Thirty years ago summer in Sardinia lasted less . This year we fell asleep slipping more and more into the humid “tropical nights” which are not characterized only by strong heat but by the fact that temperatures remain unchanged compared to daytime ones.
The climate is changing and the new dimensions of the planet must lead us to find adaptation solutions for citizens and businesses.
The topic was addressed in Cagliari at a conference held by Medsea , the Foundation created on the initiative of a group of researchers determined to protect the management of the marine resources of Sardinia and the Mediterranean.
Since 1951 - the year in which the Elmas Air Force station came into operation - the average temperature in Cagliari has increased by two and a half degrees to today . The tropical nights that in the sixties and seventies were in all twenty have become more than fifty .
“Once the Azores anticyclone was able to mitigate the summer heat, now that phenomenon is relegated to the Atlantic and we are increasingly at the mercy of the African anticyclone”, explained Matteo Tidili , meteorologist of Rai Meteo.
Unfortunately , temperatures alter all cycles , starting with that of water. According to Tidili, the rains on the Mediterranean could drop by forty percent in winter, a bad sign because the water on earth goes away in some parts but concentrates on others, in the form of real bombs that cause floods; rain and drought will continue to alternate as the concentration of greenhouse gases and methane increases by raising the thermometer.
