Scientists:

1. Warming is underestimated.
2. Warming is faster than expected.
3. Warming of 2.5- 4°C looks certain.
4. Warming of 4°C kills 7 billion.
5. Warming of 4°C by 2049? Maybe.
6. Warming of 4°C by 2099? Likely.
7. Warming is 1 of 10 lethal threats.

Front page news? No.
State-corporate media structures help Big Business and ignore/downplay all immediate existential threats:

Overfishing
Pesticides
Deforestation
Habitat destruction
Plastic pollution
Industrialised animal agriculture
Hunting/poaching
Soil erosion
Collapse of ecosystems
Nuclear war
Warming is underestimated and faster than expected:

1.
 blogs.scientificamerican.com/observations/s…
2.
3.

Biological annihilation is also underestimated, and is virtually 100% absent from state-corporate media:
For a long time many scientists have said temperatures will exceed 2°C:


3°C or 4°C could well hit this century:

1.
2.
3.

2.5°C - 4°C now looks inevitable this century in my opinion.
Scientists have suggested that only 1 billion people could survive on a 4°C Earth:
climatecodered.org/2019/08/at-4c-…

Peer-reviewed science exists showing that warming could 'exceed 3.5–4C by 2050':
pnas.org/content/114/39…

See this thread for further details:
Billions of humans will only die if there is a failure to transform unjust/destructive systems, or if warming is too severe.

Currently billions of insects, birds, mammals, reptiles, and amphibians are being killed by corporate capitalism. Humans will perish as well at this rate.
See here as well for faster than expected:nature.com/articles/d4158…
See here for an article from two and a half years ago including well known figures commenting on how we will head over 2°C:

New research shows we're heading for rapid mass extinction at 3-5°C of global warming even if we avoid the so-called worst-case scenarios. 🧵 SSP scenarios will result in far more warming than thought
3 to 4 or even 5°C with the 'moderate' SSP2-4.5 emissions scenario.
SSP3-7.0 looks closer to reality to me, so 4-5°C.

agupubs.onlinelibrary.wiley.com/doi/full/10.10…
We should in fact anticipate 3.5-5°C by 2075-2125.

See new research from December 2024:

COLLAPSING:  scientists indicate civilisation-wrecking conditions are already developing as rapid mass extinction accelerates with billions set to be killed from 2029- 2048🧵
Current generic extinction rates likely to greatly accelerate in coming decades due to economic growth & overconsumption by the rich.
Economic activities during capitalism are destroying the conditions that make human life possible.

Plastic contamination will soon be "catastrophic" for human health and is slowly "killing the human race"

more cancer, more allergic diseases, more infertility

microplastics are everywhere

DOOM:  majority of scientists think difficult-or-impossible-to-survive warming of 1.9-2.1°C and rising is now unavoidable and set to begin wiping out species within years 🧵
1. 'New assessment warns area the size of the USA will become too hot during extreme heat events for even healthy young humans to maintain a safe body temperature if we hit 2°C'
kcl.ac.uk/news/half-a-de…

"if we hit 2°C"?

Virtually all scientists expect 2°C.agupubs.onlinelibrary.wiley.com/doi/full/10.10…
2. Even before new research confirming warming is accelerating, the overwhelming majority of climate scientists fully expected ~2°C (in most cases much more).

'perhaps half of all species will be vulnerable to thermal infertility'

COLLAPSE: scientists indicate all aspects of human societies will be wrecked by 2029-2092 as habitat destruction and pollution intensify with unsurvivable accelerating warming of 1.95-2.15°C and rising now unavoidable even with capitalism's best-case emissions reductions 🧵
1. 'Most scientists concur..2°C of warming above the temperature during preindustrial time would harm all sectors of civilization - food, water, health, land, national security, energy & economic prosperity
scientificamerican.com/article/earth-…
Best-case: 1.96°C, 2.18°C

2. Economic growth means habitat annihilation..

The economy is a heat engine.
How will it cool the planet?
Collapse is already here.
Time to rethink. 🧵
1.

Economic growth: the engine of collapse

The hope is that, with astute academic guidance and sufficiently powerful doses of political will, we can safely navigate our way through the Anthropocene. 

But there are physical limits to what is possible.
2.
To get a sense of any physical limits, it helps to look at how physical systems function. A useful concept here is a thermodynamic “heat engine”... available energy powers cyclical motions thereby enabling “work’’ to be done to move something else while giving off waste heat.

COLLAPSE: there is a very high likelihood that capitalism has condemned 2 to 7 billion people to an early death by 2038-2058. 🧵
1.

'a very high likelihood of 2.0 °C of regional warming by 2040 for the majority of regions, along with a likelihood of 3 °C by mid-century'
iopscience.iop.org/article/10.108…
2.
Report fr risk management experts the Institute and Faculty of Actuaries:

'At 3C or more of heating by 2050, there could be more than 4 billion deaths, significant sociopolitical fragmentation worldwide, failure of states..'
