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...

Höhepunkt der Emissionen noch nicht erreicht - Tagesschau Online berichtet über Report „Indikatoren des globalen Klimawandels“. Es werde immer schwieriger, die 1,5 Grad noch zu halten, je länger Emissionen nicht reduziert würden, so PIK Forscher @wflamb.bsky.social www.tagesschau.de/wissen/klima...

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...

Will Lamb @wflamb.bsky.social has pulled the troops together & submitted an article to explain why different datasets can give different estimates of GHG emissions. My favourite: differences in accounting for fire emissions. Article in review, please comment! essd.copernicus.org/preprints/es...

New preprint: differences in anthropogenic greenhouse gas emissions explained essd.copernicus.org/preprints/es...

Greenhouse gas emissions are still mostly from fossil fuels by the way!! lambwf.github.io/UNEP-Gap-Rep...

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/

I tried

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...

According to Carbon Monitor, emissions could have been 9.8GtCO2 higher in 2024... if renewable energy supply had been met with expected fossil sources instead www.nature.com/articles/s43...

I've updated the Tidy GHG Inventories dataset, which is now complete for Annex I countries: doi.org/10.5281/zeno... This also shows the progress to date in countries submitting Biennial Transparency Reports under the Paris Agreement ⬇️

Prominent climate communicators continue to "joke" that what Trump is doing is "degrowth". It is not, and such claims are actively harmful. A quick🧵

If you accept that non-citizens have no right to due process, you are accepting that citizens have no right to due process. All the government has to do is claim that you are not a citizen; without due process you have no chance to prove the contrary.

This looks like a very interesting piece on interest groups at the COPs www.nature.com/articles/s41...

I asked CLARA - @oxfordsmithschool.bsky.social's new LLM trained on historical climate obstruction documents - about fossil fuel companies' internal discussions and strategies on carbon dioxide removal 😬 clara-research.com

‼️The US-based @ipcc.bsky.social technical support unit (TSU) for Working Group 3 Co-Chairs has been terminated, and the US won’t be attending next week’s IPCC meeting where the AR7 chapter outlines will be approved. More by @afreedma.bsky.social here:

On climate protest, a superb point from @richarddenniss.bsky.social. If protest wasn't effective, govts wouldn't try to ban it. And as much as politicians like to talk about parliamentary logjams, as soon as fossil capital is threatened, they mobilise with extraordinary rapidity and efficacy.

I just love this figure from @jksteinberger.bsky.social in their paper on "Discourses of Climate Delay". You can find all the arguments of your colleagues and influencers taking the world in the wrong direction. Perhaps we need another paper rebutting each? www.cambridge.org/core/journal...

Sweden is one of a handful of countries that has been reporting net negative GHG emissions for a number of years. lambwf.github.io/Tidy-GHG-Inv... If you are wondering "how is that possible?" its because the definition of land use change removals in inventories is very inclusive...

Here is the issue that has caused so many headaches among climate mitigation researchers - inventory estimates of net land use change emissions differ substantially from global bookkeeping models. lambwf.github.io/UNEP-Gap-Rep...

I revamped my page with ghg emissions plots and data from the UNEP Emissions Gap Report. 👇 lambwf.github.io/UNEP-Gap-Rep... I'll be adding to this a bit in the coming months.

We just published a map of climate policy research. It has lots of useful resources, including a new typology of instrument types and a literature hub where you can search for studies by sector and instrument: climateliterature.org#/project/pol... www.nature.com/articles/s44...

China's latest national GHG inventory submission (common reporting table) to the UNFCCC ... 🤔

Countries can classify emissions from wildfires (and subsequent removals from regrowth) as a memo item in their national greenhouse gas inventories, excluding them from the total. So far Australia and Canada have done this - including Australia's massive 2020 wildfire.

1. This is what it’s really about. Farage, Truss and co have no convictions of their own. They are mere channels for the demands of capital. Here they are, supporting a climate science-denying lobby group funded by oil and oligarchs. www.theguardian.com/environment/... 🧵

One of the frustrations of the German academic funding scene (and presumably elsewhere) is the common requirement for co-financing. a.k.a. "You can apply for this grant, as long as you pay x% of the costs." Fine if you have a core funded position (just count your own time). Not fine if you don't.

New dataset: Tidy GHG Inventories (zenodo.org/records/1451...) I extracted emissions data from the national inventories and put it into a tidy, consistent format. The kind of format that I would actually use.

Just published a paper in Nature Scientific Reports where we've trained a model to automatically detect logical fallacies in climate misinformation - part of our project using AI to debunk climate myths www.nature.com/articles/s41...

The International Court of Justice is working on an advisory opinion on the legal obligations of countries in preventing climate change. I helped a team of IPCC authors to prepare evidence for the court, which was delivered yesterday. www.icj-cij.org/sites/defaul... @pik-potsdam.bsky.social

Your bicycle is not surveilling you.

Indonesia emissions - hopefully phasing out coal doesn't mean phasing in bioenergy. Do we know more about what exactly the "75 gigawatts (GW) of renewable energy" target means? lambwf.github.io/UNEP-Gap-Rep...

A postcard from the future in multiple ways - I think this will be one of the first countries where we get to see if the frontier of decarbonisation can push into other sectors lambwf.github.io/UNEP-Gap-Rep...

I think an important precondition for this is that countries actually start to distinguish emissions reductions from removals in their pledges, and then do the needed disaggregation. We have some practical suggestions: iopscience.iop.org/article/10.1...

When countries update their NDCs in the next year, it would be cool if they told us how much carbon dioxide removal they have in mind... iopscience.iop.org/article/10.1... #COP29

Now that more countries have submitted national GHG inventories in the latest format, I'm starting to write a bit of code to compile it all. Initial impressions: these sheets are better organised, but there are still so many quality of life improvements to make... unfccc.int/ghg-inventor...

Inspired by @elliemaeohagan.bsky.social, here are the beginnings of a list of women working on energy - around 100 so far. As it's curator, I've been included by default, but you can just delete me of course. And please tell me who I've missed!

My academic pet peeve: random unnecessary latin phrases pro-et-contra sine qua non all that nonesense

More info on that big drop in EU emissions last year: ec.europa.eu/commission/p... Pretty good news. But I'm not sure that land sink trend is going to last (up by 8.5% 🤨)

Do you want greenhouse gas emissions data, for your favourite country, by sector, & by GHG, in csv, png, or pdf? Look no further... @wflamb.bsky.social lambwf.github.io/UNEP-Gap-Rep...
