Inspired by its 10th anniversary, the Earth Observatory has pulled together a special series of NASA satellite images documenting how the world has changed. From these images, Wired Science has made 5 videos, presenting convenient time-lapse views of the world changing (mainly) because of human actions. Watch the urbanization of Dubai, specifically the growth of Palm Jumeirah. See the Aral Sea dry up - once the fourth largest lake, down to 10 percent of its original size (marked by the thin black line in the video) by 2007. View the clearing the Amazon, as observed from above the state of Rondônia in western Brazil. Behold the return of Mesopotamia's Wetlands, now in the process of being restored from near total destruction under the regime of Saddam Hussein. Witness the impact of drought on Southern Utah's Lake Powell, where water level dropped from 20 million to 8 million acre-feet from 2000 to 2005.

Tennesse and Georgia's war over water There are about five million residents in north Georgia affected by the drought. The phrase "if its brown flush it down, if its yellow let it mellow" has become part of the local jargon in an attempt to encourage water conservation. [more inside]

So you've all heard about how global warming will lead to rising sea-levels, but what about falling freshwater levels? [more inside]

Georgia's going dry -- and we're not talking liquor stores. Record temperatures in Georgia and a long drought have left many Georgia cities wondering when the taps will run dry. Some towns have only a few weeks of water left, while rivers near Athens have nearly dried up. A broken water main hasn't helped the problem, and some fear that the University of Georgia campus there may shut down for lack of water. What's more, Atlanta itself is already feeling the pressure, as Lake Lanier, a water source for 3 million residents, falls by 1.5 feet per week and has only a three month supply remaining. While there have been more severe (pdf) droughts in Georgia's history, rising population numbers have increased demand to now unsustainable levels.

"California has a decision to make. We either brace ourselves for long-term [water] cuts that threaten our economy and our very way of way of life, or we invest in a solution to fix the [San Francisco Bay] Delta and expand our water toolbox so we can meet future challenges head-on.” [more inside]

From far away they came to toil under the scorching Outback sun, and their hardy dispositions and tireless labor helped to create the central Australian railway and telegraph systems. They are the Camels [NPR story w/ audio], and today they are free (well, okay, feral), and they are many (700,000 strong, at least.) While they're no cane toads, they're becoming a bit of a pest. What to do with all those dromedaries? Well, you can race 'em, or you can eat 'em, or maybe you can even try milking 'em. Just get 'em before they get you, mate.

The Amazon rainforest becomes "a desert" after three consecutive years without rain - the trees die. Next year would be the third year of an ongoing drought. The forest contains 90 billion tons of carbon (or about 45 years of stored human emmisions at current rates) - 3/4's of the carbon is released within a year of dieing. The Amazon is "headed in a terrible direction".

Ever think about drought? The National Drought Mitigation Center (NDMC) "helps people and institutions develop and implement measures to reduce societal vulnerability to drought. The NDMC, based at the University of Nebraska-Lincoln, stresses preparation and risk management rather than crisis management." Lots of interesting things in here, like the drought maps that stretch back to 1895, and the Standardized Precipitation Index Maps. You can also check the Drought Monitor to see how dry things are as of last Thursday. [via the excellent j-walk blog]

Global warming approaching point of no return...
Climate change: report warns point of no return may be reached in 10 years, leading to droughts, agricultural failure and water shortages. The possibilities include reaching climatic tipping points leading, for example, to the loss of the West Antarctic and Greenland ice sheets (which, between them, could raise sea level more than 10 metres over the space of a few centuries), the shutdown of the thermohaline ocean circulation (and, with it, the Gulf Stream), and the transformation of the planet's forests and soils from a net sink of carbon to a net source of carbon. Countdown to global catastrophe

Santa Ana Speeds the Spread of So Cal Fires
Five separate fires are burning in San Diego County, including several densely populated suburban areas. Dozens of homes have been burned.
