This is what it says on the back cover of my copy of the dvd, "Stopping the Coming Ice Age" from 1988 -- endorsed by science (Buckminster Fuller), Hollywood (Dennis Weaver) and the music industry (Sting).
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.
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!
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."

Unfortunately, the global Warming industry frequently has no science to present either, and it is made up on the spot. People talk about vested interests in the sceptics' lobby, but what about vested interests in pro GW academia, who gain the sponsorship of control freak governments as long as they skew everthing in favour of GW ?
If the GW lobby did not act as if they had something to hide, if they did not continuously maniulate date to their own ends, thinking people could think better of them.
If we didn't hear the repeated lie that "all scientists agree...."; unfortunately, this particular lie seems to be based on the premise that you have to believe in GW to be a scientist, and believing in GW makes you one. Their Nazi-like zeal works against them, and there are some pretty rubbish scientists put forward to make their case.
I am making no comment as to whether GW, man-made or otherwise- is happening. Subjectively, winters seem warmer nowadays, but memories can befuddle us. The data is far less definitive than many would have us believe.
Why does the GW lobby feel the need to act in the way it does ? Why does it so frequently hide evidence and present skewed and incomplete evidence ?
"Hello kettle, this is the pot. By the way, did you know you're black ?".
The sceptics have no science to present. They certainly don't put it into scientific or engineering magazines. This article proves that. Just another Fox News, Rush Limbaugh, Bill O'Reilly appeal to the ignorant masses with high sounding titles to their name.
Rutan is good at designing radical oneoff aircraft - provided you don't want to go into production. His word against hundreds of people taking real measurements - no. And then there are all those other emeritus professors (who regularly pop up with all sorts of crazy theories)
Group think in the US appears to be based on a theory of American exceptionalism and that ideas from elsewhere are "socialism". American news doesn't show half of what goes on around the planet - you have to watch AL Jazeera and the other foreign news programs for that.
Fiddling while Rome burns -- as yet another train load of carbon rolls down the track to be combined with more than it's own weight in oxygen we'd like to breath to muck up the atmosphere.
Do you seriously believe that you can keep on chucking those billions of tons of carbon in to the environment with no effect?
Consider an analogy. Some Civil Engineers assess an old bridge and conclude that it has weakened and may be unsafe. We should reduce the loads we put onto and work towards building a new bridge. Then a group of not very bright people in your town start predicting how the bridge could collapse at any moment, the town will be isolated and we will all starve! From this should you conclude that the bridge is perfectly OK just because the town panic-merchants are in a flap? Or should you go ask the engineers?
If you want to form an opinion about AGW, surely the correct approach is to look into the science. Surely this sort of approach is what we do all through life isn't it? Judge the Message, not the Messenger?
Next, who is saying you are bad. Aren't you being just a little over-sensitive. Or reading something into this that isn't there. What is being said is simple. The bridge is weak, we need to take the load off it and then build a new one. No judgements of anyone there, just a description of a necessary couurse of action.
As to a few tenths of a percent change in Solar output. Solar intensity at the edge of the Earths atmosphere is around 1364 Watts/M^2. Allow for the fact that the Earth is a sphere but the frontal area it presents to the Sun is a circle and we have to divide by 4. So average solar intensity over the Entire Earth is 341 W/M^2. 1 tenth of one percent of this is 0.341 W/M^2. In contrast, each doubling of CO2 in the atmosphere produces a radiative imbalance of 3.7 W/M^2, for the effects of CO2 alone. Over the course of a Sunspot cycle, the sun's output varies by 1 or 2 tenths of a percent So your 'few' tenths (depending on how you define few) will have less impact than the amount of CO2 we have added already
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
