Did ice-melt in the Arctic dry up the Nile 16,000 years ago?

Did ice-melt in the Arctic dry up the Nile 16,000 years ago?

Posted Mon, 28 Feb 2011 14:21:00 GMT by Martin Leggett

In the recent past, melting events in the far north have had dramatic effects across continents further south, scientists say. A megadrought some 16,000 years ago dried up the Nile, and Africa's great lakes, according to a new paper in Science. This event may well have been linked to rapid glacial outpourings from North American ice sheets around the same time.

Droughts and dust storms are being predicted by government scientists studying plant growth and soil erosion in the Southwest United States. Scientists from the US Geological Survey (USGS) and the University of California, Los Angeles studied plants and soils in the Arches and Canyonlands National Parks of south east Utah over a 20 year period.

With the latest report from the Commerce Department clearing NOAA scientists of any wrong-doing in the Climategate affair, it's time to lay the ghost of those false accusations to rest. The way forward lies in a renewed and open dialogue with the public, to rebuild the trust eroded over the affair. As the reality of global warming continues to bite, the need to tell the story honestly and passionately is more apparent than ever.

Weathercasters can be a trusted source for information on global warming but study finds their faith was rocked by 'Climategate' emails. The men and women who bring us our daily TV weather forecasts had their belief in global warming and faith in climate scientists damaged by the 'Climategate' scandal say researchers at George Mason University.

Studies indicate gender discrepancies in climate change. New research indicates that the gender divide has spilled over into the climate change debate, with a French report suggesting that men are bigger eco-offenders than women.

Even if all the world's factories shut down tomorrow and all the cars were taken off the roads, the planet would still get steadily warmer, scientists have warned. That is according to a team of scientists at the University of Washington who believe that, far from being just one of several possible future scenarios, a warmer global climate is now inevitable thanks to the sheer volume of carbon that has been released into the atmosphere since the start of the Industrial Revolution.

Scientists predict that a warming Indian Ocean will create drought conditions in Kenya and Ethiopia. Regular droughts have long been regarded as a feature of eastern Africa, but over the past 20 years the frequency of these droughts has noticeably increased. According to new research published in Climate Dynamics, this is likely to continue as global temperatures continue to rise.

New research in Australia gives real hope that plants can respond to climate change, by rapidly evolving. This is the first study, published in the Journal of Ecology that shows just how widespread this ability is in plants.

New farming methods to reduce greenhouse gases and improve yields

By drilling a field in foot wide strips, nine inches deep, and planting maize and adding nitrate fertiliser at the same time, this increases yields and reduces the amount of nitrate escaping into the atmosphere as nitrous oxide. Although carbon dioxide (CO2) is widely held to be the major contributor to global warming, scientists believe that the contribution of nitrous oxide (N2O) is about 300 times more than CO2.

Scientists believe that a shrinking Arctic ice cap is introducing warmer fresh water into the Atlantic to slow the warming effects of the Gulf Stream and cool down northwest Europe as a consequence. Britain has just suffered its coldest winter for 100 years, bringing freezing, snowy weather that paralysed the country. Scientists say that these icy winters could become a regular feature simply because the world is getting warmer.

Man has been influencing Earth's climate for at least 8,000 years say Swiss researchers. The rise and fall of the Roman Empire; the Black Death, and the colonisation of the Americas all had a significant impact on the environment due to changes in forestation. Early man began by clearing woody areas to improve hunting and gathering opportunities. Next the first farmers had a larger impact by clearing forest for early slash and burn agriculture.

The degree to which the Arctic region can reflect the sun's rays has declined significantly over the past three decades, a team of US researchers have warned. The ongoing loss of snow and ice in the Northern Hemisphere is not just depriving polar bears of their natural habitat, but it is leading to a reduction of the region's solar reflexivity and thereby exacerbating the problem of global warming.

By looking to the past, one team of US scientists believe they can map out the likely changes to the Earth's climate ongoing rises in carbon emissions will bring. one team of US researchers has been looking to the past in order to gain an understanding of the potential consequences of the major rise in the volume of carbon dioxide in the Earth's atmosphere seen since the dawn of the Industrial Revolution. Specifically, the experts at the National Center for Atmospheric Research in Boulder, Colorado, have been asking: When was the last time the Earth's atmosphere contained as much carbon dioxide as it may by the end of this century?

Smaller glaciers, not giant ice caps, tipped to push sea levels up

Melting mountain glaciers rather than the ice sheets of the Antarctic will be the biggest contributor to rising sea levels over the decades ahead, scientists believe. That climate scientists looking into rising sea levels are currently directing their research at the massive ice caps of the Arctic and the Antarctic is hardly surprising.

Scrap the beef, pork, and chicken from your diet if you want to improve your carbon footprint. Edible insects like mealworms, locusts and crickets produce a fraction of the greenhouse gases per kilo of protein than more conventional meals.

Growth rings in fossil and living deep sea corals tell scientists about Atlantic Ocean currents and may provide clues to links between these and global warming. Like tree rings and ice cores, the annual growth rings in deep sea gorgonian corals can tell us about the past environment, and are a new and dependable source of data about the deep ocean. Dr Owen Sherwood, a biogeochemist and lead author of a new study spoke to Earth Times today
