Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
This is what bothers critics of carbon capture [...].
Far from the only thing that bothers critics, the part where CC results in more CO2 output for all the energy it needs is usually the first thing mentioned. Even if you run CC 100% on renewables, you would still be better of replacing fossil fuels in use elsewhere with renewables then using renewables on CC.
This.
Until the entire world runs on renewables and nuclear power it doesn't make any sense at all to do carbon capture as the energy used to capture would have been more efficiently spent on avoiding carbon release in the first place.
Been saying this for years here but it usually ends with a lot of downvotes
Indeed, generally one stops the spill before starting clean-up.
You're right of course, but the nuance is that research takes time. We need to start working on it now so we will be ready to scale the technology when we have surplus renewable energy. It's a tricky balance.
Oh for sure, research on the topic is great, I'm just dumping on these stupid tech startups that claim they'll fix climate change by sucking up all carbon.
No you won't.
the part where CC results in more CO2 output for all the energy it needs is usually the first thing mentioned.
If you're doing CC from air then yes but if you are using something like Exxon's CFZ technology then maybe not. CFZ is used on the production side to remove the "sour" stuff (like CO2) from natural gas before its burned.
BTW ExxonMobile built that CFZ plant in LaBarge, Wyoming and it's been operating for over a decade and its now being expanded.
Let me guess, the future political fights will be democrats passing regulations that you can’t be leaning. And republicans arguing that this will kill profits.
While potentially true issues, I notice detractors have never and continue to not be concerned that the natural gas and oil pipelines in the Midwest have the same issues with greater risks...
