00:00 I don't want to die! I can't die! I need to go now!
00:04 Between the fires in Greece, with the evacuated populations and even the crash of a Canadair,
00:09 the deadly fires in Algeria or the chaos in Italy,
00:12 Oh my god, my god, my god, my god, my god, my mom, my mom, my mom!
00:16 this summer, extreme climatic events are multiplying in the whole northern hemisphere.
00:20 Our tour of the horizon in images to measure the extent of the problem.
00:23 After a first fifteen records, the month of July 2023 may be the hottest ever recorded on Earth,
00:28 according to the estimates of the European observatory Copernicus.
00:32 The heat wave that is currently striking the United States, for example,
00:35 affects a very large part of the population.
00:37 90 million Americans have suffered temperatures above 41 degrees
00:41 over the weekend of July 22 and 23,
00:44 or more than a quarter of the country's inhabitants.
00:46 The situation is particularly extreme in Phoenix, Arizona.
00:50 Temperatures above 43 degrees were frequently recorded there
00:54 throughout the month of July,
00:55 to the point that the bitumen caused burns at 3 degrees to inhabitants who had fallen to the ground.
01:01 In the Mediterranean, The Guardian lists no less than nine different countries in the heat of the flames.
01:05 In Greece, the fires hit the Attic, the Peloponnese, the island of Rhodes,
01:09 or the island of Bé, where the crash of a Canadair cost the lives of two pilots on July 25.
01:16 In Algeria, at least 34 people died in the fires
01:19 that hit the mountainous region of Kabylie in the east of the country.
01:23 Fires are also to be deplored in France, Portugal or Croatia.
01:27 And in Italy, the situation is particularly critical.
01:30 The press describes a country cut in half by a "crazy climate".
01:34 In the south of the country, especially in Sicily,
01:37 temperatures are close to 45 degrees and dangerous fires are on the way.
01:41 The airport in Catan even had to close for five days because of the fires.
01:45 And in the north, violent storms hit Milan and neighboring cities.
01:48 They caused tree falls and floods.
01:51 In these images, we can see the city of Serenio in Lombardy,
01:54 flooded by frozen waters after a hail fall.
01:58 But this list is far from exhaustive and could go on for a long time.
02:02 And these extreme events, recorded in July 2023 in North America,
02:06 Europe or China, could not have occurred without global warming.
02:10 This is what a study published on July 25 by the World Weather Attribution,
02:14 an international consortium of climate-related scientists, shows.
02:18 They explain that without the climate change caused by man,
02:21 these heat waves would have been extremely rare.
02:24 In China, they would have occurred only once in 250 years.
02:27 While in the United States, Mexico and southern Europe,
02:30 the record heat of July 2023 would have been almost impossible
02:34 if humans had not heated the planet by consuming fossil fuels.
02:39 Yet these hazards are deadly.
02:40 In Europe, it is estimated that in 2022,
02:42 more than 61,000 people will die from summer heat.
