Would a temperature rise of a couple degrees really change the global climate.

In the last 10, 000 years the Earth's average temperature hasn't varied by more than 1.0°C. An increase of a few degrees won't simply make for pleasantly warmer temperatures around the globe. Even a modest rise of 1.5 °C could have dramatic effects. As a result the ice at the North and South Poles is going to melt, and sea levels and sea temperatures are going to rise. Both processes

lead to serious flooding and violent storms in many parts of the world. In other places there is going to be less rain, and the land may be turned into desert.

Scientists predict that continued global warming over the next 100 years will have a severe impact on many forests and other natural ecosystems and result in greater threats to human health.
