Key takeaways include:    📈 Temperatures rose to 1.75ºC above pre-industrial levels  ❄️ Arctic sea ice reached its minimum extent for January  🌧️ Western Europe saw wetter-than-average conditions    🔗 Read the full article on January 2025 climate trends: https://bit.ly/3Cv0NFF   #C3S

Data from #CopernicusAtmosphere and #CopernicusClimate show that in 2024, greenhouse gases reached their highest annual levels ever recorded in the atmosphere. Anthropogenic greenhouse gases have contributed to last year's record-breaking global average temperature and the steady rise in global temperatures over the past decades. 📈 Dive into the Global Climate Highlights report: https://lnkd.in/e6hufCgQ   📉 Explore CAMS' GHG forecasts: https://bit.ly/4gtvRU2

After the series of #wildfires in Los Angeles, a team of ECMWF scientists ask how fire activity can be forecast more accurately than before. They describe a new kind of approach and evaluate how it performed during those wildfires ➡️ https://www.ecmwf.int/en/about/media-centre/science-blog/2025/2025-california-wildfires-insights-ecmwf-forecasts

The January 2025 Hydrology Climate Bulletin from #C3S highlights significant moisture variations globally.    Key insights:  💧 Western Europe, Italy, Scandinavia, and the Baltics saw wetter-than-average conditions, leading to flooding in some areas.  💧 Drier conditions prevailed in northern UK, Ireland, eastern Spain, and north of the Black Sea.  🌍 Globally, Alaska, Canada, Russia, eastern Australia, and other areas experienced above-average precipitation and flooding, while regions like southwestern US, northern Mexico, and northern Africa faced dry spells.

The January 2025 Climate Bulletin produced by #C3S reports ongoing shifts in sea ice dynamics, including a record-breaking low month in the #Artic:   Arctic Insights: ❄️ Monthly average sea ice extent saw the lowest January level in the 47-year satellite record, tied with 2018. ❄️ Sea ice extent was 6% below the 1991–2020 average. ❄️ Well below average anomalies reported in areas like Hudson Bay and the northern Barents Sea.   Antarctic Insights: ❄️ Sea ice extent was 5% below the January average but notably closer to average compared to recent anomalies. ❄️ Above average concentrations in Weddell and Ross-Amundsen Seas, contrasting with below-average areas like the Ross and Bellingshausen Seas and East Antarctica coast.    For a comprehensive analysis, explore the full Climate Bulletin: https://bit.ly/3Q5tWdx #C3S European Centre for Medium-Range Weather Forecasts - ECMWF ECMWF Users Carlo Buontempo

The January 2025 Climate Bulletin is out now, identifying notable trends in temperature, including the warmest January globally on record.  🌡 January global average temperature of 13.23°C, 0.79°C above the 1991-2020 baseline.  🌡 1.75°C above pre-industrial levels – the 18th month in the last nineteen to exceed 1.5°C over pre-industrial levels.  🌍 Europe experienced the second warmest January on record, 2.51°C above the 1991-2020 monthly average, with temperatures significantly above average in southern and eastern regions.  🌊 Average sea surface temperatures over 60°S–60°N were at 20.78°C, the second-highest on record for January.  For more in-depth data and analyses, access the full bulletin here: https://bit.ly/3Q5OuCB #C3S European Centre for Medium-Range Weather Forecasts - ECMWF ECMWF Users Carlo Buontempo

How unusual was the record-breaking global warmth of 2023 and 2024? Both years exceeded the global warming trend, which averages about 0.2°C per decade, while natural fluctuations effects annual global temperatures of up to 0.3°C. Discover the anthropogenic and natural factors contributing to the exceptional temperatures two years in a row: https://lnkd.in/e6hufCgQ     Data highlights: 🌊 Sea-surface temperature anomalies  🌋 Volcanic influence  🚢 Aerosol reduction from decreased shipping  🌞 Solar cycle maximum 💧 Increased water vapour 🔥 Human-induced climate warming

2024 was the warmest year in about one third (32%) of the planet on the dataset record (since 1979), and the warmest year for all continental regions except Australasia and Antarctica. Read the Global Climate Highlights 2024 report: https://lnkd.in/e6hufCgQ  Some of the key findings: 🌍 In 2024, annual surface air temperatures were above the 1991-2020 average across most of the globe (91%). 🌡️ More than half (52%) of land areas saw temperatures exceed the average by more than 1°C. 🍁 As in 2023, northern Canada experienced some of the largest anomalies, with values around 3°C above average. #C3S European Centre for Medium-Range Weather Forecasts - ECMWF ECMWF Users Carlo Buontempo

Map of total Fire Radiative Power from global #wildfires and open burning in January 2025 from the Copernicus Atmosphere Monitoring Service's (CAMS) Global Fire Assimilation System (GFAS) dataset, based on MODIS 🛰 active fire observations (https://lnkd.in/ePSpqGwn). Mostly seasonal tropical fires with some notable hotspots from the devastating southern California fires, western Canada, and both tropical and southern parts of Australia. January 2025 total estimated global fire emissions (& number of fires, fire radiative power, etc) are fairly average in comparison with the January data from 2003 to 2024.
