Global Warming Misnomer

12/20/2011 5:59 PM

Listening to a program on the radio this evening brought home (finally - duh!) what is wrong with the expression "Global warming". It'd been at the back of my mind all along, but it finally crystallized - putting heat into a system does NOT necessarily mean that the temperature is going to increase.

Consider ye a bucket of ice, at just below freezing point. Add heat - what happens? Yes! the ice melts. Does it get significantly "warmer"? No! The energy input is changing the phase - anyone who's not familiar with this should check out "latent heat". Then look at Arctic ice cover.

Consider other possible things this additional energy could do - make bigger storms, maybe? They take quite a lot of energy - n'est pas?

Try "climate change".

Where does the energy come from to make new ice?

From water cooling down of course!

Not sure whether you said that with your tongue in your cheek.

If you did, well said. If not (and for anyone else wondering) - please check out the "latent heat" link in the OP, and try to understand it.

The climate isn't doing anything it hasn't done in the last million years, or so. Neither is the earth.

Seems to me that the press has named this natural cycle to suit itself and we have fallen for it.

It's global warming now, in 10,000 years it'll be a global chilling.

Happy holidays.

So your saying we're not feeling the effects of "global warming" because the ice caps are melting? And what happens when the're gone?

According to tcmtech more ice will be made by the "water cooling down, of course".

If you have some other method of making natural ice by adding energy to water I sure would like to know!

Its been a while but I do recall that ice comes from water loosing its thermal energy not gaining energy.

i think the energy is moving "from" the water. the energy "heat" is removed by the condensor.

Well, we are feeling the effects - but not necessarily in increasing temperature.

More extreme weather - stirred up by more energy getting in and not getting out again (balance is changing).

"And what happens when they're gone?" - then we're really f*cked.

Climate change is the new buzzword.

My other comment is: Man they ripped that thread from the front page fast!!!

The newest and bestest buzzword(s) is "Catastrophic Climate Change"

The best we can do is look to the past to see what has happened to this planet we all live on and make a determination given some assumption's to what may lay ahead. None of us were here those thousands of years ago to see really what happen to cause the warming cycles, we can only summarize. Do I think were headed to a warming cycle, yes. Do I think we may have caused some of it, yes. How much has been caused by man is yet to be determined. But, do we wait to make changes until we figure this all out, no. By then it maybe too late!

ok, here's the skinny...I recently attended a lecture by a Professor from U of Florida who studies pollen counts from deep core drill samples from all over the world, specializing in ice age pollen counts.

He says the world average atmospheric temperature has been extrapolated out to about 50 million years ago and the CO2 atmospheric content is directly related to the temp and vice versa.

He showed a chart that basically looked like a heart beat monitor read-out with the high CO2 spikes occuring immediately before the onset of an ice age.

We are currently at about double+ the highest found CO2 percentage.

What has happened during the last 50 million years is that when the CO2 spikes at the high point immediately preceeding an ice age, the average atmospheric temp drops to a low.

What is interesting is that the two measurements, CO2 and average atmospheric temp are DIRECTLY related.

What is going to happen is at a certain point in this century or the next we will be thrown into the beginning of the next Ice Age, the depth of which the Earth has never seen before.

It will be preceeded by a complete clouding over of the entire atmosphere because hot air holds more moisture. The clouds will block out the sun entirely from the surface of the earth except possibly around the equatorial region up to about the middle of Florida.

That's if Man survives the end of the sea ice circa 2040

This is certainly an interesting point. I've heard of this study, can you provide a link?

My point though, has any archeologist, amateur or professiona,l found evidence of the coal fired power plants, or what type of autos and airplanes were used by the locals to cause this CO2 spike?

As for clouds blocking the sun, I understood that water vapor is a more powerful greenhouse gas than CO2
