Around 1900, he proposed the influential climate classification system which now bears his name alongside his collaborator, Rudolf Geiger.

ABSTRACT: We used the Köppen-Trewartha classification on the CMIP5 family of global climate model (GCM) simulations and global Climatic Research Unit (CRU) data for comparison. This evaluation ...

A new study evaluating models of future climate scenarios has led to the creation of the new risk categories “catastrophic” and “unknown” to characterize the range of threats posed by rapid global ...

The KÖppen climate classification system was first published in 1918 by German climatologist Wladimir KÖppen, but the system has been updated several times, including changes by American ...

A study has divided the world into 12 climate zones on the basis of the Köppen–Geiger classification map. The paper confirmed Chile’s Atacama region has the world’s highest solar radiation ...

The Köppen climate classification system was first published in 1918 by German climatologist Wladimir Köppen. Faced with a lack of adequate observing stations, Köppen used vegetation to ...

A new study evaluating models of future climate scenarios has led to the creation of the new risk categories “catastrophic” and “unknown” to characterize the range of threats posed by rapid global ...

For some countries, climate change has already pushed most of their territory into a different climate zone. Our research shows what’s already happened – and what’s yet to come.

New climate risk classification created to account for potential 'existential' threats Researchers identify a one-in-20 chance of temperature increase causing catastrophic damage or worse by 2050 ...
