"Arctic Climate Collapse! This time it's REALLY flipped!!" - Just have a Think

https://piefed.social/post/494096

Finnish forests are shifting from carbon sink to carbon source.

New studies show they’re now emitting more CO₂ than they absorb. Why? Climate change, land use, and ecosystem shifts may be key factors.

What does this mean for carbon neutrality goals? Can better monitoring and policy interventions help?

#FYI #PaulBeckwith video lecture and literature review

"Instead of being a strong sink of carbon, pulling vast amounts of CO2 out of the atmosphere, a large chunk of the Arctic region is no longer doing this. Instead, it has become a source of carbon (CO2) which is very concerning."

A third of the Arctic’s vast #CarbonSink now a source of #emissions, study reveals

"For millennia, #Arctic land ecosystems have acted as a deep-freeze for the planet’s carbon, holding vast amounts of potential emissions in the permafrost. But ecosystems in the region are increasingly becoming a contributor to global heating as they release more CO2 into the atmosphere with rising temperatures."

Well that's a bit of a bummer.

Concerning productivity of US Forests : Hoagan et al. found that
"adverse effects of climate change appear to overwhelm any positive drivers in the water-limited forests of the western United States, whereas forest maturation and positive responses to age-independent drivers contribute to eastern US carbon sinks."
This highlights the vulnerability of the #Forests #CarbonSink to #ClimateChange
And what are the predictions for the Eastern #USA in terms of precipitations ?

Analysis of carbon emissions from 2023 Canadian wildfires: “We find that the magnitude of the carbon emissions is 647 TgC (570–727 TgC), comparable to the annual fossil fuel emissions of large nations, with only India, China and the USA releasing more carbon per year. .. concerns about the long-term durability of these forests as a carbon sink.”

Logging Native Forests in Victoria to end by 1 January 2024, saving 14 million tonnes of carbon by 2030, ensuring Melbourne's water quality, reducing bushfire threat, ensuring endangered species habitat.

Announced today by Premier Dan Andrews as part of Victorian budget. Brings the end to logging target forward from 2030 to 2024.

Native forest Logging in NSW: Stopping native forest logging in NSW could create $100 million in climate-related benefits annually, according to a new report released last week by Dr Jen Sanger, compared to the $9 million the industry cost taxpayers in 2022.

Read the linked report, but the news article gives an excellent rundown on NSW logging as well as previous reports on Native logging in Victoria and Tasmania and carbon emissions from logging. The report argues that Plantations are a climate Friendly alternative to native forest logging.

Just finished skim reading this study on urban lawns and grasslands soil carbon sequestration. It is an important meta-analysis contributing to addressing urban climate emissions.

"High soil carbon sequestration rates persist several decades in turfgrass systems: A meta-analysis." (OpenAccess)

I did a fair amount of reading on Soil Organic Carbon from turf grasses when I researched my literature review on Synthetic Turf in 2021, and this article pulls a lot of information from numerous studies together..

Vegetation in built up areas of cities are responsible for a surprisingly substantial take up of city CO2 emissions, researchers have found, looking at the biogenic CO2 flux in greater New York. Up to 40% of anthropogenic emissions during summer days may be sequested in New York, which has a tree canopy coverage of about 22%, and grasses (lawns) another 12% of the area.

Provides reason for further enhancing urban greenery and urban forests as part solution to the #ClimateCrisis.

Lead author Dandan Wei said "This tells us that the ecosystem matters in New York City, and if it matters here, it probably matters everywhere else.”

So Slarty Bartfast, Douglas Adams 'HichHikers Guide to the Galaxy' original Earth designer with a particular penchant for designing fjords, must have known something. He did his job well.

Fjords act as global temperature regulators, being carbon sinks during interglacial periods and become carbon sources during glacial periods.

Fjords, small in size and number, are significant carbon reservoirs
https://www.sciencedaily.com/releases/2022/12/221208114757.htm
Fjords comprise a mere 0.1 percent of the surface area of the ocean yet store a whopping 11-12 percent of the carbon stored in the ocean. New research shows they sock away 18 million tons of carbon during interglacial periods, like the one we're in now.

Study: Whales in the carbon cycle: can recovery remove carbon dioxide? https://www.cell.com/trends/ecology-evolution/fulltext/S0169-5347(22)00279-8
Short Answer: Yes it can

"Their size and longevity allow whales to exert strong effects on the carbon cycle by storing carbon more effectively than small animals, ingesting extreme quantities of prey, and producing large volumes of waste products," write the authors. "Considering that baleen whales have some of the longest migrations on the planet, they potentially influence nutrient dynamics and carbon cycling over ocean-basin scales."

"Whale recovery has the potential for long-term self-sustained enhancement of the ocean carbon sink," the authors write. "The full carbon dioxide reduction role of great whales (and other organisms) will only be realized through robust conservation and management interventions that directly promote population increases."
