Global warming

I was going through the new york times and i came across this article about global warming and it made me want to read more about it. Last semester i took a meteorology class and we talked about global warming alot. This article talks about how each year the earth gets warmer and warmer from all the carbon dioxide built up in the air. Countries like Africa accounts for less than 3 percent of the global emissions of carbon dioxide from fuel burning. But they face biggest risks from drought and disrupted water supplies. As the oceans fill with water from melting ice sheets, it is the crowded river deltas in southern Asia and Egypt, along with small island nations, that are most at risk. Eventually all the countries will be under water. The richer countries like United States don't have to worry about it so much now for at least couple more generations but they have started to build desalination plants, can work far from the sea, purifying water from brackish aquifers deep in the ground in places like New Mexico. Bush signed a treaty stating that countries will help others for cost of adaptation if they have to because of climate changes. It is clear that the rich countries are far ahead of the poor ones in adapting to climate change. But they can never be to sure. I learned that if they dont start taking percautions now and start worrying about it then sooner or later we can all end up under water.
