NOAA - National Oceanic and Atmospheric Administration - New Bogus Study Shows Climate Change Largely Irreversible
A new scientific study led by the National Oceanic and Atmospheric Administration reaches a powerful conclusion about the climate change caused by future increases of carbon dioxide: to a large extent, there’s no going back.
The pioneering study, led by NOAA senior scientist Susan Solomon, shows how changes in surface temperature, rainfall, and sea level are largely irreversible for more than 1,000 years after carbon dioxide (CO2) emissions are completely stopped. The findings appear during the week of January 26 in the Proceedings of the National Academy of Sciences.
“Our study convinced us that current choices regarding carbon dioxide emissions will have legacies that will irreversibly change the planet,” said Solomon, who is based at NOAA’s Earth System Research Laboratory in Boulder, Colo.
“It has long been known that some of the carbon dioxide emitted by human activities stays in the atmosphere for thousands of years,” Solomon said. “But the new study advances the understanding of how this affects the climate system.”

If CO2 is allowed to peak at 450-600 parts per million, the results would include persistent decreases in dry-season rainfall that are comparable to the 1930s North American Dust Bowl in zones including southern Europe, northern Africa, southwestern North America, southern Africa and western Australia.

The scientists emphasize that increases in CO2 that occur in this century “lock in” sea level rise that would slowly follow in the next 1,000 years. Considering just the expansion of warming ocean waters—without melting glaciers and polar ice sheets—the authors find that the irreversible global average sea level rise by the year 3000 would be at least 1.3–3.2 feet (0.4–1.0 meter) if CO2 peaks at 600 parts per million, and double that amount if CO2 peaks at 1,000 parts per million.

"An Inconvenient Truth": Dear Al Gore, Have you heard the news? Humans can’t reverse global warming. I know you must feel like a dumb ass now. You should have not believed the hype. Don’t buy any ocean front property…wink…wink. Good Luck with future rantings and maniacal ravings—we all enjoyed the show.
"...southern Europe, northern Africa, southwestern North America, southern Africa and western Australia."
By irreversible they must mean the Sahara, Nabib, Great Sandy, Sonoran, and Mojave, will remain desert no matter what we do.
Ahem, or not.
