Il est très probable que l'année 2024 enregistre des températures sans précédent, alors que l'année écoulée a marqué la fin d'une décennie de chaleur record, mettant la planète "au bord du gouffre", a averti l'ONU mardi.

00:00 "It is very likely that 2024 will record unprecedented temperatures, while the year
00:05 that has passed has marked the end of a decade of record heat, putting the planet on the
00:08 brink of a gulf," warned the UN on Tuesday.
00:11 A new report from the World Meteorological Organization (WOM), an UN agency, shows that
00:17 records were broken last year, even in some cases pulverized, regarding
00:21 greenhouse gas levels, surface temperatures, thermal content, absorbed and stored energy
00:27 and ocean acidification, sea level rise, the expansion of the Antarctic basin
00:33 and the receding glaciers.
00:34 "We cannot say with certainty, but I would say that there is a high probability that
00:39 2024 will once again break the record of 2023," Omar Badour, of the WOM, said in a press conference.
00:45 "The planet is on the brink of a gulf, while pollution from fossil fuels causes
00:50 unprecedented climate chaos," warned UN Secretary-General António Guterres in a
00:55 video message, while estimating that "it is still time to launch a rescue
01:00 buoy for the population and the planet."
01:02 "Each fraction of global warming has an impact on the future of life on Earth,"
01:07 warned the UN chief.
01:09 Red Alert.
01:10 "The climate crisis is the determining challenge that humanity is faced with and
01:14 it is inextricably linked to the crisis of inequalities, as evidenced by growing food insecurity,
01:20 population displacement and biodiversity loss," said Secretary-General of the WOM.
01:25 Celeste Solo.
01:26 "Heat waves, floods, droughts, uncontrolled fires and the rapid intensification of tropical
01:33 cyclones are causing misery and chaos, disrupting the daily lives of millions of people and
01:38 inflicting economic losses of several billion dollars," warned the WOM.
01:42 It is also the hottest decade, 2014 to 2023, ever observed, exceeding an average of 1.20
01:50 degrees Celsius.
01:52 The rise in global temperature over the long term is due to the increase in greenhouse
01:58 gas concentrations in the atmosphere, which reached record levels in 2022.
02:02 The arrival of the El Nino phenomenon in the middle of 2023 also contributed to the rapid
02:07 rise in temperatures, according to the WOM.
02:10 According to Madame Solo, "we have never been so close, although temporarily for the
02:14 moment, to the lower limit set at 1.5 degrees Celsius in the Paris Agreement on Climate
02:19 Change."
02:20 The World Meteorological Community warns the world and rings the alarm bell, "we
02:25 are on red alert," she said.
02:27 Oceans and glaciers.
02:29 Last year, nearly a third of all oceans in the world were engulfed by a wave of
02:34 marine heat.
02:35 By the end of 2023, more than 90% of the planet's oceans had experienced heat waves
02:41 at one time or another of the year, according to the WOM.
02:44 The increase in frequency and intensity of marine heat waves is causing profound
02:49 negative repercussions on marine ecosystems and coral reefs.
02:52 In addition, the average sea level on a global scale reached a record level in 2023, which
02:58 translates into the continuation of ocean warming, thermal expansion, as well as the melting
03:02 of glaciers and glacial slopes.
