Quote from IShopAtPublix:
Let me ask you this question: Do you continue to use your computer and believe in the existence of the solar systems knowing full well that people used to believe the earth was flat?
Why did I ask this weird question? Frequently a bunch of numbnuts parade around here and cite how scientists were concerned about global COOLING in the 1970s as "proof" that global warming is a hoax.
Just because scientists were wrong about something at one time, does not mean they are wrong now. Science is a continuous learning process that is self-correcting. I use my computer knowing full well that at one time ideas of scientists concerning aviation, electricity and even gravity were highly demented. Also, doctors used to bleed people to "cure" them. That does not mean medicine is a fraud.
A lot has changed since the 70s. The world consumes a lot more fossil fuels and there are a lot more people living on the planet. More cars, more stuff, less forests to absorb it.
Polar caps are melting this is an indisputable fact. It is not that Earth is heating up that is troubling it is the RATE at which it occurs. Processes that should take thousands of years take a lot less.
If you believe "the conservative" point of view, all the scientists who believe in man made global warming are a bunch of tree hugging lunatics who got into a frenzied state and decided to brainwash the world(as opposed to "honest" scientists working for good folks at exxon mobil who are trying to set us straight).
What is more believable(and what actually is true) is that certain groups of people have a vested interest in making sure the world cranks out and consumes as much stuff as possible. And fox news/talk radio being the conduit of big business puts those ideas into the heads of simpletons.
If you are an industrialist cranking stuff out in china or exxon mobil you don't give a shit about polluting or global warming you need the gravy train to move forward.
This whole post just affirms that both sides of the argument have their own agendas.
So how about this - forget all that stuff and let the facts speak for itself.
FACT - the IPCC identifies water vapor as THE major greenhouse gas.
FACT - the IPCC does not go into the effects of water vapor in its studies, and instead attributes ANY and ALL warming to CO2.
Why?
FACT - a 1996 graph from the IPCC clearly reflects the so called "Viking era" and also reflects the Little Ice Age.
FACT - the 2001 graph, which Gore used, and the IPCC uses to this day, has been sanitized and no longer shows these periods.
Why?
FACT - the relationship between CO2 and MMGW is in dispute, but the relationship between solar radiation and Natural GW is not.
FACT - the IPCC refuses to consider that increasing solar radiation causes increasing water vapor as the cause of GW.
Why?
FACT - Past levels of CO2 as touted by the MMGW crowd were taken by proxy for the period up to ~ 1950- ice core sample - but present levels are determined by air samples.
FACT - but air samples are available from as far back as the early 1800's that show CO2 levels as high as 550 ppm, which shows the claim that we have the highest levels ever to be false, yet the IPCC refuses to use this data.
Why?
