1.5 degrees is when the tipping points start to tip.

Fun fact: the planet has been at +1.5℃ for the last 14 months.

The reason why we aren’t officially at +1.5℃ is because the official designation is a political one, which requires some insanely long time at +1.5℃ - usually on the order of 8-20 years, depending on the org - before it can be said that we have “breached +1.5℃”.

Politicians are morons in the pockets of the Parasite Class.

One of the really popular subs - with hundreds of posts per day - cracked down on bots and nothing was posted for two days afterwards. Can’t recall which sub it was, It was WholesomeMemes. I caught wind of that a few days later and it was truly a ghost town. Even now they’ve only got something like 5% of their pre-bot-ban traffic back - about 4-6 posts a day.

Missiles require an inordinate amount of thrust for their weight to remain airborne, due to the lack of large(ish) wings. Because the aircraft is already moving forward at high speed, the missile would lose considerable altitude (if fired backwards) before it would acquire sufficient velocity on it’s own again.

IIRC there have been missiles that could be targeted against aircraft behind the one launching the missiles. They would lock the missile against the pursuing aircraft, fire it forward, and the missile would arc around to go after the other aircraft.

Now bullets on the other hand, can come in supersonic versions. Unless the aircraft is moving at Mach speeds (and you always slow down to dogfight in order to make turns survivable), a supersonic bullet fired backwards will have sufficient speed in that direction to reach the other aircraft without too much aiming difficulties.

Beyond bullets: AFAIK there have been experiments in launching chaff (metal filings) such that it gets ingested into the pursuing aircraft’s engines, causing damage that way. But from what I recall there was too much of a risk of other aircraft in the vicinity and below that engagement also getting caught in the falling chaff. Still good for enemy aircraft, not so much for your own teammates.
