💻 Modeling permafrost change allows us to predict and preview the future Arctic. So how do #PermafrostPathways and other scientists make these predictions?

🌍 Day 1 of the Hybrid Terrestrial Ecosystem Modeling Workshop 2024 is off to an inspiring start! Engaging presentation on #Permafrost and the #CarbonCycle. @WoodwellArctic @ArcticBiology 🌱🔬
New work: Permafrost carbon emissions need to be accurately projected in Earth System models for full consideration of the remaining global carbon budget nature.com/articles/s41558-0…

How much is spring green-up and fall green-down impacted by warmer temperatures? How well can models predict spring green-up and autumn green-down? Find out in our new publication onlinelibrary.wiley.com/doi/…@koen_hufkens@EcossNau
and others
Up to 30 days longer active growing season in the warmest enclosures at the #SPRUCE experiment if you add up earlier spring green-up and delayed fall senescence
The strongest driver for autumn green-down is the accumulation of chilling degree days (CDD) and models including a CO2 parameter do best. Increased atmospheric CO2 advances autumn green-down #ClimateChange
🚨🌍 Global Carbon Budget 2022, out now!🌍🚨
It provides the latest update on how we humans have tampered with Earth's remarkable system of #carbon stocks and flows.
So what are the take-homes from our latest update?

New permafrost carbon synthesis paper with 9 future worlds of Arctic methane and carbon dioxide emissions. This accelerating feedback to climate change depends on what humans do and the response of Arctic ecosystems to warming:

Myth 1: The fuse is already lit, and massive meltdown and #GreenhouseGas release are inevitable within a few years or decades. Abrupt methane release from hydrates, craters, and lakes has been triggered and is now unstoppable ⏰⌛️
What is the best single thing we can do to protect permafrost ecosystems? Stop fossil fuel emissions! New pub is out addressing the urgency frontiersin.org/articles/10.…
Seeing #permafrost, feeling how cold it is and standing next to a massive ice wedge is an amazing experience (so is the smell of decomposing organic material!). Thanks @Thomas_Douglas for the great tour
