What to do about global warming?

From Alternet:

Examining 24 major ecosystems that support human life, scientists found that 15 are "being pushed beyond their sustainable limits," toward a change that will be "abrupt and potentially irreversible." Humanity's genius at economic development has taxed our ecosystems to the point where we face "imminent ecological and economic crises."

Economically, the world is booming. Steel, aluminum, vehicle production and Gross World Product set records in 2005, as did Internet usage and cell phones. Unfortunately, the production of atmospheric CO2 concentrations, the main greenhouse gas, is also booming -- 2004 measured the highest annual increase ever. Average temperatures in 2005 were the hottest ever recorded on the earth's surface, the warmest in 10,000 years.

Warming has led to the destruction of 20 percent of the world's coral reefs and 25 percent of the world's mangrove forests. Sea ice fell to the lowest levels ever recorded and almost a third of the Arctic Ocean, normally covered by ice in the summer, has melted. Weather-related disasters, attributed to global warming, reached a record cost of $204 billion, with record hurricane, forest fire and tornado seasons in the US.

Global warming is here and scientists predict that the number and severity of weather-caused disasters will increase as the earth warms through the heat trapping effects of greenhouse gases created by burning oil, coal and natural gas, which accounts for 80 percent of the world's energy use. With the US consuming roughly a quarter of the world's oil and, along with automobile exhaust, creating almost a quarter of the world's greenhouse gases, pressure is mounting to switch to alternative sources of fuel to modify the amount of damage created by global warming in the future.
