Zach Wichter wrote an article in the New York Times (June 20, 2017) entitled “Too Hot to Fly? Climate Change May Take a Toll on Flying.”
He pointed out that when temperatures get too high, the aerodynamic that allow planes to take off is negated.
4 years ago, Aviation website explained:
“On a hot and humid day, the aircraft will accelerate more slowly down the runway, will need to move faster to attain the same lift, and will climb more slowly. The less dense the air, the less lift, the more lackluster the climb, and the longer the distance needed for takeoff and landing. Fewer air molecules in a given volume of air also result in reduced propeller efficiency and therefore reduced net thrust. All of these factors can lead to an accident if the poor performance has not been anticipated.”
In 2021, flights were grounded due to intense heat:
And in Phoenix, Arizona, it was stifling and excessive heat which grounded flights:
“Airbus and Boeing jets are able to operate at higher temperatures, but performance may still be impaired by heat. Earlier this month Hainan Airlines decided to delay the departure of its flight from Las Vegas to Beijing for the summer, because of the capacity restrictions imposed by high afternoon temperatures.
The Chinese carrier has switched the departure time from 2.10pm to 1am. Flight HU7970 will take off in the early hours until the end of October.”
When we take a round trip journey from New York to London, our flight costs the Arctic three more square meters of ice. See:

Current situation in the Arctic:
We have seen the increase of permafrost melting in Arctic areas of Russia. The most alarming consequence is illustrated by the oil spill a couple of years ago:
Food security is deteriorating due to many factors, but a major one is climate change.
Economical disaster will hit farmers who remember perfect conditions for their produce in mid latitude countries. They will have had a good living during their lifetime, but now will see their land turning to desert. It will be a Grapes of Wrath scene on a massive scale.
Yet emissions continue to rise and the consequences are what we know already.
The classification of countries will change as mid latitude countries lose out due to climate change. As some economies shrink, so others will grow, but globally the world is suffering due to high use of fossil fuels in industrial settings.
Apparently Karl Marx can help us out of the mess we are in if our minds are open to his wisdom, as represented to us in a recently written book:
