Crossing climate tipping points "would lock the world into a new and hellish 'hothouse Earth' climate far worse than the 2-3C temperature rise the world is on track to reach."

Probably fine.

Point of no return: a hellish ‘hothouse Earth’ getting closer, scientists say

Continued global heating could set irreversible course by triggering climate tipping points, but most people unaware

Greenhouse gas concentrations keep rising. The planet keeps warming in response. And that added heat shows up in the extremes and impacts. This is really basic stuff.

Data from gml.noaa.gov/ccgg/trends/

Graphic shows three line graph time series of monthly carbon dioxide abundance in ppm (blue line), monthly methane abundance in ppb (red line), and monthly nitrous oxide in ppb (purple line). Graphs are all shown from January 1984 through January 2026/October 2025. Current levels of CO2 are 429 ppm. Current levels of methane are 1946 ppb. Current levels of nitrous oxide are 339 ppb. All graphs show long-term increasing trends along with some interannual variability and seasonality.

Wonderful talk. The best of the maybe 10 I saw over the years. Some slides are made for beginners. Emotion and ethics r pointed out. Attention pulled to experts in lying, eg 🇨🇦Carney and the now-IPCC chair Skea.
And calls for self-empowerment: push for progress within your radius so it can spread🕸️💪

A wonderful talk. IMO, the best of the maybe 10 I saw over the years, better than the NEbriefing one too, wrt slides and performance/act. Seeing WG2 highlighted had me💃!!
Lots to talk about with others.
But let me tell you wrt equity & CO2budget: non-dev'ed countries do not need the same pc CO2.

On all fronts: how to end aviation exceptionalism

James Maclaurin, Elisabeth Ellis and James Higham

ABSTRACT
We argue thataviation xceptionalism is both a demand side and a supply side problem.Despite exponentialincreases in demand for international air travel, plane makers have achieved only modest linear movement toward low carbon aviation technologies. Meanwhile, the global aviation regime has become adept at shaping user practices and culture to enable and encourage unconstrained air travel consumption.This has influenced the public’s perception of possible regulatory regimes and, along with persistent overestimation of technical debt, has prevented the use of regulations similar to those that are successfully moving the automotive sector to new low-carbon technologies. On the supply side, there is no realistic prospect of attaining sustainable aviation technology without a government-led, private-sector supported, moonshot-style collective effort. On the demand side, the psychological barriers to behavior change will not be resolved without confronting the drivers that ‘create’ air travel consumption and artificially accelerate demand.

Introduction
We have long known about the potentially catastrophic consequences of climate change (IPCC 2022). We have also known, in broad terms, what we need to do to avert disaster (Stern & Stiglitz, 2023). All successful solutions involve some mix of social/behavioral change, regulation, scientific discovery & commercialization of technological innovations (Geels & Kemp, 2007). Results have been mixed. 30 years after COP1 in Berlin there are still domains in which none of these strategies has had a significant effect on carbon emissions and radiative forcing more generally. This paper takes international aviation as an example of such an intractable domain… Reasons given for exceptions… no longer justify the exceptional status of international aviation…

Ach ja. I tend to snort hopium, sorry. You're right of course.
And these 700Gt CO2 bound in rewilded areas currently in use for animal agri are also not safely stored in the new/old biomes. If climate keeps changing bc we keep emitting, they can go up in flames-eq too.

Shifting global food production to plant-based diets by 2050 can sequester 99–163% of the CO2 emissions budget towards limiting climate warming to 1.5 °C.

Not even for peat. Local climate impacts are too unpredictable for any biogenic CDR to provide certainty comparable to the guaranteed emissions from burning lithospheric carbon (oil/gas/coal), from AMOC risks to other feedbacks, especially as we've yet to demonstrate any effective global mitigation.

Kevin Anderson @kevinclimate.bsky.social · 26d

Agreed, but biogenic CDR is inherently temporary & uncertain, unlike the effectively permanent & guaranteed emissions from burning lithospheric carbon (oil, gas, coal). So use it to offset warming from unavoidable agricultural emissions, but it must not be used to compensate for fossil fuel CO₂.

Well, the circumstance we are now in with the climate (that we all depend on to meet our needs) rapidly collapsing, means that those who are well off need to *accept* that many of our wants really aren't needs. That's necessary to "serve the poorest first," and for "the best for future generations."

I’ve little time for the elitist gong system. With occasional exceptions, it rewards those already privileged & who reinforce the establishment rather than challenge it. A scattering of minor honours for the underpaid/volunteers is moral camouflage for rewarding compliance & for flattering power.

2️⃣ Professor @kevinclimate.bsky.social: we're using up the carbon budget for staying under 2°C at 0.7% every single month, with a small but very real risk we could reach a catastrophic 4°C by 2100.

There are huge benefits for the majority if we address climate change.
