No Escape: There's global warming on Mars too
04-07-2007 · Science News OnlineThe overall darkening of Mars' surface in recent decades has significantly raised the Red Planet's temperature, a possible cause for the substantial, recent shrinkage of the planet's southern ice cap.

- Space sunshade might be feasible in global warming emergency
11-03-2006 · EurekAlert!
Developing renewable energy is the only permanent solution to global warming, University of Arizona astronomer Roger Angel concludes. But should Earth be faced with an abrupt climate crisis, a space sunshade is a technically feasible solution.

- Global warming is reducing ocean life, increasing atmospheric carbon dioxide, say scientists
12-06-2006 · EurekAlert!
Alarming new satellite data show that the warming of the world's oceans is reducing ocean life while contributing to increased global warming.

- 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.

- 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.

- Northern forests less effective than tropical forests in reducing global warming
06-21-2007 · EurekAlert!
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science.

- Role reversal as humans suck life out of leeches
09-05-2007 · EurekAlert!
Global warming may be to blame for the gradual extinction of cold-loving species, and the European land leech in particular, according to a study which will be published in the December issue of Springer’s journal Naturwissenschaften. The findings show that human-induced temperature increases over a 40-year period in the Graz region of Austria may have led to the near extinction of the local land leech Xerobdella lecomtei.

- New study increases concerns about climate model reliability
12-11-2007 · EurekAlert!
A new study comparing the composite output of 22 leading global climate models with actual climate data finds that the models do an unsatisfactory job of mimicking climate change in key portions of the atmosphere. This research, published online Wednesday in the Royal Meteorological Society's International Journal of Climatology, raises new concerns about the reliability of models used to forecast global warming.
