Tipping Sahara from desert to green and back

April 30, 2020

Sahara turned green at the end of the last ice age. Climate sciencists have struggled to model exactly how the transition took place. Professor Paul Valdes from Physical Geography at Bristol University, Great Brittain explains how a detailed understanding is now within reach.

We narrowly missed an ice age 100 years ago

We narrowly missed an ice age 100 years ago

Earth was very close to entering an ice age only 100 years ago due to natural causes. Now we must wait at least 100.000 years for the next ice age. This is shown by work of Andrey Ganopolski from PIK Potsdam. (13 min.)

How much will a doubling of CO2 change Earth temperatures?

How much will a doubling of CO2 change Earth temperatures?

How much will temperatures go up, if we double the amount of CO2 in the atmosphere? That has turned out to be a tricky question to answer scientifically. In this podcast, climate scientist Anna von der Heydt explains how initial conditions turn out to be important for getting the right answer: When the Earth system is in a cold state it does not react to a doubling as it does in a warm state. Which state are we in now, then?

Understanding data from the climate system is like trying to find the melodies in the cacophonic noise of an uncoordinated orchestra- but this is what mathematician and climate scientist Michael Ghil has been working on for decades, improving the equations we use for predicting future climate.

Climate change is abstract and hard to understand. Rain, drought, storms and flooding make much more sense to the human mind. That is why climate scientist Susanna Corti is working on predicting changes in the future local weather patterns of Europe.
