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.

This article focuses specifically on the warming and the depletion of oxygen in our rivers. I watched the video, but I didn't read the text. I think it is just a transcript from the video.

The best way to save any part of our environment is to get more people to engage with it. Whether that is fishing on a river, hiking through the woods, or any other outdoor activity. These activities have routinely been proven clinically to improve a person's health and well-being. If we can get more people participating in this positive feedback loop, we will have more interest and political will to protect our environment.

It's only mentioned that warming in general is causing the lack of oxygen in the rivers. Well, what is causing the warming? They mentioned sedimentation, but they don't connect that more large rain events lead to more sedimentation, more sediment in the rivers absorbs more sunlight and holds heat. They mentioned removing old dams to make the water run faster which will keep it cooler. That's a great thing to do, but we really need to focus on increasing the buffer zones between rivers and development and showing up the banks along our rivers.
