One Forecast We Didn't Need?

It's disturbing that budget airline, Ryanair, is forecasting it will get 100 million passengers, in the present financial year, as it comes out of lockdown (https://www.theguardian.com/business/2021/jul/26/ryanair-forecasts-100m-passengers-in-financial-year-as-bookings-soar-covid-19). Ryanair specialises in low cost, short-haul flights and its bookings are reportedly 'soaring'. 'Greenhouse gas' emissions will consequently be 'stratospheric', as the flights start. Short haul flights are too cheap (there is currently no tax on fuel). In addition, most carbon dioxide emissions are generated on take-off and landing. The world needs to find ways of reducing cheap, short hauls but they currently makes lots of money for operators.
