Greta Thunberg has changed her Twitter description to 'bunny hugger' in an apparent dig at Boris Johnson who used the phrase at a virtual global summit on climate change.

The move came just hours after the British prime minister addressed the virtual climate summit held for Earth Day on Thursday.

During his speech Mr Johnson spoke of how climate action could help create jobs and aid in the global recovery from the coronavirus pandemic.

The prime minister said that 'it's vital for all of us to show that this is not all about some expensive, politically correct green act of bunny hugging'.

He added: 'This is about growth and jobs. And I think the president was absolutely right to stress that.'

Earlier in the day, climate activist Ms Thunberg, 18, posted a video to social media which said that the targets set by world leaders were 'very insufficient'.

She also said that leaders' 'bull****' on the issue was the biggest elephant in the room.

It is not the first time Ms Thunberg has changed her social media profile following comments from world leaders.

In 2019, then-president Donald Trump criticised Ms Thunberg the day after she became the youngest person to be named Time person of the year.

The former US leader tweeted: 'So ridiculous. Greta must work on her Anger Management problem, then go to a good old fashioned movie with a friend! Chill Greta, Chill!'

In response, Ms Thunberg changed her social media account to say: 'A teenager working on her anger management problem. Currently chilling and watching a good old fashioned movie with a friend.'

Ms Thunberg also made a similar move after remarks by Vladimir Putin.

After the Russian president said the then-16-year-old was a 'kind and very sincere girl', but 'poorly informed', Ms Thunberg changed her Twitter moniker to say she was 'A kind but poorly informed teenager'.
