"Each year, the country that hosts the UN's conference on climate change dishes out a wad of cash on a logo. The usual request to graphic designers is to provide something cosy. Something planetary. We-are-the-worldish. Whether all the hugginess works is another matter," writes AFP science, health and environment coordinator Richard Ingham. "Take the logo unveiled this week by France, where 195 countries are supposed to seal a historic pact in December. Is it a leaf nibbled by an ant? The Eiffel Tower, melting under a scorching Sun? Or a drop of biofuel, representing a greener, cleaner future?"
