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]

NP Interview: Federico Grazzini on Climate Change casts shadows on the present and the future of the Mediterranean Basin

Davide Faranda November 17, 2022

Monthly mean sea surface temperature averaged over western and central Mediterranean sea [0E - 22E], months April - November. The blue line corresponds to the recent climatology 1991-2020 with the shading respectively showing 1,2,3 standard deviations of the monthly averages from the mean. Symbols are showing this year values and, for comparison with a previous strongest marine heat wave, the values recorded in 2003.

Weather extreme events in the year 2022 are really hitting the Mediterranean basin very hard. Since the beginning of the year we are observing a widespread drought, heatwaves but also severe thunderstorms. Few days before the COP meeting in Sharm-el-sheik we discussed one of the experts of Mediterranean climate, Federico Grazzini, to unveil whether these events can be linked to climate change.

On October 23 2022, a tornado outbreak occurred in France, causing extensive damages. Tornadoes in France are a relatively rare phenomenon, even more so in the second half of October. This weather phenomenon is linked to intense thunderstorms, and it is difficult to predict because it is very localized. Will global warming make this weather more frequent or intense? A thundercloud that grows visib ...[Read More]

The 2022 European summer was governed by the presence of a persistent cold drop (low pressure area) located between Portugal and France. The change in its position has determined the alternation between hot conditions (low pressure center over Portugal) and stormy conditions (cold drop over France). The warming of the Mediterranean Sea (up to +6°C compared to the period 1990-2020) has largely cont ...[Read More]
