Average person will be 40% poorer if world warms by 4C, new research shows (theguardian.com)
Economic models have systematically underestimated how global heating will affect people’s wealth, according to a new study that finds 4C warming will make the average person 40% poorer – an almost four-fold increase on some estimates.

State of the Global Climate 2024 (wmo.int)
The clear signs of human-induced climate change reached new heights in 2024, which 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.

Plants losing appetite for carbon dioxide amid effects of warming climate (theguardian.com)
Our planet is losing its appetite for mopping up carbon dioxide. Analysis of atmospheric carbon dioxide measurements show that Earth’s plants and soils reached peak carbon dioxide sequestration in 2008 and absorption has been declining ever since. Passing this tipping point increases the chances of runaway climate breakdown.

Record January heat: La Niña may be losing its ability to check global warming (theconversation.com)
January 2025 was the hottest on record – a whole 1.7°C above pre-industrial levels. If many climate-watchers expected the world to cool slightly this year thanks to the natural “La Niña” phenomena, the climate itself didn’t seem to get the memo. In fact, January 2025’s record heat highlights how human-driven ocean warming is increasingly overwhelming these natural climate patterns.

Twelve months at 1.5 °C signals earlier than expected breach of Paris Agreement (nature.com)
June 2024 was the twelfth month in a row with global mean surface temperatures at least 1.5 °C above pre-industrial conditions, but it is not clear if this implies a failure to meet the Paris Agreement goal of limiting long-term warming below this threshold.

An Arctic 'beyond recognition' by 2100 (colorado.edu)
In 2024, annual average global air temperatures surpassed 1.5 degrees Celsius above pre-industrial levels for the first time, triggering extreme weather events like record-breaking rainfall and flooding events in the Sahara Desert and extreme summer heat waves across the planet. However, global warming will not stop at this level.

Global Climate Highlights 2024 (copernicus.eu)
2024 saw unprecedented global temperatures, following on from the remarkable warmth of 2023. It also became the first year with an average temperature clearly exceeding 1.5°C above the pre-industrial level – a threshold set by the Paris Agreement to significantly reduce the risks and impacts of climate change. Multiple global records were broken, for greenhouse gas levels, and for both air temperature and sea surface temperature, contributing to extreme events, including floods, heatwaves and wildfires.

Fiji is already relocating villages because of climate change (zmescience.com)
Climate migration is no longer a distant fear — it’s a reality. In Fiji, it’s a particularly pressing reality. Rising seas and extreme weather have forced entire communities to move. For this Pacific island nation, the question isn’t whether to relocate people but how to do so in a way that protects lives and livelihoods. Meanwhile, the rest of the world is watching closely as one billion people may find themselves in a similar situation in a matter of decades.
