BREAKING: Earth's 8.7 million species call for immediate system change
60% of primate species are threatened with extinction, 75% are declining.

Main threat: habitat destruction due to logging/agriculture.

Hunting, road construction, oil & gas extraction, mining, pollution, disease, and climate change are also key threats. theconversation.com/60-of-primate-…

We are in an abrupt climate-extinction experiment during ultra-destructive capitalism/imperialism.

It will never be too late to try to protect species and everybody by aiming to limit the damage via rapid, profound system change.

Thread:

At least a quarter of the world’s estimated 8.7 million species might already be on the move, experts have warned, pushed out of their habitats by the changing climate and human activities.

18% of the world’s plant species & 22% of mammals will go at 2°C.
euronews.com/green/2020/11/…
Climatically determined geographic range losses of >50% are projected in

* 49% of insects, 44% of plants, and 26% of vertebrates at 3.2°C

* 18% of insects, 16% of plants, 8% of vertebrates at 2°C

* 6% of insects, 8% of plants, 4% of vertebrates at 1.5°C

'Our findings strongly suggest that where species can survive in nature is determined by the temperature at which males become sterile, not the lethal temperature.

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

So, at 1.5C-2.5C?phys.org/news/2021-05-i…
A common fingerprint of a warmer world is a range shift..

80% of relevant studies found fingerprints among species, from grasses to trees and molluscs to mammals.

A recent review found 8-50% of all species will be threatened by climate change as a result.theconversation.com/climate-change…
Earth may be heading for far more extinctions than previously anticipated

2℃ dramatically reduces coral sperm bundle production/egg size

Salinity, chemicals, poor nutrition may compound thermal infertility

Do findings extrapolate to mammals like humans?theconversation.com/fly-infertilit…
Human society is yet to appreciate the implications of unprecedented species redistribution for life on Earth. Even if greenhouse gas emissions stopped today, responses required in human systems to adapt to the most serious effects would be massive. science.org/doi/10.1126/sc…

BREAKING: abrupt climate change will more than triple thе proportion of cropland affected by drought by the 2040s
Analysis of corporate media is essential with much useful information to be found.

But a basic reality is omitted: we're heading for >460 ppm of atmospheric CO2 and 2°C horror by 2036-2045.

Fair emergency action to protect everyone may yet be achieved. bloomberg.com/news/articles/…
'BREAKING' is ironic as we've known for years that crop yields will be negatively affected by climate change much earlier than once expected:

'we will see, on average, an increasingly negative impact of climate change on crop yields from the 2030s onwards'phys.org/news/2014-03-c…

Dr James Hansen, climate scientist, 2008:

"If you leave us at 450ppm for long enough it will probably melt all the ice - that's a sea rise of 75 metres. What we have found is that the target we have all been aiming for is a guaranteed disaster".

Our trajectory: 450ppm by 2032.
1. "if we follow business as usual I can't see how west Antarctica could survive a century. We are talking about a sea-level rise of at least a couple of metres this century."

That wrecks coastal cities.

Corporate media like Gdn are now silent on 450ppm.

2. Rapid transition to a postgrowth economy via careful, emergency, climate justice action is required now. It'll be extraordinary if we avoid 2C by 2035-2050 but we must try to limit the damage and protect everyone. Today's growth economy must go.

Editors and journalists are shamefully silent on the scientific projections that show without action on inequity billions of people exploited in poverty will face multiple high level food, water and energy risks from 2026-2035 due to ecological collapse and abrupt climate change.
1.

State-corporate media are busy protecting today's ultra-destructive global growth economy of which they are a key part and so only occasionally pay lip service to crucial ideas of climate justice.

It's not too late for fair, radical system change.

⬇️
2.

To limit the damage and suffering requires profound system change.

Until all of us - our families, friends, and acquaintances - are aware that global warming of 2°C could cause major dislocations for 'civilization', and that this looks increasingly likely to happen by between 2036 and 2045, there will be no action to try to protect everybody.
Global warming of 2°C may cause 'major dislocations for civilization' climatenewsnetwork.net/2c-rise-will-b… and this looks likely to happen 'by 2045' nature.com/articles/d4158… and in fact 'at our present pace of fossil fuel burning we will, by 2036, exceed the 2°C limit' theconversation.com/amp/limiting-g….
Is this 'civilization' ..?

(2°C probably means 2.5°C becomes inevitable.)

Seagrass meadows can bury carbon in underwater sediments 40 times faster than tropical forests bury it in soil, providing one of the greatest contributions to the total carbon buried in ocean sediments. They are being destroyed at a rate of around 7% each year.
1. Kids deserve to be educated properly. Where is the explanation of capitalism's obvious role in the destruction of species and ecosystems?

kids.frontiersin.org/articles/10.33…
2. '10 of the 72 known seagrass species (14%) are at an elevated risk of extinction, while 3 species qualify as endangered', however, though 'researchers listed 48 species (67%) in the "Least Concern" category, most of these species..are declining'

40%-60% of Earth's trees and other plants including crop species face extinction due to a combination of today's for-profit industrial agriculture, logging, road-building, construction, mining, etc, etc, and current & near-future abrupt climate change.

Where is the media frenzy?
1. The living world is being wrecked by for-profit agriculture and the global economy as a whole.

Technology is useless when ecosystems permanently collapse.

2. I cannot imagine capitalism protecting forests in a meaningful way. It's much easier for me to imagine necessary alternatives to capitalism.

We must now create a Postgrowth economy.
