Long term impact

From a draft UN report:

Warming to raise seas for 1,000 years

World sea levels will keep rising for more than 1,000 years even if governments manage to slow a projected surge in temperatures this century blamed on greenhouse gases, a draft U.N. climate report says.

The draft projects more droughts, rains, shrinking Arctic ice and glaciers and rising sea levels to 2100 and cautions that the effects of a build-up of greenhouse gases in the atmosphere will last far longer.

Sea levels rose by 17 cm (6.7 inches) in the 20th century. Rising seas would threaten low-lying Pacific islands, coasts from Bangladesh to Florida and cities from Shanghai to Buenos Aires.

The report says it is "very likely" -- or more than a 90 percent chance -- that human activities, led by burning fossil fuels, are to blame for warming since 1950.

We've been the source of the problem. Are we prepared to be a part of the solution? Are we ready to make the sacrifice? Or are we simply going to pass the consequences of our sins down to future generations?
