Klaus Hassel

Klaus Hasselmann is a renowned climate scientist and physicist who, along with others, developed methods to identify and analyze how human activities influence climate change. His work uses complex climate models and statistical techniques to distinguish natural climate variability from human-induced effects. This has been crucial in understanding how greenhouse gases affect global temperatures and weather patterns. Hasselmann's contributions have profoundly advanced climate science, leading to more accurate predictions and informing international climate policy. In 2021, he was awarded the Nobel Prize in Physics for his pioneering research connecting climate variability with human activities.
