In 1958, American scientist Charles Keeling took direct measurements of carbon dioxide, and soon afterwards he connected the gas with global warming. Keeling’s findings were the first to suggest that human beings could be contributing to the greenhouse effect and global warming. Yet today debates continue to rage over the causes of global warming – and indeed whether it’s even happening at all.
Notwithstanding these arguments, environmental organizations such as Greenpeace, the World Wide Fund for Nature (WWF) and the Natural Resource Defense Council (NRDC) have worked on countless campaigns to highlight the issue, raise awareness and motivate people to act. Here we look at 15 of the most creative and convincing global warming awareness ads.
