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]

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]

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]
