Is the message from scientists "we need zero emissions by 2028 or so because of feedbacks and then climate change must be reversed somehow but geoengineering presents a danger to all life on Earth and carbon-sucking technology at scale is a fantasy"?

“If rapid emission reductions are initiated soon, it is still possible that at least a large fraction of required CO2 extraction can be achieved via relatively natural agricultural and forestry practices with other benefits,” the authors wrote.
“On the other hand, if large fossil fuel emissions are allowed to continue, the scale and cost of industrial CO2 extraction, occurring in conjunction with a deteriorating climate with growing economic effects, may become unmanageable."
'1.5 degree C and 2 degree C temperature targets.. "are far above the Holocene temperature range.. If such temperature levels are allowed to long exist they will spur ‘slow’ amplifying feedbacks, which may have potential to run out of humanity’s control."
To achieve negative emissions the study recommends using forestry and agricultural practices that increase the carbon-sucking ability of soil and trees.. Even if that’s achieved, more expensive and intensive methods for emissions extraction would be needed'insideclimatenews.org/news/06102016/…
"We assume that improved practices will aim at optimizing agricultural and forest carbon uptake via relatively natural approaches.. In contrast, proposed technological extraction and storage of CO2 does not have co-benefits and remains unproven at.. scale.”insideclimatenews.org/news/06102016/…
5 years on and no action has been taken.
The combination of abrupt climate change, habitat destruction, and pollution looks more and more like a predicament to me, with positive actions still possible but no 'solutions' in sight.
The global economic system is waging a war on nature.
'And 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.'
What newspapers still won't scream about is when Earth system feedbacks like thawing permafrost are taken into account, emissions must be slashed to zero in the 2020s for any hope of a reasonable chance of staying below potentially totally catastrophic levels of global warming.

Carbon 'budgets' for horrific 1.5-1.9°C of global warming are either tiny or non-existent according to climate scientists (nature.com/articles/s4324…) rven without the latest science on Arctic feedback loops being taken into account.

'The tropics could become uninhabitable if we don’t limit global warming to less than 1.5°C.'
Above this, the equatorial region, which is home to around 43% of the world’s population, could see air temperatures increase beyond what humans can stand.
'Germany's coal exit plan [by 2038] falls far short of environmental recommendations. According to estimates, the European Union needs to phase out coal by 2030 to meet the 1.5C target of the Paris Agreement'
1. The tropics contain over 75% of all Earth's species
2. Scientists expect 1.5°C of global warming by 2030
3. Deforestation, mining, road building & pesticides also threaten the tropics
It will never be too late to try to limit the damage & protect everybody.
How many people now strongly suspect capitalism is a threat not just to organised human society but to all species?
Scientists expect 1.5°C by 2026-2032, but with emergency, climate justice, degrowth, economic-system-change action it could yet be delayed.newscientist.com/article/227035…
'The tropics contain.. more than three-quarters of all species.. actions are urgently required to prevent a collapse of tropical biodiversity'.
Did you know the tropics seem set to start becoming uninhabitable from as early as 2026 with the majority of Earth's species facing a struggle for survival in extreme conditions as ecosystems collapse due to habitat destruction & climate change during capitalism? Rise up now, etc
'The tropics could become uninhabitable if we don’t limit global warming to less than 1.5°C'.
Scientists expect 1.5°C to hit by 2026-2032, but with emergency, climate justice, degrowth, economic system change action it could yet be delayed. Organise now.
The tropics contain the majority of Earth’s biodiversity: their terrestrial, freshwater and marine ecosystems hold >75% of all species. Concerted local, national and international actions are urgently required to prevent a collapse of tropical biodiversity.nature.com/articles/s4158…
emissions must peak-&-plummet now
deforestation must stop now
plastic overproduction must stop now
pesticide use must stop now
industrial fishing must stop now
industrial agriculture must stop now
soil destruction must stop now
Extraordinary change is coming.

Slash emissions to zero by 2025-30 while it's still too late.
