Worth knowing:

#EarthDay 2011 - only 'herculean efforts' in the 2010s & 2020s will avoid 'billions' of lives being threatened by the 2060s

#EarthDay 2021 - pollution projected to surge to new heights by 2022

Media are still silent on corporate crimes against humanity & nature.
The emergency economic system change action now required in 2021 - 2030 and beyond is staggering.

'without herculean effort we're on our way to a 4 degree warmer world.. it's extremely unlikely that we wouldn't have mass death at 4[degrees]C'

From 2011:smh.com.au/business/on-co…
From 2009:

"..a 4C rise could come by 2060 or 2070, depending on the feedbacks."

'Soaring emissions must peak and start to fall sharply within the next decade to head off a 2C rise, he said. To avoid the 4C scenario, that peak must come by the 2030s.'
dumptheguardian.com/environment/20…
'projections for 2021 show emissions are likely to end this year still down slightly on 2019 levels, but on a rising path. Next year there could be even stronger rises' dumptheguardian.com/environment/20…
This more recent study confirms 4C by 2050-2100 is increasingly likely because emissions still aren't falling.

We must force zero emissions by 2025-2030 for a reasonable chance of decent human survival in my opinion. Some scientints suggest 2035.

Ecological Crisis: total system change, or hell on Earth

'The only way to keep humanity safe is the immediate and sustained radical cuts to greenhouse gas emissions in a socially just way'

Net zero policies: 'driven by a need to protect business as usual'theconversation.com/climate-scient…
It was a very different message from one of the authors Sir Robert Watson in May 2019:

'the good news is that there are many policies and technologies that will limit global temperature rise and address the conservation and sustainable use of biodiversity'dumptheguardian.com/commentisfree/…
'Sometimes realisation comes in a blinding flash.. Why has it taken us so long to speak out about the obvious dangers of the concept of net zero? In our defence, the premise of net zero is deceptively simple – and we admit that it deceived us.'

Remember:

1. bees declining
2. ice disappearing
3. emissions surging
4. ecosystems collapsing
5. photosynthesis malfunctioning
6. oceans overheating
7. overconsumption rising
8. primates vanishing
9. chemicals accumulating
10. penises shrinking

This economy is not sustainable.
Capitalism is blocking ecological-climate emergency action for short-term profit maximization. The economy is endangering billions of lives.The UN says global food insecurity is on the horizon.

1. The recent 'dramatic decline' in bees: a 'stark scenario'. biology.indiana.edu/news-events/ne…
We must force transformative economic-political change & emergency action in the 2020s for decent survival.

The American Geophysical Union is telling the world that climate danger only hits after doubling CO2 levels to 560 ppm!

Isn't this utterly false?!?

Doesn't 400 - 500 ppm correspond to profoundly catastrophic levels of heating?

Mightn't 550 ppm lead to an uninhabitable Earth?!?
1. My criticism is generally of state-corporate media systems not scientific institutions (any comment, @nowthisnews?), but surely AGU shouldn't be sharing this article?
2.
'Doubling pre-industrial CO2 levels has a 95% chance of warming the planet by at least 2°C... Scientists believe that beyond this threshold, climate change will lead to disastrous sea level rise and other extreme weather events.'

560 ppm may mean 5.7C!nowthisnews.com/amphtml/earth/…

You know you're living in a world of state-corporate media propaganda when you click that just like today scientists and politicians in the 1980s were calling for huge decreases in greenhouse gas emissions within 12 years due to fears over global warming and it's still not news.
1.

'An international conference of scientists and senior politicians in Toronto last June called for a 20-per-cent decrease in emissions by the year 2005.'

newscientist.com/article/mg1221…
2.
Look in the supplementary materials of the peer-reviewed science discussed here and you may come to the conclusion that not only may 1.5C & 1.75C be impossible targets, but that 2C may be virtually impossible too.

(in fact committed warming is >2.5C!)theconversation.com/new-research-s…

Remember

1. Somewhere between 350 and 450ppm is the CO2 concentration level in the atmosphere that poses an irrevocable danger to life on Earth

2. We're heading for 450ppm by 2035

3. 550ppm may be unsurvivable

4. We're heading for 550ppm by 2050-75

5. We must stop emissions
We need immediate emergency system change action.

'Many scientists pegged 450 ppm as a red line, while others have said 350 ppm—which the Earth passed years ago—is the safe upper limit.'

We need an Ecological-Climate Crisis global ceasefire to end the fossil fuel war economy.

Rich nations must slash their energy use and consumption whilst giving money to those nations suffering from damage already done.

ECOLOGICAL EMERGENCY

Which statement best describes the current climate chaos situation?

a) avoiding +1.5°C may be possible

b) long-term warming expected from today's +500ppm CO₂-e is at least 2.5℃

c) temperature rises of 3- 4°C are likely now locked in

d) all of the above
Scientists differ on whether this statement is appropriate:

'The Australian Academy of Science says the more ambitious target of the Paris Climate Agreement of keeping global warming to 1.5 degrees has now slipped out of reach and is “virtually impossible”smh.com.au/environment/cl…
State-corporate media remain silent on this:

'Atmospheric scientists use CO₂-e as a convenient way to aggregate the effect of all the long-lived greenhouse gases..

The best estimate of long-term global warming expected from 500ppm CO₂-e is about 2.5℃.'theconversation.com/why-theres-mor…
