As next month’s climate change conference in Copenhagen  draws closer, we are undoubtedly going to see the amount of online discourse on the topic continue to increase. The latest example comes from the British government, which last week released an interactive map showing the possible impact of a global temperature rise of 4 degrees Celsius (7 degrees Fahrenheit). An article  in the Guardian says the UK’s Met Office Hadley Centre  produced the map based on a recent study  that indicates, "such a 4C rise could come as soon as 2060 without urgent and serious action to reduce emissions." The newspaper also quotes the government’s chief scientist as saying that such a temperature shift would be “disastrous.”
Indeed, after exploring the map for just a few minutes, you see how devastating the consequences of a warmer planet might be. By zooming in and clicking and dragging with your mouse, you can navigate the map to see what could happen to different parts of the globe. Be sure to click on some of the plus signs, which give you a brief overview of an issue and the option to click to learn more and view sources of the research. The map, its creators say, displays the latest in peer-reviewed climate change research.
Looking around East Asia, you’ll see that some of the impacts listed include decrease in rice yield , extreme temperatures  in population centers of eastern China, and flooding caused by rising sea levels .
