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 was debating whether I should correct you that it was, in fact, Bobby who said this - or whether that would be pointless and rude.

While debating, I looked it up so I could source my potential claim and it turns out you were entirely correct. I apologize for doubting you!

I... guess I appreciate that you bothered to look into it and just freely admitted what you were going to say was wrong?

Lol, but no really, that kind of intellectual honesty, as well as restraint in general, are rare and commendable.

But uh, no need to apologize for an unrealized thought crime lol.

Honestly, I think it's good policy to announce when one is convinced that one's beliefs are wrong. Whether doing so preemptively is universally a good idea is debatable, but I thought it might be helpful for some who thought as I did and maybe it would even garner a laugh from you. Not that I know you in any particular manner.

All that cheerfulness and attempt at morality aside, it can be hard to take the same stance once one has defended one's position, so maybe this is good practice for when I've actually stated my beliefs and need to swallow my pride.

Hope you're having a great weekend!

Likewise, in all respects and regards!

Hope your weekend goes well too.

The world objectively would be a better place if more people spent more time second guessing themselves and their preconcieved knowledge sets and beliefs, in a way that at least resembled critical thinking.

Or, in less words... intellectual humility, as opposed to incurious and stubborn overconfidence.

I'm pretty sure I'm in one.

Only if you join me in it and also let me give you a heartfelt compliment.

Oh right, we would have to make sure that room has AC, if its in Phoenix.

[–] toynbee@lemmy.world 2 points 2 weeks ago (1 children)

That person has not yet allowed it, but I'm interested in what heartfelt compliment you have to offer them.

I know less about them than I do you (I've seen a few of your other posts on lemmy) so I'm genuinely curious. Complimenting strangers is a big part of my life and I'd like to learn from you.

[–] sp3ctr4l@lemmy.dbzer0.com 2 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

Hah, I mean, I don't know them at all lol, my approach would just be to have a bit of chat about how their life has been going recently, and I'd bet I could find some admirable trait or accomplishment.

Or maybe they just dress particularly well, maybe they have a pleasant voice... possibilities are endless, so long as you keep and open mind and more or less just politely say what you really feel.

... Its funny, I am quite a cynic at a broad societal level, but actually person to person? Still tend toward naive optimist.

[–] toynbee@lemmy.world 2 points 2 weeks ago

That seems excessively reasonable and I can very much relate to the last sentence there.
