Quite a few break down in water very rapidly. In any case, even those that take 6 months beats lasting forever.

What might be more expedient would be reinstate deposits on containers to encourage their proper deposit into recycling.

Is burning wood for power carbon-neutral? Not a chance
https://news.yahoo.com/op-ed-burning-wo ... 35561.html

The mammoth pandemic stimulus and spending bill Congress passed last week includes billions of dollars to expand solar, and wind energy. These are good measures to address greenhouse gas emissions. But the bill also contains a rider that would undercut those efforts.

A provision added to the bill, pushed for by Sen. Susan Collins (R-Maine), declares that cutting down trees and burning them for energy is carbon-neutral. This, of course, makes no sense. Burning wood will add to global warming — even if the wood replaces coal or natural gas, as scientific organizations and hundreds of scientists have long argued.

For decades, the wood industry has generated electricity and heat by burning wood wastes from harvesting and turning wood into paper and timber. Doing that makes sense because using the waste does not require cutting down more trees.

In recent years, however, there has been a bizarre but dangerous push to retrofit power plants and factories to burn wood. The European Union has spurred this effort by adopting laws to require more low-carbon renewable energy (which by themselves are good), but then simultaneously allowing wood to count as a carbon-free, renewable fuel. Countries in the EU responded by subsidizing power plants to burn wood. Utilities lobbied for this shift after realizing that their coal-fired power plants could stay in business if modified at public expense to mix in some use of wood.

But the process of burning wood results in more carbon being released into the atmosphere than burning coal. This happens in two ways. Trees in a forest store carbon and keep it out of the atmosphere. When trees are cut down, more than half the wood is left to rot or burned in producing a usable form of fuel (usually wood pellets), which releases carbon into the air. The wood fuel that is ultimately burned in power plants generates still more carbon. Overall, using wood produces two to three times as much carbon per kilowatt hour as burning coal or natural gas.

Now here is something that President Biden and I can agree on.

Not the lose of the jobs, But I have been against the Keystone pipeline from the beginning. This was not for the benefit of this country. CANADA wants their disgusting oil sand processed so they can sell it to anyone in the world. They won't build their own facilities so screw Canada. Yes it's going to be a big blow to their revenue and economy. :wink:

Biden ending Keystone pipeline would kill thousands of American jobs
TC Energy said project would sustain more than 11,000 jobs in 2021

https://www.foxbusiness.com/economy/ame ... l-pipeline

It is unclear how the Biden administration plans to address the job losses, but his $2 trillion clean energy infrastructure plan, with its goal of reaching net-zero emissions by 2050 at the latest, aims to "create millions of good-paying jobs that provide workers with the choice to join a union and bargain collectively with their employers," according to his website.

And by the way this net-zero emissions by 2050 is not going to get it.

We had a 15% reduction last year in emissions and reduced use of fossil fuel and it didn't make a dent in climate change

The reduction of fossil fuel is going to have to be curtailed severely to make a difference.

The American people are just going to have to suck it up and get rid of the internal combustion engine :roll:

That number was during the construction; once completed maybe 1-5% of that number of jobs.

Going to take many years of that reduction before you see significant change - nothing moves quickly

Or cows. :wink:

But I'd bet that there are means to capture, convert, and use CO2 that can be implemented that have not even started to see any real use.

I don't think the glaciers are going to wait for it.

Now and then: Iceland's vanishing glaciers
https://www.bbc.com/news/science-environment-55346329

The demise of glaciers around the world serves as a double whammy. Not only are regions losing vital sources of drinking water, and irrigation for agriculture, but the world is losing forever a valuable scientific history of the planet's climates.

They probably won't but I've not asked them either.

As with almost all things, we only think about what's going to happen in the short-term failing to think long-term while denying there's a problem that needed solving long ago.

INTERESTING

Cooling the planet by filtering excess carbon dioxide out of the air would require a new, massive global industry – what would it need to work?
https://www.bbc.com/future/article/2021 ... apture-co2

We have a climate change problem and it's caused by an excess of CO2. With direct air capture, you can remove any emission, anywhere, from any moment in time – Steve Oldham

The number of things that would have to happen without direct air capture are so stretching and multiple it's highly unlikely we can meet the Paris Agreements without it – Ajay Gambhir

If the world wants to avoid catastrophic climate change, switching to a carbon neutral society is not enough. The Intergovernmental Panel on Climate Change (IPCC) has warned that limiting global warming to 1.5C by 2100 will require technologies such as DAC for "large-scale deployment of carbon dioxide removal measures" – large-scale meaning many billions of tonnes, or gigatonnes, each year. Elon Musk recently pledged $100m (£72m) to develop carbon capture technologies, while companies such as Microsoft, United Airlines and ExxonMobil are making billion-dollar investments in the field.

It needs a use for the captured CO2 and products therein.

In a few years weapons manufacturers will find a use. Then it will become big budget money in the war machine.

Have you seen some of those 2019 photos of the massive changes in Iceland's glaciers ? Wow.

And this is why you are going to give up your internal combustion vehicles and get an electric or hydrogen powered one..

None of which will make any difference unless the production of electricity or hydrogen evolves beyond fossil fuels

I don’t have a viable answer. Off the wall answers i have. Lightning fast vegetation growth.ramped up hydroponic plant growth . A pipeline to outer space. Co2 powered pods . Traveling to Mars. Transporting tourists. Venting outside our atmosphere.

That I can see, but needs serious expansion.

Traveling to Mars. Transporting tourists.


Not following that at all

Venting outside our atmosphere.


Costly.

I was thinking that it could be catalytically converted to methanol and that that could be used as a feed stock for other materials.
