🚨🥵🚨 💀 🚨 EXTREME CLIMATE HEAT ALERT. Paris is heatwave is back to 40C by next Tuesday. These are deadly conditions, especially for the poor and vulnerable, all over Europe. And this will only get worse, due to fossil fuel corruption of our governments and media. 1/7

This weekend I learned that even with: - good insulation - window shutters - triple glazing on half our windows (double on the rest) - maximum night-time ventilation ...there is no way to keep our flat naturally cool over such an extended heatwave

😧 Now do it for electric vehicle, heat pump, solar pv and healthy diet adoption

"Misinformation was estimated to contribute to nearly 2.3 million cases & 66 000 hospitalizations in 2021. Misinformation resulted in $2 billion in extra costs of hospitalization & 45 000 avertable deaths." Misinformation about COVID vaccines cost the US $2 billion academic.oup.com/healthaffair...

I have updated Tidy GHG Inventories - a dataset of greenhouse gas emissions based on country submissions to the UNFCCC. Summary figures: lambwf.github.io/Tidy-GHG-Inv... Dataset: zenodo.org/records/1969... This version has much more detailed energy sector data⚡including the split by fossil fuel 🛢️

Back in 2020, I wrote a big paper that explained why different datasets of global fossil CO₂ emissions gave different numbers. 📢Now @wflamb.bsky.social has hand-picked a crowd of experts and gone much further: "Differences in anthropogenic greenhouse gas emissions estimates explained", out today.

We have a pretty good understanding of the differences between GHG emission estimates, but when it comes to some sectors (e.g., land), estimates seem all over the place! Why is this? @wflamb.bsky.social has you covered... essd.copernicus.org/articles/18/... 1/

PIK at #IPCC: Nine PIK scientists joined the first Lead Authors’ Meeting for the 7th Assessment Report on the state of climate science in Paris last week. The meeting marked the start of drafting the 3 Working Group reports: www.pik-potsdam.de/en/news/late... @ipcc.bsky.social @wflamb.bsky.social

I think one line of evidence for this is the scale of backlash that fossil interests have mobilised against existing and working climate policies - and what happens to renewables, counterfactual emissions, etc. when they get shutdown!

It's funny to have to make this case but tbqh we don't make it enough: human efforts to counter fossil fuel use have had *at least some* effect on total greenhouse gas emissions since the signing of the Paris Agreement in 2015, and there's some evidence to back up this position A lil thread 🧵

New national climate plans have barely moved the needle on limiting global warming. Yet there is hope. According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

About 1500 of the approx. 2300 people that will have lost their lives across 12 European cities last week would still live, if it wasn't for our burning of oil, coal and gas. If we care about the right to life, we need to stop burning fossil fuels. www.imperial.ac.uk/grantham/pub...

Just did a small update of Tidy GHG Inventories: lambwf.github.io/Tidy-GHG-Inv... 81 countries have now submitted inventory data with their Biennial Transparency Reports. Quite a few still haven't (its 6 months past the deadline btw).

The land use change (LULUCF) sector is pretty confusing, since it can be a source of emissions (deforestation, disturbances) as well as a source of removals (regrowth, management). Including LULUCF can speed up, slow down, or change the overall dynamic of economy-wide emissions.

Quite possibly the biggest climate story of the year (especially when we look back on this in a few years' time) For the first time on record, China's emissions are falling due to clean energy growth, not slow power demand...

The EU has released its latest GHG emission inventory, with data up to 2023. The good news, GHG emissions continue a downward trend, currently 37% below 1990 levels. The bad news, a significant downward revision of land-use removals (LULUCF). 1/

We should make more use of ‘small multiples’ for climate data visualisation.

So the US was supposed to report its greenhouse gas emissions to the UNFCCC yesterday. For the first time since 1997, it didn't. This follows last week's revelation that Trump's EPA is stopping collection of GHG emission from 40 of 41 sectors www.propublica.org/article/trum...

Climate experts expressed shock and dismay at the move. “It would be a bit like unplugging the equipment that monitors the vital signs of a patient that is critically ill,” one said.
