Effects of Global Warming: Sea Level
We have seen that an average drop of just 5 degrees Celsius over thousands of years can cause an ice age; so what will happen if the Earth's average temperature increases a few degrees in just a few hundred years? There is no clear answer. Even short-term weather predictions are never perfectly accurate because weather is a complex phenomenon. When it comes to long-term climate predictions, all we can manage are educated guesses based on our knowledge of climate patterns through history.
