Even before the dawn of agriculture, people may have caused the planet to warm up, a new study suggests. Mammoths used to roam modern-day Russia and North America, but are now extinct"”and there's evidence that around 15,000 years ago, early hunters had a hand in wiping them out. A new study, accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union (AGU), argues that this die-off had the side effect of heating up the planet. "A lot of people...

The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash into the oceans. According to this model, proposed in a new paper by Dominic Papineau of the Carnegie Institution for Science, the higher levels of phosphorus would have caused vast algal blooms, pumping extra oxygen into the environment which allowed larger, more complex types of organisms to thrive....

Trees and other plants help keep the planet cool, but rising levels of carbon dioxide in the atmosphere are turning down this global air conditioner. According to a new study by researchers at the Carnegie Institution for Science, in some regions more than a quarter of the warming from increased carbon dioxide is due to its direct impact on vegetation. This warming is in addition to carbon dioxide's better-known effect as a heat-trapping greenhouse gas. For scientists trying to predict global...

Tropical forest destruction accounts for some 20% of global greenhouse gas emissions. But quantifying these emissions has not been easy, particularly for tropical nations. New technology, developed by a team of scientists at Carnegie's Department of Global Ecology, is revolutionizing forest monitoring by marrying free satellite imagery and powerful analytical methods in an easy-to-use, desktop software package called CLASlite. Thus far, 70 government, non-government, and academic...

The Earth's jet streams, the high-altitude bands of fast winds that strongly influence the paths of storms and other weather systems, are shifting"”possibly in response to global warming. Scientists at the Carnegie Institution determined that over a 23-year span from 1979 to 2001 the jet streams in both hemispheres have risen in altitude and shifted toward the poles. The jet stream in the northern hemisphere has also weakened. These changes fit the predictions of global warming models...

Astrobiology Magazine -- In a feat of astronomical and terrestrial alignment, a group of scientists from MIT and Williams College recently succeeded in observing distant Pluto's tiny moon, Charon, hide a star. Such an event had been seen only once before, by a single telescope 25 years ago, and then not nearly as well. The MIT-Williams consortium spotted it with four telescopes in Chile on the night of July 10-11. In addition to assessing whether Charon has an atmosphere, the team expects to...

Cambridge, MA -- The Harvard-Smithsonian Center for Astrophysics (CfA) has taken a key step toward the goal of building and operating a large next-generation telescope through its participation in the joint Giant Magellan Telescope (GMT). The GMT will have a diameter of about 83 feet (25.4 meters), about as wide as the 2004 Christmas tree in Rockefeller Center, New York, is tall. Today, two of the GMT participants--the Carnegie Observatories of the Carnegie Institution, and the University of...

Mount Wilson Observatory -- astronomical observatory located in California on Mt. Wilson, near Pasadena. Mt. Wilson Observatory was founded in 1904 by George E. Hale. Its equipment includes 100-in. (2.5-m) and 60-in. (1.50-m) reflecting telescopes and two solar-tower telescopes 150 ft. (46 m) and 60 ft. (18 m) in length. The most recent addition is the CHARA (Center for High Angular Resolution Astronomy) array operated by Georgia State Univ.; it consists of six 39-in. (1-m) aperture...
