It is a known scientific fact that higher levels of greenhouse gases will lead to higher world temperatures, which appears to be happening now. Despite the winter of 2008/9 being one of the coldest for many years, the world has in fact warmed by an average of 0.74 degrees Celsius during the last 100 years or so. We are now faced with melting ice caps, as well as Earth's land-based glaciers. This in time will cause sea levels to rise, floods, and the submersion of low-lying islands such as Tuvulu and even the Maldives, as well as the world’s coastal cities.
