Earth system feedbacks are very complex - there are positive but also negative feedbacks; tipping points that are subject not just to thresholds but the rate of change. Our new paper reveals some of that complexity with respect to the composition of peat vegetation:

In July, the Pacific Decadal Oscillation hit its lowest monthly value in **171 years** of data. The current string of negative readings is the longest on record.
How does this related to major research just out on climate change and prolonged SW US drought? 1/4

[FOUNDER'S BRIEF - @rhettayersbutler.bsky.social]
They are not yet gone. But for thousands of species, the Earth is already holding its breath.
A new review confirms what conservationists have long suspected: more than 10,000 species now sit on the precipice.
๐ Are protected areas ready for climate change?
As ecosystems shift, scientists urge a rapid shift to โclimate-smartโ conservation. New efforts like the CAPA initiative aim to climate-proof PAs in Africa, Fiji & Belize.

๐Over time, #restored #peatlands tend to align more closely with intact sites, exhibiting a linear trend in #LST and albedo similarity. Full alignment may take decades.
What did we find?
โก๏ธRestoration led to notable shifts in the difference between #restored and intact #peatlands.
โก๏ธDaytime #LST differences decreased.
โก๏ธNighttime #LST differences changed.
โก๏ธAlbedo differences narrowed, especially in winter & early spring.
We assessed 72 sites across #Finland, #Estonia, #Latvia, #Lithuania, the #UnitedKingdom, #Canada, and the #UnitedStates.
Before restoration, degraded sites often had lower daytime land surface temperature (LST), higher nighttime #LST, and lower #albedo than intact sites.
New paper out! Using over 20 years of #satellite data, we show that restored #peatlands start to resemble intact peatlands. Their #albedo and land surface #temperature (LST) gradually align with those of natural peatlands.
