Why are people so up in arms about the so called global warming? We have been able to take temp readings at Mt Kilamonjaro in Africa for years and it is colder now then it was 20-30 years ago at its peak. Its lost most of its snowcap do to deforestation but its still colder. Many people dont remember but in the 70s many scientists were worried about global cooling. Another science experiment the biodomes 1 & 2 showed how little we really know about how the earths surface is warmed and cooled. I personally think there is no real evidence that shows we are causing any climate change.

Brad, you are a moron. Stop listening to Rush Limbaugh.

Alan, Brad makes sense. Western education automatically assumes a 'uniformitarian' view of the World, a concept that change is gradual over long periods of time. As a consequence, sudden or extreme changes are considered abnormal by most of society. Yet even a cursory examination of climate records reveals variations in centuries past that are far faster and more severe than anything we are experiencing today.

Humans are naturally selective in what we notice. For instance, selectivity occurs when, after being introduced to someone, you seem to meet them frequently. They were always there, but just not part of your "noticing." Similarly, the media and the public have started to "notice" extreme weather, glacier melting, sea level rise, etc. more because alarmists tell us that an increase in such events is a precursor to the coming 'climate crisis'. Since people are on the lookout for such trends they seem to be accelerating even though recent quantitative studies demonstrate they are not (NRSP 'allied scientist' Dr. Madhav Khandekar has shown this clearly in his studies for the Alberta government, for example).

Phenomena such as severe weather events are now often presented as unusual or unique: it was the highest or lowest temperature, rainfall, etc., 'ever.' What is referred to is the barely century-old instrumental data-based official weather record, an inadequate sample of the Earth's five billion year history. Long term geologic records indicate much greater and more rapid changes occurred long before civilizations started.
