When it’s pushed into as many stories as it can.

Like global warming/climate change/rising sea levels.

The weather forecast for the US city suggests temperatures could reach 120F (49C) on Tuesday.
That is higher than the operating temperature of some planes.

American Airlines announced it was cancelling dozens of flights scheduled to take off from Sky Harbor airport during the hottest part of the day.

The local Fox News affiliate in Phoenix said the cancellations mostly affected regional flights on the smaller Bombardier CRJ airliners, which have a maximum operating temperature of about 118F (48C).

The all-time record for temperatures in Phoenix is just slightly higher, at 122F, which hit on 26 June 1990.

The cancelled flights were scheduled to take off between 15:00 and 18:00 local time.

Why can’t planes fly?

At higher temperatures, air has a lower density – it is thinner. That lower air density reduces how much lift is generated on an aircraft’s wings – a core principle in aeronautics.
That, in turn, means the aircraft’s engines need to generate more thrust to get airborne.

It’s a well-known problem – a 2016 report from the International Civil Aviation Organization (ICAO) even warned that higher temperatures caused by climate change could “have severe consequences for aircraft take-off performance, where high altitudes or short runways limit the payload or even the fuel-carrying capacity”.

Those problems are why many countries in the Middle East, and some high-altitude airports in South America, tend to schedule long flights for the evening or night, when it is cooler.

Bigger aircraft like Boeing 747s and Airbus models have a slightly higher operating temperature, and have not been affected by the heat in Phoenix.

An American Airlines statement provided to The Arizona Republic newspaper said those jets should be fine up to 126-127F (53C) – just a little higher than what is expected.

    The Liberal Soros ass-sucking MSM machine is ripping out fake news at phenomenal speed. Their main objective: “Destroy Trump”. Hopefully it will have just the opposite effect: “Love Trump more”. Georgia election: Republicans 1, Dumbocrats 0.

    What they are not telling anyone is that these temperatures are common for
    a number of cities in Arizona, California, and Nevada. This shit happens
    EVERY Summer! Oh, and I love the way they tried to give the story some
    added impetus by delivering a grade-school science lesson on air density.

    I live in the High Desert of Southern California, so I know a thing or two about
    heat. The last few days here have been fucking BRUTAL and we are only talking
    about 103 or 104 degrees F. This is the scope of their argument: Like Al Gore,
    they are mistaking weather for climate! Anyone this fucking stupid should not
    be allowed to control national policy.

    Bogside, I do believe you have mastered my theories on the dynamics of politics.
    We are dealing with infantile brats who are too stupid to understand that words
    (And actions) have consequences. This is why the lesbian communist in the
    Mao Jacket got her ass stomped like a Narc at a biker rally. This is why
    the Demoncrats have lost more than 1,000 seats in the last 3 or 4 campaign
    cycles. One their party came out as full blown Marxist, (Obonzo) the people
    rejected them flatly! Pajama Boy was left oinking from the boinking.

    We are all seeing push back against the leftist agenda, and it will continue
    into the 2018 mid-terms.
