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."

SLB had acquired Celsius Energy, a company that deploy low depth geothermal solution. They are also partner with Genvia to developpe hydrogen. And have also plans for offshore wind turbines. Oil company all have plan to transition to new energy. Then know oil is not a long terme business. The problem is doing the transition while making money. If you dont make money, you die. And if you die, you cannot do transition. Unfortunately, oil still generate shitload of money...

I'd really like to see governments enact bans on drilling new oil wells. Then suddenly all the tooling for drilling wells is freed up for geothermal wells.

While oil drilling is profitable, there is always the risk that these new companies get bought out by oil companies and told to drill for oil instead.

France has ban drilling new Wells on its territory. For now, despite oil lobbying, ban is still applied :) The problem with geothermy is more a social and legal problem. No one care about drilling in the middle of north sea. But geothermic should be drill close to population. And suddenly, everyone becomes afraid of earthquake, and you need dozens of authorizations.

France is also 80-90% nuclear from memory, so less demand for other renewables?

But valid point, its never that simple :(

More something like 50% nuclear, 40% renewable, but we also sell lot of nuclear electricity to Germany. Hydraulic is very well used. We have hydrolic power plant everywhere it's possible. Not many people know this. "Hell ya, why don't we build more hydrolic plant ?!" Well, because we already did 😅

It is a good sign that in some countries where leasing is still open, oil companies are buying a lot fewer permits
