BREAKING: abrupt climate change is rapidly warping Earth's fresh water cycle relied on by human societies for tap water with scientists warning of potentially disastrous changes faster than previously thought 🧵
1/Fresh water will always come from the tap. Won’t it?
Unfortunately, that’s not guaranteed. Climate change is shifting where the water cycle deposits water..
2/State-corporate media journalists are very quiet on the extraordinary threats now facing hundreds of millions of people around the world, and on those rapidly approaching.
We face 1.6°C-2°C hell by the 2030s without a shift away from economic growth.
4. Climate models: 2.5°C by the 2040s is entirely plausible; 3°C by 2048 isn't totally impossible, and looks increasingly likely by 2058-2094 as emissions rise to record levels.
6. We're near 425-450 ppm of atmospheric CO2 and emissions are rising to record levels. No wonder most climate scientists expect 2.5°C-3.5°C or more in the second half of the century.
Even lower emissions scenarios could mean 1.8°C-2.2°C by 2050.
7. Who dare disagree with these IPCC climate scientists?
'Most of the survey’s respondents — 88% — said they think global warming constitutes a ‘crisis’, and nearly as many said they expect to see catastrophic impacts of climate change in their lifetimes.'nature.com/articles/d4158…

1. the destruction of primary tropical forests would lead to the extinction of 75% of species by 2200 even if dangerous climate change didn't exist
2. scientists say all deforestation of the Amazon must end by 2025 for a chance of avoiding catastrophic collapse
1. Economic growth = extinction:
'tropical forest loss/degradation alone, even without considering other human stressors such as climate change & habitat loss in other ecosystems, will precipitate a mass extinction event over the next couple of centuries'.pnas.org/doi/10.1073/pn…
2. It's possible the severe tropical forest fragmentation that has already occured means collapse is no longer avoidable given the severity of global warming yet to come. We're in tipping point territory and only economic system change will do.
Anyone else troubled by the total state-corporate media silence on profoundly catastrophic biodiversity destruction and abrupt ecosystem change at horrific 1.6°C-2°C of global warming by 2032 assuming no economic system change?
1. We can protect people and animals, species and ecosystems if we change the economic system, otherwise we're heading for 1.8°C-3°C by 2048-52. Climate justice activists have been making this clear for years, decades..
2. The idea economic growth could limit warming to 1.6-1.7C by 2050 is utterly implausible in my opinion (the IPCC's best case scenarios). Besides, this short term profit maximization system won't look after people or any other living beings.
Climate models show 1.5°C-1.7°C will hit by 2029 without immediate economic system change.
System change may delay 1.5°C-1.7°C even if it can't prevent it.
And anyway, it's crucial: this system won't protect us at 1.5°C-1.7°C.
1. We can protect people and animals, species and ecosystems if we change the economic system, otherwise we're heading for 3°C-4°C by 2065-2100. Climate justice activists have been making this clear for years, decades..
The best we can realistically hope for with this economy is unimaginable destruction of Earth's biodiversity plus unmanageable damage to human agriculture due to very high global warming impacts, habitat destruction & pollution, all by 2045. Where are the system change headlines?
1. 'Globally, the percentage of species at high risk of extinction will be 9%-14% at 1.5C, 10%-18% at 2C'.
1.75-2.5°C by 2045.
'Among groups containing the greatest numbers of species at high risk of extinction are invertebrates (especially pollinators)'.carbonbrief.org/scientists-rea…
The IPCC's methods are failing to capture a shocking trend: carbon emissions from tropical deforestation this century are far higher than previously thought, doubling in just two decades and continuing to accelerate. 🧵
'Deforestation and forest carbon loss are accelerating.
The standard methods used by the IPCC are not spotting some of the things we’ve seen in this paper..They aren’t really capturing the trend that we’ve seen in the last two decades'.
"The current global growth Economy will definitely take us to unthinkable suffering, death and extinctions at 1.8°C or more of global warming by between 2030 and 2090 unless we achieve profound political and economic system change."🧵
1. 'If temperatures rise to between 1.7 and 1.8C above the 1850s level, then the report states that half the human population could be exposed to periods of life-threatening climatic conditions arising from heat and humidity.'
2. If we get on to a lower emissions pathway in the coming years (emissions are rising towards record levels by 2025) we risk horrific 1.8°C as early as 2030.
