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 road is long, and much of the map remains blank. The biggest problem is drilling miles through hot rock, safely. If scientists can do that, however, next-generation geothermal power could supply clean energy for eons."

The image is a test brick being spun around under the output of a MASER which is a type of directed energy weapo...tool. This is normally highly controlled to run tokamaks but they are trying to make it less expensive and adapt it to shot dirt and rocks to evaporate them and easily penetrate at 1meter per hour for around 100 days...~3km deep.

Didn't see that in the article, sounds interesting ... where can I read more?

You can check them out here in their websites: https://www.quaise.energy/

There's a pictogram schematic of their maser system. The little tube part above the molten pit is called the waveguide. Waveguides allow the transport of energy from the source to elsewhere. The wavelength has to be tuned such that the receiving end..rock.. Actually absorbs the power. Otherwise the amplifier would receive deflections and either overheat or blow up.
