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.

induction roadways

Do you mean railways?

This would be incredibly energy inefficient first of all, because a lit of energy gets lost when using induction and that rises really quickly with the distance from the source.

Second of all, that would be really expensive to build.

Third of all, this doesn't solve the real problem of individualized travel. Cars are really inefficient, becuase: 1. Their infrastructure wastes a lot of space. Most people travel alone in their cars, which means, you have all this sourounding machinery you need to transport in addition, which is huge. Cars get into traffic jams, so the city decides to widen the rode. This moves the whole city further appart, which means people need the car more often, which means there are more traffic jams. 2. They are hugely energy inefficient, because (as said before), you need to move the whole car around just to transport one person 3. They are the most dangerous mode of travel and most often endanger bike drivers or pedestrians. 4. They are loud and stink

You could solve most of these problems with proper public transport. These "futuristic" ideas, like inductive roads or Musks Hyperloop are just a way for big companies to direct funding and attention away from public transport.
