It is fairly unbelievable because what's been stated are fairly simple and damning matters of fact. If you followed them up... your opinion really should of changed.
One major reason is that the tempeture measuring records like the tempeture stations methods were VERY problematic and unscientifically done. They didn't account for ubran sprawn and urban warming effect, stations were dropped and re-added etc... the oceans were generally ignored. Satellite data is the only good form of tempeture measurement. Which has only been used for like... well 10-15 years.
All the science is based on very poor methods of unrepresentive tempeture measurement. In reality we know... pretty much NOTHING. Except that there has been no global warming trend for the last 10-15 years. Yet people are 100% sure global warming is happening.

I think most of the concern about global warming comes from data which goes back a lot longer than those 15 years. Climate records from the past ~500,000 years show that there is a clear correlation between CO2 increases and temperature increases. Most current climate research is focussed on how the Earth will respond IF the temperature does increase (i.e sea level rise, ocean circulation and heat distribution ect). It's clear from the graph (below) that temperature and CO2 are related and according to the data, CO2 increases precede temperature increase. However, the error in the measurements is more than large enough for the opposite to be true. So for me the biggest question we need to solve right now is which of the two cases is true.
I'm inclined to lead towards temerature being the driving force behind CO2 increases as there is a clear mechanism we know off that allows for this (orbital variations which correspond to the cycles seen in the graph raise the Earth's temp which in turns causes the oceans to release more CO2 into the atmosphere). As far as I know there is no mechanism which could account for CO2 increasing before temperature. If that is the case the only issue left to be resolved is how large an impact the CO2 had as a feedback role in further rasing the temperature. If the CO2 did act as a feedback mechanic then that presents problems for us as our CO2 levels are currently far higher than they have ever been over the past 500,000 years.
