Kai Kornhuber is a Senior Scientist and leader of the Group Climate Extremes and Climate Modelling at Climate Analytics. He is also an adjunct Associate Research Scientist at the Lamont-Doherty Earth Observatory, Lecturer at the Columbia Climate School in New York and a Senior Fellow on Climate Risks at the German Council on Foreign Relations.
His research is dedicated to physical drivers of extreme weather and climate events and associated societal impacts under current and future climatic conditions.
He is Founding Member of the EarthNetwork on Sustainable and Resilient Living in an Era of Increasing Disasters at Columbia’s Climate School, Co-Chair of the Compound Events Working Group at Risk-Kan and a Co-Pi of the Project PERSEVERE within the BMBF Consortium ClimXtreme. At Climate Analytics he is leading the efforts on quantifying Physical and Acute Risks within the NGFS network.

- Boreal summer weather becomes more persistent in a warmer world
El Niño is contributing to the hottest temperatures ever recorded – what does this mean for the Paris Agreement’s 1.5°C limit?
Extreme weather is raging across the northern hemisphere. Our experts explain the implications of the emerging El Niño for our changing climate.
Climate models underestimate food security risk from ‘compound’ extreme weather
Climate change poses a risk to global food security. Weather and climate extremes, such as prolonged drought, heavy rainfall and heatwaves, can lead to harvest failures. These are occurring with increased magnitude and frequency on a warming planet. In addition, such events can disrupt supply chains, decreasing food supply and leading to price spikes.
Hot, dry or flooded — more weather extremes beyond 1.5°C warming
This blog gives an overview of the most important recent studies on climate impacts and extreme events. Much of it will be synthesised in the IPCC special report on 1.5˚C, due out in October, which will be a key document for setting the course of climate policy at a global level.
