CO₂

1. We're at 417ppm
Dr J. Hansen: that's 3.5°C eventually

2. We face 427ppm by 2025
That's like climates +3M yrs ago

3. Business plans: +450ppm by 2035
Scientists: worst impacts likely

4. Trajectory: 550ppm by 2047
Decent human survival threatened

5. Action: now or never
We're in an Ecological Catastrophe.

However, it's not too late to calmly take emergency individual-collective action to change consumption and production, organising for political and economic system change away from growth & corporate crimes.

More information to explore in these threads :

Decent human survival has been threatened since the '80s when we hit 350 ppm. The threat keeps growing, and now we're likely to remain in the extreme danger zone of 350-400 for hundreds of years (assuming we survive WMDs, pandemics, soil erosion, plant/insect extinctions/declines

More than half of the world's 60,000 tree species are now vulnerable to potential extinction threats like accelerating deforestation and unprecedented levels of heat by the 2030s with staggering implications for all life on Earth. Image

Even today, without runaway climate change, we're already suffering. We don't want people to be hopeful, we want people to be angry and we want people to act.

A lot of room given to a climate justice activist in this @NiranjanAjit article. Great to see.

The 2 big omissions:

*this is a capitalism/ neocolonialism/imperialism crisis or catastrophe

*this is an ecological crisis or catastrophe

I find it remarkable to mention nuclear weapons without confirming that total collapse at any time is possible and has been for many decades. A nuclear war would collapse civilization and kill pretty much everything.

You already know that 20% of all species face extinction in the next few decades that's why you're taking whatever emergency individual action you can and striving for profound economic & political change, but did you realise at least 40% of Earth's plant species are threatened?
1. Researchers say there are still huge gaps in our knowledge about plants, the implication being it would seem that it is perfectly likely more than 40% face extinction.

2 The IUCN estimates that some 20% of all species are in danger of extinction over the next few decades,

10 years ago to the day, Dr James Hansen explained that if we continued Business As Usual until 2021, then suddenly stopped all emissions, we'd remain at risk in the climate danger zone above 350 ppm until 2300.

Continue until 2050?

We stay in that danger zone for 1000 years.
@DrJamesEHansen on abrupt climate change, April 2011:

"We're creating a problem which will soon be unsolvable."

'If reductions are delayed until 2030 or 2050, CO2 remains above 350 ppm or 400 ppm, respectively, until well after 2500.'

If you think capitalism is a system that will let butterflies, giraffes and bumblebees flourish, you might be out of your tiny mind.

And while we're on the subject.. think you know human nature is essentially destructive to the point where we must wreck our own habitat? Also no.
Migratory western monarch butterflies have reached a record low this year, putting them at the brink of extinction.. the U.S. Fish and Wildlife Service announced.. it would not be recommending protection for the species under the Endangered Species Act.'nationalgeographic.com/animals/articl…
'Giraffes are in serious danger of extinction'.

'Conservation groups are suing the U.S. Fish and Wildlife Service for failing to respond to a petition seeking protection for giraffes'

Biggest threats: illegal hunting, habitat destruction, fragmentation.

There are many things we can do to try to limit the damage of the ecological-climate crisis.

1. explore Climate Justice & Degrowth Economics to aim for individual-collective action. Make personal changes of course, and also join others to organise and influence policies/systems.
2. One of the most useful and important things we can do is inform ourselves and each other. With wider awareness comes deeper change.

See the detailed, thoughtful article linked here for practical tips on concrete ideas for taking action:

3. Here's a very realistic, helpful, positive thread on taking action:
