Climates now in collaboration with cernus hello and welcome to climate now here from Marseilles in the south of France and we’re about to take a deep dive into the Mediterranean to investigate the long-term effects of marine heat waves before we head out to see let’s check the latest data on our warming planet

From the kernus climate change service on a global scale we just had the hottest January on record with temperatur 0.7 de above the 1991 to 2020 average there was a huge contrast in temperatures across Europe in Scandinavia there was a particularly cold spell in early January with temperatures the lowest they’ve been for

Decades in some parts of Lapland meanwhile in Spain people flock to the beach in Barcelona as temperatures soar 8° or more above average towards the end of January across the planet as a whole this map of temperature anomaly shows how the above average temperatures of 2023 continued into

2024 it’s particularly warm over the oceans at the moment data for January indicates the sea surface temperature in non-polar regions is already at least as high as the alltime record set in August last year well now to our story and this region of the Mediterranean has been hit

By heat waves for decades so what impact is that having and can we do anything about it it’s time to load up the boat with diving gear and head out to sea these researchers are measuring the effects of marine heat waves on a long-term basis and they’re setting off to check corals

Close to Mar this picturesque Coastline was hit by Marine Heatwave conditions in 1999 2003 2015 2022 and 2023 marine biologists St and Justine Rish have witnessed how colonies of corals and gorgonians disappeared from the first 10 or 20 meters of water today they’re counting and measuring the colonies in deeper cooler

Zones the video and photos the scientists take offer them a solid base to monitor how Marine heat waves are killing off certain species in the Mediterranean Justine Rishon picks out three photos of the same area near Corsica to illustrate what’s happening for globally the number of marine Heatwave events has doubled since 1982

And species that can’t move like corals the some of the worst affected scientists say the main thing we can do to help them is is to prevent fishing and tourism around vulnerable areas however Marine heat waves are forecast to become more frequent and intense and even in the best conditions

These species grow at just a few millimeters per year well that is all we have time for but you can read a lot more about how our planet is changing on euronews.com climat lamp and I’ll see you next time climate now in collaboration with cernus are
