Hommes se baignant dans une rivière, Très riches heures du duc de Berry.

Le mois d'août illustré par une baignade dans la rivière dans les Très Riches Heures du duc de Berry nous rappelle que le Moyen Âge devait aussi s'adapter à la forte chaleur qui pouvait survenir l'été. Arrêtons-nous un instant sur les moyens médiévaux de se préserver de la #canicule ⬇️ 1/14

Climate change is happening. We can see it in our observations. But adaptation to climate change needs to keep up with the weather We keep seeing evidence that our climate is changing rapidly, with more extreme weather causing casualties, damage to infrastructure and businesses, and degradation of our natural environment.

The new Climate Adaptation Research and Innovation Framework (CARIF) describes the research and innovation needed to enable UK adaptation. In our blog, find out how our science informs adaptation advice to government and business to protect the UK from the worst climate change impacts.

🌤️ Connaissez-vous le Cumulus Baguettus ? ☁️

Ce nuage rare, visible par temps clair, ne circule que tout début #avril à l’arrivée du printemps. Sa forme allongée évoque une baguette de pain, d’où son joli surnom ! 🥖

Good to see continued investment in CRU TS. This dataset of gridded observations has been widely used around the world over the last few decades. Its best use is with other environmental datasets, to assess the impacts of climate variability. www.uea.ac.uk/groups-and-c...

Climate services can drive urban resilience—but how do we bridge the "last mile"?

Key lessons:
✅ Start simple: clear, visual insights first.
✅ Integrate adaptation into broader urban planning.
✅ Frame resilience as an opportunity, not just risk.

America, this is what environmental justice is — and what we all stand to lose ​I ran the US Environmental Protection Agency’s environmental justice program for almost 11 years. It’s not what this presidential administration says it is.

This is what environmental justice is - not what you think it is.

This is how it looks in America.

Climate justice is similar, and climate services support it.

This is compassion for those harmed by our environmental destruction, and brave action to defend them.

NOAA launched their Equitable Climate Services Action Plan last spring. www.noaa.gov/news/new-noa...

Often those who suffer most, get least help. NOAA wanted to fix that.

This is about fairness, equality, being human.

The Plan has gone.

Phil is a true public servant. No-one has made a greater contribution to climatology over the last half-century.

He is a great role model for any early career climatologist. Get to know your data, inside-out and back to front. Build something authoritative from it. Keep improving it. Be useful!

How Met Office science is saving Santa’s Christmas journey Met Office scientists apply aviation technology to complete Santa’s Christmas Eve deliveries when his reindeer are stuck by seasonal sniffles.

This is a festive example of a weather service.

A weather service pulls together a forecast and non-weather data (airline priorities). It applies that to a real-world problem (optimal flight path). It delivers the guidance the decision-maker needs.

It is great to see the @metoffice.bsky.social Local Authority Climate Service highlighted in the UK government response to the CCC.

We provide councils with tailored climate data to make evidence-based decisions in their climate adaptation planning: climatedataportal.metoffice.gov.uk/pages/lacs

These maps reveal Australia's potential bushfire future for every postcode As climate change progresses, the CSIRO has created the first detailed national maps to help Australians understand the future risk to their properties.

Maps of wildfire risk in Australia (CSIRO/ABC).

You can see the changing weather hazard for your area under climate change: warmer, drier, windy means more risk.

Other maps in preparation include severity: the intensity of burn.

Great visual from @nick-silkstone.bsky.social on the need for heating.

We expect this to diminish as the climate changes.

Today at the #COP29 event on climate scenarios, #C3S director Carlo Buontempo highlighted that the near real-time production of climate data has attracted new attention and audiences who are asking interesting questions, e.g., about the Honga-Tonga effect, and the reasons for the sharp rise in CH4.🧵

Operationalizing Climate Science There is a need to make climate science more agile and more responsive, and that means moving (some of it) from research to operations.

So - what's going on here, you might ask. This is Farhana's response to a post referring to two natural scientists - a physicist and an earth scientist - who are asking questions about humans - to each other. Farhana suggests (rightly) that these questions would be better put to social scientists 1/

What will the world actually look like at 1.5°C of warming? By the time we hit that temperature, further climate changes will already be locked in and unavoidable.

I wrote this on 1.5°C eight years ago

"Depending on climate sensitivity and natural variability, we could conceivably see the first year above 1.5°C as early as the late 2020s – but it is more likely to be later"

It's looking like I was a bit too optimistic 🧵

Lush grasses provide a living carpet through which the hard lines of the tramway rails pass.

Bordeaux, without any trams to distract from the lush greenery in mid-winter.

Since I haven't seen one yet, here's a starter pack of scientists actively working in the climate adaptation and resilience space, including researchers as well as climate service providers! 🌎🧪

Climate Mapping for Resilience and Adaptation Climate Mapping for Resilience and Adaptation (CMRA) integrates information from across the federal government to help people consider their local exposure to climate-related hazards.

In 2022 the White House and partners launched a climate service to support American adaptation to climate change.

It is called the Climate Mapping for Resilience and Adaptation tool.

It has inspired others, including the UK Local Authority Climate Service.

Have a look!

A graph showing 4 measures of current global warming: (i) the average of the last 10 years (1.2 degrees C); (ii) the average of the last 10 years and a projection of the next 10 years (1.3C); (iii) an estimate using statistical smoothing (also 1.3C); and a calculation of the human contribution to warming (also 1.3C). There are also error bars, the largest being for the human contribution to warming.

In today's update to the WMO State of the Global Climate 2024 report for COP29, we show that the current level of global warming is about 1.3°C

This is important because last year the COP28 text said it was only 1.1°C - but this was based on the 2011-2020 average 🧵

Coppery bracken and a yellow-leaved tree shelter behind a grey-granite wall bordering green fields, all beneath patches of blue.

Colours of #autumn are coming back into the world. The electric blue patches of sky spark off the coppery bracken.

Beneath lowering clouds, a wide strip of blue sky lets through the sunshine onto Dartmoor.

Good news folks! The clouds are rolling back and the sun is breaking through. The stones of Dartmoor are so ancient that apparently they have seen it before :-)

River Teign, Devon, England. At the fringes of a woodland river, stones have been carefully stacked to form the shape of a cross.

Why do we build climate services?

For those of us who are Christians, the answer is...

Love.
