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.

Better 3 seconds than 0. We need everything we can to fight climate change if we are even going to have a chance of mitigating the damage.

Net negative likely. How much CO2 was emitted to create this plant?

I have a way to do this but it would require people to plant trees.

25kg per year, per tree. Let's plant these "trees" everywhere.

If every one of the 20 some million adult Canadians planted a tree once a week for say 10 weeks a year, just imagine. 20 million x 10 x 25kg sequestered a year later and you get additional benefits. No need to change your lifestyle, just plant on on the fringe of grass by the Walmart parking spot, drop on in by your workplace, etc. Golf courses: sorry we need trees, your lifestyle will change sooner rather than later anyway golf course user.

Edit: 5 million metric tonnes, I think.

And, hey, why not pay young people to do this? You get a tray of trees in the morning. Sign into your app, document each tree. In addition to planting the app sends you to previous locations others planted trees at to verify the tree is there.

5 million tonnes.

But then if 4000 tonnes is equal to reversing 3s worth of emissions, 5 million tonnes would still only be 3750s, or just over 1 hour.

Yup, not awesome but you do it year after year. It might help raise consciousness. But, yes, ultimately a drop in the bucket.
