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.

Wait until the permafrost melts and releases its trapped methane. If you think the existing CO2 models are disturbing we're in for something much more rapidly catastrophic.

No. The motherfuckers that have us all in a stranglehold are, we just get gaslit into taking the blame and responsibility for it.

Consumers are collectively to blame. We need to deal with personal inconveniences en mass and Make difficult life changes like not driving whenever possible, not eating meat, not buying new products, repairing and sharing. The corporations only survive at the hand of the consumer.

I really can't tell if you're serious or not.

[–] Phil_in_here@lemmy.ca 2 points 1 hour ago (1 children)

They're serious and oblivious.

It's delusional for people to think we can just keep going on business as usual and wish for magic that the billionaires, politicians and corporations will fix the issues we've all collectively brought upon ourselves. We have to take action from the bottom up

Does "we're all fucked" sound like an underestimation to you?

70s, 80s and 90s = peak humanity.

i don't think most people are laboring under the illusion that the world will be okay, just the illusion that they and their local community will be okay

I don't know anymore.. I'm more confused about the severity of climate change as time goes on.

Climate change is not a big deal if the life a person is expecting to live is only a slightly more stressful version of a life without climate change (I think this is where we are currently). It is a big deal if it has the same degree of impact of that a mental health disorder might have - work, relationships, and overall lifestyle are significantly impacted and that person needs to make major adjustments to learn to live with it. I don't see a middle ground here, but I'm also not thinking that hard about it.

I don't know where we are going. And yes... I know the world is a big place and some people are going to feel the worst aspects, but to keep things simple (and relevant) I'm only thinking of other "middle" class Canadians living in large urban centers. If this argument takes into account every person on earth then the answer is just going to be a meaningless 'yes'.

I don't know where we are going.

Famine, war, collapse of civilisation, rise of warlords, loss of knowledge. Everywhere. Within our lifetimes.

Just look at the first of those and the rest follow. Think about how likely it is our civilisation will be able to grow crops in the quantity it has up until recently, even five years from now, given the increased frequency and severity of extreme climate events.

I had a conversation with a friend. A well educated friend, who has devoted his life to the cause

He thought he was fighting for his children or grandchildren. I told him no, we've been saying that for two generations - this is our problem. We will feel the hurt. Your water supply is not guaranteed, our food so supply could run dry one year. Our parents were told this was a future generation problem - we're that generation... This is already happening

In the US, in the EU - some places are already feeling it, but we will all feel it soon

[–] mayo@lemmy.world 1 points 30 minutes ago* (last edited 29 minutes ago)

Shouldn't we put more weight into your friends opinion?

Another person replied to me with a list of things that are a constant in our world. Except 'collapse of civ' which is exactly the kind of conclusion I'm raising doubts on as there isn't as much to support it. Again, focused on regional impacts and not places that are going to be obliterated.

Another person said 'wait till permafrost melts'. This is already baked into models, it's not expected that all permafrost is going to melt everywhere.

Idk. I'm eagerly waiting for AR7 and I'm regularly checking in on a few places. I'm aware of the narrative that IPCC leans towards conservative estimates or is overly optimistic. Internet forums don't seem to offer much to this conversation and it's mostly people echoing what they already believe. I'm not seeing any exceptions to that norm here in this thread.

The few places:

An article/search topic that swayed me a while ago:

I expect that geoengineering is going to happen on a larger scale, it would be counter to how people operate to not pursue that option.

If only CO2's warming properties had been discovered in 1856. If only good models of global warming had been created in 1896. If only those had happened, maybe society could have taken more substantial actions...

I got a vasectomy so my kids won't suffer it, and a crock pot to slow cook/tenderize the long pork.

All set.

If by 'we' you mean the billionaires and political leaders in a position to do something, then absolutely.

[–] brrt@sh.itjust.works 3 points 1 day ago

I think it’s more likely that they understand climate change much better than the average Joe. They just know it won’t affect them as much and as soon as it will the average Joe.

[–] 5714@lemmy.dbzer0.com 2 points 1 day ago (1 children)

We are voting for and consuming from those saboteurs. We could do otherwise AND incite something else.

People with active/passive voting rights and above global average purchasing power: People in stable representative democracies with mixed economies.

[–] umbrella@lemmy.ml 2 points 5 hours ago (1 children)

voting rights mean nothing if the candidates represent the rich, not us

[–] 5714@lemmy.dbzer0.com 0 points 4 hours ago (1 children)

Better a rich useful idiot, than a rich enemy.

[–] umbrella@lemmy.ml 1 points 4 hours ago* (last edited 4 hours ago) (1 children)

lol we are the only useful idiots here, they wouldnt be rich otherwise

[–] 5714@lemmy.dbzer0.com 1 points 4 hours ago (1 children)

What keeps you from getting voted then?

[–] umbrella@lemmy.ml 1 points 3 hours ago* (last edited 3 hours ago)

copious amounts of money for a political campaign, or terrible ethics so i could accept to pass shitty laws later in exchange for it

Probably. We’re clearly avoidant on this topic.
