The TiPES Podcast - Tipping points change Earth and climate

Huge climate change coming up, if we continue business as usual. The ocean current system, the AMOC, keeps Europe in a relatively mild climate. But the currents show signs of tipping to a dormant sta…

Ice sheets, ocean current systems, and other slowly reacting climate subsystems can be saved after having crossed their tipping points. Paul Ritchie, University of Exeter, on tipping and temperature …

Large, complex climate models previously failed to simulate the frequent, abrupt climate changes of the latest glacial period. However, there is progress in this field. Interview with Louise Sime, Th…

Louise Sime from the British Antarctic Survey explains findings that have indicated the Arctic could be technically free of sea ice most summers within a couple of decades.

Extreme and sudden warmings during the latest ice age might have been controlled by certain amounts of CO2 in the atmosphere. Guido Vettoretti from the University of Copenhagen explains this finding.

Two studies this year involving Niklas Boers of the TiPES-project have found early warning signals for tipping of a large ocean current system in the North Atlantic, called the AMOC and the Greenland…

In this TiPES-podcast, we try to reach an intuitive understanding of climate tipping - not least rate-induced tipping which is when the speed of climate change tilts the system in an irreversible man…

A study in Science indicates that we should reconsider the idea of irreversible abrupt climate change, known as climate tipping. The climate system is more likely to change in smaller steps that migh…

It is important to understand the risk of tipping points under the current climatic situation. To help increase scientific focus on this subject, Thomas Stocker, University of Bern, Switzerland hopes…

The accuracy of climate predictions depends crucially on how the ocean circulation of the North Atlantic is incorporated into climate models, a study shows. Katinka Bellomo, National Research Council…

Deforestation and climate change drive the Amazon rainforest towards tipping points. Niklas Boers from the Potsdam Institute of Climate Change Impact on the mechanisms that threatens the South Americ…

Severe droughts are becoming more frequent in the Amazon rainforest and not only damage the forest but also impact the lives of millions in the area negatively. Niklas Boers from Potsdam Institute fo…

It has long been suspected that the repeated abrupt spikes of heating which took place during the ice ages (Dansgaard-Oeschger events) impacted most parts of the world. Now it has been confirmed by d…

In 2015 Sune Olander Rasmussen from the Niels Bohr Institute was left with a small a few colleagues on the ice sheet of Renland in Eastern Greenland. Their job was to point out the best spot to drill…

We know from the past, that elements in the climate system might pass tipping points after which they enter new states with no return in a foreseeable future. Peter Ditlevsen, the Niels Bohr Institut…

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 Universi…

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…

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…
