Climate - truthful information about climate, related activism and politics.
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.
I still worry that even if DAC becomes really efficient and cost effective, it will only encourage large corps to pollute more. They will claim that since the emissions are removed anyway, they can keep pumping CO2 into the atmosphere without consequence.
I worry more that it will become like recycling, and they'll pretend it works or that it's being done at scale so the majority stops worrying about it
"[...] COF-999, is a microscopic scaffolding of hydrocarbons held together by superstrong carbon-nitrogen and carbon-carbon bonds, such as those found in diamonds. The amines sit in the scaffolding’s open spaces, ready to snag CO2 molecules passing by"
This is great news!
Until it causes cancer!
Cancer kills humans, which are a main cause of CO2 emissions!
