Climate change – problem and action

Posted on 06. Oct, 2010 by crowley in Blog, General, Renewable Energy News

A couple of recent news stories of note… First, news (here in Science News, but widely reported in mainstream media) that the earth’s hydrological cycle is accelerating rapidly due to warmer temperatures.

A new study finds evidence that global warming has been speeding up this hydrological cycle recently, a change that could lead to more violent storms. It could also alter where precipitation falls — drying temperate areas, those places where most people now live.

The impact as precipitation shifts away from more densely populated areas to the poles and tropics is one concern, but so is the rise of ocean levels, long predicted, now measured.

Among the new study’s more dramatic calculations: River runoff into the seas has been increasing by some 540 cubic kilometers per year, or about 1.5 percent annually over the period analyzed (1994 to 2006).

A second story actually gives rise to some hope on this front, reporting the progress made by the Canadian province of Ontario to wean itself off of coal-generated electricity.

“The province has added more than 8,000 MW of new, cleaner energy since 2003.

Government figures show that since 2003, when coal-fired electricity use peaked, Ontario Power Generation’s emissions of sulphur dioxide and nitrogen oxides are down 81% and 77%, respectively. The coal plants’ carbon dioxide emissions are down 71% from 2003, according to the government estimates.”


It can be done… we simply need the will to do it.
