Watashi,

You did "this"? Your compalint is that they present no data? You believe?

Have you ever tried to look anything up? Have you ever went to your local library and delved into the scientific journals kept there? Have you ever contacted a researcher for their source data? If you're dissatisfied with their data, have you ever tried to perform your own research?

I have to thank you for presenting a great example of the average denier. I don't know where you get your information but science is all about participating, and it is obvious that you have no such inclination. If you did, you would have done something more than listening to right-wing talking heads and reading right-wing blogs.

Stop being lazy and do some work. You claim to be an engineer yet have chosen to be spoon-fed denier talking points and have chosen to not do your own work, including understanding how climatologists have looked at the implications of solar activity on climate. So, how can you engage in a meanful discussion?

Sorry - I didn't fully address your point.

What I am saying, is that the sun is the primary heat source for our solar system and planet. There is evidence from other planets in our solar system that the earth's warming/cooling trends are not unique. The arbitrary decision to not consider the sun to a greater degree appears to be a suspect choice of "climatologists".

Indeed all the forcings are taken into account and the solar component, which is insignificant anyway, has been diminishing for some time. 



 

However, less well publicised are the indirect and direct influence of aerosols mainly from poorly regulated coal burning sources which reflects sunlight and cancels a lot of the warming out. Reduce this to improve air quality in China for example, and the forcing gets even higher! This is our dilemma.

I did about 10 years ago and the temp data correlated nicely with the measured solar activity.  This was, of course, from an astronomy perspective with objective data and data collectors at a limited number of sites.

My primary complaint with the whole "consesus" crowd is that they present NO DATA, just their analysis.  I don't take any analysis at face value without the raw data available to back it up.

I also beleieve that their analysis is based on flawed or skewed understanding of basic physics principles.  There is always room for discussion over the applicability of one principle over another, but the AGW crowd demands that we all bow at their alter instead of addressing valid complaints with their methods.

Watashi,

You really need to read the scientific literature. Climatologists take solar radiation into account as it's the reason that the earth is warm enough for life as we know it, with a little internal warmth, like that around deep sea vents, for good measure.

What climatologists discuss with regards to the sun is solar variance correlated with temperature. What is seen when one looks at solar activity is that there is essentially no correlation between the rise seen in earth's termperature and solar activity. In other words, the increase we've seen cannot be explained by the sun.

Again, read what the climatologists have written rather than what the mass media, including right-wing outlets, presents.

Taking the macro thermal model approach, I agree that solar effects are probably the principle source of earth's temperature fluxuations.  Like you, I would like to have your question answered.

I am an EE and thermal is not my thing. It sounds like you have put some thought into this so I would like to run this by you - Considering the "greenhouse" effect: In a closed system where heat is input but not radiated away, wouldn't one expect that average day and night temperatures would begin to converge as the insulating material became more effective?  It seems to me that if CO2 is as effective a GHG as many assert, as the level rises, the earth's average temperature would rise but also begin to normalize to a standard temp.

The sea level is a hard thermometer to ignore, a global metric. As the earth warms, the coast moves inland and landmass above sea level decreases. Given a significant part of the human population lives in coastal areas, it will be an easy sell for them and those impacted by their migration.

As for fossile fuels, I grew up in Oklahoma and there aren't a whole lot of new oil wells being drilled there. Fossile fuels are a finite resource and they are being burned up which drives up costs.

As for our family, we have two Prius to minimize our energy costs as fossile fuel prices rise. The Prius also provide emergency power during severe weather outages. For example, there were a string of tornados last April that sliced up the TVA transmission lines. We had 1 kW of Prius electrical power for over four days for lights, TV, and living.

Fuel efficienct transportation and local power generation are a sensible precaution when heading into high-priced fuel and severe storms. So in 1999, we moved from an area about 50-200 ft above sea level, Washington DC, to an area 600-1,000 ft. . . . Just one less thing to worry about.

fatmanonabicycle,

What global warming industry? Is this like the evolution industry, or the inflation industries?

There is no global warming "industry", only scientists doing their jobs as scientists. Manipulated data? You've got to be kidding. When scientists published papers based on manipulated data, it is eventually uncovered by other scientists. Vested GW interests in acedamia? And what are these? If there is a "vested" interest and the science is good, then there isn't a problem. However, if that interest is wrong, then it will eventually be exposed as fraud, by other scientists.

I'm afraid that rather than science, you are paying all your attention to mass media for your information. But here's what I'd like you to do, post EVIDENCE to support your allegations!

Is this all the skeptics got? Allegations of skewed and incomplete evidence with nothing to back those allegations up! This IS the problem with America and it's alive and well in the engineering community. Anti-intellectualism is the last refuge of true believers.

Published in 1938 by the Engineer G.S. Callendar.  If he had the insight based on the scanty evidence and equipment available then, what must he have thought of all this squabbling now?  He must be turning in his grave!

The artificial production of carbon dioxide and its influence on temperature - Callendar (1938) [FULL TEXT]

Abstract: "By fuel combustion man has added about 150,000 million tons of carbon dioxide to the air during the past half century. The author estimates from the best available data that approximately three quarters of this has remained in the atmosphere. The radiation absorption coefficients of carbon dioxide and water vapour are used to show the effect of carbon dioxide on "sky radiation." From this the increase in mean temperature, due to the artificial production of carbon dioxide, is estimated to be at the rate of 0.003°C. per year at the present time. The temperature observations at 200 meteorological stations are used to show that world temperatures have actually increased at an average rate of 0.005°C. per year during the past half century."

Citation: G. S. Callendar, Quarterly Journal of the Royal Meteorological Society, Volume 64, Issue 275, pages 223–240, April 1938, DOI: 10.1002/qj.49706427503.
