Just pour in a hot beverage and see the effects of a 100-meter rise in sea level! Yikes! While this may not be everyone's cup of tea, the Global Warming Mug will certainly make a point! A great gift for the political pessimist or the enthusiastic environmentalist. This robin's egg blue mug detailed with the world map and a sinister snake of greenhouse gases surrounding may be just the everyday reminder we need to do what we can to protect the ozone layer! Great for any hot drink or soup. Ceramic mug measures 3.5" tall and 10" around.
