Too many home truths JV...............???

By the looks of it only the ones that suit your purpose.

To be informed you must listen to both sides of the argument otherwise how can you come to a logical conclusion.................

I read the science.

Radiative forcings are causing the global warming that is being observed. We can see the forcings using spectrometry both terrestrial and satellite.

No other explanation has been advanced that explains the observed warming.

Not the sun, it has been relatively quiet for 50 years. The warming has happened while the sun has emitted less than normal radiation. That is something to think about!

No axial tilt or orbital perturbation has occurred.

It is not a matter of looking at “both sides” it is a matter of looking at evidence and on that basis the AGW theory is doing well. Plenty of scientists looking to disprove it, no real luck with that so far.

Booby thinks he (Dubyne that is) has put forward a theory of “cooling” but since the globe is warming that is nonsense. Dubyne bolsters his bullshit theory by lying about, exaggerating and cherrypicking cold. He has LIED about “record cold” and “record snow” “destroying crops” in Europe this month. I easily disproved this BS claim by looking at weather records and ag. sites.

At a time the worlds granaries were bulging at the seams Dubyne was lying about food shortages. A VERY warm winter (70°F) in Chicago and much of the midwest (and relevant parts of Canada,) usually deep in snow, no snow and spring temperatures midwinter. England—very mild winter.

Interesting thing is: I was alerted to these warm winter temps by comments to the Dubyne videos! Dubyne never, ever mentions warmer than usual temperatures, just lies about cold. Hmmm, the Australian Alps got a dusting of summer snow, not that unusual, and Dubyne reported that as “Tasmania, Victoria and New South Wales “blanketed by snow.” Wild exaggeration.

So much for Dubyne and cooling.

Attempts to show it is the sun doing the warming don’t get far, have to build in all sorts of things like a delay in the effect of solar maxima etc etc, supply of heat from oceans etc etc. Its very complication shows it is a dubious theory—and does not account for the spectrometry data. There really is no explanation by looking at the sun alone.

If you accept there is warming then I can’t see how you can reject AGW.

What is the frequency band of the IR emitted by the sun compared to the frequency band of the IR emitted by the Earth? The IR from the earth is black body radiation, that from the sun isn’t, obviously.

What does this have to do with the IR spectrum observed by satellites?

You mean infrared is not necessarily infrared?

You know the earth is not a black body; don't you?

Jovial Monk wrote on Apr 30^th, 2017 at 3:21pm:



Very good. Now the sun emits white light. What part of spectrum do you think the suns emission of white light differs?

Because it doesn't accord with your beliefs?

"Is earth a perfect black body?"
"No basically a Perfect Black Body is the Body which radiates the amount of radiation which is absorbed.

So Earth doesn't emitt that much amount of radiation absorbed by it so it can't be classified as perfect Black Body."

https://www.quora.com/Is-earth-a-perfect-black-body

It is more a grey body

"Most of the Sun's radiation is blackbody radiation radiated from the Sun's surface, or photosphere, whose temperature is about 5700 K. The Earth's surface is warmed by absorbing this light. At the same time it is absorbing energy, the Earth's surface is emitting its own blackbody radiation. At night, when the surface is no longer being illuminated by the Sun, it is still radiating its own blackbody radiation, the Earth's surface to cool. "

So the earth re-radiates some of its absorbed radiation.

So answer the rest.
