10 years is just a blink of the ever-watching galactic eye

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.

The South will Rise

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. Two weeks ago two Republican lawmakers, Sen. David Shafer and Rep. Harry Geisinger,proposed that Georgians simply invade their northern neighbor and take their water. Citing a survey from the 1800s, they claim that the state border has crept southward in an incorrect manner and advocate restoring the pre-1818 state lines. The obvious reason for this is the millions of gallons of water in the Tennessee River, one mile north of the present border. "I would offer to settle this dispute over a friendly game of football, but that would be unfair to the State of Georgia,” said Tennessee State Sen. Andy Berke, D-Chattanooga, rubbing salt in the wound inflicted by the Volunteers upon the Bulldogs last year.

Water, water everywh—Oh dear.

So you've all heard about how global warming will lead to rising sea-levels, but what about falling freshwater levels? The New York Times ran an in-depth piece about the disappearing freshwater reserves for the Western United States last week, that being one of the more underreported effects of global warming. With the area's population projected to rise substantially over the next few decades—60 million in California alone by the mid-21st century!—the water demands are going to be a logistical nightmare without even considering a reduced capacity.

The drought went down to Georgia, it was lookin' for some crops to steal...

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.

Green Grass

Record heat. Extreme drought. But the grass must stay green!

California has been delta tough situation

"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.” Long Beach, California has become the first California city to ration water after a court decision last month (SFChron, SacBee) which may require Delta water pumping to be cut by one-third starting in December -- "the single largest court-ordered redirection of water in state history" -- to protect a tiny threatened fish called the delta smelt [resizes window]. (The court decision is not online. An earlier related decision is here.) But the situation is more complex than "drinking water versus fish." Extensive previous efforts have not succeeded in addressing the problems of the Delta, where weak levies were already barely protecting the water supply for 23 million people, a key infrastructure pipeline [pdf], and more and more people's homes [pdf]. (More technical documents here.) Will current efforts be more successful? The many possible solutions each carry their own benefits and controversies. The decision to limit the pumps will certainly draw attention to the issues and give them new urgency. The situation is so complicated, interrelated, and ever-shifting that one artist's Delta primer portrays it as a giant game of chance [pdf].

My Humps, My Humps, My Feral Population Jumps

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.

amazon drought nearing climate tipping point

stbalbach — Tue, 25 Jul 2006 00:05:01 -0800

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".

National Drought Mitigation Center

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]

Countdown to global catastrophe

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.

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. Marine Corps Air Station Miramar has been affected, including an FAA air traffic control installation. 16,000 people in the South Bay lost electricity when a major distribution line went down. Many San Diego firefighters went up to Camp Pendelton yesterday. (1, 2)
