Common sense

World Global Warming? Has it occured? Well that all depends on your location or more precisely the location of your local temperature recording station. Believe it or not there has been tremendous human growth in the last hundred years. Some temperature stations have been affected by that growth. Where once a field of green now it is surrounded by concrete and steel. That concrete and steel has had a effect on the temp. station. It is called a "Heat Island Effect". This phenomenon describes urban and suburban temperatures that are 2 to 10°F (1 to 6°C) hotter than nearby rural areas.
Now to the thing that is real neat about this. The temperature's at those rural stations whose surroundings have not changed in the last hundred years has actually went down 1°F. All weather station recording data has been used by GW scientists, urban and rural.
