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.

  • Ban cars on sundays again.
  • Remove all harmful subventions on meat production
  • Ban the installation of fossil fuel based heating
  • Everyone can buy a bike today, it's on the state!

I'd add:

-properly tax jet fuel.

-Huge tax on private jet, which should go toward help toward green transition: fund R&D, electrification for Heavy industry, renewable energy production, green mobility (train,...) ...

  • Ban the installation of fossil fuel based heating

We did that.

I'm surprised. I don't think it is done nation-wide. In which canton is it done?

Nation wide no new oil heating allowed anymore since 2023. Old ones can still be used though.

Edit: let's rephrase: new heating must be renewable.

I remember this news end of last year discussing that we still installed a lot of non-renewable heating:

https://www.rts.ch/info/suisse/2024/article/les-suisses-se-detournent-des-pompes-a-chaleur-pour-revenir-au-mazout-et-au-gaz-28709157.html

Pour accélérer ce rythme, la solution pourrait être politique. Le peuple suisse a accepté l'an dernier de soutenir financièrement la rénovation des bâtiments, grâce à l'isolation et à l'installation de pompes à chaleur. La Confédération va investir deux milliards de francs sur dix ans dès l'année prochaine.

Il s'agit là de mesures incitatives, mais certains cantons misent, eux, sur des interdictions. A Genève par exemple, à quelques rares exceptions, les propriétaires ne peuvent pas installer des chauffages fonctionnant aux énergies fossiles.

En Valais, par contre, les chaudières à combustible fossile sont toujours autorisées lors des rénovations. Toutefois, à partir du 1er janvier, le Canton posera certaines conditions, notamment sur l'isolation des bâtiments.

Si les réalités régionales varient, le défi est national. Plus de 50% des habitations suisses sont encore chauffées au mazout ou au gaz. Et devront donc, à terme, être rénovées.
