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.

Air New Zealand has abandoned a 2030 goal to cut its carbon emissions, blaming difficulties securing more efficient planes and sustainable jet fuel.

The move makes it the first major carrier to back away from such a climate target.

The airline added it is working on a new short-term target and it remains committed to an industry-wide goal of achieving net zero emissions by 2050.

The aviation industry is estimated to produce around 2% of global carbon dioxide emissions, which airlines have been trying to reduce with measures including replacing older aircraft and using fuel from renewable sources.

"Fuck the climate." - Air New Zealand

Pretty sure this has nothing to do with the new "conservative" NZ government either.

My guess is this is the underlying reason. Basically these companies set up the infrastructure for when governments would start to mandate this stuff, and they'd get a bit of nice press out of it. However, the fossil companies have found that you can basically confound all progress by the private sector just via the threat of rolling back climate legislation. This happened when the LNP government even just mentioned a nuclear plan which is just plain stupid.

I'm guessing by even stating it, Air NZ has gone one better than a lot of companies, which have conveniently "forgotten" about their goals. They'll get 20% of the way and declare that a success, but basically one company can't move until all of them move. We need to get the crazies out of government and out of opposition too.
