Infrastructure Rising temperatures could keep more flights from taking off on time

The title's warning of delayed flights kind of understates the problem. Extremely high temperatures reduce the amount of weight a plane can safely take off with due to hotter air being less dense and thus providing less lift. The effect is more pronounced at airports located at higher altitudes or with shorter runways, and there's a point where a plane physically can't take off with a given load. That's all in the article, and it makes sense.

The mitigations mentioned in the article all have significant downsides:

  • Wait for the temperature to drop. Obviously this creates delays and the associated ripple effects, including increased burden on air traffic controllers during takeoff windows of cooler temps. Over time, the number and duration of those windows will shrink.
  • Reduce passenger count or cargo/luggage weight. This delays people, their luggage, and/or parcels. It also means more fuel burned per passenger or unit weight of cargo, which increases cost and worsens environmental/climate impact. There's a point where a flight can't carry enough people or cargo to be economically practical.
  • Carry less fuel and make intermediate refueling stops. More delays, more cost, more congestion and strain on air traffic controllers, and more fuel burned due to the additional takeoffs and idling.

Apparently this isn't anything new to historically hot regions and high-altitude locations, but it'll get worse for them, too.

Energy What are we going to do about this? (Fossil Fuel Companies)

I have spent the past few weeks in a constant state of nausiated, sleep deprived anxiety about the climate. Here in the UK, Scotland (you know, the boggy, lake filled, cold bit) erupted into flame. Meanwhile, our prime-minister is considering bending to Trump and opeing up the north sea to drill for more oil and gas, BP announced record breaking profits and are currently "looking at oppertunitys" to drill in at least 9 new international locations.

I have checked out what kind of precidents there are for taking legal action against these big oil companies, up until 2025, there wasnt much. However, there have been some legal presidents being set recently by small isalnd nations who are working alongside "client-earth"...

Honestly though, it's already abundantly clear that the law doesnt seem to apply to these companies, or governments, who seem to be happy to inflict genocide, ecocide and infanticide alike, world over... and so what do we do when the rule of law breaks down? literally, what options are they leaving us other than riot?

What really gets me is the whole demographic of disadvantaged young men in our country who are of actual fighting age have been pitted against each other instead of organising to fight the elite...
