For a better understanding of how forest fires behave and interact with climate, scientists are turning to the trees. A new study out of UC Irvine shows that differences in individual tree species between Eurasia and North America alter the continental patterns of fire - and that blazes burning the hottest actually cool the climate.
Sceptics who still doubt anthropogenic climate change have now been stripped of one of their last-ditch arguments: It is true that there has been a warming hiatus and that the surface of the earth has warmed up much less rapidly since the turn of the millennium than all the relevant climate models had predicted.
The Earth's crust under Iceland is rebounding as global warming melts the island's great ice caps, a University of Arizona-led team reports in an upcoming issue of Geophysical Research Letters.
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.
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.
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.
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.
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.
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.
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.
