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.

It absolutely IS the safest pipeline in the world.

Which is to say, oil pipelines are all unsafe.

The only thing more dangerous is trains and trucks.

They don't say how big the spill was

~~3500 gal. (13,250 liters)~~

Edit: either I fucked up or the AP updated. 3500 barrels of oil. 147000 gallons (556,455L)

To put this number in context: I live about a mile from a gas station where the driver of a gasoline truck with a capacity of 8000 gallons decided to dump 4700 of those gallons into a ditch behind the station because he felt like going home and didn't want to go on to the other stations he was scheduled to deliver it to. For bonus points, this ditch was between the gas station and an elementary school.

So not to excuse this, but 3500 gallons is not quite Exxon Valdez or Deepwater Horizon territory.

Whoops: either I fucked up or the AP updated. 3500 barrels of oil. 147,000 gallons (556,455L)

Just under a quarter of an Olympic pool.

OK that's a bit more than my local idiot (who went to jail for it, BTW - unlike any oil company executives, ever).

Thanks to Trump the Canadians are pissed at the US. So hopefully they stop selling oil to the US, which means shutting down the Keystone pipeline.

[–] [email protected] 1 points 1 week ago (2 children)

The trouble is they have no one else to sell it to. The US is their only market for it since they have no other way to get it to market.

The trans mountain pipeline was completed last year, so we can now ship oil to other countries.

[–] [email protected] 1 points 1 week ago (1 children)

Interesting... I hadn't heard that. Can it and refineries on the otherend match the volume needed to cut the US off without pain on your side? Honestly hope so. We need to suffer on this side before the idiots that vote for Trump will acknowledge their mistake.

[–] [email protected] 1 points 1 week ago

refining is still an issue that needs solving, as we do send oil to the US to be refined and buy the product back. I know for a long time it was considered un-economical to refine our own oil due to the volume:cost issues, but maybe that might change now?

[–] [email protected] 4 points 1 week ago

I'm sure the US will respond sane to not being able to get oil.

Hope you are right, but depends on the power balance after the election, and whether federal or provincial law decides such things.
Isn't Alberta is more aligned to MAGA politically? Maybe tries to stir up a big provocation, then eventually 'annex' it.
