Keeping an eye on the regions when it comes to climate change
Up to now, the results of climate simulations have sometimes contradicted the analysis of climate traces from the past. Physicists and climatologists have now brought together experts in climate models and climate tracks to clarify how the discrepancies come about. The surprising result has now been published: in a way, both sides are right. Climate models correctly simulate global temperature trends, but often underestimate the strength of regional climate fluctuations, especially over the course of decades to centuries.

What began as a theory in the 1890s — that industrial emissions of carbon dioxide could increase global temperatures — had progressed to a scientific fact a century later. Scientists across a range of disciplines are studying the impact of the still-growing concentration of carbon dioxide and other so-called “greenhouse gases” in the atmosphere as they call for industrial and governmental policies to slow, then halt, the warming of the planet.
