But it also shows a clear multi-decadinal rise in the temperature. The long-term rise is only about 0.15 C/decade, so it%26#039;s not valid to arbitrarily select any specific 5 or 10 year period and say %26quot;see it%26#039;s warming/cooling%26quot;.
Climate, according to the World Meteorological Organization, is defined as the average of weather over a 30 year period. This has been a long accepted international standard (not something arbitrarily selected to prove global warming), so anyone claiming global cooling based on the past 10 years is clearly not adhering to scientific norms for determining such a phenomena. http://www.crh.noaa.gov/grr/climate/norm...
global cooling...(the next ice age), wont%26#039; happen until the earth is almost completely covered in water. Then the suns rays will not have a surface to absorb heat into and the water will largely reflect off of the oceans. The light that doesn%26#039;t reflect will cause violent supermassive hurricanes that last for months, then eventually years... Then the entire earth basically becomes a big popscicle for the next 5000 years..that%26#039;s when sea level falls because of a shift in the global hydrologic cycle: water is evaporated from the oceans and stored on the continents as large ice sheets and expanded ice caps, ice fields, and mountain glaciers.... and until the poles reform into enough accumulated ice mass allowing more land mass to be exposed again, the earth won%26#039;t begin warming. There would be very few inhabitable places left on earth during this time.
We are basically sitting on top of the beggining of the next ice age.....but it could be either starting now, or 10000 years from now.... nobody really knows...all they have is prediction based on the last 400k years of data. See below.

The faster we warm the earth, to melt all the ice and raise the oceans, the faster we begin the next ice age.

I%26#039;d say watch the atmospheric measurements taken 2 weeks prior to 2weeks after the Olympic games in China. Of most interest would be water temps in the upper Pacific between China and Canada. This may prove the 9-11 aftermath of evaporational increases as eluded to in the pbs documentary. It may also prove the cloud ,or cloudless claims in that theory. PBS fan.
