The researchers scoured tumbled boulders and gravel terraces along the Mackenzie River for signs of the meltwater's passage. The flood "would solve a big problem if it actually happened", says oceanographer Wally Broecker of Columbia University's
Jessop's new method of making oil involves a "switchable" solvent. This solvent is hydrophobic, meaning it mixes with oils and doesn't like water. But when carbon dioxide is added, the solvent becomes hydrophilic,
No one knows exactly how much Earth's climate will warm due to carbon emissions, but a new study this week suggests scientists' best predictions about global warming might be incorrect. The study, which appears in Nature Geoscience, found that climate models explain only about half of the heating that occurred during a well-documented period of rapid global warming in Earth's ancient past. The study, which was published online today, contains an analysis of published records from a period of rapid climatic warming about 55 million years ago known as the Palaeocene-Eocene thermal maximum, or PETM.
That now brings up another issue. A previous post on the Antarctic ice core, established that every 100,000 years or so we swing by Sirius and get bathed in ultraviolet radiation for a thousand years or so. The effect of this is to essentially melt out a large part of the ice caps and add perhaps another couple of hundred feet of sea level. The temperature will rise several degrees on average and that surplus must migrate north. Far more importantly huge amounts of water will find its way into the atmosphere introducing enough rain to establish tropical conditions almost to the poles themselves. It also means a massive expansion of Amazon tropical rainforest like conditions far to the north. The Mississippi valley, the Sahara, the Outback, the Middle East will all become saturated swamplands fully able to support their own populations of crocodiles.
The head appeared over bushes ten feet tall. It was about the size of a beer keg and was shaped like that of a tapir, as if the snout was used for pulling things or taking hold of them. The eyes were small and dull and set in like those of an alligator. Despite the half dried mud we could see that the neck, which was very snakelike, only thicker in proportion, as rough knotted like an alligator's sides rather than his back.
"If our prediction is correct, Solar Cycle 24 will have a peak sunspot number of 90, the lowest of any cycle since 1928 when Solar Cycle 16 peaked at 78," says panel chairman Doug Biesecker of the NOAA Space Weather Prediction Center.
As expected THEMIS continues to surprise us as it maps the plasma surrounding the Earth. We have now discovered that huge tornado like plasma funnels shape electrical flow into our ionosphere to produce the Northern Lights. And that pretty well ends
Based on initial test and analysis, the Company currently estimates that it can deliver advanced (second generation) fuels from biomass at a cost of less than $ 2 per gallon of ethanol-equivalent fuel in facilities processing about 70,000 tonnes of b
the Einstein@Home project is beginning to analyze data taken by the PALFA Consortium at the Arecibo Observatory in Puerto Rico. The Arecibo Observatory is the largest single-aperture radio telescope on the planet and is used for studies of pulsars
Alaska's Mount Redoubt volcano erupted five times overnight, sending an ash plume more than 9 miles into the air in the volcano's first emissions in nearly 20 years. Residents in the state's largest city were spared from falling ash, thou
