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.

Trudeau deserves all the grilling. He’s made promises over promises about curbing emissions all the while pushing for petrol in practice. He’s losing popularity fast domestically too -- but the conservatives are picking up steam to replace him at the next election. Those ones don’t even pretend to care.

Yeah JT is in a tough spot because the liberals are essentially corporate centrists, they will say lots of lefty fluffy stuff to get elected but then their corporate masters (oil companies primarily) wont let them do any of it. And the only viable alternative for Canadians is the conservatives who will definitely trash the environment completely if they get a majority.

Oil is one of the greatest natural resources we have and we will always need oil, we just need to STOP BURNING IT FFS

We won't always need it. It'll run out eventually so it has to be replaced at some point. Even if you ignore the climate change part.

If it was restricted to use in necessary cases such as sterile packaging of medical tools, it would last so long as to be effectively forever. Thousands, hundreds of thousands of years.

[–] charliespider@lemmy.world 4 points 1 year ago

Yes medical equipment is the primary use that comes to mind for me.

So we should... drink it? I mean what else can you do with it?

[–] charliespider@lemmy.world 7 points 1 year ago

I wouldn't be surprised if half of everything you own includes some form of plastic. Phones, cars, appliances, even clothing is made from petroleum.There's a LOT of things that could be replaced with non-petroleum products (like textiles) but there's also some fields like medical equipment that we should be saving our reserves for.

Aspirin is made from oil, benzine is derived from petroleum.

As is paracetamol and ibuprofen

The world needs to collectively come to the conclusion that politicians are not going to do a single meaningful thing to help curb the climate crisis. It’s not in their interests to ditch fossil fuels or make any strides that reduce power or income.

I hope they used clean propane to run that grill

[–] BreadOven@lemmy.world 2 points 1 year ago

Not that bastard has, butane. I tell you whut.

EVERY LEADER IN THE WORLD needs grilling. They need the balls to say "NO" to money in politics and be held accountable if they don't.

[–] MrMakabar@slrpnk.net 3 points 1 year ago

What was it again. USA, Canada, Norway and the UK making up over half the worlds new emissions in gas and oil drilling. I mean none of them really need the money or even the energy.
