Reduction in probability for snow on Christmas due to climate change:
If we simply compare the period 1951–1980 through 1995–2024, it looks like this. 👇

In some places in Central and Eastern Europe, the number of white Christmases have decreased with 50 percentage points. ❌❄️

Surprisingly little coverage of the 10th anniversary of the Paris Agreement, tbh. The undisputed high watermark for multilateralism and a belief in a better future, as well as the primary mechanism for averting civilisation-scale disaster, and the milestone is still passing largely without comment.

Kombinationen av dåligt ledarskap och klimatförändring bäddar för katastrof på många håll. Tråd om storstäder med vattenbrist:
Varför är det här inte en större nyhet och varningsklocka? Är vi redan så avtrubbade, i början av en eskalerande klimatkatastrof?

"Situationen är så allvarlig att Irans president Masoud Pezeshkian varnat för att staden kan bli obeboelig och behöva flyttas om ingenting förändras."

Another warm year
We now expect 2025 annual temperatures to more or less tie 2023 as the second warmest year on record in ERA5, at around 1.48C relative to preindustrial (1850-1900).

However, other surface temperature datasets (e.g. Berkeley Earth) may show a tad lower as the third warmest.

The Trump-Putin petro-oligarch alliance
Extraordinary WSJ reporting today that unveils the extent to which Trump, Witkoff, Kushner and US business executives are salivating over business deals with Russia while Putin’s forces kidnap Ukranian children and bomb civilians in their apartments.

It’s especially ironic because the lecture is exactly about the ‘paralyzing cowardice’ of today’s elites.

About universities, corporations and media networks bending the knee to authoritarianism. /4

El Niño is over but the heat is still here
This continued warmth means that it is likely that 2025 will end up more or less tying 2023 as the second or third warmest year since records began in 1850.

'All systems are flashing red': How the world is failing in its climate goals
The latest State of Climate Action report reveals that for all the progress sparked by the clean tech boom, the global economy is still badly off track for meeting its net zero goals

Koldioxidhalten i atmosfären ökar snabbare än väntat. Har nu nått över gränsen för 1,5-graders målet
Yes the CO2 rise 2023-2024 was faster than we predicted at Mauna Loa and was a record rise there - now the WMO confirm the global mean rise was also a record

Also the rate of CO2 rise is now above the IPCC scenarios that limit global warming to 1.5C

This is either clever or crazy or both: a UK company will install, in your home, a miniature data center, about the size of a heat pump, to serve as your home heating.

Jag vill minnas att regeringen sa att det inte var något problem med minskad reduktionsplikt eftersom de skulle satsa på elektrifieringen av fordonsflottan
Det går inget vidare.

“It took Denmark approximately 30 months to go from a 20% share of electric cars to 60%, while this period took longer for Norway.”

Trafikverket har nu bestämt sig. Efter skarpa direktiv från regeringen har de landat i hur mycket pengar av 1 200 miljarder som ska gå till det mest hållbara trafikslaget cykel. Och summan är noll (0) kronor.
Så mycket pengar satsas på cykel i nya infraplanen

Another consequence of US budget cuts on climate change research - less science from Antarctica

NEW: China's president Xi Jinping unexpectedly joins the UN climate summit, by video, to offer his nation's 2035 climate pledge

* Cut GHGs to 7-10% below peak by 2035, "striving to do better"
* Raise non-fossil share of energy to at least 30%
* Boost wind/solar to 3,600GW

Låg ambitionsnivå i Kinas nya klimatmål som presenterades i FN igår:
Xi Jinping announced China's new climate targets personally, a positive gesture, but the targets brought little clarity on China’s future emission pathway. Targeting a 7-10% emission reduction by 2035 from an undefined "peak level" undersells China's current clean energy boom.

När den statlig byråkratin - som bör verka apolitisk och endast utgå från lagen - underställs auktoritära krafter kommer kapitalistiska företag vara de första som kastar överbord värdegrund och dylikt i syfte att få igenom sina önskemål - det är i princip inbyggt i den ekonomiska rationalismen.

Here are 10 provocations on climate and energy. Tell me if you agree, disagree or have a nuanced take. Drop your own provocations in reply or quote post.

Start:

1. By 2030, the use of air conditioning will lead to greater increase in electricity demand than data centers. And it's not even close!
