Arctic climate variation under ancient greenhouse conditions
Tiny organisms preserved in marine sediments hold clues about Arctic climate variation during an ancient episode of greenhouse warming.
Based on reconstructions of Arctic climate variability in the greenhouse world of the Late Cretaceous, Sou…
Tropical Atlantic sees weaker trade winds and more rainfall
Earth’s global temperature has been rising gradually over the last decades, but the warming has not been the same everywhere. Scientists are therefore trying to pin down how the warming has affected regional climates because that is what really …
Bering Sea chill yields fatter plankton, pollock diet changes
Despite a 30-year warming trend, the last three years in the Bering Sea have been the coldest on record. A University of Alaska Fairbanks scientist says that the cold temperatures have helped produce larger zooplankton in the Bering Sea, which may a…
Catastrophic drought looms for capital city of Bolivia
Catastrophic drought is on the near-term horizon for the capital city of Bolivia, according to new research into the historical ecology of the Andes.
If temperatures rise more than 1.5 to 2 degrees Celsius (3 to 5 degrees Fahrenheit) above those…

Climate change may create tipping points for populations, not just species
As Earth’s climate warms, species are expected to shift their geographical ranges away from the equator or to higher elevations.
While scientists have documented such shifts for many plants and animals, the ranges of others seem stable.
W…
Volcano fuels massive phytoplankton bloom
Advocates for seeding regions of the ocean with iron to combat global warming should be interested in a new study published today in Geophysical Research Letters. A Canada-US team led by University of Victoria oceanographer Dr. Roberta Hamme describ…
New findings about wind farms could lead to expanding their use
CHAMPAIGN, Ill. — Wind power is likely to play a large role in the future of sustainable, clean energy, but wide-scale adoption has remained elusive. Now, researchers have found wind farms’ effects on local temperatures and proposed strategies fo…
Women more likely than men to accept global warming
EAST LANSING, Mich. — Women tend to believe the scientific consensus on global warming more than men, according to a study by a Michigan State University researcher.
The findings, published in the September issue of the journal Population a…
