The currents and levels affect different areas differently. The fact is, the icebergs at the caps are melting. The average temperature of the earth as a whole has increased.

You know, for every fact about Global Warming, there is a myth:

While ground-level temperature measurements suggest the earth has warmed between 0.3 and 0.6 degrees Celsius since 1850, global satellite data, the most reliable of climate measure- ments, show no evidence of warming during the past 18 years.

Even if the earth's temperature has increased slightly, the increase is well within the natural range of known temperature variation over the last 15,000 years. Indeed, the earth experienced greater warming between the 10th and 15th centuries - a time when vineyards thrived in England and Vikings colonized Greenland and built settlements in Canada.

While atmospheric carbon dioxide has increased by 28 percent over the past 150 years, human-generated carbon dioxide could have played only a small part in any warming, since most of the warming occurred prior to 1940 - before most human-caused carbon dioxide emissions.
