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.

The same reason everything else gets ignored.

Our culture pushes us to ignore it because its only really a problem for poor people, and fixing it would mean less money for rich people.

Can't get in the way of those revenue streams, that's socialism!

The last sentence ends with:

we are the problem.

The answer to the title question is chasing after short-term profits at the expense of all else - as we all understood perfectly before it was asked - and therefore the true underlying answer is bc clickbait title gets more clicks if it seems to ask a simple question than if it does not.

The article itself seemed mostly fine, if extremely wordy and rambling, but perhaps I was so put out by that "trick" with the title that I did not give it a fair chance - it just bugs me so much when people chase short-term profits to the exclusion of all other considerations, that I find it difficult to look past that effect:-|.

You mean that it's NOT a good idea to move to the middle of the desert, pump in water from afar, and burn up ungodly amounts of fossil fuels in an attempt to stay cool?

I see your logic, and I raise you... "golf". (I win! And then we all lose...)

I get what you’re saying but heaters are way worse than air conditioners in terms of emissions. People in New England getting diesel fuel — branded as “heating oil” — deliveries in winter isn’t questioned in the same way as Phoenix residents running their (electric) A/C is.

The American Southwest has been continuously inhabited for millennia. I don’t live there but I know I get lectured about where I live — New Orleans — by smug fools whose framework for understanding the world seems to come entirely from the Grasshopper and the Ant fable where preparing for winter makes you morally superior to everyone else.

There's definitely some truth to the asymetric way we talk about heating dominated vs cooling dominated climates. I don't hear people criticize folks for living in Alaska or the upper Midwest or NE despite their massive heating costs, and this type of living isn't inherently any more noble than AC use (although synthetic refrigerants are all awful, but we use them for heat pumps too). Lack of water is a bigger issue arguably, cold is seen as more survivable than extreme heat, but carbon is carbon. The American SW used to have more water though, and their civilizations lived quite differently than modern Phoenicians.

Example numbers - I live in Colorado, have a high end cold climate heat pump, and use 10x the energy seasonally to heat my home vs cool my home. I also make excess solar power even when cooling in the summer, but winter is another story. I used 10 kWh yesterday when it was 100F (an amount an EV owner might casually use every single day), almost all covered entirely by my solar panels (except dusk until about 10pm when it shut off), while the coldest day last winter was -15F and I used almost 80 kWh that day, almost zero of it from solar because snow on the roof. We're not going to get everyone to move at the macro level, so micro level movements, resiliency, and adapting to the environment rather than fighting it make the most sense.

The grasshopper and ant parable is about preparation and not the virtue of winter. It's equally applicable to heat waves, storm surges, flooding, water, etc.

temperatures reached a record 128 degrees Fahrenheit.

Which is about as hot as a water heater.

growing up, the most common 'counterargument' (read: dismission) to 'global warming' i heard was 'great, i love summer!'

i had to become a singer before i had the lung capacity to sigh hard enough.

Coming from the UK where we often have cold wet weather, a nice warm summer sounds wonderful.

“You want warm weather? How about we destroy the planet”

oh wait no please, not like that

[–] cerement 1 points 4 months ago

how else are the British supposed to find all their archaeological sites?

HMMMMMMMM, I wonder why? 🤔
