It’s winter in Antarctica, when sea ice cover typically grows. But this year’s sea ice is way behind, reaching record lows with implications for the planet.

      There isn’t any reason to expect near-term human extinction due to climate change.

      The continuation of warming is also a human decision. One we can change.

        I get the necessity to spread a message of hope, I really do. If people start to see the cause as truly lost, the motivation to change any behavior will go down even more.

        However, in these times, I find it harder and harder to keep a positive mindset about this. And I am sure I’m not the only one.

        how? Like lets say we need to get on the track of reversing the course of climate change right now, within the next 10 years at most. What is the most effective thing a nobody like me can do about it?

          • Talk with people about it, to help build the political will for action
          • Get involved in a political campaign, with volunteer hours or money. In the US you’d find volunteer opportunities here and can give either to the Biden Victory Fund or a host of downballot races
          • take a job working on any of the emissions reduction measures the IPCC recommends over the next few years
          • cut your own household emissions

            Talk with people about it, to help build the political will for action

            This seems hopeless. Most people are hard right-wing, think global warming is a hoax, and will instantly classify anyone who claims otherwise as a liar.

            How do you politically influence non-western-friendly regimes/countries? That’s more than 2/3 of all the polution/emissions.

              • You work to make renewable energy the cheap way to do things.
              • You impose a tariff on the embedded emissions in imported goods and services.
              • You appeal to the shared interest in a habitable planet

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.
