Greenland's ancient forests shed light on stability of ice sheet

...ntarctic ice. I would anticipate that as the Earth warms from man-made climate change, these sources would still contribute to a rise in sea levels." The results also show conclusively that ancient biomolecules from the base of ice cores can be used by scientists to reconstruct the environments hidden un...

Regardless of global warming, rising CO2 levels threaten marine life

...ical effects of carbon dioxide, even if the planet warms less than expected. A new study by University of Illinois atmospheric scientist Atul Jain, graduate student Long Cao and Carnegie Institution scientist Ken Caldeira suggests that future changes in ocean acidification are largely independent of climat...

Microorganisms one part of the solution to energy problem, says report

...sunlight and water to produce the electricity that warms your home, cooks your food, powers your television and washes your clothes. All these futuristic energy technologies may become reality some day, thanks to the work of the smallest living creatures on earth: microorganisms," Wall says. The world fa...

Global warming increases species extinctions worldwide

...r and better than we thought they could as climate warms at their northern range boundaries. So, they're expanding into new territories very rapidly." Parmesan said that pests and diseases are also showing the same northward shifts as other wild animals. Parmesan also found that, at present, scientists...

Same species responds differently to same warming, depending on location

...n and her co-authors show that even if the weather warms the air and water the same amounts in one area as another, the actual effect on mussel body temperatures can vary because of local climate. For example, in Washington, air temperature appears to be more important in driving mussel temperature while i...

Does tropical biodiversity increase as rainforest area expands during global warming?

...lions of years. Diversity increases as the planet warms and decreases as it cools. The mystery is that even when global temperatures vary enormously, average temperatures in the tropics don't change much, so why do we see global temperature patterns reflected in tropical plant diversity?" Jaramillo prop...

Greenhouse theory smashed by biggest stone

...nergy from the sun reaches the earth's surface and warms it, without the greenhouse effect most of this energy is then lost as the heat radiates back into space. However, the presence of so-called greenhouse gases at high altitude absorb much of this energy and then radiate a proportion back towards the ea...

New look at DNA hints at origin of ultraviolet damage

...s happening during the UV energy wave: as sunlight warms our skin, UV photons are absorbed by the bases, causing their electrons to vibrate. These high-energy vibrations nudge the atoms in the bases around, but only along one edge of the DNA ladder at a time. If all goes well, the DNA returns to normal aft...

Burnt coal from the age of dinosaurs sheds light on today's global warming

...d atmosphere, which depletes the oceans of oxygen, warms the planet, and kills off plants and animal species. Now, a new theory holds that OAEs in particular the Toarcian OAE, which occurred about 183 million years ago during the age of dinosaurs are triggered by the burning of vast underground coalfi...

Currents could disrupt ocean food chain

...m the southern tropics into the North Atlantic and warms Europe, will be disrupted. Rather, his study is one of the first to examine what would happen to the ocean food chain if such a disruption did take place. "Phytoplankton are the basis of the entire marine food web," Schmittner said. "They ultimately...

NASA study finds soot may be changing the Arctic environment

...increasing absorbed sunlight. Airborne soot also warms the air and affects weather patterns and clouds. Koch and Hansen?s results suggest a possible mechanism behind the satellite-derived observations of Arctic climate change. They found the timing and location of Arctic warming and sea ice loss in the l...

The book includes epilogues written by institute members Brian Matthews and Peter von Hippel, whose first-hand ac...
