Oh naturally, I think you've hit the nail on the head there. Tell me, how does one conduct a scientific study on feedback loops which haven't happened yet? Then tell me how many peers would be willing to risk their funding to verify such a pessimistic prediction?

I know they're about emissions reduction, I didn't say they weren't and I don't understand your point. All I'm saying is that it's all well and good stating what we need but the feasibly of implementation is laughable.

I suggest you look into the resources required to extract the smallest amounts of carbon from the atmosphere. To quote Dr Hugh Hunt of Cambridge...

We don’t do anything on this planet at that scale. We don’t manufacture food on that scale, we don’t mine iron ore on that scale, we don’t even produce oil, coal, or gas on that scale.

Completely agree with you re the WWII mobilisation. That would require every government in the world to work together in actively worsening the lives of their citizens. Not exactly a vote winner is it?

You model them. A great example was the ice-albedo feedback, where you could measure the albedo of ice, and the albedo of open water and bare ground, and reach clear conclusions about how losing ice would create differential warming in the arctic.

The modeling work won't ever be perfect, but it's good enough to have incredible predictive power.

And yet still the ice is melting faster than expected and faster than that model predicted, because, as you explain, the models are inaccurate (overly conservative in nature as all scientific studies on complex systems tend to be).

Ice sheet dynamics have been an area where scientists haven't converged on agreed-upon models. So yes, not everything gets there, but an awful lot does. As I said above, enough to be useful.

[-] Redacted@lemmy.world 2 points 1 year ago

You seem to keep supporting my point.

The models are conservative, the peer review process is long and we're rapidly running out of time.

[-] silence7@slrpnk.net 1 points 1 year ago

It's more complicated than that. The temperature modeling is roughly right. Secondary effects aren't as well modeled, and surprise is a lot more likely there.

Sorry, couldn't resist.

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.
