Imagine for a moment that planet earth is the Titanic. The supposedly unsinkable ship hit an iceberg, a split was gouged in its side which let in water and it slowly sank. Planet Earth is different to the Titanic but it's leaking carbon dioxide into the atmosphere which is gradually warming the atmosphere and beginning to melt all the frozen bits where water had been locked during the last Ice Age. Temperatures are going up. Not much but enough. It's the earth's equivalent of hitting an iceberg. We could patch the hole, stop pouring carbon dioxide into the atmosphere and stop the melting, but unfortunately the nations of the world, two of whom are absent and big producers, do not wish to patch the hole, do not give a fig and are happy to burn fossil fuels and warm the atmosphere. Luckily we won't sink all at once like the Titanic. The planet will just deteriorate and life as we know it deteriorate slowly. Humans will run away, find food, get flooded, escape, die or fight each other for the last bits and pieces. Please tell your children and all the young people what they have to look forward to because their parents cannot agree on trying to keep the thermostat down.
