Worried about the Amazon burning?
Surely yes.
But what do you know of the S American Atlantic forest?
en.wikipedia.org/wiki/Atlantic_…
After hearing of the scorching heat over Paraguay, Brazil & Argentina, I called my dear friend Prof. Gustavo Zurita, former visitor @UFZ_de & @idiv.
I visited him twice in Puerto Iguazu, directly next to the amazing Iguazu waterfalls. (en.wikipedia.org/wiki/Iguazu_Fa…). These are set amindst 1 of 2 largest remnants of rainforest, 1 million ha of a forest that spanned 5000 km length & 1000 width. 87% of it is cut, the rest fragmented.
Yet the region has now just seen the worst drought ever, followed this year by already 3 months without rain and now 45C in SPRING. This is just the start! I asked if the forest has any chance to survive.
His reply was cristal clear: NO, the forest is doomed.
Prof. Zurita observes a sharp tipping point, with changes too rapid and drastic to be attributable to (global) climate change alone. Rather, we think it's related also to the Amazon & other regions being destroyed and burnt.
Why I am sharing this? Imagine that Earth's atmosphere has two main engines interacting: the hot and humid tropics at the centre, the Arctics at the ends. Global warming hits one engine, the slash-and-burn of rainforests switches off the second.
My interpretation is: jointly, through the consumption of the global north and the politics of Brazil, Indonesia etc., we are not only eradicating most habitats and organisms on Earth but also switching off the engines that drive Earth.

THREAD: When examining the (likely) CAP proposals of @EUParliament coalition-parties vs @EUCouncil, one can see much similarity in the systematic effort to empty the #futureofcap of a future. Yet if I need to choose who is worse, my verdict goes to…
1/x The EU Parliament who actually wins big scale in how anti-environment it is. But the @EUCouncil is winning in their direct assault on small farmers (who happen to be the majority). Here's why.
2/x Both Parliament & Council try to empty GAEC 9 of contents: set low level of landscape features, limit to arable land (-40% UAA) & add production. Why? Because interests to maximise short-term production overrule evidence of the long-term insurance-value of these features.

1/7 Thread: the @EUCouncil proposal for the CAP (data.consilium.europa.eu/doc/document/S…) regarding GAEC 9 bears two conceptual flaws. First, non-production areas were proven valuable for both biodiversity and ecosystem services, while production-oriented areas like catch crops, are ineffective.
2/7 Second, catch crops and N-fixing crops are not landscape features. A proposal for accepting merely 3% “landscape features” is far under current cover of such features, as demonstrated by their rapid and still ongoing declines.
3/7 Evidence also shows that the inclusion of prodution options in Greening has been the key factor leading to the failure of EFAs and, de facto, the end of the Greening attempt, for a simple reason: if farmers can choose production-oriented but ineffective options, they do.

1/x Out now in @oneearth: Comment with @SebastianLakner
cell.com/one-earth/full… referring to a new paper by Scown et al. indicating just how essential and urgent is a substantial CAP-reform (thread). doi.org/10.1016/j.onee…
2/x Scown et al. offer robust, data-driven analyses indicating how justified the CAP-critique is. Over 24 bn. EUR are spent in EU regions with above-average farm income & regions with high GHG emissions, whereas biodiversity-rich areas, receive insufficient support.
3/x The distribution of CAP Payments, on the farm and regional levels, are unlikely to revert inequalities in the farming sector and can even worsen them, in conflict with the income objective of the CAP and the UN’s #SDGs 10 (Reduce Inequalities).
