1/6 Our 🌎 is heating and losing crucial carbon sinks. (Look at the #Amazon!)

🌳Tackling climate change means decarbonizing the economy but also recarbonizing our ecosystems
🦥I'm looking at the role of mammals in this task

But wait, mammals absorb CO2?⬇️
#DICECON21 #ConEffect
2/6 Well no *but* they mediate carbon flux:

Grazing by🦌🦘can stimulate🌿growth (more CO2 absorbed). Too much grazing does the opposite!

🐺🦁 influence plant growth by keeping 🦌 in check.
Meanwhile🐰 can ⬆️ soil carbon by digging. So much going on!

#DICECON21 #ConEffect
3/6 Mammal functions are so complex #climate scientists are ignoring them in #carbonbudget relying on 🛰️ images of 🌍vegetation.

But their role matters: by some estimates 🐺control of 🦌in North America could offset emissions of up to 20mn 🚗/year!

#DICECON21 #ConEffect
4/6 Too bad humans don't like 🐺!

Anyway, my project is an #evidencesynthesis: I comb through papers on how mammals in 🌲🌳 and grasslands influence carbon sink capacities. The result is an #evidencemap of where the knowledge lies on the subject.

#DICECON21 #ConEffect
5/6 (that 📊is a subset of papers)

#SystematicMaps help👀research bias, locate evidence that has fallen through the cracks & form policy.

This is important as we look for #NatureBasedSolutions to #ClimateCrisis and make sure #rewilding is evidence-based.

#DICECON21 #ConEffect
6/6 Thanks to @CharlieJGardner for supervising and a shoutout to @EnvEvidence, and their #ESTraining resources on methods of #evidencesynthesis and dealing with 1000s of papers without having a heart attack!

#DICECON21 #ConEffect
Thanks @MattLinkie for moderating and #DICECON21 organisers!

A hospital near Moscow mixed up two patients, one of them died and his body handed over to the wrong family who buried him only to found out their real grandpa was alive. But because his only document is a death certificate he can't leave the hospital.
Seeing this went viral, a couple more anecdotal details: when the family was picking up the (wrong) corpse, they actually said, this is not our grandpa. But hospital staff convinced them, saying the facial bones shift after death.
The body was buried at the family plot, under the wrong name. Now it needs to be exhumed, but the dead man's actual family is not particularly interested in this body. The hospital meanwhile is saying, just leave the corpse be, why go through all this hassle?

My first story from Yakutia, with great pictures by @AFPMladen. Troubling times for people living in Soviet-era houses built on permafrost without climate change in mind. news.yahoo.com/siberian-regio…
This is how people study permafrost in the Permafrost Institute's freezing underground lab: they cut the permafrost cylinders like sausage.
And these structures that look like anti-tank obstacles are called "seasonal cooling installations". Freon or Kerosene in the part above ground cools in the winter and drops below surface in condensed form to keep the permafrost solid.
