Worrying observations from the Copernicus Climate Change Service. In spite of the cooling impact of the La Nina weather pattern on the tropical Pacific, January 2025 was the hottest month on record. Global temperatures were 1.75 degrees Centigrade above pre-industrial values. Folk should hardly need reminding that the 2015 Paris Accord arbitrarily suggested limiting the rise to 1.5. That's not all! Sea surface temperatures were unusually high in many ocean basins and seas. In deed. January 2025 was the 18th month of the past 19, to record global sea surface temperatures 1.5 degrees Centigrade above pre-industrial levels (https://www.theguardian.com/environment/2025/feb/06/hottest-january-on-record-climate-scientists-global-temperatures-high). The planet's oceans absorb a large percentage of the extra heat produced by the anthropogenic 'greenhouse gas' effect. Higher temperatures, means thermal expansion of the water, raising sea levels. They will also increase the melting of the polar ice caps. This further reduces the reflection of solar radiation back into space. Global heating carries on increasing in what's termed a positive feedback process. Switching this process off, if this is still an option, ain't going to be easy.
