Earth Changes
University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide, according to a paper published online by the Proceedings of the National Academy of Sciences on Nov. 24.
"Of the variables the study examined that are linked to changes in ocean acidity, only atmospheric carbon dioxide exhibited a corresponding steady change," said J. Timothy Wootton, the lead author of the study and Professor of Ecology and Evolution at the University of Chicago.
The increasingly acidic water harms certain sea animals and could reduce the ocean's ability to absorb carbon dioxide, the authors said. Scientists have long predicted that higher levels of atmospheric carbon dioxide would make the ocean more acidic. Nevertheless, empirical evidence of growing acidity has been limited.

Dead mussels as well as live mussels with open, eroded shells are possible symptoms of stress from declining ocean pH and increasing acidity.

Second only to the melting of the Arctic ice and those "drowning" polar bears, there is no scare with which the global warmists, led by Al Gore, more like to chill our blood than the fast-vanishing glaciers of the Himalayas, which help to provide water for a sixth of mankind. Recently one newspaper published large pictures to illustrate the alarming retreat in the past 40 years of the Rongbuk glacier below Everest. Indian meteorologists, it was reported, were warning that, thanks to global warming, all the Himalayan glaciers could have disappeared by 2035.

There was something peculiar about dolphins that stumped prolific British zoologist Sir James Gray in 1936.
He had observed the sea mammals swimming at a swift rate of more than 20 miles per hour, but his studies had concluded that the muscles of dolphins simply weren't strong enough to support those kinds of speeds. The conundrum came to be known as "Gray's Paradox."
For decades the puzzle prompted much attention, speculation, and conjecture in the scientific community. But now, armed with cutting-edge flow measurement technology, researchers at Rensselaer Polytechnic Institute have tackled the problem and conclusively solved Gray's Paradox.
"Sir Gray was certainly on to something, and it took nearly 75 years for technology to bring us to the point where we could get at the heart of his paradox," said Timothy Wei, professor and acting dean of Rensselaer's School of Engineering, who led the project. "But now, for the first time, I think we can safely say the puzzle is solved. The short answer is that dolphins are simply much stronger than Gray or many other people ever imagined."

A single frame from a research video tracking the flow of water around Primo, a retired U.S. Navy bottlenose dolphin, with visualized information illustrating the water flow. The arrows indicate in which direction the water is moving, and the colors indicate the speed. The red and dark blue arrows signify the fastest-moving water.

Naimona'nyi's frozen ice cap lacks critical radioactive signal.
Naimona'nyi's frozen ice cap lacks critical radioactive signal.
In a paper just published in Geophysical Research Letters, researchers from the Byrd Polar Research Center explain that levels of tritium, beta radioactivity emitters like strontium and cesium, and an isotope of chlorine are absent in all three cores taken from the Naimona'nyi glacier 19,849 feet (6,050 meters) high on the southern margin of the Tibetan Plateau.
"We've drilled 13 cores over the years from these high-mountain regions and found these signals in all but one - this one," explained Lonnie Thompson, University Distinguished Professor of Earth Sciences at Ohio State.
The absence of radioactive signals in the top portion of these cores is a critical problem for determining the age of the ice in the cores. The signals, remnants of the 1962-63 Soviet Arctic nuclear blasts and the 1952-58 nuclear tests in the South Pacific, provide well-dated benchmarks to calibrate the core time scales.
New research shows that we should be looking to the ground, not the sky, to see where climate change could have its most perilous impact on life on Earth.
Scientists at the University of Toronto Scarborough have published research findings in the journal Nature Geoscience that show global warming actually changes the molecular structure of organic matter in soil.
"Soil contains more than twice the amount of carbon than does the atmosphere, yet, until now, scientists haven't examined this significant carbon pool closely," says Myrna J. Simpson, principal investigator and Associate Professor of Environmental Chemistry at UTSC. "Through our research, we've sought to determine what soils are made up of at the molecular level and whether this composition will change in a warmer world."

For several years I have been curious and concerned about reports from many parts of the world that bee colonies were vanishing or dying. Because of their ability to pollinate fruit and vegetables bees are of enormous importance to mankind. Finally a breakthrough in understanding this problem has appeared on the scene. Whether this solves the whole bee problem or is simply one part of a more complex issue remains to be seen.
An article in Natural News by David Gutierrez on September 30, 2008 has linked the bee die-off in the Baden-Wurttemburg state of Germany to direct contact with the insecticide clothianidin found on corn seeds (German Research Center for Cultivated Plants). This pesticide had been applied to rapeseed and sweet cornseeds in the Rhine River Valley. Piles of dead bees were discovered at the entrance of hives in early May 2008. Clothianidin was found in the tissues of 99% of the dead bees. This is the time when corn seeding takes place according to Walter Haefeker, president of the European Professional Beekeeping Association. The Julius Huehn Institute (federal agricultural research agency) stated "it can be unequivocally be concluded that a poisoning of the bees is due to a rub-off of the pesticide ingredient clothianidin from corn seeds." This chemical is estimated to have killed two-thirds of the bees in this state.

It's the ultimate form of solar power: eat a plant, become photosynthetic. Now researchers have found how one animal does just that.
Elysia chlorotica is a lurid green sea slug, with a gelatinous leaf-shaped body, that lives along the Atlantic seaboard of the US. What sets it apart from most other sea slugs is its ability to run on solar power.
Mary Rumpho of the University of Maine, is an expert on E. chlorotica and has now discovered how the sea slug gets this ability: it photosynthesises with genes "stolen" from the algae it eats.
