Ancient pine trees growing in eastern Spain have quietly recorded more than five centuries of Mediterranean weather. Analysis of tree rings clearly shows that todays storms and droughts are becoming more intense and more frequent than almost anything the region has experienced since the early 1500s.

In 2025, 50% of the globe experienced more days than average of at least strong heat stress – with “feels-like” temperatures of 32°C or higher. 🔥 At the same time, most regions saw fewer cold stress days than average.

Challenges in global climate models to represent cloud response to aerosols: insights from volcanic eruptions - Nature Communications This study uses a multi-model intercomparison framework and a large-scale observational constraint based on a volcanic eruption and shows that climate models strongly underestimate how cloud cover res...

New study uses a global observational constraint based on a #volcanic eruption and shows that #ClimateModels strongly underestimate how #cloud cover responds to #aerosols, leading to major uncertainties in climate projections. www.nature.com/articles/s41...

Regional map of average energy imbalance during 2020-2024 relative to 2001-2019.

All changes in Earth's temperature are connected to changes in Earth's energy imbalance, i.e the difference between energy absorbed from the sun and energy radiated into space.

Recently, net increases have been largest in the Southern Ocean, Atlantic, North Pacfiic, and Europe.

Global water security threatened by rising inequality - Nature Geoscience By 2100, 62% of the global population could face severe water scarcity, with inequality amplifying risk. Equitable management offers a path to water security, according to a machine learning forecasti...

Marcus Lacerda, o infectologista brasileiro que foi perseguido por liderar o estudo que comprovou a ineficácia da cloroquina no tratamento da Covid-19, foi nomeado diretor do TDR, uma das plataformas mais estratégicas da Organização Mundial da Saúde (OMS).

Which option do we choose - act or delay?

These are the 'warning' stripes highlighting global choices. Do we act rapidly and keep global temperatures below 2°C, or delay and end up in a 3°C world (or worse)?

Bar graph showing US temperatures by year. Blue bars going down are temperatures below 20th century average and are present in beginning of graph 1895-1970s. Orange bars most recently indicate above-average temperatures. Temperatures are rising because of climate change.

📈 It's official from NOAA. 2025 was the fourth-hottest year on record (since 1895) for the contiguous U.S. 🔥

Average temperatures for the contiguous U.S. in 2025 were 2.6°F (1.4°C) warmer than the 20th century (1901-2000) average.

Line graph time series of CO2 equivalent mixing ratio (in ppm) from 1700 through 2024 for AGGI, CO2 alone, and CO2 plus non-CO2 GHGs. There is a long-term increasing trend in recent years only.

Looks like this data was quietly updated in the fall for the latest numbers through 2024 - Annual Greenhouse Gas Index (AGGI) produced by NOAA...

It is now up to a 54% increase in the influence of greenhouse gases in the atmosphere since 1990 (AGGI = 1.54; heat trapping)

Green line graph time series of average sea surface temperature anomalies for each January-November from 1850 through 2025 for only the midlatitude region of the North Pacific Ocean. There is large interannual variability, but an overall long-term increasing trend. Anomalies are computed relative to a 1981-2010 baseline. 2025 is a record high.

Check out this year's extreme sea surface temperatures and recent warming across the North Pacific... 🌊

This graph shows the average for a band across the midlatitudes for every average January-November period from 1854-2025 using ERSSTv5 data.

Systematic attribution of heatwaves to the emissions of carbon majors - Nature Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

A paper published in Nature in September suggests a quarter of heatwave events from 2000-23 would have been near impossible without anthropogenic climate change. The paper also indicates that major carbon emitters are responsible for around 50% of the increase in intensity of these events. ⚒️ 🧪
