🌍🔍Peatlands of Canada's West Coast: A carbon store 3x larger than the regions rainforests. But: depth and extend are barely researched. 👉 Prof. @JürgenKreyling & @hanna-martens.bsky.social sky.social of @greifswaldmoor.bsky.social & @unigreifswald.bsky.social want to change that.

www.cbc.ca/news/science... Glad to see this topic at the top of CBC News - watching fires burn up the boreal year after year sucks, and it's the peatlands burning that I worry about most

Wildfires send Canada's carbon emissions soaring. And our peatlands emit even more | CBC News
A new government model to estimate peatland emissions and their impact on climate change could provide a new perspective on the problem — and spark new discussions about solutions.

Also, I would bring up the complete destruction of peatlands for mining, especially for oil and gas but in the future, maybe also rare minerals (Hudson's Bay Lowlands). While I research agriculturally drained peatlands now, oil and gas destruction hits close to home www.pnas.org/doi/10.1073/...

Thanks @hankgreen.bsky.social, it's so true! Why are we not all talking about how important peatlands are?! Globally, drained peatlands emit 5% of annual greenhouse gas emissions. Wet peatlands are the best carbon capture system out there!

Months of report writing has me reminiscing about all the cool peatlands I saw last summer while doing field work in northern BC, Canada. My favorite was definitely the quaking fen! It did though require a rescue from a thankfully nearby colleague after I fell in to my waist. 😅
Wetland complex from the air, with upland aspen forest transitioning to fen with increasingly stunted trees and then to open water.Quaking fen dominated by herbaceous species and some very stunted larch trees.Bog with sphagnum hummocks, labrador tea, and stunted black spruce.
