UK plans scheme to suck CO₂ from the air Ministers are to start negotiations with the Swiss firm Climeworks as part of the government’s new zero strategy

@climeworks.bsky.social could be getting into CO2 removals in the UK

Energy secretary Ed Miliband has begun talks to set up the UK’s first commercial project to suck carbon dioxide directly from the air and store it in old gas fields under the Irish Sea

The Long Heat Warming is about to hit one and a half degrees, perhaps two degrees soon after. What do we do then? In the overshoot era, schemes abound for muscular adaptation or for turning the heat down at a later...

The Long Heat, the book by Andreas Malm and I on carbon removal and geoengineering, will be released by @versobooks.bsky.social in October. It's available now for pre-ordering:

Trees are like people: they like food, get sick, struggle when it gets too hot or too wet, & die.

We need to be careful including trees in climate targets, particularly when we keep serving them food in a warming climate.

Yet, most countries include all trees!

Just stunning at how quickly Greece has transformed it's energy mix.

In a decade, coal has been pretty much driven out from 50% to 6%

More to come as solar expands 👍

CO2 emissions from Land-Use Change (LUC) have been relatively flat for decades, but have declined in the last decade. Uncertainty is high!

The estimate is based on four "Bookkeeping Models", but have many shared input data.

Pleased to see this paper out!

Are the values in Table 8 on the RCB correct? Subtracting a correction of 370 GtCO2 from the 83% percentile of AR6 would give -70?

Elon needs a bigger tax break so Trump is going to kill off tens of thousands of manufacturing jobs, a couple dozen clean manufacturing facilities, and billions in private investment.

Fifty years of green hydrogen in five charts It is over fifty years since Japan's "Sunshine Project" started governments pouring money into green hydrogen as a replacement for fossil fuels. How is it going? TLDR: not well.

Subscribe to read Bloc is within one percentage point of meeting greenhouse gas emissions reduction target by 2030

The EU is set to announce that it is on track to cut planet-warming emissions by 54% by 2030 (relative to 1990 levels).

The legislated target is 55%.

Chart of BEV versus H2FC sales but quarter since 2015, drawn on the same scale. BEV sales grow, H2FC sales are invisible - the chart looks the same as it did when first published in 2017.

Today's #HydrogenSoufflé is an update of a classic. I'm very much looking forward to the launch of the BMW iX5 Hydrogen in 2028, and seeing whether it can manage a single pixel on the RH chart before being taken off the market.

Fires Drove Record-breaking Tropical Forest Loss in 2024

I’ll says this once:

We’re spending a lot more on mitigation (e.g., renewables) than on CDR research. A lot more.

It could simultaneously be true that CDR research acts as mitigation deterrence and we need to do CDR research.

Trees will not be enough to reduce atmospheric CO₂.

How to boost the policy impact of climate advisory bodies - Tyndall Centre for Climate Change Research A new study examines how advice from climate advisory bodies, such as the UK's Climate Change Committee, can better influence climate policy.

🏛️ Not all advice lands equally.

🗣️ New research shows short, clear and repeated climate advice = better uptake.

CDRXIV CDRXIV is a new open access platform for sharing preprints and data related to carbon dioxide removal (CDR).

Climate change is happening quickly. Solutions research needs to move at a speed that meets the challenge. We're launching @cdrxiv.org, a new preprint server for CDR research, because transparency and collaboration help move the field forward. Let’s make better CDR, together: cdrxiv.org

In short, net zero by 2050 is far from arbitrary and the Conservatives supported the scientific rationale underpinning net zero until late.

Now they are walking away from the cross-party consensus and their legacy of leadership on the matter.

Given we will move from importing fossil fuels from a handful of countries, to minerals and metals from a large number of countries, decarbonisation reduces trade risks. By some estimates, net zero reduces trade risks by 25%.

On whether net zero would leave us reliant on foreign interests, simply put, decarbonisation is the route to national security.

Modelling by the CCC since has confirmed that costs have got lower since Skidmore's report, and net zero likely results in net savings across the economy as early as 2042 onwards. Net zero pays off quite quickly.

The report itself was requested in 2018 by a Conservative minister, Conservative ministers spoke at the launch of the report, and lobbied for it in Parliament. Bowie previously praised the target himself in the past.

On 1. the Committee on Climate Change (CCC), led then by Conservative peer, Lord Deben, published in 2019 'Net Zero: The UK’s contribution to stopping global warming', a 277 page report on the proposed net zero target. Around 111 pages of the report are dedicated to explaining the science behind it.

2. and '[There is] no way of reaching that [net zero by 2050 target] without making ourselves poorer or without being more reliant on foreign interests for our energy needs.' ❌

Both are simply wrong, and go against the Conservatives' previous leadership on the matter.

Andrew Bowie MP, the Shadow Energy Minister, quoted in today's Guardian, claims:

1. 'There’s no scientific rationale for choosing 2050 as the point to which we should reach net zero', that Theresa May's 2019 net zero target was 'arbitrary', ❌
