They report in the journal Climatic Change that, if humans continue to burn fossil fuels at an accelerating rate, and as average global temperatures creep up by the predicted 4 °C above historic levels, then on the hottest days, between 10 % and 30 % of fully - loaded planes may have to remove fuel, cargo or passengers before they can take off: either that, or flights will have to be delayed to the cooler hours.

Focusing on decimal degree C. changes in global temperature is the tantamount to focusing attention away from the coming climate changes that will cause floods, droughts, dust storms, high winds and other extreme weather events and the difficulty of predicting where, when, and which kinds of weather related problems people in the near future will be experiencing.
