New Zealand’s climate policy is no longer sufficient to limit warming to 1.5°C. what needs to happen
Credit: NASA/Earth Observatory, CC BY-SA It’s now official. Last year was the warmest year on record globally, and the first to exceed pre-industrial temperatures by 1.5 degrees Celsius. This does not mean it is too late to limit further warming, but each delay in action increases the ambition needed. New Zealand is no exception. Current climate policies are no longer…

Climate researchers discover that clouds have a surprising effect on surface warming
DLR decomposition changes in SGP. Credit: Nature (2025). DOI: 10.1038/s41586-024-08323-x Researchers at McGill University have found that changes in clouds are slightly mitigating global warming. While temperatures continue to rise due to greenhouse gases, the amount of heat trapped near the surface has slightly decreased due to less low-lying cloud cover over land. “We started this study to observationally test…

2024 will be the hottest year on Earth as global warming trends continue
Credit: Unsplash/CC0 Public Domain The Earth experienced its warmest year on record in 2024, according to data from the European Union’s Copernicus Climate Change Service, a European-led environmental monitoring program. The service said last year it exceeded the limit of 1.5°C (2.7°F) above the pre-industrial average set by the 2015 Paris Agreement, an international agreement aimed at reducing and reducing…

Models suggest snowmelt from Greenland and the Arctic is weakening ocean circulation and accelerating warming southward.
The addition of melt water to the North Atlantic causes local cooling in the subpolar North Atlantic and warming in the South Atlantic. Credit: Nature Geoscience (2024). DOI: 10.1038/s41561-024-01568-1 The vast network of ocean currents known as the “global ocean conveyor belt” is slowing down. This is a problem because this critical system redistributes heat around the world, influencing both…

Humans are already causing long-term global warming of 1.5°C, according to new estimates
Credit: Pixabay/CC0 Public Domain New research published today in Nature Geoscience by Dr Andrew Jarvis of Lancaster University and Professor Piers Forster of the University of Leeds shows that humans have already contributed to global warming of 1.5°C, measured since the period just before the industrial revolution and the 2000s. This indicates that it may be causing the The beginning…

Planting trees in high Arctic latitudes could accelerate rather than slow global warming, scientists say
Direct and indirect effects of afforestation on climate forcing at high latitudes and their relative magnitude over the life of the plantation. a, Plantation establishment disrupts previously intact soils and increases microbial carbon decomposition (1). This is exacerbated by enhanced soil insulation caused by increased snow entrapment and decreased snow cover (2). Growing trees exude carbon from their roots, accelerating…

Valencia floods: warming climate is making once rare weather more common and more destructive, researchers say
In recent days, a seasonal weather system known in Spain as a “cold drop” or DANA (an acronym for “depresión aislada en niveles altos”: isolated cyclone at high level) has been causing heavy rain and flooding across Spain’s Mediterranean coast. causing flooding in Andalusia, especially in the Valencia region, Castile-La Mancha and the Balearic Islands. The storm left hundreds of…

Study provides refined estimates of permafrost loss in Alpine Asia due to future warming
The permafrost on the Qinghai-Tibetan Plateau is thawing, leading to recession. Credit: Jie Jiang Permafrost on the Qinghai-Tibet Plateau has thawed. Credit: Jiang Jie Climate models are important for predicting future changes caused by greenhouse gas emissions and can guide policy decisions regarding climate mitigation. However, some of the latest climate models, particularly the latest generation set, are considered “too…

Global warming is happening, but it’s not statistically ‘spiking’, new study finds
Example of GMST time series with spurious fit. Credit: Communications Earth & Environmental (2024). DOI: 10.1038/s43247-024-01711-1 With record heatwaves occurring around the world in recent years, an international research team including statisticians from Lancaster University found that the rate of global warming has increased significantly, or “suddenly”, over the past half-century. We investigated whether Statistically detectable proportion. The new study,…

DOI: 10.1038/s41467-024-50813-z What will the future climate look like? Scientists around the world are bringing together Earth system models and large observational datasets to study climate change in hopes of understanding Earth’s climate and predicting the climate for the next 100 years. But which models…
