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.

And that's why I'll never leave the Great Lakes region.

Where are they implying it went? Did it evaporate out into space? Was it absorbed into the earth's crust? Or is it just becoming unpotable - and if that, how does the change in earth's wobble that they use to make this claim imply that water has lost it's freshness?

There are over 8 billion people on earth. People drink, wash, and shit in multiple litres of water daily. Crops require water. Livestock requires water. We slaughter several Trillion (with a T) livestock globally each year, there is A LOT of livestock. Industry requires water. Industry is trusted not to hoard, pollute or waste water. Water processing and sewage reclamation requires well funded public infrastructure. The hotter our atmosphere is, the more water vapour it will hold.

Just some ideas to get you started.

I understand the basic overuse and mismanagement :) All of these things are true and quantifiable to a point - But I did mean to ask how was this measurement indicative of a specific amount of despoiled water, if all that satellite measures is relative changes in gravitational motion. A re-read of the article and this segment seems to have answered the question - "dumping more rain in faster and more powerful storms that are more likely to run off than to seep into drier and more compact surfaces." which seems to mean it was indeed being absorbed instead of staying in sloshy bits on the surface or becoming atmospheric, therefore causing detectable gravitational wobble.

Thanks though, for the clarification.

Nations must start to manage water as a global common good,

it's been nice knowing you all

Nestle: We've lobbied governments around the world to ~~let us own all the fresh water~~ protect the fresh water from nefarious actors.

I've said it before and I'll say it again, my retirement plan is dying in the potable water riots

...I vote we decide on a climate landmark to establish the initiation of the global end of the world party. Anything that's currently illegal due to longer term consequences goes into 'fuck it!' territory. Drugs of all kinds completely legalized; conditions that contraindicate using those drugs like pregnancy are ignored. Social standards around things like sex are dissolved (other than consent - that stays). Just nonstop hedonism, feasting, drinking, fucking, etc while supplies last.

Then when supplies run out, we all hit the big red button at the same time. Nukes. All of them. Detonated in as close a synchronization as we can get them, and our failure of species goes out in as painless as possible of an instant flash.

.....I mean, it's that or slow-burn to death anyway, we got nothing to lose.

Just try organizing a militia and you will find how oppressed we already are

The only thing that works now is indiscriminate attacks on the wealthy, it's the only thing they won't see coming

Climate change terrifies me to be honest. We have seen how under prepared we were as species for covid, this will be so much worse. While we could be doing something about it we still have people who dont believe it or are doubling down on fossil fuels and taking private jets.

It more surprises and saddens me that we are less than 2 generations divorced from when we as a species were able to band together and ban CFCs to address the hole in the Ozone Layer, as well as sulphurous compounds to eliminate Acid Rain - yet we’ve flown right past ‘fuck around’ without seemingly batting an eye, and are barrelling towards ‘find out’ territory when it comes to Climate Change..
