Heatwaves contribute to the warmest June on record in western Europe The European continent experienced two significant heatwaves in mid-June and late June-early July 2025. The first event peaked between 17 and 22 June, affecting large parts of western and southern Eur...

Daily sea surface temperature anomalies (°C) averaged over the western Mediterranean basin from 1979 to 30 June 2025. The year 2025 is highlighted in dark red and 2023 in light red. All other years are shown in grey. The western Mediterranean domain (1°W–15°E, 33–46°N) used to compute the time series is shown in the map above. Data source: ERA5. Credit: C3S/ECMWF.

Anomalies and extremes in the average surface air temperature between 17 June and 2 July 2025. The extreme categories (‘coolest’ and ‘warmest’) are based on rankings of average temperatures for the same 16 days during 1979–2024. The other categories describe how the temperatures compare to the distribution of these temperatures during the 1991–2020 reference period. ‘Much cooler/warmer than average’ - cooler/warmer than 90% of temperatures. ‘Cooler/warmer than average’ - than 66% of temperatures. ‘Near average’ - within the middle 33%.

🌡️ June 2025 was the 3rd warmest June globally

🥵 June 2025 saw an exceptional #heatwave impact large parts of western Europe

🌊 This heatwave was made more intense by record ocean temperatures.

#climate change means heatwaves are:
🌞more frequent,
📈 more intense &
🌍 impact more people

Oh - I didn’t know about this one! 🙌

Is it hot right now? YES!! (In most of Europe anyway) 🥵🥵🥵

Shocking and 💔 proposal to destroy so much expertise and scientific knowledge built up over decades

Science saves lives! 🧪🌎⚒️

Surprisingly, extremely hot (for Austral winter) in some West Australian locations

Is it hot right now? Is it hot right now, or does it just feel like it?

The tongue of Rhone #Glacier ten days after my last visit. Can you guess how much ice melted away? 1️⃣ meter in terms of thickness! 1️⃣0️⃣ days... And that's just the beginning of the summer season.
We know the times are bad for the ice, but still it is hard to accept these numbers!

Could you clarify the 0 degree isotherm height and data source? Is it higher than the +5000 m in September 2023? Thanks in advance!

Thanks Leon, unfortunately I’ve not taken a closeup of the embroidery, clearly I need to!

Happy summer/winter #solstice and #showyourstripes day

Presenting the @edhawkins.org #climate and #ocean stripes at #UNOC3 in Nice. Dress embroidery highlighting biodiversity loss in a warming, acidifying, over-exploited ocean 🌊🧪⚒️🌏🌡️

I usually say that 1.5°C or 2°C of warming is not a threshold, but a TARGET to stay under.

Here, Ben Santer and colleagues warn that future climate change will be larger than in recent decades, and our near-term choices will decide if we cross the THRESHOLD of dangerous anthropogenic interference.

Climate futures: World leaders’ failure to act is pushing Earth past 1.5°C This story is the first article of a two-part Mongabay mini-series exploring possible climate futures. Part Two will be published soon. The last two years brought record-shattering temperatures global...

Is our planet losing resilience? Rates of warming in both the atmosphere and the ocean are increasing 🌊🌡️🌍🧪⚒️

#UNOC3 #ClimateAction

Beautiful morning in Nice for #UNOC3 looking forward to connecting with many colleagues and the @copernicusmarine.bsky.social session today on the importance of ocean monitoring for #SDG14 and #climateaction

May 2025 breaks an unprecedented long sequence of months over 1.5ºC above pre-industrial

🌡️ May 2025 was the second warmest May globally

📈 May 2025 was 1.40°C above the estimated 1850-1900 average

🌊 SSTs were the 2nd highest on record for May, with an extreme marine heatwave in the North Atlantic

Wherever you live in the world, your climate is getting warmer.

21st June is #ShowYourStripes day when we encourage everyone to use the warming stripes graphics to talk about climate change and how we are all already experiencing the consequences.

Important: if you think that governments should move faster on climate, enacting policies now for a cleaner, greener future, *** you are in the MAJORITY ***. A huge majority.

HT to @tomheap.bsky.social for digging out this Nature paper on who actually wants what.

Weakened Atlantic Meridional Overturning Circulation causes the historical North Atlantic Warming Hole - Communications Earth & Environment The North Atlantic Warming Hole is tied to a weakened Atlantic Meridional Overturning Circulation during the past century, according to climate models and observation data.

New study confirms that the famous 'cold blob' or 'warming hole' observed in the northern Atlantic is caused by a weakening Atlantic overturning circulation. 🌊

Folks, fractals are everywhere, and they are inspiration for your work. They demonstrate the power of small, how little details make up something vast and complex. You are part of a dynamic system and you matter. Keep going!
