La vague de chaleur qui accable l'Europe depuis plusieurs jours aurait été "quasiment impossible" il y a 50 ans et le changement climatique en est "incontestablement" la cause, affirme le World Weather Attribution (WWA) dans une analyse "rapide" publiée vendredi.

Het KMI start het project 'Tales of Future Weather', dat klimaatwetenschap omzet naar concrete scenario’s van extreem weer zoals hitte, droogte en hevige neerslag. Zo worden de gevolgen van klimaatverandering tastbaar en kunnen we ons beter voorbereiden. Het project benadrukt dat burgers zelfredzamer moeten worden. "Er komt heel wat op ons af."

A climate monster is growing right now in the Pacific Ocean, perhaps the most fearsome El Niño since before scientists even began modeling them. They now know the pattern quite well: A marine heat-wave in the Pacific Ocean scrambles global weather and produces in some places more intense droughts and in others more intense rainfall and flooding; disruptions to hurricane patterns and monsoon seasons, which can cause widespread crop failures; and much more punishing heat.

The European Center for Medium Range Weather Forecasts (ECMWF) earlier this year issued a forecast of a strong (“Super”) El Nino to begin later this year and peak in early 2027, as we have discussed in two earlier posts.3,4 El Ninos are important because of the large effects that they have on global weather, even though those effects are not always consistent from one El Nino to another. El Ninos have even greater effect in combination with ongoing global warming, e.g., Radfar et al.5 find that the combination of an El Nino with increasingly prevalent marine heat waves results in tropical cyclones consistently producing higher maximum wind speeds, storm surges, and precipitation rates, and Liu et al.6 describe evidence of El Ninos strengthened control over global climate anomalies in a warmer world

El Niño could fuel extreme weather and raise temperatures to record highs this year, but how sure can we be that it will return?

The world endured its costliest wildfire on record in 2025, its sixth-deadliest heat wave, and four floods or storms that caused at least 1,000 deaths.

I always say that models are not predictions; they are qualitative illustrations of what the future could be. But as the future gets closer to the present, models can start being seen as predictive tools. It is the weather/climate dichotomy, so aptly exploited to confuse matters by politically minded people in the discussion about climate. Right now, we are getting close to the point that we could forecast a collapse in the same way as we can forecast the trajectory of a tropical storm. So, you remember how “The Limits to Growth” generated a long term forecast in 1972. Here it is

A “pushing and triggering” mechanism has has driven the Arctic climate system to a new state, which will likely see consistently increased frequency and intensity of extreme events across the atmosphere, ocean and cryosphere this century.

De door de mens veroorzaakte klimaatverandering maakte de droogte die Zuid-Europa dit voorjaar trof 10 keer waarschijnlijker. Dat besluiten klimaatwetenschappers van het collectief World Weather Attribution. Die droogte leidde tot verwoestende zomerbranden in onder andere Turkije, Griekenland en Cyprus. Als de klimaatverandering zich verder doorzet, dreigen zulke megabranden nog veel alledaagser te worden dan ze vandaag al zijn.

Extreme heat is breaking records around the world, with wildfires and poor air quality compounding the crisis, according to a report from the World Meteorological Organization (WMO) released Thursday.

Extreme heat ‘the new normal’, says UN chief, as authorities across the continent issue health warnings

New data from Nasa has revealed a dramatic rise in the intensity of weather events such as droughts and floods over the past five years.The steepness of the rise was not foreseen. The researchers say they are amazed and alarmed by the latest figures from the watchful eye of Nasa’s Grace satellite, which tracks environmental changes in the planet.

Breaching threshold would ramp up catastrophic weather events, further increasing human suffering

Selon une alerte du réseau scientifique World Weather Attribution (WWA), ce mercredi 11 mai, cette fonte accélérée serait le résultat d’une vague de chaleur record entre le 15 et le 21 mai, qui a aussi touché l’Islande.

The Earth had its second-warmest April in NOAA's 176-year period of record. The 10 warmest Aprils on record have occurred since 2010.
