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 am not nearly old enough to see such drastic shange as you but even at 22 years old I have seen getting less and less snow each year as the time passes. When I was little we got at least 30-50cm of snow each winter. Not that much in the grand scheme but it was enough for everything to be snow covered and we used to build snowmen and igloos during the winter holidays. Our local lake used to freeze each winter and people would go out ice skating. It has not frozen more than once in the last 10 years. If we do get some snow it usually melts the same day because it changes from snowing to raining, or it just rains the next day. We had 1 day this year when snow was even falling and all the rest was just rain. We had rain on new years while I was able to go outside and rake the leaves last year while wearing nothing but a tshirt. I remember having 30cm of snow about 7 years ago on the same day so you can say it's quite a change. I used to get excited for winter but now it's just colder autumn with none of the nice colours.
