Today @copernicusecmwf.bsky.social and @wmo-global.bsky.social launch the European state of the climate Report 2024 👇 Thank you to the amazing editorial team and all those who contributed!

Copernicus ECMWF@copernicusecmwf.bsky.social · last yr.

The #ESOTC2024 report is out! Explore the contrasts across Europe, from the dry and often record-warm conditions in the east to warm but wet conditions in the west. #ESOTC2024 is a joint effort between #CopernicusClimate and @wmo-global.bsky.social, together with over 100 scientists. bit.ly/3G9MdEX

New post on The Climate Brink from Zeke @hausfath.bsky.social about our climate future. With current policies, we’re on track for a bit less than 3C, with 2030 NDCs we’re on track for about 2.5C, and with net zero pledges we’re on track for a bit less than 2C. www.theclimatebrink.com/p/moving-awa...

Moving away from high-end emissions scenarios

I have a new commentary in Dialogues on Climate Change exploring climate outcomes in current policy scenarios

From aming all the great charts that came out on Jan10 on 2024's climate, I like this one among the most. It shows nicely how the past two years have stood out not only from.the warming trend, but even from the extreme outliers from the warming trend. 2023-2024 were extreme among the extremes.

"every fraction of a degree matters" is true as hell. In the same way that releasing CO2 hurts people and planet, avoiding its release saves us from potential harm This isn't some saccharine 'hopeful' message: it's the hard, inarguable physical reality. www.ipcc.ch/report/ar6/w...

With all the news about the latest data showing that temperatures in 2024 were 1.6°C warmer than pre-industrial levels, many have asked what this means for the 1.5°C of the UN Paris Agreement. A short 🧵that aims to distinguish the signal from the noise (1)

The data is in. 2024 was the warmest year on record, and probably in the whole of human history – about 1.6°C warmer than the pre-industrial period. More than 1 billion individual thermometer measurements, made by thousands of people over many decades, have been condensed into a single number.

Warming stripes for 1850-2024, changing from blues to reds as the world rapidly warms up

Looking ahead to 2025, we expect it to be slightly cooler than 2023 and 2024 at around 1.4C above preindustrial levels, as El Nino has faded away and cooler conditions are developing in the tropical Pacific.

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold. We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940. 2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.

Ridgeline chart showing the distribution of global daily air temperature differences from the pre-industrial reference period (1850-1900), for every year between 1940 and 2024. Each individual year resembles a hill, shaded in a darker shade of red and further to the right for warmer years. The trend is clearly towards warmer years, with 2024 standing out as first year above 1.5C.

Amazing how eating less meat is better for people, animals and planet. Processed red meat contributes to dementia AND cancer, heart disease, diabetes, air+water pollution, climate warming methane emissions and even #birdflu ALL of which translate to more overall illness and healthcare cost.

#PlanetaryHealth and #Brain and #MentalHealth "People...who ate at least two servings per week of processed red meat (such as bacon, bologna or hot dogs) had a 14% increased risk of #dementia, compared to those who ate less... after the 43-year follow-up period." www.nbcnews.com/health/aging...
