Tiens, je vais mettre le sujet un peu à jour juste pour t'encourager.

Earth Just Had One of Its Two Warmest Aprils in 141 Years, NOAA Says

April 2020 was among Earth's two warmest Aprils in 141 years of temperature records, continuing a warming trend that could make 2020 the planet's warmest year.

NOAA's April Global State of the Climate Report released Wednesday found global land and ocean temperatures were 1.06 degrees Celsius (1.91 degrees Fahrenheit) above the 20th-century average.

That may not sound impressive, but in the realm of global temperatures, this warm anomaly was second only to 2016 as the planet's warmest April in NOAA records dating to 1880.

Ultimately, what's most important is not whether a given month is a fraction of a degree warmer or colder. Rather, it's the overall trend, which continues its upward climb since the late 1970s.

April 2020 marked the 424th consecutive month and 44th straight April that global temperatures have been above average in NOAA's database.

Parts of northern Asia, including central Russia, were over 4 degrees Celsius (7 degrees Fahrenheit) warmer than average, the highest anomalies over land anywhere on the planet in April 2020.

The Gulf of Mexico was record warm for any April. At just over 3 degrees Fahrenheit above average, it was also the Gulf's highest warm anomaly for any month on record, NOAA wrote.

Adjacent parts of the Caribbean and Mexico were also record warm in April, as were parts of South America, the Atlantic Ocean, Africa, the Indian Ocean and western Pacific Ocean.

NOAA found just under 7 percent of the planet's land and ocean set new April records for warmth.

Much of Canada, the central and eastern U.S. and western Russia were cooler than average in April, according to NOAA's analysis.

Other expert analyses came to a similar conclusion.

NASA's Goddard Institute for Space Studies found April 2020 global average temperatures across all land and ocean surfaces were the warmest on record in their records, which also date to 1880. Temperatures were 0.04 degrees Celsius above the previous record warmest April in 2016.

It was the 11th straight month in the top two warmest respective months in NASA's database, a streak that began in June 2019.

Earlier in the month, Europe's Copernicus Climate Change Service (C3S) also found April 2020 just 0.01 degrees Celsius behind the record-warmest April in 2016.

Will 2020 Become Earth's Warmest Year on Record?

NOAA's report said 2020 was the second-warmest first four months of any year, trailing only 2016.

Parts of Mexico, Central America, the Gulf of Mexico, South America, the Atlantic Ocean, Europe, Asia and the Pacific Ocean had record warmth over the first four months of 2020, according to NOAA.

Given each month this year has been at least the second-warmest respective month, what are the odds 2020 will end up as the hottest year on record?

According to NOAA, 2020 is virtually certain to be at least among the top four warmest years since 1880.

Their calculations also suggest a 69 percent chance 2020 could be the planet's warmest year, eclipsing 2016.

What's particularly impressive about the warm start to 2020 is the lack of warmth provided by an El Niño.

A record-tying strong El Niño lasted through roughly the first half of 2016, giving a boost to global temperatures.

Because much of the increasing heat trapped in Earth's oceans is tucked away at depth, surface air temperatures are generally warming more quickly over land than over water.

Hier, il a fait 130 °F / 54  °C dans la Vallée de la Mort en Californie. Si le record est vraiment confirmé, ça va être la température la plus chaude enregistrée sur la planète depuis 1931.

Death Valley soars to 130 degrees, potentially Earth’s highest temperature since at least 1931

Ça me semble être un peu du Fake News, dans le sens qu'il y a des endroits très chaud sur la planète que ce soit l'Australie, le Mexique, le Moyen Orien et l'Afrique.

Peut-être que c'est le record "enregistré" et que d'autres endroits ont dépassé ça, mais non "officiellement"...

L'article en parlent aussi des autres températures et des records d'ailleurs dans le monde comme au Kébili en Tunisie, au Koweït au Moyen-Orient ou au Pakistan en Asie du Sud.

Par exemple, le dernier record pour l'Afrique date justement de 1931 avec 131 °F à Kébili en Tunisie.
