Scientists used the NCAR climate system model to track how global air and ocean circulation could evolve at increasing levels of CO2.
Rocky Mountain Climate
The study suggested that the Great Plains, the Rocky Mountains and the Southwest are stricken by the same “mega-drought” when for multiple years the tropical Pacific turns cold at the same time that the North Atlantic warms.
Surface and atmospheric temperatures have risen in western Canada since the middle of the 19th century.
The projected sea-level rise is due to a revised estimate of the ice melt from glaciers.
Researchers assessed a body of long-term data including temperatures, sea ice and ocean structure, snow and glacier cover, and atmospheric circulation.
