Man-made soot contributed to warming in Greenland in the early 20th century
08-09-2007 · EurekAlert!New research shows that industrial development in North America between 1850 and 1950 greatly increased the amount of black carbon -- commonly known as soot -- that fell on Greenland's glaciers and ice sheets.

- Antarctic temperatures disagree with climate model predictions
02-15-2007 · EurekAlert!
A new report on climate over the world's southernmost continent shows that temperatures during the late 20th century did not climb as had been predicted by many global climate models. This comes soon after the latest report by the Intergovernmental Panel on Climate Change that strongly supports the conclusion that the Earth's climate as a whole is warming, largely due to human activity. It follows a finding last summer by the same researchers showing no increase in Antarctic precipitation in 50 years.

- El Niño affected by global warming
12-20-2007 · EurekAlert!
A team of IRD scientists and chilean researcher made some unexpected findings about the recent evolution of the ENSO system. Investigation of marine sedimentary drill cores enabled them to retrace the changes in the ENSO's functioning since the XVIIth Century to the present. Results showed a 2°C fall in temperature of the waters of the Humboldt current system for the period 1820-1878. This time corresponds to the end of the Little Ice Age yet coincides with a warming of the Earth.

- Permanent ice fields are resisting global warming
05-16-2007 · EurekAlert!
The small ice caps of Mont Blanc and the Dôme du Goûter are not melting, or at least, not yet. This is what CNRS researchers1 have announced in the Journal of Geophysical Research. At very high altitudes -- above 4200 meters -- the accumulation of snow and ice has varied very little since the beginning of the 20th century. But if summer temperatures increase by a few degrees during the 21st century, the melt could become more marked, and could affect the "permanent" ice fields.

- Solar energy conversion offers a solution to help mitigate global warming
03-06-2007 · EurekAlert!
Solar energy has the power to reduce greenhouse gases and provide increased energy efficiency, says a scientist at the US Department of Energy's Argonne National Laboratory, in a report (view it online) published in the March issue of Physics Today. Last month, The Intergovernmental Panel on Climate Change (IPCC) of the United Nations released a report confirming global warming is upon us and attributing the growing threat to the man-made burning of fossil fuels.

- Films of Mitchell and Kenyon illuminate lefties' decline in Victorian England
09-17-2007 · EurekAlert!
By mining evidence from the classic films made by Mitchell and Kenyon, researchers have confirmed that the left-handed minority suffered something of a setback in Victorian England, at the beginning of the 20th century. In more recent times, lefties' numbers quickly rose again, the researchers report in the Sept. 18, 2007, Current Biology, a publication of Cell Press.

- U of Minnesota study finds gap in health rates between socioeconomic classes unchanged
12-05-2007 · EurekAlert!
Over the past century, the United States has witnessed historic advances in public health and medicine that have contributed to improved health and a significant increase in life expectancy for all socioeconomic groups. But despite 100 years of historic advances, University of Minnesota sociologists have found that the health gap between classes has not changed.

- Volcanic eruptions, ancient global warming linked
04-26-2007 · EurekAlert!
A team of scientists announced today confirmation of a link between massive volcanic eruptions along the east coast of Greenland and in the western British Isles about 55 million years ago and a period of global warming that raised sea surface temperatures by 5 degrees (Celsius) in the tropics and more than 6 degrees in the Arctic.

- PFOA and PFOS detected in newborns
04-24-2007 · EurekAlert!
An analysis of nearly 300 umbilical cord blood samples shows that newborn babies are exposed to perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) while in the womb. PFOS and PFOA are polyfluoroalkyl compounds (PFCs) -- ubiquitous man-made chemicals used in a variety of consumer products, including as a protective coating on food-contact packaging, textiles and carpets, and in the manufacturing of insecticides.

- New adhesive mimics gecko toe hairs
01-30-2008 · EurekAlert!
A new antisliding adhesive developed by UC Berkeley engineers may be the closest man-made material yet to mimic the remarkable gecko toe hairs that enable the tiny lizard's gravity-defying feats. The researchers say that among the future applications for such an adhesive is a robot that could climb up vertical walls and ceilings.
