House Republicans are searching for solutions to climate change without restricting American-produced energy that comes from burning oil, coal and gas.
Large-scale tree planting can remove some CO2 from the atmosphere, but nowhere near as much as humans add by extracting and burning fossil fuels. See https://skepticalscience.com/1-trillion-trees-impact.html for a detailed assessment of what this looks like.
Teach young people life skills, lift a whole generation out of poverty, plant and manage forests, fix up our infrastructure... So much could be done. A modern, environment-focused CCC would be revolutionary, and I would bet whoever runs with some form of that idea first sweeps the following elections.
It was proposed as part of the Green New Deal but hasn't been able to meaningful funding through the Senate. Too many Republicans working with a handful of bought-off Democrats
We actually had that through the VISTA and Americorps programs in the 90s and early 2000s (I believe Americorps is still around). I was a volunteer for VISTA in 2003, just as the Bush Administration shredded the program. They signed us up on the promise that our student loans would have their payments covered while we volunteered, then refused to deliver for six months. It wasn't until then Senator Hillary Clinton got involved that they reversed their decision, and by that time I and half the class were forced by financial reasons to drop out of the program. The living stipend they gave us was only $740 a month, and we were forbidden to take outside jobs. Throw student loan payments on top of that and there was no way to survive.
The Bush admin knew this, and they continued to dismantle the program, using the disastrous drop-out rates of the class of 2003 as an excuse for further cuts. VISTA is now gone, and with it the specific part of Americorps that was focused on poverty relief.
The reason we don't have these programs anymore is because the conservatives have deliberately dismantled them, not because the left hasn't tried again and again to use government towards building real value in our society.
I've been saying this for years. It never should have stopped but the Republicans are hell bent on destroying anything good that the government can do for us.
There was a post the other day about how painting rooftops white could reduce temperatures, with a small handful of people saying they'd "consider it when their roof needed replacing".
The only way that idea would have an impact is if there were strong regulations and incentives backing it to encourage widespread adoption.
The only way we'd ever get those regulations from a neoliberal politician is if they had shares in a white paint company.
I think many Republicans have always had the opinion of "we will just fix it when or if it becomes a problem", despite the fact that most studies (and common sense) has shown that it will be harder and harder (and more expensive) the longer we wait, or possibly not fixable at all.
So to answer your question: No, they have no fucking clue how long it will take or how much it will cost to plant 1 trillion trees.
It would take much longer for the trees to become effective carbon capture utilities than the destruction caused by coal mines and fossil fuels the Rs would likely push alongside their newfound climate wisdom.
Trees are expensive, and planting trees means you can hire workers to perform back breaking work for little pay. It's surprising that republicans are just now realizing that they can grift this to hell and back.
You can do it multiple times and take cuttings to grow new trees.
I dont know how much land a pig farm needs, but if it's like chicken factories, they basically live in cramped spaces. So you can dump the biochar into the pig shit. Let it soak up the nutrients and then fertilize the stumps.
The biochar is now stable carbon that will be sequestered in the ground for hundreds of years
I have been planting hybrid poplars and willows for three years. I'm bad at it, and lazy. So I basically just walk out to the semi-swamp behind my house and push sticks in the ground. I now have about 15 trees, 8ft to 26ft, and I'm slowly turning my backyard into a shady alcove.
Unfortunately the hybrid poplar only lives for 30 years, but you can plant longer living trees (maples, pines, oaks) while the initial batch is growing. Then bury the wood of the poplars to sequester the carbon.
