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.

I don't know anymore.. I'm more confused about the severity of climate change as time goes on.

Climate change is not a big deal if the life a person is expecting to live is only a slightly more stressful version of a life without climate change (I think this is where we are currently). It is a big deal if it has the same degree of impact of that a mental health disorder might have - work, relationships, and overall lifestyle are significantly impacted and that person needs to make major adjustments to learn to live with it. I don't see a middle ground here, but I'm also not thinking that hard about it.

I don't know where we are going. And yes... I know the world is a big place and some people are going to feel the worst aspects, but to keep things simple (and relevant) I'm only thinking of other "middle" class Canadians living in large urban centers. If this argument takes into account every person on earth then the answer is just going to be a meaningless 'yes'.

Edit: I'm eager to hear from people about this. If you have something to say please share.

I don't know where we are going.

Famine, war, collapse of civilisation, rise of warlords, loss of knowledge. Everywhere. Within our lifetimes.

Just look at the first of those and the rest follow. Think about how likely it is that our civilisation will be able to grow crops in the quantity it has up until recently, even five years from now, given the increased frequency and severity of extreme climate events.

That's what I find confusing. We (global we) have already had enormous crop failures and disasters recently. https://www.agweb.com/news/crops/crop-production/farm-bureau-finds-2022-weather-disasters-amounted-21-billion-crop-losses these events can get amplified on social media and then it's disorientating to me when the effects slip away.

I think what I want is data:

https://ourworldindata.org/agricultural-production

I don't doubt it's going to get worse, but I'm struggling to understand the details of that. You're saying famine in Chicago, full on North Korean style society? War, yes I said already we already do that all the time. Not new. Warlords, not new. Loss of knowledge? Vague. I'm sorry but this is what I'm talking about. How did you reach these conclusions, if you know?
