Questioning climate science

[coykiesaol]

I would like to devote this thread to discussing the science behind the conclusion that the emission of greenhouse gases by man has lead to global warming.

The main evidence supporting the claim above:-

1. Greenhouse gases maintain the atmosphere near the Earth's surface at level of about 33 degrees warmer than would be expected from simple radiation calculations.

2. The globe has warmed over the last 100 years by about 0.75 Degs C

3. The following greenhouse gases have increased in the atmosphere and can be attributed to man's emissions.
Carbon dioxide by 40 %
Methane by 150%
Nitrous oxide by 16 %

4. These emissions are have increased the global temperature enough to produce knock on effects:-
a.Evaporating more water vapor which also adds to the greenhouse effect.
b. Shrinking ice cover leading to reduced albedo.

The challenge for those who don't accept the above is make a reasonable case that man has not contributed to the global warming that has occurred over the last 100 years

Before beginning, it's nice that you want to devote a thread to the science. Unfortunately, it's been done, and I'm not going to start from scratch all over again. There are plenty of threads in Environmental and Alternate Energy that discuss the science....with some politics and other topics inevitably weaseling their way in...

You'll notice I've bolded one of your statements?? Care to offer some proof of the 40% increase in CO2 as being anthropogenic?

Supporters for GW/ClimateChange, whatever, are drowning in their own misinformation! But it is fun to read... although very troubling to see so many that have been duped and how we came sooo close to having to fund the entire lie that is Cap and Trade.

The spherical nature of the earth has yet to be conclusively proven.

This fellow Copernicus purports to be a scientist, but this notion of a heliocentric universe is patently absurd, and ultimately unprovable.

His efforts are nothing more nor less than an effort on the part of the intellectual elites to seize control of every aspect of human life. Their first step is to denigrate humanity by "proving" with a logic (which they invest with the powers of a deity) that Earth is not the center of the universe, and therefore Man is not the pinnacle of God's creation.

Climate change ?
It would be more surprising to hear the climate is static.

Man made ?
I'm not convinced.

If we now can change the wheather, when are we going to make it summer year 'round? Winter and the nessecary heating of house/shop is no longer financially feasable. More poeple die from cold than summer heat, and so is another reason to end winter. Those who like to ski can go to the mountains or the antartic for that.
The only reason for this 'climent change' crap is people control. The carbon content of the air is natural and the 'concencess' is designed to get taxpayer dollars! The computer examples of future wheather is flawed. The data for past wheather patterns fed into the computer can't reproduce those past realities! If the past can't be confirmed, how can we allow ourselves to be consigned to future slavery by the same false data? The 'gores' of the world stand to make millions from this lie. And Gore already has profited.

The Apollo project is often cited as an example of American ingenuity, imagination and vision.

But how do we know it actually happened? Where is the concrete proof? How do we really know that it was not staged by the media elites to weaken support for the battle to liberate Southeast Asia from the oppressive forces of communism?

Quite possible.

Scientists have theorized that Earth has seen as many as 6 'ice ages/glacial periods'.
If that's true, change is the norm and we may be overestimating our power over this planet. Otoh, fossil fuels are a messy business. Take a look at the tar sands..... yuck.

...change is the norm and we may be overestimating our power over this planet...

Of course people overestimate their importance to the world, in direct proportion to their egos, e.g. the persecution of Galileo, Copernicus and anybody questioning the geocentrist tenets of the medieval church.

Imagine the sheer hubris of James Ussher, Archbishop of Canterbury, who in 1654 "determined" the date of the world's creation by assigning an arbitrary period to all the "begats" he could count in Genesis...and if you didn't buy into it, you were guilty of heresy and could be burned at the stake. One can easily imagine Algore wishing he had the power to punish heretics. Cap and Tax would have been nothing so much as punishment meted out to those who value Western humanity's hard-won freedom over blind faith in a religion, which is what anthropocentric global warming (now repackaged as anthropomorphic climate change since claims of warming are no longer credible among thinking people) amounts to. Like any other religion, its leaders must have an unshakable belief in themselves as prophets and saviors. Anybody with enough ego to present himself as inventor of the Internet is by definition as much a charlatan as Ussher.

I'm frankly surprised that global warming would even be a subject of discussion on a forum whose membership presumably consists of technically informed people. But then, I once worked with a qualified milling machine operator whose delusion was that he had a gizzard, like a chicken, rather than an esophagus like other people. You couldn't argue with him. He'd have gone for the global warming scam in a heartbeat.
