By 2050, extreme heat could ground 23 times more airline passengers than today

Visual form

Bar Chart: three time-point range columns for airline passengers grounded by extreme heat.

Layout / body structure

The chart reads left to right from today to 2030 to 2050. Each time point is shown as a vertical range marker, with boxed callouts explaining the multiplication versus today’s disruption level.

What is being compared

It compares the annual number of passengers affected by heat-related airline groundings across today, 2030, and 2050 under a no-adaptation case.

Measurement system

The measure is passengers affected per year, shown in thousands. Each time point is a range rather than a single estimate.

Visible structure inside the graphic

The current range is short, the 2030 range is much taller, and the 2050 range is taller again. The future callouts translate those range increases into multiples of today’s grounding level.

Main takeaway from the visual

The chart shows that extreme heat could turn from a limited current disruption into a much larger aviation operating risk by midcentury if adaptation does not occur.

Key standout values or extremes

Today is 4 to 8 thousand passengers affected per year, 2030 is 16 to 75 thousand, and 2050 is 40 to 185 thousand. The headline multiplier is up to about 23 times today’s level by 2050.

Controls / sequence, when applicable
