Climate: Are you ready for the heat?

U.S. temps expected to climb 9 degrees by 2100

All around the globe, the land areas show a greater increase in temperature than the surrounding ocean waters. Evaporation of the water helps to keep the ocean surface cool and the deep depths of the ocean have a large capacity to absorb energy before heating up.

FRISCO — After last week’s release of a relatively short summary of global warming science, the Intergovernmental Panel on Climate Change has now published a full report detailing the science. The report is available at the IPCC website.

It not easy reading, and it’s not easy to swallow the conclusions, but the report makes it clear that this is not the time for denial. The most pronounced warming will be in the northerh hemisphere, and areas like the Rocky Mountains and northern Canada could feel the heat sooner rather than later.

Without drastic cuts in greenhouse gas emissions, the average temperature across the contiguous 48 states is projected to increase by a life-changing 9 degrees Fahrenheit by 2100. Globally, temperatures are expected to climb by 7 degrees.

That warmth will cause sea level to rise by anywhere from 10 to 35 inches by 2100 — and that’s a conservative estimate. Some other studies estimate a 40-inch rise in sea level by 2100.

One crucial area that isn’t comprehensively covered by the IPCC involves the carbon locked into the world’s icy permafrost region. The report estimates huge thawing in permafrost region, but downplays the additional warming effects resulting from the release of that carbon, which could amount to another couple of degrees of temperature increases by 2100.

  1. The problem is, those with expertise have no power, and those with power have no expertise.

    Greed will always blind, and governments are easily swayed by blind power.

    Governments are voted in by the people to govern “for” the people, not “for” big business.
