The temperatures of this last week of April are totally exceptional. Although it would be more 'normal' to see them in July and August, even there they would fall within the high range for the season. That is, they would be typical for a very hot summer day. If the forecasts are fulfilled, we expect to break temperature records in many capitals. And not by tenths, but by a long way. An intense and extensive heat that will also move after sunset, with tropical nights expected in different municipalities. It should be emphasized that this episode is attributed to an exceptionally warm air mass for the season, and not to local and orographic effects that are sometimes capable of triggering temperatures in certain areas. Hence its extent and intensity.
It is important to speak clearly about this type of episodes. This is climate change. Of course, a subsequent attribution study will have to be carried out to see how much it is linked to global warming, but undoubtedly, without anthropogenic forcing, we would be talking about much more moderate values.
This, which is now something strange, which is news, will unfortunately cease to be so in a few years. Because we will get used to it, because having happened before, it will not be talked about.
Everything that is happening is consistent with climate change projections, as was the case last summer and as will be the increased frequency of these extreme events in the future.
