More than 150 ‘unprecedented’ #climatedisasters struck world in #2024 - #UN
#Floods, #heatwaves and supercharged #hurricanes occurred in hottest #climate human society has ever experienced
#WMO's report on 2024, hottest year on record. Heatwaves in Japan left hundreds of thousands of people struck down by heatstroke. Soaring temps during heatwaves peaked at 49.9C at Carnarvon in Western Australia, 49.7C in city of Tabas in Iran, and 48.5C in nationwide heatwave in Mali.

The Guardian · More than 150 ‘unprecedented’ climate disasters struck world in 2024, says UNBy Damian Carrington

« The devastating impacts of the climate crisis reached new heights in 2024, with scores of unprecedented heatwaves, floods and storms across the globe, according to the UN’s World Meteorological Organization. […] The world is already deep into the climate crisis, with the WMO report saying that for the first time, the 10 hottest years on record all occurred in the last decade. However, global carbon emissions have continued to rise, which will bring even worse impacts. […] Dr Davide Faranda, from ClimaMeter, said: “Every fraction of a degree matters. The choices we make today will determine the severity of climate impacts in the years to come.” » theguardian.com/environment/20

"The #WMO’s report on 2024, the hottest year on record, sets out a trail of destruction from #ExtremeWeather that took lives, demolished buildings and ravaged vital crops. More than 800,000 people were displaced and made homeless, the highest yearly number since records began in 2008.

The report lists 151 unprecedented extreme weather events in 2024, meaning they were worse than any ever recorded in the region. "

🌡️ 2024 was the warmest year on record at approximately 1.55°C above the pre-industrial (1850-1900) average

🌅 Each of the past eight years has set a new record for ocean heat content

🧊 The three lowest Antarctic ice extents were in the past three years

🏔️ The largest three-year loss of glacier mass on record occurred in the past three years

🌊 The rate of sea level rise has doubled since satellite measurements began

☁️ CO2-concentration is at the highest levels in the last 800,000 years

#WMO report

"The clear signs of human-induced #ClimateChange reached new heights in 2024, with some of the consequences being irreversible over hundreds if not thousands of years, according to a new report from the World Meteorological Organization (WMO), which also underlined the massive economic and social upheavals from #ExtremeWeather.

Laut einem Bericht der #WMO erreichte der menschengemachte #Klimawandel 2024 einen neuen Höhepunkt!
👉 t1p.de/fb4bl
Die wichtigsten Aussagen:
- Wichtige Klimawandel-Indikatoren erreichen neue Rekordwerte
- Anstieg des Meeresspiegels und Erwärmung der Ozeane für Jahrhunderte unumkehrbar
- Rekordtreibhausgaskonzentrationen in Kombination mit u. a. El Niño führen zu Rekordhitze 2024
- Frühwarnungen und Klimadienste sind unerlässlich

WMO’s State of the Global Climate report confirmed that 2024 was likely the first calendar year to be more than 1.5°C above the pre-industrial era, with a global mean near-surface temperature of 1.55 ± 0.13 °C above the 1850-1900 average. This is the warmest year in the 175-year observational record.

WMO’s flagship report showed that:

Atmospheric concentration of carbon dioxide are at the highest levels in the last 800,000 years.
Globally each of the past ten years were individually the ten warmest years on record.
Each of the past eight years has set a new record for ocean heat content.
The 18 lowest Arctic sea-ice extents on record were all in the past 18 years.
The three lowest Antarctic ice extents were in the past three years.
The largest three-year loss of glacier mass on record occurred in the past three years.
The rate of sea level rise has doubled since satellite measurements began.

January sets an unexpected temperature record

Both 2023 and 2024 were exceptionally warm years, at just below and above 1.5C relative to preindustrial in the #WMO composite of surface temperature records, respectively. While we are still working to assess the full set of drivers of this warmth, it is clear that a sizable portion of 2024’s elevated temperatures were driven by a moderately strong El Niño event that peaked in November 2023.
January 2025 beat the prior record set in January 2024 by a sizable margin. And unlike the prior record Januaries (2007, 2016, 2020, and 2024) there is currently no #ElNiño event boosting global temperatures; rather, the world is in modest #LaNiña conditions that should, all things being equal, result in lower global temperatures.

So what does this mean? Thankfully #weather models expect global temperatures are set to drop next week as the Northern Hemisphere sharply cools, making it less likely that February will also set a new record. But an unexpected record to start things off may presage higher temperatures this year than many of us thought.
