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.

Yep, next election will essentially be a carbon tax election. And so far it's looking like a clear conservative win, where "axe the tax" is the only policy given.

I've [tried] having discussions about the carbon tax on a fact-basis with my parents and they will not even acknowledge the carbon rebate as a thing that exists. Won't even look it up either, since their idea of the carbon tax being a general revenue tax that is funneled together with most other taxes and not refunded is such a simple, easier belief to have than to need to consider the merit of the program on factual grounds. Pretty quickly came to the conclusion that conversing with people who do this is pointless; they have their beliefs and do not want to acknowledge reality. It's too complicated and a simple view of ignorance is preferable.

It's not like there are no genuine points to be had against the carbon tax either.

  • It is charged before sales tax, making it not truly revenue neutral.
  • The existence of the carbon tax will cause a realized financial disadvantage for most Canadian families when considering the greater economic impact beyond simple tax paid vs rebate received (true despite 4 in 5 Canadians receiving more from the rebate than they pay in carbon tax).
  • Taxing the carbon emitted by home heating fuels is more problematic than other fuels like gasoline, etc, since families cannot reduce their carbon emissions from heating as easily; in most of Canada heating your home is a necessity for survival and switching to a less carbon-intensive energy source is a large undertaking.

All to say, there are some genuine discussions to be had on the merit of our carbon tax and the specifics as to how it is implemented. Those above points are not de facto hits against carbon tax, they are just points that can be debated in good faith.

Using the economic impact example; what is the economic impact of inaction. What alternative carbon emission reduction plan do you have that could work better? (Spoiler: >!They do not have one, it is repeal and not replace.!<) Carbon pricing has been evaluated time and time again to be the most effective way to reduce carbon emissions with the lowest economic impact.

Regarding home heating, (assuming a province going by the federal system) 10% of the carbon tax is going to programs to subsidize carbon reduction. This includes heat pump subsidies for low income families.

But, there are very few people who will even allow a discussion to progress to this point, as they do not even understand the program and would rather resort to a simplistic emotional response than acknowledge the program as it exists in reality.
