All those damn horses I guess:roflmao

I think global warming is a threat, it will change the way we live. Maybe not so much in the 1st world but certainly in the developing world, creating a deluge of climate refugees coming our way. Parts of the world will become barren, hopefully some other parts more fertile.
Though man's hand in it is I think more or less proven, it has happened before.
I know. I'm not feeling personally threatened. I've reduced the size to match my honourable debate partner.Quote:

The findings prove that the world experienced a Medieval Warm Period between the ninth and 14th centuries with global temperatures significantly higher even than today.
X, thanks for the gristmill reference... there's lots of interesting stuff referenced there that gives me pause for thought.
My problem is it doesn't take very much Googling to find an equally impressive list of counterarguments from people with equally good credentials as far as I can tell... I listed a couple earlier, here's another "Just how much of the Greenhouse Effect is caused by human activity?" Quick Orange's reference is seemingly valid as well and my earlier references contained similar findings.
So which argument(s) are correct? Different (seemingly reputable) scientists have differing data and cause/effect theories which lead to different conclusions.
The question in my mind remains... is mankind primarily responsible for the current global warming situation or are we just a minor contributor??? :shrug:
How about this then: Erring on the side of caution, if we reduce the greenhouse gasses which are suspected to cause climate change, we should see a decline in the rate of radical change. Experimentation seems to be the only solution to our impasse and I suggest we take it up.Quote:

I don't know if any of you are familiar with the evolution that is dirt bike engines, but up until about 2001, almost all serious race bikes we two strokes. They're noisy, burn gas like crazy, and pollute quite a bit. Following pressure, the big mfr's did research and development into 4 stroke race engines and what used to be the dog of the race is now better than 2 strokes! They're more efficient, don't burn oil, and kick just as much ass for the same price.Quote:
