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:

Air New Zealand becomes first major carrier to drop climate goal (www.bbc.com)

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.

Please read the article. They had previously committed to much more ambitious goals than most airlines to begin with, and (as agreed by experts) are limited now by their government, which has been called New Zealand's most conservative government in decades. Also limited by low supplies of better fuel and slower than expected output of newer model planes

Side note, not from the article: as the new hyper-conservative leader of New Zealand was Air New Zealand CEO, it wouldn't be surprising that they aren't especially unhappy. "Oh noes, guess we can't fix it now. Ohhh welllll"

Yes, exactly. This is from the article:

In 2022, Air New Zealand adopted a 2030 target to cut its emissions by almost 29%.

It was much more ambitious than a 5% reduction goal over the same period set by the global aviation industry.

The worrying thing is not that they can't meet their goal (they probably knew it was optimistic), it's that they didn't announce a new target. They said they are working on one, but why not work on the new goal then make the announcement?

A good reason would be to get ahead of the bad press and control the narrative. Even something as minor as a bad turn of phrase in an internal e-mail could force them to make a press release early, in that case becaues of the risk of it being stripped of context and leaked to the press by corporate spies or well-meaning whistleblowers in a way that looks way worse than a promise to get around to it later.

Not sure how likely this is compared to it being a fig leaf over cancelling the target altogether.
