State of the Southern Ocean 2024

Record heat, warming seas, shifting salinity & summer chlorophyll spikes: the SOOS-led Southern Ocean chapter in this year's @ametsoc State of the Climate highlights how the SO is reshaping global climate. ➡️https://ametsoc.net/sotc2024/06Antarctica_SotC2024.pdf

The latest climate data is conclusive and alarming: 2024 set new records for increased temperature, rising sea levels and glacial melting.

The State of the Climate in 2024: 2024 was the hottest year in records dating back to the mid-1800s, beating out 2023, and "[t]he last 10 years (2015–24) are now the warmest 10 in the instrumental record." #climatecrisis #savetheplanet #climateactionnow ametsoc.net/sotc2024/Sot...

The State of the Climate in 2024: "The annual sea surface temperature was the highest in the 171-year record, marking the second year in a row that the global ocean set such a record." #climatecrisis #savetheplanet #climateactionnow ametsoc.net/sotc2024/Sot...

The State of the Climate in 2024: Atmospheric concentrations of the major planet-warming gases – CO2, methane, and nitrous oxide – hit new highs. CO2 is now 52% above preindustrial levels. #climatecrisis #savetheplanet #climateactionnow ametsoc.net/sotc2024/Sot...

The State of the Climate in 2024: "The global average number of high humid heat days ... over land reached a record of 35.6 days more than normal in 2024, surpassing the previous record set in 2023 by 9.5 days." #climatecrisis #savetheplanet #climateactionnow ametsoc.net/sotc2024/Sot...
