The earth's climate has seen many changes in its 4.55 billion years.

FloodDid you know? Serious floods around the world, which used to occur every 100 years are now occurring between every 10 to 20 years. 

Why? Because warmer air temperatures lead to more evaporation, which eventually causes more heavy rainfall.

Unfortunately it’s not just happening in the UK. The USA suffers from hurricanes every year, but the number and intensity is rising:

Between 1975 and 1989 there were 171 severe hurricanes in the USA. Between 1989 and 2005 there were 269 severe hurricanes in the USA.

Hurricane Katrina in New Orleans last year was the costliest and one of the deadliest hurricanes in the history of the United States. Hurricanes develop as a result of air warming up over warm seas, causing the air to rise rapidly and develop into major storms. The warmer the sea, the warmer the air, the worse the hurricane.

Coastal Flooding
The ice caps at the North Pole (The Arctic) and the South Pole (The Antarctic) are slowly melting and this is causing the sea levels to rise. The Intergovernmental Panel on Climate Change has estimated that sea levels may rise by 40 cm over the next 100 years, but some scientists estimate the rise could be much higher. This shows that we don’t really know what’s going to happen, but we are sure that something is and the effects could be dramatic:

If the sea levels continue to rise, many countries and cities could be flooded by the sea. Bangladesh is one example (they already suffer from severe annual flooding); nearer to home, cities like London, Bournemouth, Cardiff, Newcastle, Carlisle and Edinburgh could also be at serious risk.
