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.

A lot of our grid is actually comprised of various smaller entities. Advanced Reconductoring could help, as building new lines takes ages due to permitting and localized red tape. We don't have a central authority to coordinate building new lines, so upgrading existing lines to better technology could allow us to get closer to bridging the gap.

However, one of the downsides is that it will still be difficult to connect new solar and wind farms in remote areas, due to the need to build virgin powerlines spanning urban-rural areas. This is one tool we can do in the present - near future in order to improve our grid. Another is advanced monitoring sensors so we can transfer more electricity without accidently overloading transmission lines. Both are relatively low-cost alternatives to building new lines.

Just Have a Think covered this as well. Seems like a great solution all around as reconductoring doesn’t require permits or issues with acquiring eminent domain. They get reduced sag, improved efficiency and greater capacity in one go.
