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 would say definitely less snow in the US North-East than "back in my day", but certainly more storms/weird weather. Like we are supposed to have possibly 70mph wind gusts tomorrow with snow/sleet/rain all in a 24hr period of time.

We live on Lake Diefenbaker, in southern Saskatchewan. I used to do a lot of snowshoeing right out our front door. It's been a decade since I've seen enough snowpack to head out anywhere other than on the lake itself. Even then, I would probably be better served with ice grips of some kind on my boots instead of wearing my snowshoes.

Contrast that with when I was growing up in the 1960s. We sometimes had enough snow by Halloween for building snow forts and running skidoos.

Right now, as I write this, we are having our first proper winter day, at least as far as temperature is concerned (-21C at noon). We don't even have enough snow to hide the grass and we're supposedly in line for a lousy 5 cm tomorrow. I'm not holding my breath, because every snowfall forecast of the season has overestimated both likelihood and amount. (In fact forecasting is all screwed up in general. I think the meteorological models have lost much of their relevance.)

Yeah, I have noticed the bay on the lake (a great lake) doesn't freeze as early or as much anymore, and may not even this year by the way things are going. I also think the models are really off because the weather is just so unpredictable even to a computer. And a small change in one place has a ripple effect, just like the extinction (or removal) of an animal can change a whole ecosystem [watch any of the documentaries on the wolves in Yellowstone as a perfect example].

We haven’t had very many storms in New England this winter. The last big storms in a row, were back in 2013-15 and they were still late February storms. Our first plowable storm was Sunday, and we’re scheduled for 2-3 inches of rain tonight.

I used to work in the ski industry, but it was already a low paying job, when the season starts 1+ months later and ends sooner, it’s barely worth the gas money to get there.
