Tundra and permafrost cover about one fifth of all land. • Oceans are huge sinks of carbon dioxide . The solubility of water is highly temperature dependent – the colder the temperature, the higher the capability of water to dissolve carbon dioxide. As ocean temperatures rise, some of the stored carbon dioxide is released back into the 04/20/11 6 Consequences of Global Climate Change 1. The air temperature close to the earth’s surface increases , whereas the stratosphere cools . It’s estimated that the earth could warm by between 1.4 and 5.8 C by the end of the century. During the last ice age, the surface temperature was 5 C colder than it is today. 04/20/11 7 2. The ocean water gets warmer . Water circulation in the oceans can be affected causing the Gulf Stream to weaken and could cause the temperature in much of Europe to drop. 3. Ice caps in northern latitudes and Antarctica to breakup and melt . This can reduce the amount of sunlight that is reflected back to the sky, a rise in sea level burying small islands in the Pacific and in low lying countries such as Bangladesh and the Netherlands, millions of people could be displaced. Many coastlines and beaches including the USA could be lost....
