Socio-economic and security implications of global heating

Christian Franzke May 15, 2023

Temperature anomaly for July 2022 with respect to reference period 1959-1989. Data: 2m temperatures from ERA5.

This year, like in the last few years, we are experiencing the effects of global heating in increasingly personal ways. The summer of 2022 exposed us to ever more extreme heat waves in North America, Europe, and Asia. For instance, the heat wave in India and Pakistan reached temperatures of 49C in Nawabshah, Pakistan. North America too experienced devastating heat waves and wildfires. Los Angeles ...[Read More]

Extratropical cyclones play a key role in modulating the precipitation and wind in mid-latitudes and can be responsible for extreme wet and windy events. With global warming, the dynamics and thermodynamics associated with these atmospheric systems are being affected. However, due to the complexity of modelling the climate system, a challenge arises when evaluating the influence that climate chang ...[Read More]

NPG Paper of the Month: “Brief communication: Climate science as a social process – history, climatic determinism, Mertonian norms and post-normality”

Hans von Storch February 16, 2023

The NPG paper of the month for January 2023 was awarded to “Brief communication: Climate science as a social process – history, climatic determinism, Mertonian norms and post-normality” by Hans von Storch. One could argue that climate science is part of geophysics, or more precisely that part of climate science is part of geophysics. But when referring to ”processes” in ”Nonlinear Processes in Geo ...[Read More]

The Great Cold Debate: Is Climate Change to Blame for Extreme Cold Spells?

Davide Faranda December 27, 2022

Average near-surface temperatures showing the extended cold spell over North America on December 24th 2022.

In December 2022, the United States experienced a severe cold spell, with record-low temperatures being recorded in many parts of the country. While it is natural for cold spells to occur, the question has arisen as to whether climate change is playing a role in the intensity and frequency of these events. There is ongoing debate among scientists about the relationship between climate change and ...[Read More]
