Socio-economic and security implications of global heating
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]

Off-shore wind energy plays a key role in the transition to a renewable energy (RE) system, and its usage is expected to increase in the next few decades. Nevertheless, wind energy is one of the most variable and weather-dependent RE, because of its natural dependence on the wind speed, which can vary at different time scales, ranging from small-scale turbulence to seasonal oscillations and up to ...[Read More]

Over 70% of the Earth’s surface is covered by seas and oceans but in the geological past the extension of sea and land has varied several times as sea level changed over time. During the past millions of years, the oceans have cyclically retreated and expanded with the alternating of warmer and colder climatic periods in consequence of the astronomical motions of the Earth, repeatedly changi ...[Read More]

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

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]
