Can Art Make (Climate) Models Better?

Screenshot from Future Models Manual website

by Felix Schaumann

How do we think about climate futures ahead of us? Different actors tend to use different tools for that. The stream of weather catastrophes in the news media suggests a rather gloomy future. Some recent novels try to paint a more optimistic picture of the decades ahead (see our post on this).

International climate politics, for its part, has mainly based visions of the future on IPCC scenarios and model projections. For example, integrated assessment models (IAMs) played an important role in highlighting the feasibility of limiting global warming to 2 or even 1.5 degrees, and thereby led the way to the Paris Agreement. At the same time, this policy ambition came at the expense of modelling huge quantities of negative emission technologies, which again had a strong influence on the climate policy discourse.

Clearly, model-based climate futures are important for climate politics, but it is far from obvious what goes into them and based on which premises they are devised. Lisette van Beek tried to shine some light on fundamental questions about IAMs by teaming up with artists Ekaterina Volkova and Julien Thomas and writing an IAM manual.

Why Don’t We Act Now? The discrepancy between climate change awareness and action

By Marina Falke

The 6th IPCC Report of Working Group 3 was published just about two months ago, on April 4, and stated once more and in further detail the urgency to mitigate climate change. As known, the Intergovernmental Panel on Climate Change (IPCC) consists of politicians and scientist of the United Nation, grouped in three working groups focusing on different aspects of climate change. The third working group specializes in climate change mitigation and presents sources of global emissions as well as developments in emission reduction and mitigation efforts. Despite the great importance of the report’s findings, neither sufficient media coverage nor meaningful political reaction have yet materialized. Why is the gap between climate change’s urgency and action on it still so wide? Continue reading Why Don’t We Act Now? The discrepancy between climate change awareness and action

Warum das Zwei-Grad-Ziel ein (Kommunikations-) Problem ist

von Michael Brüggemann und Fenja De Silva-Schmidt

Thermometer 2 Grad mehrIn seinem Kommentar zur Klimapolitik hat sich der Innenpolitik-Chef der FAZ kürzlich schwer vertippt: Er schreibt, es gäbe „die Verpflichtung, bis 2050 die Erwärmung deutlich unter zwei Grad zu senken“. Dabei ist es natürlich so, dass sich die Zwei-Grad-Grenze, so wie sie die Staatengemeinschaft 2015 in Paris beschlossen hat, auf das Jahr 2100 bezieht. Fehler können passieren und gehören zum journalistischen wie zu jedem anderen Handwerk dazu – genauso wie eine öffentliche Korrektur des Fehlers, mit Publikation möglichst an gleicher Stelle.

Dass ein solcher Fehler bei einer der führenden Qualitätszeitungen vorkommt, hat aber möglicherweise tieferliegende Gründe: Die Zwei-Grad-Grenze bietet keine Anleitung und wenig Anreiz für gute Klimapolitik in der Gegenwart.

Tag 1 des K3 Klimakongresses

von Joana Kollert

Mit 500 TeilnehmerInnen eröffnete am 24. September 2019 der K3 Klimakongress in Karlsruhe. Ohne Zweifel ist die Klimakommunikation ein Thema, welches viele verschiedene AkteurInnen betrifft. Die Organisatoren des K3 Kongresses können es also als Erfolg verbuchen, eine sehr bunte Mischung an AkteurInnen angelockt zu haben: 29% stammen aus der Wissenschaft, 19% aus der Politik & Verwaltung, 16% aus der Zivilgesellschaft, 13% aus den Medien, 9% aus der Wirtschaft und 9% aus dem Bereich Ausbildung/Studium (Quelle: S. Trümper, DKK).

Lost on the Road to Paris? The Framing of a 2 degree warming limit 2009-2014

Blog by Prof. Markus Rhomberg

As the climate negotiations in Paris near their final rounds, some might be surprised by rather contradictory developments, which relate to the much discussed 2 degree threshold.

This limit aims to keep warming within 2°C of the pre-industrial average.While the emissions reduction pledges put forward by the countries ahead of COP 21 in Paris were not sufficiently ambitious to keep within this limit, in the final phase of the negotiations many countries wish for an even lower limit: below 1.5 degrees.

Was the “failure” of the Copenhagen climate summit key to expected “success” in Paris?


Blog by Professor Hans von Storch

Professor Hans von Storch is a highly distinguished ocean and climate scientist. He has written 20 books and sits on numerous climate advisory boards. He usually writes for the climate blog: Die Klimazwiebel

Recently, a journalist asked me in passing – which was the best COP so far, which the worst?

Honestly, I have not been a good observer of these meetings. All I know there were many and the next is #21. There was Copenhagen, sometimes labelled Hopenhagen by enthusiasts. It was COP15 and the year was 2009. Copenhagen, the last exit, it was called, the last chance for instituting a binding policy which would make “us” limit global anthropogenic (human-caused) climate change to a stable 2 deg in 2100.

Paris rises after attacks while some pacific islands are going under

Blog by Elisabeth Eide

The Paris climate protests on Sunday 30 November were largely silent. After the 13 November terror attacks and the state of emergency introduced by President Hollande, demonstrations are banned.

At Place de la République, where the monument is still surrounded by messages of grief and the scent of roses, activists gathered in the morning. Several thousand pairs of shoes were placed to draw attention to the ban on demonstrations. A few hours later, some people tried to march, but were stopped by a massive contingent of police who barred all the roads exiting the place.
