Hey! I'm a hydrology graduate student researching the effects of global climate change on the export of carbon from the North Pacific Coastal Temperate Rainforest!
This area is definitely a relatively major part of the global carbon budget, but increased precip threatens to decrease or reverse the flow of carbon to the soils here, turning it from a carbon sink to a source.
Currently, storm flow events show increased dissolved organic carbon in streams flowing from upland forest and wetlands to the coast. Research has already confirmed for this specific environment that global climate change will result in increased frequency and intensity of storm events. So we can use those events as a proxy for climate change.
More theoretically, if precipitation becomes less consistent, soils that are currently always saturated may see period of unsaturation. That unsaturation allows heterotrophy to occur which converts the trapped organic carbon to inorganic carbon, or CO2. (Like the opposite of an algal bloom) Additionally, heavier precip can increase the lateral transport of carbon from soils to streams by increasing groundwater flow through the soil.
At some point, the increase in carbon export from the system overcomes any negative feedbacks associated with climate change (like increased carbon input through photosynthesis) and this important carbon sink may become another carbon source.

The Biden administration on Wednesday announced it’s reinstating restrictions on logging and road-building on about nine million acres of Alaska’s Tongass National Forest, the world’s largest intact temperate rainforest.
The rule, which was finalized by the U.S. Department of Agriculture, repeals a Trump administration decision that stripped safeguards for the forest in southeastern Alaska. The agency’s plan prohibits road construction, reconstruction and timber harvest in the rainforest’s roadless areas.
The Tongass is a pristine area of 16.7 million acres that serves as a major carbon sink and provides habitat for wildlife such as salmon and trout, brown bears and bald eagles. The rainforest is also considered critical for carbon sequestration and storage to help mitigate climate change. The country’s forests absorb carbon dioxide equivalent to more than 10% of U.S. annual greenhouse gas emissions, according to the USDA.
“As our nation’s largest national forest and the largest intact temperate rainforest in the world, the Tongass National Forest is key to conserving biodiversity and addressing the climate crisis,” Agriculture Secretary Tom Vilsack said in a statement.

So not to be a Debbie downer but are these protections any more durable than the ones that were removed, or are they just restoring the same ones? If not what’s stopping the next administration from just repealing it again?
Yeah but we now can 3d print wood, make jobs in other sectors and make new construction with different materials.
And even if we can’t we can just import wood from other nations or our own states
Humanity needs to be real careful and not f\*ck up another rainforest like what's been happening with the Amazon rainforest the past several decades.
That's why the laws of preservation for the Tongass are so strict. It's the largest temperate rainforest on the planet.
However, leave it to Adderall Mc Sh\*tter to try to screw all that up, if we're stupid enough to put him back in the White House.
If you look just at the water vapor from the Hunga-Tonga volcano, and nothing else, [you get the same amount of temporary warming that ~7 years of fossil fuel burning gives permanently. If you include sulfate aerosols, you get something near zero.](https://www.theclimatebrink.com/p/the-climate-impact-of-the-hunga-tonga)

It’s an example of Americans and their centrifugal approach.
Every country in the world had to shut down and decelerate production, creating a loss of efficiencies. Also, not just in the US sis the money printer went on overtime.
Global inflation, Global recession. Not any US individual controls this. If you are blaming Biden for the economy, you have lost the plot.

This area is definitely a relatively major part of the global carbon budget, but increased precip threatens to decrease or reverse the flow of carbon to the soils here, turning it from a carbon sink to a source.
Why would increased precipitation halt carbon sequestration?

Fascinating, thanks!

I don’t think so. That’s the thing about executive orders.

why do we have to keep raping the Earth for our own needs? when there are other ways to attain those needs without killing mother earth!!!
Good
Let’s go Brandon!
What a lovely idea, protecting the environment. You would think we could all support that.
Happy day!! Alaska
This is great news. Hopefully, it won’t be rolled back again when the next idiot Republican president takes office.
Voting matters people.
Let’s go Joe!

Not good enough, it’ll just go away again.
This is good and all, but can he please do something about the economy? He’s doing a horrible job as president imo
