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]

Can Artificial Intelligence replace scientists to explain Climate Change? Find it out in our first interview to… ChatGPT!

Davide Faranda January 3, 2023

Figure: DallE (the visual cousin of ChatGPT) has produced this image when I asked for “a cartoon showing a climatologist with research articles walking on a weather map” As a communication officer of the division of Nonlinear Processes I started to write posts for the EGU blog a few years ago and I found it a very difficult task: one has to find the right scientific sources about arguments ...[Read More]

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

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]
