In another attempt to slow down our fossil fuel based economy, driven by science that is very speculative, the United Nations warns again, that though there is still time to save the world, time is running out; but the key paragraph negating anything the West might agree to do (last one in the excerpt) concerns the polluter nation soon to be the biggest in the world.
Alternative energy is great and much to be desired, but until it actually works and is agreed to be used by all countries, any effort by the United States will only hamstring our economy while autocratic countries who do nothing, outgrow us; which is not a good scenario for global security.
BERLIN — The cost of keeping global warming in check is “relatively modest,” but only if the world acts quickly to reverse the buildup of heat-trapping gases in the atmosphere, the head of the U.N.’s expert panel on climate change said Sunday.
Such gases, mainly CO2 from the burning of fossil fuels, rose on average by 2.2 percent a year in 2000-2010, driven by the use of coal in the power sector, officials said as they launched the Intergovernmental Panel of Climate Change’s report on measures to fight global warming.
Without additional measures to contain emissions, global temperatures will rise about 3 degrees to 4 degrees Celsius (5 degrees to 7 degrees Fahrenheit) by 2100 compared to current levels, the panel said.
“The longer we delay the higher would be the cost,” IPCC chairman Rajendra Pachauri told The Associated Press after the panel’s weeklong session in Berlin. “But despite that, the point I’m making is that even now, the cost is not something that’s going to bring about a major disruption of economic systems. It’s well within our reach.”
The IPCC, an international body assessing climate science, projected that shifting the energy system from fossil fuels to zero- or low-carbon sources including wind and solar power would reduce consumption growth by about 0.06 percentage points per year, adding that that didn’t take into account the economic benefits of reduced climate change. “The loss in consumption is relatively modest,” Pachauri said.
The IPCC said the shift would entail a near-quadrupling of low-carbon energy — which in the panel’s projections included renewable sources as well as nuclear power and fossil fuel-fired plants equipped with technologies to capture some of the emissions….
Counting all emissions since the industrial revolution in the 18th century, the U.S. is the top carbon polluter. China’s current emissions are greater than those of the U.S. and rising quickly. China’s historical emissions are expected to overtake those of the U.S. in the next decade.
