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: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

This is no suprise.

Reality is most Canadians don't care about C02. We almost gave away our sovereignty over a levy designed to save us money.

I mean the name "Tar Sands" just sounded so clean and green though!?

Maybe we could try ‘carbon keeping’ or ‘carbon never releasing’ where we keep the carbon that is currently buried underground buried underground instead of digging it up and releasing it into the atmosphere. I will try to come up with a flashier name.

I think a better idea would be to start selling carbon futures based on subprime coal mine loans. Create a big fraud bubble where a bunch of coal is supposed to exist mined out of the ground that doesn't.

Operation Carbon Cloud we can call it.

Okay I was skeptical until I got to the name but now I’m fully on board and ready to invest some negative numbers. Can we call our ‘novel debt vehicle’ Carbon Collateralization?

“Operation Carbon Cloud harnesses the power of carbon collateralization to allow shrewd investors to leverage natural carbon capture into HUGE negative numbers

According to the prime minister’s former Chief of Staff Marco Mendicino, climate has always been a secondary concern. A key goal for the Carney government, Mendicino explained at a Toronto conference in January, is “to increase our oil production.”

Sad.
