During the past billion years, the Earth's climate has fluctuated between warm periodssometimes even completely ice-freeand cold periods, when glaciers scour the continents. In this article, climate scientist Kirk Maasch offers perspective on these historic changes, including the likely causes of the last great ice agewhich contrary to common knowledge, we are still in the midst of...
...The globally averaged surface temperature for the Earth is approximately 15 degrees Celsius, and this is due largely to the greenhouse effect. Solar radiation entering earth's atmosphere is predominantly short wave, while heat radiated from the Earth's surface is long wave. Water vapor, carbon dioxide, methane, and other trace gases in the Earth's atmosphere absorb this long wave radiation. Because the Earth does not allow this long wave radiation to leave, the solar energy is trapped and the net effect is to warm the Earth. If not for the presence of an atmosphere, the surface temperature on earth would be well below the freezing point of water...
NOTE: "We are still in the midst of" the last great ice age!
ManBearPig....I'm super ceral this time...
For all the nonsense we have heard about Global Warming over the past decade, a plunge into an Ice Age would be catastrophic. Even a “Little” Ice Age would result in massive starvation and economic depression. We need all the man made global warming that we can get.
My van?
It should be obvious to everyone that COLD starts ice ages.
Actually, it’s cow farts blocking the Sun!
After reading all the available material on the subject apparently the cause for GlobalWarmingCoolingClimateChange is:
1. Hummers.
2. Cow Flatulence.
3. And anything liberals don't like...
Cold, cold weather
Perhaps we should back up and say, what starts “COLD” ... then ... :-) ...

That is easy, less heat
Supposedly when JP Morgan was asked what he thought the stock market would do his reply was “It will fluctuate, son”.
Same goes for climate/weather. This much we know.
And then what is the start of less heat?
You see ... we’re looking for causes here and not merely definitions. It’s the cause that is the key.
I really think the problem is Al Gore and his need to make $100M in 8 years.
Going to causes ... as I pointed out in my last post, and to get to the point ... I would say it’s the sunspot activity, which affects some particles from outer space, which then affect cloud cover ... and then also volcanic activity. Besides sunspot activity, there is a variance in the sun’s heat output, too (which would be a different matter from sunspot activity).
That’s naming three causes there ... :-) ...

You left out cosmic rays and half of the heat of earth comes form radioactive decay of the core.
The particles from outer space were what I was talking about in terms of cosmic rays, which affect cloud cover, which is governed by sunspot activity.
I’m not sure how much the inner core heat relates to climate change, however.

I see “climate change” as a money making scam and government control mechanism. I see the temperatures of the earth as Climate.
