We're Already Topping Dust Bowl Temperatures -- Imagine What'll Happen if We Fail to Stop 10°F Warming
Continued from previous page
- NOAA: Climate change “largely irreversible for 1000 years,” with permanent Dust Bowls in Southwest and around the globe. This January 2009 PNAS paper finds
… the climate change that is taking place because of increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop…. Among illustrative irreversible impacts that should be expected if atmospheric carbon dioxide concentrations increase from current levels near 385 parts per million by volume (ppmv) to a peak of 450-600 ppmv over the coming century are irreversible dry-season rainfall reductions in several regions comparable to those of the “dust bowl” era
- Michael Wehner et al., “ Projections of Future Drought in the Continental United States and Mexico” (2011). A good PDF of a PowerPoint presentation ia here.
The ‘debate’ about the future of drought in the United States under business-as-usual emissions, such as it is, is how far into the northern US Great Plains and Midwest Dust Bowl conditions will extend — and that’s without even considering the impact of the increasingly early loss of the winter snowpack, which most of these studies don’t even model.
Are we really so blinkered that we we are going to take the risk ruining the breadbasket of the world just as we are adding another 2 billion people to the planet?
