The TiPES Podcast - Tipping points change Earth and climate artwork

Listen to top scientists on how Earth and climate might change if we hit a tipping point. TiPES is a European science project quantifying tipping points in the Earth system in order to improve climate projections. TiPES is funded by Horizon 2020

Ocean currents will tip mid century

Jul 25 2023 11 mins

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 state already at mid-century. Peter Ditlevsen, the University of Copenhagen.

Undoing climate tipping

May 16 2023 9 mins

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 overshoot.

Will it tip? Large climate models tested on a past climate

Jan 24 2023 11 mins

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, The British Antarctic Survey.

How soon will Arctic sea ice melt away every summer?

Oct 19 2022 14 mins

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.

Were abrupt climate changes during Ice Age controlled by CO?

Sep 05 2022 16 mins

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.

Early warnings for tipping of the West Central Greenland ice sheet and Atlantic ocean currents

Dec 29 2021 19 mins

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 ice sheet. In this TiPES-podcast Niklas Boers explains the findings.

How the speed of change might tip the climate

Nov 22 2021 10 mins

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 manner. Our guest is Professor Peter Ashwin from the University of Exeter, UK. Peter Ashwin was one of the discoverers of rate-induced tipping in 2012.

New study: Tipping might be avoided

Oct 07 2021 13 mins

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 might be reversed if we act quickly enough, the authors argue. Robbin Bastiaansen from the Unversity of Utrecht in The Netherlands explains.

Getting the IPCC to focus more on tipping

Oct 01 2021 10 mins

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 IPCC will reserve a chapter in the next assessment report to tipping points in the Earth system.

Ocean circulation is crucial to the prediction of climate change

Jun 16 2021 12 mins

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 of Italy, Institute of Atmospheric Sciences and Climate explains the findings.
