Greenpeace extends its sincerest condolences to the families of the victims of yesterday's heinous attack on the office of the satirical magazine Charlie Hebdo, in Paris.

Charlie Hebdo cartoonists were fervent advocates of democracy and of fundamental liberties, such as freedom of speech. These values are not just shared by Greenpeace, they are part of who we are.

Few people living outside France may be aware that many of the cartoonists were also long-standing advocates for the environment.

Years ago, the cartoonists Cabu and Tignous generously provided their drawings, particularly to call attention to the problem of climate change. And some of the cartoonists stood with Greenpeace 30 years ago when our ship, the Rainbow Warrior, was sunk by the French Secret Service and a Greenpeace photographer was killed.

The irreverence with which Charlie Hebdo approaches its topics may not be to everyone's taste. But the savage act that yesterday engulfed Paris demands universal condemnation.

For over 40 years, Greenpeace has been campaigning to protect the environment and all who share it, to promote peace and to rely on non-violence. We support all those who stand up to defend freedom of expression, respect for others and tolerance.

In memory of the victims of yesterday's attack we are reproducing here a small number of cartoons from the book 'Dessins pour le climat' – cartoons for the climate.
