Fluctuating Environment May Have Driven Human Evolution

and has no comments yet.
A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University.

Wind Speeds in Southern New England Declining Inland, Remaining Steady On Coast: Climate Change, Urbanization Among Possible Causes

and has no comments yet.
Oceanographers at the University of Rhode Island have analyzed long-term data from several anemometers in southern New England and found that average wind speeds have declined by about 15 percent at inland sites while speeds have remained steady at an offshore site.

Air Conditioning Consumes One Third of Peak Electric Consumption in the Summer

and has no comments yet.
Air conditioning in homes may account for up to one third of electricity use during periods in the summer when the most energy is required in large cities, according to a study carried out by Carlos III University of Madrid (UC3M) and the Consejo Superior de Investigaciones Científicas (Spanish National Research Council -- CSIC). The research attempts to determine not only the amount of energy that is consumed, but also its environmental impact.

Climate Warming Refuted as Reason for Plant Shifts in High-Profile 2008 Study

and has no comments yet.
Many simple models of plant response to warming climates predict vegetation to find cooler and/or wetter locations, generally moving upslope from their current positions. However, the mechanisms explaining species-specific responses to changes in temperature and water availability are most likely much more complex, according to researchers at Texas Tech University and the United States Geological Survey.

Geoengineering for Global Warming: Increasing Aerosols in Atmosphere Would Make Sky Whiter

and has no comments yet.
One idea for fighting global warming is to increase the amount of aerosols in the atmosphere, scattering incoming solar energy away from Earth's surface. But scientists theorize that this solar geoengineering could have a side effect of whitening the sky during the day. New research from Carnegie's Ben Kravitz and Ken Caldeira indicates that blocking 2% of the sun's light would make the sky three-to-five times brighter, as well as whiter.

1,000 Years of Climate Data Confirms Australia’s Warming

and has 1 comment.
In the first study of its kind in Australasia, scientists have used 27 natural climate records to create the first large-scale temperature reconstruction for the region over the last 1000 years. The study was led by researchers at the University of Melbourne and used a range of natural indicators including tree rings, corals and ice cores to study Australasian temperatures over the past millennium and compared them to climate model simulations

Stream Temperatures Don’t Parallel Warming Climate Trend

and has no comments yet.
A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate.

Arabic Records Allow Past Climate to Be Reconstructed

and has no comments yet.
Corals, trees and marine sediments, among others, are direct evidence of the climate of the past, but they are not the only indicators. A team led by Spanish scientists has interpreted records written in Iraq by Arabic historians for the first time and has made a chronology of climatic events from the year 816 to 1009, when cold waves and snow were normal.

‘Warming Hole’ Delayed Climate Change Over Eastern United States

and has 1 comment.
Climate scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered that particulate pollution in the late 20th century created a "warming hole" over the eastern United States -- that is, a cold patch where the effects of global warming were temporarily obscured.
