Celebrities who back the Extinction Rebellion protests have admitted their "hypocrisy" in an extraordinary open letter.
More than 100 big names have urged the media to focus on the "real story" of climate change, rather than their part in the protests.
Among the signatories are Benedict Cumberbatch, Spice Girl Mel B, Steve Coogan and Glastonbury Festival organiser Emily Eavis.
The letter says: "Dear journalists who have called us hypocrites. You're right.
"We live high carbon lives and the industries that we are part of have huge carbon footprints.
"Like you, and everyone else, we are stuck in this fossil-fuel economy and without systemic change, our lifestyles will keep on causing climate and ecological harm."
They said they can't ignore the call of young people like Greta Thunberg to "fight for their already devastated future", even if it means they themselves are "in your firing line".
The letter continues: "Life on earth is dying. We are living in the midst of the 6 mass extinction."
It ends: "We invite all people with platforms and profiles to join us and move beyond fear, to use your voices fearlessly to amplify the real story.
"Thousands of ordinary people are risking their freedom by taking part in non-violent civil disobedience.
"We've been inspired by their courage to speak out and join them. We beg you to do the same."
Emma Thompson was one of the celebs criticised after she flew 5,400-miles from LA to attend the protests in London earlier this year.
A flight from Los Angeles International Airport to Heathrow generates around 1.67 tonnes of CO2.
Addressing the criticism, a spokesperson for Emma said: "She had to fly home at any rate, it was just earlier than she thought she could have.
"At the moment, that is our only available and practical means of trans-global travel."
