BREAKING: Earth's 8.7 million species call for immediate system change
60% of primate species are threatened with extinction, 75% are declining.
Main threat: habitat destruction due to logging/agriculture.
Hunting, road construction, oil & gas extraction, mining, pollution, disease, and climate change are also key threats. theconversation.com/60-of-primate-…
40-60% of tree species are threatened with extinction.
more than half of species are only found in one country, suggesting vulnerability to potential threats, such as deforestation from extreme weather events or human activity.
40% or more of plant species are threatened with extinction.
'this is just what we already know about. Researchers say there are huge gaps in our knowledge of plants, and more work is needed to assess the conservation status of more species.'beta.ctvnews.ca/national/clima…
40% of shark and ray species are threatened with extinction.
At least a quarter of the world’s estimated 8.7 million species might already be on the move, experts have warned, pushed out of their habitats by the changing climate and human activities.
'Our findings strongly suggest that where species can survive in nature is determined by the temperature at which males become sterile, not the lethal temperature.
..perhaps half of all species will be vulnerable to thermal infertility.'
Human society is yet to appreciate the implications of unprecedented species redistribution for life on Earth. Even if greenhouse gas emissions stopped today, responses required in human systems to adapt to the most serious effects would be massive. science.org/doi/10.1126/sc…
“Say there are 100 species [of fungi] that cycle carbon through a forest. Can we lose one of them? Ten of them? 50? 60? Maybe we can lose 99 of them. How many species can we afford to lose before we reach a tipping point, and we’re in some sort of trouble?”nationalgeographic.com/environment/ar…
Ecologists estimate that 15%- 37% of plant & animal species will go extinct as a direct result of the rapidly changing climate. But current models don't account for the complexities of impacted ecosystems so these extinction rates are likely underestimated.news.arizona.edu/story/climate-…
'34% of animals and 57% of plants' will lose over half their habitat by 2080 if temperatures rise 4°C
estimates are “probably conservative” as rising extreme weather, disease, and pests aren't accounted for in the study
'We have already observed impacts of climate change on agriculture. We have assessed the amount of climate change we can adapt to. There’s a lot we can’t adapt to even at 2C. At 4C the impacts are very high and we cannot adapt to them.' theconversation.com/ipcc-expert-wr…
It looks likely there's much we can't adapt to at 1.5/1.75°C (see 1.25°C impacts now).
We must try to limit the doom, protect species. The answers lie in the knowledge & wisdom of indigenous communities, not industrialised western 'civilzation'.
medium confidence that approximately 20-30% of species assessed so far are likely to be at increased risk of extinction if increases in global average warming exceed 1.5-2.5°C (relative to 1980-1999)
Intensive agriculture identified as the main driver for insect declines in Europe. Main culprits in other parts of the world: climate change & deforestation.
Non-climatic threats plus 1.6°C-2°C by the 2030s? Extinction hell.
'Ten to twenty percent of the world’s terrestrial bird species could be threatened with extinction by 2100 due to climate change and habitat destruction'.
'Even under the most optimistic scenarios, roughly 10 percent of parasite species will go extinct by 2070. In the most dire version of events, fully one-third of all parasites could vanish.
Economic growth continues to make global warming of 1.8°C - 2.4°C and rising by 2040 or so look unavoidable.
'Globally, the percentage of species at high risk of extinction will be 9%-14% at 1.5C, 10%-18% at 2C, 12%-29% at 3.0C..' carbonbrief.org/scientists-rea…
COLLAPSE/EXTINCTION: scientists fear global warming of 3.5°C, which wipes out 33-70% of species (IPCC AR4 2007, IPCC AR6 2022), will likely hit by the 2060s give or take a decade or two 🧵
1. IPCC scenario SSP3-7.0 shows 3.5°C by 2080 or from 2062 (not the worst-case scenario). Even a moderate emissions scenario can lead to 3.5°C this century (new research shows 2060s-80s possible).
2. A new pre-print from highly respected climate scientists implies 3.5°C by 2065-77 at current rates of warming. The authors warn this rate could increase or decrease perhaps suggesting 3.5°C by around 2055-2087 rather like IPCC high emissions scenarios. researchsquare.com/article/rs-607…
BREAKING: scientists say Earth's major systems are undergoing abrupt changes — and soon we'll all feel them 🧵
1. 'prepare for a future of abrupt change.. choices made now will determine whether we face a future of worsening impacts and irreversible change or one of managed resilience to the changes already locked in.' phys.org/news/2025-08-s…
2. Society must now brace for catastrophic impacts.
Destruction of habitats and wildlife has intensified and accelerated to an almost unimaginable degree during the capitalist era. Scientists say the 40-50% of plant species now facing extinction will be obliterated in a handful of decades. It didn't have to be like this. Rethink.
'previous mass extinctions.. took 10,000s, 100,000s, even millions of years to happen. this is happening so fast, now in just two, three decades..' google.com/amp/s/www.cbsn…
2. Current estimates of plant extinctions are, without a doubt, gross underestimates. Extinctions will surpass background rates by 1000s of times over the next 80 years. universityofcalifornia.edu/news/plants-ar…
BREAKING: as tropical forests show increasingly clear signs they are entering a collapse phase scientists warn irreversible mass extinction conditions are on the horizon 🧵
1. rapid warming & collapse
".. warming could continue to accelerate.. even if we reach zero human emissions. We will have fundamentally changed the carbon cycle in a way that can take geological timescales to recover, which has happened in Earth’s past.”scitechdaily.com/mass-extinctio…
2. “There will be a point in the not too distant future when we suddenly see and feel this mass extinction all around us very clearly”
“A key point of extinction crises is that life has always recovered.. However..we most likely won’t be there to see it."

With the ice sheet at “a tipping point of irreversible melting”, scientists currently expect an unavoidable sea level rise of 1-2 metres.weforum.org/stories/2025/0…
4 to 10 m sea level rise committed in the coming 2000 years, with the majoroty of that in the coming decades/centuries it would appear. science.org/doi/10.1126/sc…
BREAKING: horrific worst-case scenarios firmly back on the table as scientists confirm large-scale Earth systems such as forests, ice sheets, and ocean currents may already be collapsing 🧵
'large-scale Earth systems may be experiencing gradual collapses that are easy to miss, with profound implications
