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.

I'm only in my thirties. I don't really think I had like..... A huge hand in all this.

Well it can't be the billionaires or the boomers, so it must be your fault.

This is what late stage capitalists actually believe

We should still try to do something, because it can become worse. So it's still an actual problem to make other people believe it's a thing...

A single cruise ship does more damage in one day than 50 people who drive a car every day of their life until they die of old age. The idea that any one average Joe has had a hand in this is a massive and intentional corporate driven fallacy to keep the public unaware of just exactly what magnitude of damage a very small percentage of people are doing to the environment.

You're good dude. It's not your fault.

You're conflating greenhouse gas emissions with particulate pollution. Particulates damage lungs and drop temperatures, but fall out of the atmosphere within a few weeks of emission into the troposphere.

CO2 accumulates, and raises temperatures.

You don't think heavy fuel oil releases CO2? Heavy fuel oil releases a ratio of 0.85 carbon specific content by weight vs gasoline's 0.90.

https://www.engineeringtoolbox.com/co2-emission-fuels-d_1085.html

I get what you're saying, that heavy fuel oil is much worse for pollution, but I don't think that the difference between the carbon emission rate between heavy fuel oil and gasoline is enough for an accusation of conflation when my initial point was that a single cruise liner burns 150 metric tons of fuel in a day.

Can you visualize 150 metric tons of fuel? Cars measure their intake by gallons.

That 0.05 difference is the discrepancy between saying that's only 49 lifetimes worth of car driving vs 50.

The stats linked above are for the sulfate emissions.

What you're doing is trying to discourage action, and that's not ok here.

[–] [email protected] 7 points 1 year ago

I mean in defense of the other person. It sounds more like the argument is trying to encourage a bigger action. Like don't just do your part, vote/participate for what actually changes things in a larger scale.

  1. The very first sentence of the article reads "calculating CO2 emissions" and doesn't mention or convert to sulfate emissions at all. What are you even talking about?

  2. What I'm doing is pointing out that change has to start with the most damaging factors in our society. I'm not discouraging action, I'm only revealing the scale of the contributors.
