There are still a few people in northern Europe who think that global warming might not be such a bad thing. In Britain, where summer can sometimes seem to last a little more than a few weeks, many would welcome the idea of it getting a bit hotter. Unfortunately, things are not so simple. Global warming doesn't just mean that the world will slowly get warmer. Paradoxically, it could cause certain areas to get colder - a lot colder. The latest predictions are that northern Europe could even be plunged into an ice age. While areas of south-eastern Europe, such as Greece, would continue to get hotter and drier, Britain could find itself, in the winter months at least, surrounded by sea ice. The reason for this concerns the Greenland ice sheet. This is one of the biggest expanses of ice in the world - around 1,500km long and 600 km wide. It is so big that if it all melted sea levels would rise by 7 metres. Due to rising emissions of greenhouse gases, such as carbon dioxide from the combustion of fossil fuels, this ice sheet is melting at an alarming rate.
