The Good Morning Britain presenter was responding to criticism on Twitter after he ridiculed the Swedish 16-year-old for attending a demonstration over global warming in Vancouver on Friday.
Morgan, who has previously performed a mocking impression of Thunberg on live TV, replied to photo the activist had posted: “Congrats. Looks like you’re having a lot of fun despite we ghastly adults ruining your childhood. Will you be reaching school again any time soon?”
The presenter was swiftly criticised for his sarcastic comment, which referenced a powerful speech Thunberg delivered at the UN in September in which she told world leaders: “You have stolen my dreams and my childhood with your empty words.”
Morgan later responded to the criticisms in another tweet, writing: “Oh, I don’t hate Greta at all.
"I find her passion admirable, albeit her rhetoric can be very hectoring and annoying.
“But I think she’s being used, and I worry about her more than her supporters seem to.”
Thunberg's emergence as one of the most recognisable faces in environmental activism has seen her come under attack from a range of prominent figures including US president Donald Trump and the owner of luxury fashion conglomerate Louis Vuitton Moet Hennesey.
