- New research discredits $100B global warming 'fix'
11-29-2007 · EurekAlert!
Scientists have revealed an important discovery that raises doubts concerning the viability of plans to fertilize the ocean to solve global warming, a projected $100 billion venture. According to Dr. Michael Lutz at UM's Rosenstiel School of Marine and Atmospheric Science, ocean fertilization schemes, which resemble an artificial summer, may not remove as much carbon dioxide from the atmosphere as has been suggested, because they ignore important natural processes.

- Economists help climate scientists to improve global warming forecasts
01-21-2008 · EurekAlert!
Climate scientists are collaborating with experts in economic theory to improve their forecasting models and assess more accurately the impact of rising atmospheric carbon dioxide levels. Although there is broad consensus that there will be a significant rise in average global temperature, there is great uncertainty over the extent of the change, and the implications for different regions.

- Carbon dioxide and the ocean
03-07-2007 · EurekAlert!
Global increases in temperature are just one facet of a much larger issue that scientists at the Rosenstiel School of Marine and Atmospheric Science are dedicated to uncovering. "The Marine Inorganic Carbon Cycle," a paper recently published in the journal Chemical Reviews, attempts to quantify over 60 years of research, reviewing a vast array of science that brings into question the Earth’s natural ability to rebound from the increase in inorganic carbon dioxide in the atmosphere and oceans.

- Southern Ocean could slow global warming
12-05-2006 · EurekAlert!
A new climate model predicts that the Southern Hemisphere Westerly Winds' shift poleward will store carbon dioxide and heat in the deep ocean. Although atmospheric warming will slow, sea level will rise faster.

- Smithsonian scientists report new carbon dioxide study
03-12-2007 · EurekAlert!
Researchers at the Smithsonian Environmental Research Center report that doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil. This response suggests a limited capacity of Earth's ecosystems to stabilize atmospheric CO2 and slow global warming. These findings add a new perspective and a measure of caution suggesting that elevated CO2, by altering microbial communities, may turn a potential carbon sink into a carbon source.

- Engineered weathering process could mitigate global warming
11-07-2007 · EurekAlert!
Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide caused by human emissions. By electrochemically removing hydrochloric acid from the ocean and then neutralizing the acid by reaction with silicate rocks, the researchers say they can accelerate natural chemical weathering, permanently transferring CO2 from the atmosphere to the ocean.

- Rising surface ozone reduces plant growth and adds to global warming
07-25-2007 · EurekAlert!
Scientists have today released new findings that could have major implications for food production and global warming in the 21st century. Experts from the Met Office, the University of Exeter and the Centre for Ecology & Hydrology, have found that projections of increasing ozone near the Earth’s surface could lead to significant reductions in regional plant production and crop yields. Surface ozone also damages plants, affecting their ability to soak up carbon dioxide from the atmosphere and accelerating global warming.

- Past greenhouse warming events provide clues to what the future may hold
02-15-2008 · EurekAlert!
Scientists studying an extreme period of global warming 55 million years ago are piecing together an increasingly detailed picture of its causes and consequences. Their findings describe what may be the best analog in the geologic record for the global changes likely to result from continued carbon dioxide emissions from human activities.

- Fires in far northern forests to have cooling, not warming, effect
11-16-2006 · EurekAlert!
Droughts and longer summers tied to global warming are causing more fires in the Earth's vast northernmost forests, a phenomenon that will spew a steadily increasing amount of carbon dioxide into the atmosphere.

- Antarctic expedition provides new insights into the role of the Southern Ocean for global climate
02-05-2008 · EurekAlert!
In the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of surface waters. This is a result from an Antarctic expedition led by the Alfred Wegener Institute, part of the Helmholtz Association. On Feb. 5, scientists will discuss pressing questions of Antarctic research aboard the icebreaker Polarstern in Cape Town. Federal research minister Dr. Annette Schavan will use the opportunity to meet scientists and South African ministerial colleagues.
