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.

our dependency on fossil fuels hasn't changed

What is this crap? EVs are all over the place and so is renewable energy. Emmissions are falling. We haven't opened a new coal plant in a generation.

And ok, we keep driving emissions down, what about biodiversity loss across the planet? How many plants and animals are currently on the brink of extinction?

Ok? It's bad and we're working to fix it. That's very different than "we're all doomed and should stop doing anything".

Where is the international agreement to help modernize these countries with renewable energies? Who's going to pay for it?

Ok, and how environmentally friendly is it to dig up the minerals to make the batteries, ship them to the plants in massive container ships, process them through polluting means, put them into cars that were also built from resources ripped from the earth using machines billowing CO2, and then shipped across the globe in container ships that pollute more than all cars combined on Earth?

And ok, we haven't opened a coal plant in a generation, maybe in the US. China is still building them, as are a good chunk of the world. In fact, the IEA estimates to China's use of coal will be up about 6% total from 2023, while India's is an increase of 10% of coal use. They estimate global coal use will be down next year, 2025, the first time since 2016, and it's estimated to drop 0.3%.

Ok? It's bad and we're working to fix it. That's very different than "we're all doomed and should stop doing anything".

Do you understand how biodiversity works? You can't just run a population down to a handful of that species, and then they'll make a comeback as if nothing ever happened. There is not enough genetic diversity for a healthy and sustainable population to grow and repair itself from that. 69% of all life on earth has been wiped out, bud, we're not fixing that.

Lmfao, "a legally binding international agreement," yeah, ok. That's why a single President unilaterally removed us from the agreement, right? Because it's legally binding? And that's why all of these countries are taking it seriously and making huge efforts to reduce global emissions, right? They've only had since adopting them in 2015/2016 to start making progress, almost a decade, and... Omg... Omg you're right!!! We're doing it!!!

Just kidding, from September 2024:

None of the larger, industrialized countries or the European Union as a whole are currently on track to meet the 2° Celsius goal. African nations Nigeria, Ethiopia, Morocco and Kenya as well as Costa Rica and Nepal are named by the Climate Action Tracker to be on track to meet the 1.5° Celsius goal using a fair share approach, while Norway is predicted to meet the 2° Celsius goal. The website analyzed the climate policies of 35 countries and the EU.

Wow, so the countries that are supposed to be leading the charge aren't even on track to stop 2°C temperature rise, nevermind the 1.5°C we're supposed to be aiming for.

But we've got more electric cars, and we're still consuming and ordering things from across the globe, so it'll probably all work out if we just believe hard enough.

Edit: Switching to electric cars doesn't prevent the pollution of microplastics from tires, btw, another massive part of climate change everyone seems to just be covering their eyes and pretending they can't see. We found microplastics in the clouds, ffs, nevermind in our own blood and bodies.

Nor do electric cars stop the glaciers that have already retreated way further than they should from retreating further. Where's all that methane gas, y'know, the more potent greenhouse gas than CO2, remind me, where is all that methane that was trapped in the ice going? Oh, right, it's feeding into the climate cycle, making things rapidly worse while we twiddle our thumbs and tell ourselves science will fix this for us, nothing else needs to be done.

Ah shit what are those goalposts doing way over there? I swear they were right here a second ago.

You are a fool if you truly believe we are moving in the right direction and do not require radical change to save our future.
