3. 'Joe Biden's new NASA chief climate change adviser' is a dig at journalist-speak - 'chief'? hackneyed rubbish!
4. Surely we *should* now be prepared (materially, psychologically) for the possibility/likelihood of approaching or just over 3C? my mistake?!
5. There is every reason to think 2.3C will not protect biodiversity meaning billions will be at risk - if @ClimateOfGavin really isn't clearly prompting people to think that, it may mean they've not been informed about the ecological crisis by media, schools, governments, etc
Here's the text of the tweet which I deleted:
1.
'BREAKING: Joe Biden's new NASA chief climate change adviser has made clear that even with aggressive emissions reductions we should be prepared for global warming levels that will
2.
likely wipe out half of Earth's species and threaten the lives of billions of people this century.'
1) Earth's climate is set to suddenly revert back to that of 3 million years ago by the 2030s
2) 18 of the 37 highly dangerous climate change tipping points in IPCC models will then be triggered
3) humans have never experienced anything like this
4) we can still act
Climates like those of the Pliocene as soon as 2030, likely by 2040 (Mid-Pliocene: 1.8°C-3.6°C).
'Both the emergence of geologically novel climates and the rapid reversion to Eocene-like climates may be outside the range of evolutionary adaptive capacity'!pnas.org/content/115/52…
We're heading for 1.8-1.9C, using a 1750 baseline, by the 2030s (or even using a 1850 baseline.. 2C by 2034 is shown as possible by climate models).
'With global temperatures already about 1C higher than pre-industrial levels, Queensland’s Great Barrier Reef has been through three mass bleaching events in only five years'
scientists: primates are being driven to extinction by market demands leading to massive habitat loss through expanding industrial agriculture, large-scale cattle ranching, logging, drilling, mining, dam building, & road construction
media: let's keep this fine economic system
'Globally, agriculture is the principal threat, but secondary threats vary by region.'
🔺This isn't a 'climate' emergency, it's an economic growth emergency, a capitalism catastrophe ('there are also emerging threats, such as pollution and climate change')advances.sciencemag.org/content/3/1/e1…
Is food production primarily about feeding people (4.2 billion people undernourished, 20 - 45% of food produced is lost/wasted), or making vast amounts of money for a small group of ultra-wealthy people (there are 2,000 - 3,000 billionaires and 5 - 6 billion live in poverty)?
1. Trees face extinction. 2. Ecosystems are unstable. 3. Crops are vulnerable. 4. Pollinators risk extermination. 5. Water supplies are shrinking. 6. Soils are dying. 7. Primates may not survive. 8. Forever Chemicals are in our blood.
Is global warming of +2C now unavoidable and likely to occur by 2029-2038 without emergency system change causing the demise of forests, putting world agriculture at high risk, and triggering 1.75-2.25m of sea level rise within decades leaving the world's major cities underwater?

"we need to reduce emissions as quickly as possible - if we do that, we will still break 2C, but it will be hundreds of years in the future."
Using a 1850 baseline (or 1750 baseline, my rough estimate) we might expect 2C between 2034 (2029) and 2052 (2047) in the highest emissions scenario, with a median year of 2043 (2038).
Now we know scientists are projecting severe climate disruption and ecosystem collapse by around 2038 which will make it hard for every human to live we can start making some informed decisions together regarding how to create rapid emergency worldwide system change for survival.
At 2C “you are having impacts on most people, impacts on the market, that make it hard for everyone to live"
