Opponents of climate activist Greta Thunberg have criticised her hypocrisy after learning she has been exhaling carbon dioxide for over sixteen years.

Carbon dioxide (CO2) is one of the chief causes of climate change and Greta Thunberg is known to have produced a steady supply of it throughout her sixteen years on the planet.

It’s thought that the Swedish activist produces as much as 2.3 pounds of CO2 every day, that’s almost half a metric tonne a year.

‘This is a clear case of left-wing hypocrisy. She’s here telling us all off for eating meat, using aeroplanes and consuming too much while she’s been breathing up a storm all this time,’ said one sad old man.

Greta has taken the criticism on board and will work with leading scientists on a filter that can be fitted to the nose to reduce the amount of CO2 she exhales.

This filter will be made available to everyone although it’s thought that it won’t work on people who don’t believe in climate change because they tend to be mouth breathers.
