Is global warming real?


These data from Greenpeace International suggest that it is. The concentration of Carbon Dioxide in the atmosphere is higher now than it has been in the previous 800 thousand years. What we are seeing now is not in the range of normal variation.

As greenhouse gases increase, so is global warming likely to take place, warming of the oceans, and rise in sea level. There will be major changes in local climates, and changes in the intensity and frequency of extreme weather events. Agriculture in many places will suffer; in some places people will have to migrate to survive.
