Do climate and energy experts often ignore the fact we're in a mass extinction that's now accelerating during 21st century capitalism because it disrupts their visions of 'solutions'?
THREAD. 🧵
1. We're in a mass extinction due to habitat destruction, pollution, and many other factors including abrupt climate change: 20% (30-50%?) of species face extinction by 2050, and 75% of mammals as early as 2300.
We don't know which species can survive 1.75°C-2.75°C by the 2040s.
2. It seems many climate and energy experts say climate change won't lead to human extinction within decades or centuries, without acknowledging that extinction threats to species come from a range of activities likely to be maintained in a 'green' growth, 'clean' energy economy.
3. Climate & energy experts should discuss climate change in terms of mass extinction & ecosystems collapse, not just emissions & technology, and acknowledge that a key question is whether, or in what ways, billions of people are, or will soon be, in danger.
4. The near-term obliteration of 20%-50% of the species humans rely on for survival due to the activities of this growth economy would obviously be utterly horrific.
"Will humans become extinct due to climate change?" is a red herring.
7a. 'In around 300 years time, 75% of all mammal species will have disappeared from this planet... if the current rates of extinction continue and the animals already threatened or endangered are wiped out this century.' bbc.com/future/article…
7b. 'Once-common species will be extinct, or exist only in human-made environments like zoos or private breeding colonies far from their natural habitat, such as the lemur sanctuary in the Caribbean that Virgin boss Richard Branson proposed'.
1.75°C-2.75°C by the 2030s or 2040s will be horrendous.
(Maintaining the current economic system would in theory make 1.6°C by 2050 possible, but would mean wrecked ecosystems and unbearable pollution, etc)
System change required immediately.

12. "temperature-driven fertility losses may be a major threat.. We already had reports of fertility losses at high temperature in everything from pigs to ostriches.. even humans..perhaps half of all species will be vulnerable to thermal infertility." phys.org/news/2021-05-i…

1.'Material extraction & use are climbing year on year
In only 50 years, global use of materials has nearly quadrupled—outpacing population growth. In 1972, as the Club of Rome’s report Limits to Growth was published, the world consumed 28.6 billion tonnes'
2. Abrupt climate change isn't the only reason we may consider ourselves in a terrible predicament. Extinction is escalating due to deforestation, logging, road-building, pollution..
Only system change action may limit the damage and/or protect us. Thread:
Today's economic system is taking us to 1.6°C-2°C by the 2030s with emissions now rising towards epic new extreme record highs compounding the extinction-ecosystem collapse crisis.
These tenths of a degree mean mass death, a truth which must be faced if we want effective action.
It's disheartening we're not facing the fact that 1.75°C-2.5°C, likely by the end of the 2040s, would mean billions of peoples' lives either turned upside down or taken from them without profound system change.
According to scientists, economic growth cannot prevent us exceeding somewhere between 1.6°C and 2.4°C of global warming by the 2040s, when a staggering 20% of species face extinction.
When you listen to the scientists, you realise economic system change is the only way. 🧵

'The most optimistic scenario has global temperature nudging past 1.5°C by mid-century but then dropping back by late century. Such a relatively short excursion above 1.5°C might not trigger the worst outcomes, according to the panel.'
US sanctions and extreme drought exacerbated by abrupt climate change are threatening 23 million people facing acute food insecurity in Afghanistan. 🧵

'There are 22.8 million Afghans facing acute food insecurity. By March, 8.7 million of those are expected to slide into critical levels of food insecurity'. news.un.org/en/story/2022/…

'22.8 million people will face "high levels of acute food insecurity." This is 55 percent of Afghanistan's population, the highest ever recorded in the country. An estimated one million children are suffering from "severe acute malnutrition" this year.'commondreams.org/views/2022/02/…
BREAKING: climate change since 1980 is nearly twice as bad as previously calculated 🧵
1.
From 1980 to 2019, the world warmed about 0.79°C. But taking energy from humidity into account, the world has warmed and moistened 1.48°C. And in the tropics, the warming was as much as 4°C.
To try to avoid total catastrophe will take total change.
The combination of rate & magnitude over the coming decades is unprecedented.
We must expect rates of warming, shifting rainfall and drought that will challenge the adaptive capacity of life on Earth including human beings.
Media won't make this clear.🧵
1.We must protect species and everybody. The current growth economy would take us to 1.6°C-3°C hell in the next 25 years if maintained. Fair, emergency system change required. Only by supporting independent media might the action-blocking silence be broken.climatecentral.org/news/ecosystem…
2. An ecological catastrophe.
Pollution, deforestation mostly due to animal agriculture, logging, mining, road-building, disease, industrial fishing, abrupt climate change, etc,..all causing rapid extinction.
