📣 We just released a new free resource at @climatecentral.org - a 72-slide deck introducing key facts about climate change, including its causes, impacts, and solutions. It also comes with speaker notes and links for local storytelling.

We have put out some new NDC snapshots. Check them out: www.climate-resource.com/tools/ndcs?v.... The latest is the Chinese NDC that sets an emissions reduction of 7–10% below the peak by 2035, moving from a carbon intensity goal to an absolute target. This enhances transparency and accountability.

Simon Holmes à Court pays $15,000 to put climate scientist on ‘mystery flight’ with Sussan Ley

Climate 200 founder beats out at least six other bidders for meeting with opposition leader in charity auction for Parliament’s Midwinter Ball * Get our breaking news email, free app or daily news podcast Climate 200 founder Simon Holmes à Court has paid $15,000 to secure a mystery flight with Sussan Ley – and put a climate scientist and a young climate organiser on the plane – winning a charity auction at Parliament’s Midwinter Ball. The flight, and lunch with the opposition leader at a country pub, was offered in the auction organised by the Canberra press gallery for the annual event. Continue reading...

Yes, it is painful. And it would be less painful if there were good options of how Tesla drivers could be a pain to Elon.

My attempts to start a discussion about that were banned in 'Tesla owners' facebook forums. Those have remarkable membership numbers (75k in Australia). You know what to do.

Malte Meinshausen @meinshausen.bsky.social · Jan 21

Maybe one can replace "to drive a Tesla" with:
- to not be ashamed driving one
- to not have a bumper sticker expressing that
- to not pledge never to buy one again
- .. etc.

Just asking for a friend .

A new paper led by Sebastian Sippel just appeared in Nature arguing that ocean temperature measurements in the early 20th century have a cold bias.

It's a fun story illustrating the process of scientific discovery, so let me talk about it a bit. 🧵

After net zero CO2 emissions do you want to halt or continue global warming?

If you want to halt global warming, the point of getting to net zero emissions, then we better define it correctly!

The key is how “removals” are defined & the role humans play.

Overconfidence in climate overshoot - Nature

Aiming for declining global temperatures can limit long-term climate risks compared with a mere stabilization of global warming, including sea-level rise and cryosphere changes.

It's currently on track for a virtual phaseout by 2030!

Representative Concentration Pathways (RCPs).

They are just one element of a bigger puzzle. Should scenarios start at concentration, or emissions, or socioeconomics? Should they start at temperature and go backwards?

All have advantages...

Coal is the first one to exit, if we want to put ourselves on track to meet the long-term Paris agreement goals. By 2030 or 2035 at the latest. Other fossil fuels to follow swift.

Let's hope that COP28 will have clear wording in the end.

The latest temperature assessments of the NDCs and LT-LEDS pledges by countries - and how they fair against the Paris Agreement temperature goals?

Surprise: We are still quite far off 1.5C.

Here an overview of all the main studies. See more at: climate-resource.com/tools/ndcs

Malte Meinshausen @meinshausen.bsky.social · Dec 11

Entering the 1.5C world, it's time for a fossil fuel exit.

Phase-in of renewables is key, but only replaces fossil fuel (emissions), if married with strong energy efficiency and dedicated coal, oil and gas phase-out policies.
