Drawing on records dating back to the journals of Henry David Thoreau, scientists at Harvard University have found that different plant families near Walden Pond have borne the effects of climate change in strikingly different ways.

The diabolical problem of climate change policies requires a global effort to develop a position that strikes a good balance between the costs of mitigation and costs of dangerous climate change.

Researchers from McGill University, along with colleagues from the California Institute of Technology, the Curie Institute in Paris, Princeton University and other institutions, have unearthed crystalline magnetic fossils of a previously unknown species of microorganism that lived at the boundary of the Paleocene and Eocene epochs, some 55 million years ago.

Climate change will have different effects on lakes in warmer and colder regions of the globe. This is the conclusion reached by Japanese and German researchers following studies of very deep caldera lakes in Japan.

The clouds being investigated in this study are known as marine stratocumulus clouds. They tend to form adjacent to continents where deep, cold, upwelling water reaches the sea-surface. This cools the surface air, condensation occurs and clouds form. These clouds are capped by warm air that descends into this region.

Both natural and human-induced influences have changed twentieth-century climate, but their relative roles and regional impacts are still under debate.

As concerns about the effects of global warming continue to mount, a new study published in the December issue of Physiological and Biochemical Zoology finds that an increase in average temperature of only two degrees Celsius could have a devastating effect on populations of Australia's iconic kangaroos.

New research shows rights-based approaches necessary and cost-effective; call for independent advisory and auditing to support UN action on climate change

Will climate change exceed life's ability to respond? Biodiversity in a Warmer World, published in the Oct. 10, 2008 issue of the journal, Science, illustrates that cross-disciplinary research fostered by the Smithsonian Tropical Research Institute in Panama clearly informs this urgent debate.

Scientists focus on hurricane-prone Gulf of Mexico and Caribbean Sea to assess likely changes

Extreme heat events (EHE), or heat waves, are the most prominent cause of weather-related human mortality in the United States, responsible for more deaths annually than hurricanes, lightning, tornadoes, floods and earthquakes combined.

Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.
