Carbon offsets fail to cut global heating due to ‘intractable’ systemic problems, study says Analysis of 25 years of evidence shows most schemes are poor quality and fail to lower emissions

Reminder - carbon offsetting is a con. We have to BOTH stop burning fossil fuels and look after nature

This is a party with virtually the same number of MPs as Reform (4 v. 5).

The way the BBC is treating Reform, compared to the Lib Dems and the Greens, is a dereliction of their duty as a public broadcaster.

This is the first party political broadcast in a very long time that understands the trouble we’re in.

Great job @zackpolanski.bsky.social 💚

Modest and gradual actions have not been sufficiently implemented while the opportunity existed.

There is no longer any way that the future can emerge in a continuous way from the present. I don’t like this but it’s true.

Physics and biology are under no obligation to be politically moderate.

Land use change emissions have been edging down the last two decades, but with a slight & uncertain tick up in the last few years.

We expect a rise in 2024, driven by fire emissions linked to deforestation and forest degradation in South America, exacerbated by temporary El Niño conditions.

We estimate that EU emissions went down 3.8%, US edged down 0.6%, & Chinese emissions edged up 0.2%.

Emissions were up more strongly in India 4.6% & international aviation 13.5%.

The record growth in renewables is helping bend the curve, just not enough to get a peak in global emissions.

📢Global Carbon Budget 2024📢

Despite some predicting a peak in global fossil CO2 emissions, we estimate growth of 0.8% [-0.3% to 1.9%] in 2024. Maybe a peak next year?

Is it all bad news, or can we find some good news?

The @metoffice.gov.uk use weather station observations to reconstruct changes in UK average temperature since 1884.

@copernicusecmwf.bsky.social produce the ERA5 reanalysis which reconstructs global weather every hour back to 1950 using a weather forecast model.

Their estimates agree. Just sayin'.

Ops...ignore that.. I see all other platforms...🙄 sorry!

Thanks for the transcript. Anywhere you can listen other than Spotify?

Transforming Food Systems Could Help Tackle Global Warming, Study Finds The study by the EAT-Lancet Commission warns food systems currently account for nearly a third (30%) of total global greenhouse gas emissions.

No safe solution to #climate & #biodiversity crisis is possible without a global food systems transformation: @forbes.com on new EAT Lancet report. Reshaping food systems could deliver returns of $5 trillion a year through better health, restored ecosystems.

This is a very valid point. It IS the global North that is causing the problem!

People always ask me 'but what can I do to help the climate?'

"Even if the world stopped burning coal, oil and gas tomorrow, what we eat would still be enough to heat the climate beyond 1.5 degrees Celsius."

Bullshit. Our best weapons against climate change is mandating the necessary emissions cuts and ending fossil fuel driven corruption

The 1.5ºC scenarios need ~8 GtCO2e by 2050, and more if there is overshoot. If actual potential is on the low side, there is a huge gap.

“The technical potential for BECCS by 2050 is estimated at 0.5–11.3 GtCO₂-eq yr⁻¹”

That’s a lot of BECCS!

Still wouldn't have been a prediction that any of these things are viable. It's basically just a residual that they could have called anything.

I think this is backwards. Projections are tasked w/coming up with pathways that meet a temperature target given various constraints. They find a huge amount of BECCS would be required to meet those targets (given imposed constraints). They are not predictions that this amount of BECCS is viable.

Many climate projections rely on a lot of bioenergy with carbon capture and storage (BECCS) for CO₂ removal (CDR). Usually the criticism is of the biomass part, but given the uncertainty in CCS, how can we be so confident about scaling BECCS?

Crack on. It ain't sustainable

The Greenlandification of Antarctica - Nature Geoscience Climate and ice sheet processes in Antarctica increasingly reflect those observed earlier in Greenland. Applying process insights from Greenland can improve projections of future Antarctic ice and climate behaviour.

The Greenlandification of Antarctica

Antarctica is beginning to behave more like Greenland, with surface melt, ice dynamics, and climate feedbacks in Antarctica exhibiting "Greenland-like” traits, which have major implications for sea-level rise projections.

I agree.

There is no wiggle room here.

If this is the emergency we claim it is, we sure better act that way!

Peacehaven: Fire at East Sussex mosque probed as 'hate crime' Video appears to show two people in balaclavas at the mosque before a large blaze spreads.

Men in balaclavas set fire to a mosque in East Sussex last night. It's only appearing on the BBC's local coverage, rather than its main national headlines, despite coming just a week after the (also under-reported) firebombing of an asylum hotel in London last week

Scientists targeted by dark PR tactics: Several academic scientists critical of de-extinction projects have become the targets of anonymous smear articles and weaponized copyright infringement claims:... EMBO Press is an editorially independent publishing platform for the development of EMBO scientific publications.

“It worries me that we humans prefer to be interested in shiny, high-tech projects as with the mammoth [‘de-extinction’]

rather than in pragmatic species conservation projects that, if managed well, can actually make a difference”
www.embopress.org/doi/full/10....

Oddly, I would have seen this as bimodal; we either top out at +1.8-2.5°C & then a slower drift down using all forms of removal, or it just keeps climbing to 3+ish, we’re impoverished, & doesn’t come back down in a human time frame, until the bio & geosphere can reabsorb the CO2 in the atmosphere 🧐

I think cheese comes straight after beef? Surprises most people!

And yet the NFUs take on the recent EAT lancet was that eating beef is fine... we're in trouble. They are are well ahead and this message is not getting anywhere near Joe Bloggs...the opposite in fact. Disaster

Can't believe the G starts with 'this is real progress' headline...making out its something...such BS. OBVIOUSLY it's not sustainable.
