The TiPES Podcast - Tipping points change Earth and climate
New study: Tipping might be avoided

New study: Tipping might be avoided

October 7, 2021

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.

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.

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.

We know, that climate tipping could lead to abrupt climate changes. It now turns out, tipping might take place before we would expect it to - due to rate-induced tipping. Johannes Lohmann from Physics of Ice, Climate, and Earth, The Niels Bohr Institute, the University of Copenhagen, Denmark.

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 American rainforest.

Droughts in the Amazon rainforest can now be predicted

Droughts in the Amazon rainforest can now be predicted

October 30, 2020

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 for Climate Impact Research explains how it is now possible to forecast these droughts up to 18 months in advance.

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 data. Sune Olander Rasmussen from the NIels Bohr Institute explains the finding, published today in Science.

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 ice which could be used for calibrating temperatures in other ice samples.

The urgency of understanding tipping points

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 Institute speaks on the importance of the TiPES project.

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.
