Climate - truthful information about climate, related activism and politics.

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.

There's just too much going on for any one person to understand it all. Never mind accounting for the geopolitical, economic, and cultural factors of every situation. Than there's the rapidly changing contexts. New technology, new science and physics, new species of bacteria/fungai. Rediscovering of ancient practices. Regional problems and solutions. I could go on and on.

I advocate for "futuristic solutions" but I acknowledge that transition will not be overnight or always linear.

So what is going on out there? That's what I'm asking c/climate@slrpnk

  • What's going on in your local region / etc and what is the political or economic context.

  • Which solutions are being implemented or developed

  • Who is organizing and leading their community towards solutions

As a Canadian I'm aware that we're expanding our LNG/Fracking, mineral mining, and oil... First Nations groups are providing some pushback against those projects, but we can't expect them to hold the line on ecological protection (There's a clear fiscal incentive for them to give in).

Canada also has and ongoing protest to stop old growth forest logging, which has gotten out of control. I honestly don't know what to think about our forest management, because I'm under the impression that logging can be done in an environmentally friendly way; but it isn't.

Canada also has a lot of old hydro-electric dams which are bad for the rivers and their immediate environment. https://www.ucs.org/resources/environmental-impacts-hydroelectric-power

I'm hopeful Canada's growing role as a global commodity supplier will allow us to set higher international environmental standards.

I've also read online that there are already climate refugees from both rising oceans and regional droughts upending agriculture in the middle east.

technical readiness level for hydrogen production is lacking. adoption is slowed down by chicken egg problem (steam methane reforming vs pyrolysis/electrolysis)

but yeah. I sign your points.
