Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi were awarded the prize for their independent, groundbreaking research that provides the basis for current climate models and helped sound an early alarm on human-caused climate change. Klaus Hasselmann created a model that links together weather and climate. His methods have been used to prove that the increased temperature in the atmosphere is due to human emissions of carbon dioxide. Great review article appears at Science.org. Check out our Research Labs web page where research on climate modeling and CO2 is actively been pursued by world renowned scientists.
