Global warming is spreading chaos across the world. The release of greenhouse gases has disturbed the divisions between the seasons, which means that characteristics of Spring, Summer, Autumn and Winter are beginning to merge. A good example of this is Poland.Before the exchange visit, the English pupils were warned to expect low temperatures (approximately -5 degrees celcius) and informed to pack clothes suitable for snowy weather however when they arrived they found that there was no snow rather the weather was very similar to back home in England, with mild temperatures of approximately 9 degrees celcius.This is very rare in Poland and 2007 has been one of the mildest winters the country has seen for many years. It is a consequence of global warming and means that as Winter is beginning to resemble Spring, it is becoming hard to distinguish between the two seasons, this is known as disturbed division between the seasons.
The weather is becoming more severe and natural disasters, such as Hurricane Katrina, which devestated New Orleans in 2005, are becoming more frequent. Disturbances in the weather pattern are a consequence of the rise in the global temperature, which has lead to the melt down of the Polar Ice caps. This has caused a rise in sea levels and in some places the temperature is rising, whereas in others the temperature is rapidly decreasing and in the UK, there is even the threat of an ice age.
