Europa viu la pitjor sequera d’aquests darrers cinc-cents anys, segons que han alertat aquesta setmana experts de la Comissió Europea en un informe. El 47% de la UE és en condicions de risc, és a dir, que les precipitacions han estat inferiors a les habituals i la humitat del sòl és deficitària, i el 17% de la UE és en alerta, és a dir, que també la vegetació i els conreus mostren els efectes negatius de la sequera. De manera acumulada, el 64% d’Europa és en risc o en alerta, cosa que també contribueix a estendre àmpliament les zones de perill d’incendi per tota la UE.
El Servei de Monitoratge de la Terra de Copernicus (CLMS), el sistema d’observació per satèl·lit de la UE i l’Agència Espacial Europea, ha compartit durant l’estiu imatges que mostren els estralls que causa la sequera en diferents parts del món.
Drought in #Italy: the comparison between the #Copernicus #Sentinel2 of #Gardalake coast in August 2021 and 2022 shows the "brand new" beach that appeared this year.

#Drought emergency in Northern #Italy: even the #Piave river is dry.
The impressive #Copernicus #Sentinel2 images of the river in #Veneto (2021 vs 2022) show the difference in dryness and water flow (-25% compared to the historical average).

Portekiz, son 92 yılın en sıcak yaz aylarını yaşarken, Copernicus ve Sentinel2 uyduları tarafından 08 Haziran'da elde edilen görüntülerde bir çok su kaynağını önemli ölçüde kaybettiği görülüyor.

Drought conditions as seen from space thanks to Copernicus Sentinel data. Check out the difference in colors between July 2021 (left image) and July 2022 (right image). A year ago the region was covered by more green foliage, while now the brown areas indicate dry foliage. pic.twitter.com/1PKOS5skpT
