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.

none of this addresses my question:

CAN YOU PROVE THAT 2-3% OF THE POPULATION BOTH HAVE VOTED FOR GREENS, BUT OTHERWISE WOULD HAVE VOTED FOR DEMOCRATS.

i already know the answer: you can't prove a counterfactual.

A good way to is poll twice, once including a Green Party Candidate, and once not. Emerson College did that for some swing states a few weeks back. Here's a pretty typical example, showing how results in Michigan change when West is added to the ballot:

This is why having him on the ballot is a really damaging for the Democrats, and it's important that there be a negotiated policy concession to get him to avoid the damage.

what makes you think this is a good method for proving your claim that 2-3% of all voters were democrat voters who switched to green in past elections?

You are being so rude. Silence is linking all the data and graphs at you and you're spitting in their face.

none of the data or graphs are proof that 2-3% of voters have voted green but would have otherwise voted democrat. demanding proof for a claim isn't rude.
