Most of us think of global warming as something that is bed for our planet. Every time you open a newspaper, there is an article about how the temperature on Earth is rising, causing floods, droughts and perhaps even earthquakes. Another common complaint is that winters used to be cold and summers hot, but now there is not much difference between them.
Scientists say that global temperatures have risen 0.6 degrees centigrade over the last 140 years. The question is, should we see this as something unnatural? Climate change is not something new. When talking about global warming, we should look at more than the last century. This is because Earth has been in existence for billions of years, and during that time there have been both warm periods and ice ages.
There havebeen computer predictions that in fifty years' time parts of Europe could be under water.With higher temperatures, the polar ice caps are melting and making sea levels rise.Yut many scientists say that the global climate is too complex for current computers to predict and that we should not beliewe these predictions.
The fact that the would is gettihg warmer should definitely concern us, but we should't exaggerate the problem. At the end the day, there is a strong possibility that the dangers are not as great as we fear.
