carbon and Affect Marine Ecosystems

As the Earth warms and glaciers all over the world begin to melt, researchers and public policy experts have focused largely on how all of that extra water will contribute to sea level rise.
