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.

To sum it up. The inital thought was that the bill would be a public investment of $385 billion in renewables, but it seems it will be more in the line of $1.2 trillion, so about three times more money. Certainly a big change and extremly good news.

I don’t like any politicians but I am willing to put this guy or his party back in in 2024. IDC what happens. Another liar zombie conservative is a waste of time and life.

And to be honest, we’re running out of time.

No doubt. I mean I look back and carter, reagan, bush, clinton, bush bugaloo, obama, trump, and biden and only half of those administrations ever did anything useful for me. I remember when the bush tax cuts allowed me to afford a drink at the bar. woohoo.

[–] [email protected] 14 points 1 year ago

This combined with the fact that utilities like renewables due to their cheaper deployment and opex and you've got something going. Now all you have to do is accelerate and cap the depreciation of old equipment. Thanks Joe.

This is good news.

Love the idea, but: A lot of rich people will get much more rich. There will be a lot of money wasted on things, that will not work and the grifters will know that it was not gonna work. There are numerous examples from the „green coal“ projects that siphoned off a lot of money with unrealistic ideas without repercussions. The more desperate the world get for fast solutions regarding climate change, the more money will be thrown around unvetted.

Mind you, a lot of is getting spent on things we know work, such as wind, solar, storage, and electrification.

don't forget insulation. Its the cheapest, easiest, quickest return on investment green thing there is.

The alternative is doing nothing, and we know how that's gonna turn out

Goldman Sachs expects higher-than-expected private investment in all green energy categories affected by the IRA, but sees the biggest gains in two areas: electric vehicle production and advanced manufacturing.

Neither of these are green energy.

Electric vehicle production is green energy in the same way that renewable powerplant construction is green energy. Both enable the US to reduce its reliance on fossil fuels and move towards a more sustainable energy grid.

No true Scotsman doesn't help us.

They're greener than the existing alternatives.

[–] [email protected] 3 points 1 year ago (1 children)

Im not saying theyre green energy that dont deserve the title, im saying theyre literally not energy production. EVs are an energy use.

[–] [email protected] 5 points 1 year ago (1 children)

You don’t think green energy use qualifies as a green energy “category” that one could invest in?

[–] [email protected] 3 points 1 year ago (3 children)

it's not green energy use. it's just energy use. EV's predominantly run on fossil fuel energy in the US.

[–] Kage520 4 points 1 year ago

True. EVs plus those crappy fossil fuels power plants though are still more efficient at using energy, and thus better environmentally, than ice cars. We really need more nuclear and renewables here though. It's pretty bad and it doesn't have to be.

[–] [email protected] 2 points 1 year ago (1 children)

It’s the capability for green energy use, in a very energy-intense application. That possibility is not there with combustion engines.

We cannot have a green energy economy unless all the usage endpoints consume clean energy rather than hydrocarbons.

[–] [email protected] 2 points 1 year ago (1 children)

most things that use energy are capable of using green energy, you wouldnt call an investment in a coffee machine company a green energy investment. We need the green energy first.

[–] [email protected] 3 points 1 year ago

Anything that already runs on electricity isn’t really part of the discussion then, because there’s no need to change anything at the point of use.

A better analogy to the car thing might be investing in (or subsidizing) heat pump production over natural gas furnaces.

[–] [email protected] 1 points 1 year ago

Everyone having a hard ime on this, EV are not green energy production, widhout green poweplants very little changes with more EVs.

[–] [email protected] 2 points 1 year ago

They are ways to use green energy, just not ways to create it.

[–] [email protected] 3 points 1 year ago

Finally some good news from the US now that the orange idiot is gone
