Celebrities including Stephen Fry, Jarvis Cocker and Emilia Fox have taken part in a short film to "show the love" as part of a campaign on climate change.
They have joined actors David Harewood, Alison Steadman, Meera Syal , Dragons' Den star Deborah Meaden, presenter Dermot O'Leary and Raymond Blanc to use Shakespeare's famous Sonnet 18 on love, Shall I compare thee to a summer's day? to highlight the Earth's changing climate.
The film, directed by Stuart Rideout of Ridley Scott Associates, ends with a message urging the public to join efforts to tackle climate change.
It is part of the Show the Love campaign, which aims to raise the profile of climate change and make Valentine's Day green by encouraging people to wear green hearts and discuss the things they love that could be lost to rising temperatures.
The week-long campaign by the Climate Coalition of more than 100 organisations including Greenpeace, Oxfam, RSPB, Cafod and WWF, comes in the build up to key United Nations talks in Paris in December which aim to secure a new global climate deal.
