When ice ages held Europe in their grip, Africa also felt the pinch - though in a different way.
It has long been suspected that there is a connection between the west African monsoon and climate at higher latitudes - especially over geological timescales, says David Lea at the University of California, Santa Barbara. "But until now, there hasn't been enough supporting evidence." Now Lea, with team leader Syee Weldeab and colleagues, has reconstructed the most detailed history of the monsoon yet, spanning 155,000 years and two ice ages. The team analysed the amount of barium in plankton shells found in an ocean sediment core drilled beneath the Gulf of Guinea. Barium is found in freshwater run-off from the river Niger, says Lea, and is a gauge of past run-off levels and monsoon intensities. When the northern latitudes were frozen over, monsoon rains were much weaker, only gaining strength again when the temperatures in the north increased, the team found. They also discovered big swings in monsoon activity over timescales as small as 100 years, linked to rapid climate change caused by changes in ice sheet size (Science, vol 316, p 1303). "Something that happens right up in the poles can have a dramatic effect on the climate in the tropics," says Lea. |

Jupiter's cloud patterns are undergoing dramatic changes, reveal new images by the Hubble Space Telescope. Similar transformations of the giant planet's clouds have been witnessed before, but never in such detail – and they have never been explained. Hubble has been keeping an eye on Jupiter to provide context for close-up observations made by NASA's New Horizons spacecraft, which flew by the solar system's largest planet in February on its way to Pluto. Some changes were already evident in January, when Jupiter became observable again after a period when it was too close to the Sun in the sky for Hubble to image. At that time, cloud bands around its equator that had been whitish for the past 15 years or so were noticeably darker. Then, between 25 March and 5 June, a white band in the planet's northern hemisphere turned brown, while a gap in the cloud layer produced a serpent-shaped dark streak in the same area. White bands in the southern hemisphere seem to be changing colour now, too, says Amy Simon-Miller of NASA's Goddard Space Flight Center in Greenbelt, Maryland, US. "This is the first time that we've been able to watch the sequence with high-resolution spacecraft images," she told New Scientist. Fresh ice Similar transformations happened in the 1980s and early 1990s. Although Hubble was in orbit during the second transformation, its initially flawed vision had not been corrected yet by a space shuttle servicing mission. This time around, the planet has been observed during its transformation not only by Hubble and New Horizons but also at infrared wavelengths by several ground-based telescopes that were also providing context observations for New Horizons. The reasons for the changes are not clear. White clouds are thought to be higher up in the planet's atmosphere than darker clouds and made of fresher ammonia ice. But exactly what gives the lower-altitude brownish clouds their distinctive colour is one of the biggest mysteries about Jupiter. Scientists still do not understand what drives these major shifts in the distribution of these clouds, but the new observations could be the key. "This is the first time that we really have a complete set of data, so we hope that we can use this and figure out what's going on," Miller says. |

Alien hunters 'should also seek weird life'
By Tom Leonard in New York Last Updated: 2:31am BST 10/07/2007 The hunt for extra-terrestrial life should encompass what experts call "weird life", according to a committee of scientists in the US. An artist's impression of the European Space Agency's Huygens spacecraft entering the atmosphere of Titan in 2004. Scientists believe Saturn's largest moon is a promising source of weird life The Huygens spacecraft visited Titan in 2004. Scientists believe the moon is a promising source of weird life Nasa selects planets and moons with hints of water for its exploratory missions. But according to the scientists, who have written a report for the National Research Council in the US, other chemicals such as ammonia or methane could also support life. So-called "weird life" or organisms that lack DNA or other molecules found in life on Earth could exist, the scientists say. For example, while DNA uses phosphorus in its backbone, it might be possible to build a backbone out of arsenic. Titan, one of Saturn’s moons, has been singled out as a particularly promising source of weird life. Michael Meyer, the senior scientist responsible for Nasa’s Mars exploration programme, said: "It’s going to help us a lot to make sure we go exploring with our eyes wide open." "The committee’s investigation makes clear that life is possible in forms different from those on Earth," the scientists conclude in the study, titled The Limits of Organic Life in Planetary Systems. The report also urged that the hunt for weird life be extended to Earth itself, as some examples may exist on the ocean floor, said the scientists. "There’s much about Earth life we don’t understand", said John Baross of the University of Washington, who chaired the committee. |

the amount of water on earth is the same as it has ever been. the amount of fresh water as opposed to salt water is something around 5% of all water on earth is fresh. we pollute it, and we stink it up, but you cannot "use up" water. polluted water evaporates as pure H2O gas, leaving behind all the impurities and pollution. this causes local groundwater to get filthy and not drinkable. it can be reversed. water is constantly recycled. |

once it goes to the ocean its practically gone..... show me desalination process that is environmentally feasable.  |

the line under "cloud formation" and "evaporation" that says "from ocean" would be where I would start looking for clues. |

"The water cycle describes the processes that drive the movement of water throughout the hydrosphere. However, much more water is "in storage" for long periods of time than is actually moving through the cycle. The storehouses for the vast majority of all water on Earth are the oceans. It is estimated that of the 332,500,000 cubic miles (mi3) (1,386,000,000 cubic kilometers (km3)) of the world's water supply, about 321,000,000 mi3 (1,338,000,000 km3) is stored in oceans,or about 95%. It is also estimated that the oceans supply about 90 percent of the evaporated water that goes into the water cycle." |
yeah, that's because there is more water in the ocean than the total volume of fresh water at any given time. thank fuck too, I don't have gills (yet).
it doesn't mean that the evaporation cycle has ceased or that we are experiencing net losses of fresh water due to the oceans. mostly, my comment was about a "desalination process that is environmentally feasable". I found this "funny" (funny strange, not funny haha), since the environment itself is responsible for most of the desalination that occurs on the planet... but nice cut and paste professor! I feel smerter. |
Quote:
who said anything about net loss due to the ocean? I was thinking more like, cities the size of Los Angeles using up to 40% of their available drinking water on their lawns...... |

I had a response typed out about how a desert environment NEVER has enough water (even more so when you stack a zillion people on top of it), but then overwhelming waves of apathy made me delete it. the day that LA cracks off of the continental shelf and sinks below the waves is the day that I begin perpetually tittering like a school girl.

A study into the mysterious changing skull shape of medieval man casts serious doubt on current theories.
The peculiar shift from long narrow heads to those of a rounder shape, and back again, which took place between the 11th and 13th centuries, has been noted at sites throughout western Europe. But a study of skulls found at the deserted village of Wharram Percy, near Malton, North Yorkshire, suggests that the anatomical blip was not down to an influx of Norman immigrants, or climate change, English Heritage has said. It examined nearly 700 skeletons recovered from the village. Unlike other research, data from the Wharram site traces the change to a single, indigenous community which has been radiocarbon-dated. Simon Mays, a skeletal biologist, said: “Our work has yielded few clues on why skulls changed, but we have cast serious doubt on some of the current theories. Despite the best efforts of science, we’re still in the dark to explain why it happened.” The findings are presented in the latest volume of the Wharram Percy project, which aims to publish the results of 40 years of archaeological excavations at the Yorkshire Wolds village between 1950 and 1990. |
A pair of German physicists claim to have broken the speed of light - an achievement that would undermine our entire understanding of space and time.
According to Einstein's special theory of relativity, it would require an infinite amount of energy to propel an object at more than 186,000 miles per second. However, Dr Gunter Nimtz and Dr Alfons Stahlhofen, of the University of Koblenz, say they may have breached a key tenet of that theory. The pair say they have conducted an experiment in which microwave photons - energetic packets of light - travelled "instantaneously" between a pair of prisms that had been moved up to 3ft apart. Being able to travel faster than the speed of light would lead to a wide variety of bizarre consequences. advertisement For instance, an astronaut moving faster than it would theoretically arrive at a destination before leaving. The scientists were investigating a phenomenon called quantum tunnelling, which allows sub-atomic particles to break apparently unbreakable laws. Dr Nimtz told New Scientist magazine: "For the time being, this is the only violation of special relativity that I know of." |

Depleted Uranium Dust - Public Health Disaster For The People Of Iraq and Afghanistan
Dr. Jawad Al-Ali (55), director of the Oncology Center at the largest hospital in Basra, Iraq stated, at a recent conference in Japan: "Two strange phenomena have come about in Basra which I have never seen before. The first is double and triple cancers in one patient. For example, leukemia and cancer of the stomach. We had one patient with 2 cancers - one in his stomach and kidney. Months later, primary cancer was developing in his other kidney--he had three different cancer types. The second is the clustering of cancer in families. We have 58 families here with more than one person affected by cancer. Dr Yasin, a general Surgeon here has two uncles, a sister and cousin affected with cancer. Dr Mazen, another specialist, has six family members suffering from cancer. My wife has nine members of her family with cancer". more at http://www.globalresearch.ca/index.php?context=viewArticle&code=20060503&articl eId=2374 in depth bbc coverage http://news.bbc.co.uk/2/hi/in_depth/...um/default.stm disturbing pictures of deformed babies in Afghanistan http://liberty.hypermart.net/cgi-bin...ade_in_america |
