These are the new models. The prediction goes to 2099. The prediction doesn't change the question. How long is Earth habitable?

BOULDER (click here) —The United States and many other heavily populated countries face a growing threat of severe and prolonged drought in coming decades, according to a new study by National Center for Atmospheric Research (NCAR) scientist Aiguo Dai. The detailed analysis concludes that warming temperatures associated with climate change will likely create increasingly dry soil conditions across much of the globe in the next 30 years, possibly reaching a scale in some regions by the end of the century that has rarely if ever been observed in modern times.

Using an ensemble of 22 computer climate models and a comprehensive index of drought conditions, as well as analyses of previously published studies, the paper finds much of the Western Hemisphere, along with large parts of Eurasia and Africa, may be at threat of extreme drought this century.
In contrast, higher-latitude regions from Alaska to Scandinavia are likely to become more moist.

Dai cautioned that the findings are based on the best current projections of greenhouse gas emissions. What actually happens in coming decades will depend on many factors, including actual future emissions of greenhouse gases as well as natural climate cycles such as El Niño.

The new findings appear this week as part of a longer review article in Wiley Interdisciplinary Reviews: Climate Change. The study was supported by the National Science Foundation, NCAR’s sponsor....

The National Center for Atmospheric Research (NCAR) was designed by a small group of innovative scientists, most of them university faculty members, as a creative response to major challenge that faced the nation in the years between the 1930s and late 1950s. Departments of Meteorology had been established at the Massachusetts Institute of Technology, the University of Chicago, and other U.S. universities in the 1930s. Their goal was to investigate scientifically the physical principles that were thought to define the behavior of the atmosphere.

The University Corporation for Atmospheric Research (UCAR) (click here) is a consortium of more than 100 member colleges and universities focused on research and training in the atmospheric and related Earth system sciences. Our members set directions and priorities for the National Center for Atmospheric Research, which UCAR manages with sponsorship by the National Science Foundation. Through our community programs, UCAR supports and extends the capabilities of our academic consortium.
