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.

Also if you want to drink something with a taste, always consider adding tap water to it. Most lemonades mix very well with tap water. Furthermore, not everything you drink requires carbonated water to taste good. Sirups that mix with water in a big ratio like 1 portion of sirup and 10 portions of water are nice too.

Carrying home 10kg of drinks every week seems like such a waste, I never understand people who do that.

Of course if tap water is contaminated because of a flood or some other accident it makes sense not to drink it. That said I think in many places tap water is usually cleaner than bottled water (some more so than others). I understand that I can't generalize, but I think everyone who hasn't should at least read up on the water quality of their region, ideally on official or trustworthy sources.

(edit: Note that I wrote the following paragraph without knowing tap water temperatures. Apparently it only holds true if your cold tap water is below 15°C.)

And since I'm already ranting: You don't need ice in your drinks! It doesn't make the drink tastier or more refreshing. It's just a waste of time and especially energy, and also a contamination risk. You also don't need tap water into the fridge. Just let your cold tap water run for a few second and it'll rinse out the stagnant water that warmed up to room temperature, replacing it with fresher, colder water. I guess in some place this might be more viable than in others. Always depends on the local availability of water and energy.

Yes, putting ice in water does make me enjoy it more, and no, letting the tap run doesn't do nearly as much to cool it down as ice cubes do.

How is it more enjoyable to you? I don't get it. Do you enjoy the temperature or is it an actual taste thing? Letting the tap run makes water so cold for me that I usually wait for a couple minutes before drinking more than a few sips.

Apparently your tap water is dramatically colder than any house or apartment I've lived in.

Alright this topic bothered me so I figured the onus was on me and looked it up. Apparently cold tap water temperatures in some cities around the world are usually around 15°C and can go as high as 25°C in summer. That's definitely not my experience, I'm pretty sure it's constantly below 15°C here. So then you're not a crazy maniac and the regional differences really are way bigger than I expected. Who would've thought!

I carbonate tap water all the time, it works great.

Most people i know that prefer bottled water prefer it because of the chlorine taste in their city tap water. Most bottled water goes through several processess including softening or reverse osmosis which can impact the taste quite a bit. They often remineralize the bottled water and add flouride as well. They do make undersink reverse osmosis systems for people who have taste or odor concerns from their tap water, essentially getting a similar quality to bottled out of a tap.
