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.

Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain.
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.

The world's frozen oceans, which help to keep the planet cool, currently have less ice than ever previously recorded, satellite data shows.
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.
It's 'Virtually Certain' the World Has Breached 1.5C (bloomberg.com)
The world may have already missed its chance to limit global warming to 1.5C, according to two new studies in Nature Climate Change.
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.
Hottest January on record mystifies climate scientists (theguardian.com)
A run of record-breaking global temperatures has continued, even with a La Niña weather pattern cooling the tropical Pacific.
Climate change target of 2C is 'dead', says renowned climate scientist (theguardian.com)
The pace of global heating has been significantly underestimated, according to renowned climate scientist Prof James Hansen, who said the international 2C target is “dead”.

Earth breaches 1.5 °C climate limit for the first time: what does it mean? (nature.com)
It’s official: Earth’s average temperature climbed to more than 1.5 °C above pre-industrial levels for the first time in 2024.
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.

The planet has moved a major step closer to warming more than 1.5C, new data shows, despite world leaders vowing a decade ago they would try to avoid this.
Even NASA Can't Explain the Alarming Surge in Global Heat We're Seeing (sciencealert.com)
The world has been getting hotter for decades but a sudden and extraordinary surge in heat has sent the climate deeper into uncharted territory – and scientists are still trying to figure out why.

2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees Celsius above the preindustrial level, another record.
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.
Meltwater from Greenland and the Arctic is weakening ocean circulation (theconversation.com)
A vast network of ocean currents nicknamed the “great global ocean conveyor belt” is slowing down. That’s a problem because this vital system redistributes heat around the world, influencing both temperatures and rainfall.
