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.

Is your ding dong in its path? Being tropical and all…

different tropics.

Sounds like someone could use a little treat.

Hurricane Betsy — the second storm of the year — hit New Orleans on September 9, 1965. Katrina — the 11th storm — hit New Orleans August 29th, 2005. And now we apparently have Category 5 storms forming in late June/early July.

Every hurricane season (and hurricane) is different, obviously, and that’s one city’s experience but it makes me wonder if there will even be a distinct “hurricane season” in a few decades.

Not just early July. A full 16 days earlier than the previous record from 2005. The record before that was Allen(so the first hurricane of the season) all the way back in August 5 of 1980.

They also used to be rare, and are getting less so. Since 1924, only 39 are known. Since 1960, there have been 30. 8 of those(so ~20%) are since 2016.

Iirc they're talking about adding more category levels too because 5 just doesn't cut it anymore.

Hey, I like your optimism, assuming we'll still be here in a few decades.

[–] [email protected] 9 points 5 months ago

Ironically, New Orleans might be OK because we have elaborate flood control systems and have always dealt with flooding. Vulnerable places like the Netherlands and New Orleans are what we all assume will end up flooded. (And we will.)

But we’re built for it. A river delta floods sometimes anyway. I’m honestly more worried about places where snowmelt creates small streams now but in the future, will just create terrible floods every Spring and then draught immediately after.

To me, the scary part isn’t having water in the streets. It’s climate change. We had an issue recently where there wasn’t enough fresh water draining into the Mississippi to push the salt water back. It ultimately never reached NOLA but it reached plenty of people downriver. And because of a drought in the Midwest.

Wait, isn’t this what everyone wanted?? Why the fuck have we been poisoning the atmosphere for the last century if not to enjoy more category 5 hurricanes? I’m so confused.

[–] [email protected] -5 points 5 months ago

I know right? Aren't we glad we went for the sure fire poison over the n-word option.

Yes. Ocean current changes are coming for us all.

A current not going to Europe will get their attention

[–] [email protected] 15 points 5 months ago (1 children)

Maybe focus on the Gulf Stream collapse instead

[–] [email protected] 15 points 5 months ago

It's related. Warming ocean temperatures are amplifying the hurricanes and destabilizing currents like the Gulf Stream - both symptoms of the same problem.

What does it mean about the broader* global warming issue?

[–] [email protected] 6 points 5 months ago* (last edited 5 months ago)

Good luck with your impending ice age.

[–] [email protected] 4 points 5 months ago* (last edited 5 months ago)

Considering that it's the fact that it even exists right now is the concerning part, yes.
The earth is a closed system, just because there's a very early hurricane half a world away doesn't mean the climate isn't being effected everywhere.
For you this could mean an increased amount of warm water moving in through the Gulf stream to the North Atlantic. This will bring warmer waters to the coastal regions of Europe increasing the severity of storms there, until that warmer water causes the Gulf stream to completely collapse plunging Europe into an early ice age.
The weather where this hurricane is does directly affect you where you live.

[–] [email protected] 1 points 5 months ago

Nope. Don't need to worry about copious amounts of water raining down, just the water wars.

Reminder not to donate to the American Red Cross for hurricane relief.

Agreed, kind of a bold assertion to throw out without proof against a highly rated international charity

Charity Navigator 4-star 99%

Guidestar Platinum

Charity Watch A-

Looks like there were some issues with transparency 5-10 years ago (Google "Pro Publica Red Cross"), but I'm not finding any recent follow-ups and they're scoring high marks for transparency now. They pretty consistently spend ~90% of every dollar donated on programs and are generally well-respected.

Are they a perfect charity? Probably not. But are they doing good? Absolutely.

If you want to donate money elsewhere, by all means go for it. Doctors Without Borders, and World Central Kitchen are great international charities, and local food banks in impacted communities can make your dollar go further than just about anyone else.

But also remember money isn't the only donation the Red Cross accepts - as with any major disaster, blood will be in short supply, and there is unequivocally no better network for blood donations than the Red Cross.

They use a little trick called "lying" to keep their metrics.

Their CEO, Gail McGovern, a failed CEO from AT&T, has more than tripled her own salary while cutting employee benefits and is currently overseeing the absolute worst blood shortage in history.

People just don't trust them anymore.

For some reason.
