Oh, I’m sure whatever is happening it is greenhouse gases, after all, there has never been an Ice Age before, has there?

[BAW]

Gore did it!! Wow!! He did such a good job of fixing global warming that we went clear over in the other direction . . to global freezing. The man Al Gore is a real talent! I nominate him for Secretary of the Environment!!! /sarc

Unlike warming, cooling is much easier to deal with. Under the oceans in many places in the world are enormous hydrate (Methane ice) deposits. Right now they are a major threat, because if they heat up even slightly, they will turn from ice to gas, releasing hundreds of thousands or more tons of Methane into the atmosphere all at once.

Methane is ten times stronger than Carbon Dioxide as a greenhouse gas. And while humans directly likely cannot cause global warming, popping one of these hydrate fields could very likely do it.

Atmospheric Methane has a half life of seven years before it oxidizes into Carbon Dioxide and water. So as a regular process, probably every 21-28 years, we would have to pop another hydrate deposit to keep the world from going into an ice age.

Another LITTLE ice age appears likely, and soon. Real ice ages didn’t just happen; the causes were cosmic in nature and with our solar system and neck of the milky way entirely stable at present, there is simply no reason to anticipate anything like that in the foreseeable future.

Global warming lost its charm because of stories like this. The new term is “global climate change.” That way the environmentalist are always right...

Carbon Dioxide (CO2) has little if any effect on the climate at levels within 10-15 times of what they are today.

THE ACQUITTAL OF CARBON DIOXIDE
by Jeffrey A. Glassman, PhD

ABSTRACT:

"Carbon dioxide in the atmosphere [historically] is the product of oceanic respiration due to the well-known but under-appreciated solubility pump. Carbon dioxide rises out of warm ocean waters where it is added to the atmosphere. There it is mixed with residual and accidental CO2, and circulated, to be absorbed into the sink of the cold ocean waters. Next the thermohaline circulation carries the CO2-rich sea water deep into the ocean. A millennium later it appears at the surface in warm waters, saturated by lower pressure and higher temperature, to be exhausted back into the atmosphere. Throughout the past 420 millennia, comprising four interglacial periods, the Vostok record of atmospheric carbon dioxide concentration is imprinted with, and fully characterized by, the physics of the solubility of CO2 in water, along with the lag in the deep ocean circulation.

Notwithstanding that carbon dioxide is a greenhouse gas, atmospheric carbon dioxide has neither caused nor amplified global temperature increases. Increased carbon dioxide has been an effect of global warming, not a cause. Technically, carbon dioxide is a lagging proxy for ocean temperatures. When global temperature, and along with it, ocean temperature rises, the physics of solubility causes atmospheric CO2 to increase.

If increases in carbon dioxide, or any other greenhouse gas, could have in turn raised global temperatures, the positive feedback would have been catastrophic. While the conditions for such a catastrophe were present in the Vostok record from natural causes, the runaway event did not occur. Carbon dioxide does not accumulate in the atmosphere."

The graph above represents temperature and CO2 levels over the past 400,000 years. It is the same exact data Al Gore and the rest of the man-made global warmers refer to. The blue line is temps, the red, CO2 levels. The deep valleys represent 4 separate glaciation/ice-age periods. Look carefully at this historical relationship between temps and CO2 levels (the present is on the right hand side of the graph) and keep in mind that Gore claims this data is the 'proof' that CO2 has warmed the earth in the past. But does the data indeed show this? Nope. In fact, rising CO2 levels all throughout this 400,000-year period actually *followed* temperature increases -lagging behind by an average of 800 years! So it couldn't have been CO2 that got Earth out of these past glaciations. Yet Gore continually and dishonestly claims otherwise. Furthermore, the subsequent CO2 level increases due to dissolved CO2 being released from warming oceans, never did lead to additional warming, the so-called "run-away greenhouse effect" that Al Gore and his friends keep warning us about. In short, there is little if any evidence that CO2 had ever led to increased warming, at least not when the levels were within 10-15 times of what they are today. -ETL

"The above chart shows the range of global temperature through the last 500 million years. There is no statistical correlation between the level of carbon dioxide in the atmosphere through the last 500 million years and the temperature record in this interval. In fact, one of the highest levels of carbon dioxide concentration occurred during a major ice age that occurred about 450 million years ago [Myr]. Carbon dioxide concentrations at that time were about 15 times higher than at present." [also see 180 million years ago, same thing happened]:

So, greenhouse [effect] is all about carbon dioxide, right?

Wrong. The most important players on the greenhouse stage are water vapor and clouds. Carbon dioxide has been increased to about 0.038% of the atmosphere (possibly from about 0.028% pre-Industrial Revolution) while water in its various forms ranges from 0% to 4% of the atmosphere and its properties vary by what form it is in and even at what altitude it is found in the atmosphere.

In simple terms the bulk of Earth's greenhouse effect is due to water vapor by virtue of its abundance. Water accounts for about 90% of the Earth's greenhouse effect -- perhaps 70% is due to water vapor and about 20% due to clouds (mostly water droplets), some estimates put water as high as 95% of Earth's total tropospheric greenhouse effect (e.g., Freidenreich and Ramaswamy, 'Solar Radiation Absorption by Carbon Dioxide, Overlap with Water, and a Parameterization for General Circulation Models,' Journal of Geophysical Research 98 (1993):7255-7264).

The remaining portion comes from carbon dioxide, nitrous oxide, methane, ozone and miscellaneous other 'minor greenhouse gases.' As an example of the relative importance of water it should be noted that changes in the relative humidity on the order of 1.3-4% are equivalent to the effect of doubling CO2.

Water Vapor Rules the Greenhouse System

Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many 'facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.

Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic).

Human activities contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate.

You are exactly right.

They’ll claim that the warmer temperatures are actually causing the earth to ‘react’ by cooling itself. The Ice Age will be seen as the earth simply overdoing it’s defensive cooling.

[LoneRangerMassachusetts]

Lets see, warmer temps mean more water evaporation in the Oceans which in turn produces more precipitation ( rain/snow.) Which in turn builds Glaciers which in turn cool the oceans which in turn cool the atmosphere.

You need to put together a better chain argument or a sarcasm tag. We get precipitation in summer and winter. It's not necessarily temperature driven. Water can transform from ice to vapor by sublimation. It's not neccessary for warmer temperatures. Water does needs cool temperatures to produce snow and ice. Warmer air can hold more moisture before turning to precipitation than cooler air. That does not lead to more snow and ice.

A more reasonable argument to describe a warming climate is to see less snow and ice. Any argument that global warming causes erratic climate and more now and ice is pure crap. It's rationalization by those hacks who depend upon global warming to levy their carbon tax credits.

[sionnsar]

Feet? I thought the UK had gone metric?

[D Rider]

The best part is, that when the oceans start to cool they will start sucking up CO2 faster than we could ever hope to make it.

We're gonna die!

Bush’s fault

Lemme see- is that jaded phrase supposed to be funny ?

Oh Maybe intelligent.

No?

Okay - how about trite and stupid. Yeah. That sounds about right.

[expatpat]

As if the fools could do either...

Right on. They are incredibly naive and arrogant.

[OCCASparky]

Oh, I’m sure whatever is happening it is greenhouse gases, after all, there has never been an Ice Age before, has there?

You mean that time about 12,000 years ago when there was over a MILE OF ICE sitting above where my house now stands? Now mind you, if you search for it on Google nothing will turn up...

Oh, Suzanna, don’t you cry for me!...”

[quickquiver]

So, based on the graph, and assuming the last “ice age” was 11-15,000 years ago, it would appear that we are indeed heading for another one (downslope of the temp variation curve) alright. The height of the next ice age will be in approximately 100,000 to 110,000 years from the present.
