It's just too expensive to save the planet. I'm glad that our governments were making the tough Choices, to continue burning coal and other fossil fuels because the economy just couldn't handle the burden of not growing by another 5% every year.
- That's a fair complaint for developed countries, but I feel like it's less fair for developing countries where each point of GDP growth has a tangible effect on poverty rates, education, health, economic mobility, and overall wellbeing. Hell, an increase in economic resources will probably even offset the decrease in crop yield from climate change. For countries that are still developing, these things improve the lives of citizens more than the impact of climate change would hurt them.
  Living in a developed country, we have a disproportionate responsibility for both reducing our own emissions and developing the technology and infrastructure to reduce emissions for everyone else. We should have led the charge towards ever cheaper solar and ever cheaper wind. We should have given the world clean and cheap technologies they can use to fuel their industrialization to reduce their reliance on fossil fuels. We haven't, but looking towards the future there's still a lot we can do.
  Remember that you can influence global emissions far more than by bringing your personal emissions down to zero.
  
  Yes, exactly, the developed world should aid the developing world as much as possible in providing them clean technologies.
  We are rich enough. We can afford that. And we all benefit in the end (because, after all, a lot of our supplies originate from developing countries).
  
  None of the countries historically responsible for the most CO2 emissions is growing at anywhere near 5%. If anything, we're burning our only home for 1% year on year.
  
  Also worth remembering that governments are subsidizing the fossil fuel industry. What should happen is that this industry should be nationalized and the profits should be used to build out clean energy infrastructure.
- I am so glad the shareholders got their money!
  Just imagine some rich people didn't get more rich, just stayed as rich as they were, so we could "save the planet". Disgusting!
- Had the misfortune of listening to State Department and White House policy ghouls talk to a class recently. They don't believe moving to less fossil fuels quickly is viable because we'd become "dangerously dependent on Chinese minerals for batteries and solar cells" ignoring the fact that the entire globe is "dangerously dependent" on a liveable climate

- Ok this is an idiot question but how does the global average temperature change so much over the course of a year. Is the northern hemisphere warmer overall during its summer compared to the southern hemisphere in its summer?
  
  I don't know the answer and was wondering the same thing, but the southern hemisphere has a lot more ocean, which I'm guessing is the difference.
  
  I suppose there is more landmass on the northern hemisphere. Landmass is more prone to temperature changes because water dampen the change while land quickly absorb or radiate the heat.
  
  There is a theory based around how ocean tankers' exhaust historically included sulfates, which can actually seed cloud formation.
  Recent emissions regulations reduced this effect, so fewer clouds are being seeded over the ocean, and the oceans are absorbing more sunlight and heating more.
  So we were basically painting large swaths of reflective clouds over the oceans, masking the heating. And now we're seeing unencumbered heating effects.
  
  I would presume the Earth would be hottest during periapsis (closest point to the Sun in its orbit) and coolest during apoapsis (furthest point to the Sun in its orbit).
  
  I think it's because the Northern hemisphere is a lot colder during winter compared to the southern hemispere in its winter, or at least one reason.
  
  It's like when you start pushing something and the friction goes down, making it easier to push. Except for most of the last century we've been pushing increasingly hard against the climate.

Scorching hot take, heard this week offline
"Climate change is actually a good thing because necessity is the mother of invention. If you have any faith in humans at all, climate change is just what we need to make humans an interplanetary species!"
- That take just increased global temps to the 2 degree mark.
- It's also a great way for mother Earth to teach us a hard lesson. How else are we to learn that we can't have whole species on one "basket". No, a good planet to start off on could mars. Now all we need is to invent, invest and grow the smart ones. It's just so hard to do so with so many yachts for sale.
  
  Did you forget /s after all this?
  
  get in the bazinga rocket — we're solving climate change by fucking off to a planet we've never even set foot on!
  
  we can't have whole species on one "basket".
  why not?
  
  Earth is the most hospitable planet to human life in the entire universe, and we seemingly can't even put in the meager effort to keep it habitable. What makes you think we'll be any better at making Mars habitable? Not just keeping it habitable as we've failed to do on Earth, but making it habitable in the first place.

can we please fucking kill oil and gas executives now? i know it's not gonna save us but we deserve something

We ded
- We ded
  Most likely outcome (high confidence)
  still letting this here: https://www.science.org/doi/10.1126/science.aba7357
- Oh yeah. We are definitely fucked

That's capitalism efficiency for you right there, climate apocalypse is ahead of schedule.

Earth

Hell yeah were so fucked
- Fuck yeaaahhhhhh!!

Okay but that image goes hard. Literally looks like they're holding fire in their hand.
- Even without optical illusions, drip torches are pretty fun to work with.

This is the best summary I could come up with:
In 2016, influenced by a strong El Niño event - a natural climate shift that tends to increase global temperatures - the world saw around 75 days that went above that mark.
One theory - which is still uncertain - is that a fall in air pollution from shipping across the North Atlantic has reduced the number of small particles and increased warming.
Up until now, these "aerosols" had been partly offsetting the effect of greenhouse gas emissions by reflecting some of the sun's energy and keeping the Earth's surface cooler than it would have been otherwise.
While the northern hemisphere will naturally cool in autumn and winter, there is a view that the large temperature differences from the pre-industrial period may persist, especially as El Niño reaches a peak at the end of this year or early next.
Researchers believe that these ongoing high temperature anomalies should be a wake-up call for political leaders, who will gather in Dubai in November for the COP28 climate summit.
In March, the UN urged countries to accelerate climate action, stressing effective options to reduce emissions were available now, from renewables to electric vehicles.

- This is a terrible summary.
