The world’s greatest climate scientists tell us that Arctic winter warmth is due to trapped heat from CO2, so the the persistent anomalous cold which the Arctic is now seeing can mean only one of two things.
- CO2 levels are way down
- Many climate scientists are idiots
Down Under

nice they have a webcam
I’m inclined to vote twice for No. 2.
CO2 levels are down???? OMG what are the trees going to eat? It’s a frickin’ calamity! Fire up your SUV pleeeeeeeeze!
#2. Idiots is a compliment. I would not rate them that high.
1. No.
2. Yes
Simple.
err. C02 doesnt trap heat. More C02 raises the altitude of the ERL.
Don’t rely on the popularized explanations of the green house effect.
When you raise the ERL the earth cools less rapidly. Its not really global warming, its
reduced cooling. Of course, the effect is small takes decades to become apparent.
In the mean time temperatures will go up and down, but over the long term the effect
from raising the ERL will dominate natural variability, making the highs higher and the lows less low.

The particle soup from 8km up to the heavy side, as you well know is not loosely defined, it is undefined.
The C02 signal within our troposphere is so far in the noise that it is irrelevant as it pertains to what we have and what we are able to measure.
Do you have a grip on argon from 4km to 16km?
Do you understand what happens from the heavy side on down to the surface when our planets magnetic field is compressed by 1% – 5% for a 5-25 hour period?
Do you understand the mechanics involved with varying ERL and the opacity apparent to (incoming & outgoing) spectral bands and the reconfiguration of matter contained within those bands, at variable heights and pressures?

“Greenhouse gases absorb and re-radiate much of the infrared radiation released by the Earth’s surface. (I’d interpret that as CO2 trapping heat)
The main greenhouse gases are water vapour, CO2, methane, nitrous oxide, ozone and the synthetic greenhouse gases, largely chlorofluorocarbons (CFCs).
Apart from the synthetics, all of these gases occur naturally.
There is far more water vapour in the atmosphere than any other greenhouse gas. By mass, it accounts for approximately 0.3 per cent of the atmosphere compared to about 0.06 ( ** it’s 390 ppm?) per cent for CO2.
Human activity does not directly affect the amount of atmospheric water vapour.
However, as the atmosphere warms, it can hold more water vapour.”
So water vapour contributes around 90% to the natural greenhouse effect. I read elsewhere it may be more. And thank goodness else we’d be living on a snowball.
Always good to see the times you make sense, Steve. I mean that in a good way.
CO2 increases the amount of downwelling LWR. That increases the temperature at the surface. Unlike the amateurs here, I actually work with radiative transfer models.
RE: Steven – “Unlike the amateurs here, I actually work with radiative transfer models.”
Your statement assumes facts not in evidence. What an un-Goddard statement.
Hmmm…
The comment was directed at Mosher.
My bad. ChE has been good to me, and they pay me to play.
Since global temperatures are now well below what was forecasted based on the IPCC “commitment” scenario, which assumes ZERO growth in greenhouse gasses since 2000, and since the models MUST be correct, the only other conclusion is that greenhouse gas levels haven’t increased since 2000, despite what the official figures suggest.
There is a third choice.
3. The world’s greatest climate scientists are frauds.
