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.

While scientists have spent decades covering how extreme heat and cold lead to death, new research using data from California emergency departments shows that the heat may be making us sicker too.

My work is a small factory without AC. Even the owner has complained about the heat. I sweat easily and a lot so my days are spent painting the floor with sweat. Every day feels like I am a wrestler trying to lose weight and make the cut. I can at least count my blessings and take confidence in that my body temperature is too high for any viruses to make camp. Maybe I'll be patient zero for water bear infection.

The boss told me that if I work hard and sweat out another 10lbs he can buy another corvette. /s

I work in similar condition, but unfortunately the owner has a nice air conditioned office on the off chance he's even at the factory so he doesn't give a shit. After 7 years of this crap I finally started recording the temperatures and humidity this summer so I can calculate the heat index and then I can write up an email to send to the health and safety team that I'm part of at the end of the summer to really give some data as to what we actually deal with. Maybe someone at your factory can do the same thing to try to make an argument? It's one thing to check a thermostat that's reading a dry temp of 88-92, but if you were able to show in real terms that's actually 100°+ it might help.

Not even halfway through the summer and we've already had over 2 weeks of 100°F+ temperatures... Hit 106° 3 times and 109°F was the worst so far. Hell I'd be thrilled if they installed some system that only activated at ~90°F heat index, I don't need 67° perfection, just anything to not be roasting all the damn time.
