    One engineers perspective on global warming

    A little blown away by the arrogance of that statement. As if someone can't objectively look at the evidence and reach an independent conclusion that also happens to be generally consistent with the scientific consensus?

    One engineers perspective on global warming

    Why did you include a link to the 'hockey stick' when you were referring to a positive feedback that 'will' happen? The hockey stick portrays past temperature change, not what is predicted to occur in the future. Why didn't you link to a model-based temperature projection into the year 2100, of...

    (can of worms alert) Globe hasn't warmed in the last 16 years

    If it only moved heat around laterally across the surface then you wouldn't expect a change in global average tempreature. But since ENSO also affects vertical ocean currents, which can temporarily alter total heat content within that sliver of area called the 'surface' (where global average...

    (can of worms alert) Globe hasn't warmed in the last 16 years

    And I don't see how your observations about a physical glass greenhouse have anything to do with a greenhouse gas...unless you're just confused by the fact that they happen to share a name.

    (can of worms alert) Globe hasn't warmed in the last 16 years

    The guy in the balloon was over 120,000 feet high -- well above the tropopause where temperatures stop falling and begin to start rising as you continue to get higher into the atmosphere. That effect is in no way inconsistent with the greenhouse effect. There is plenty of experimental proof...

    (can of worms alert) Globe hasn't warmed in the last 16 years

    Option 42 there is a group of school children from an ultraadvanced alien race in a faraway solar system that amuse themselves by projecting a hyperconcentrated micrwoave beam onto our planet like a magnifying glass over an ant hill.

    Let's burn more sunshine

    Exactly. For some reason with CFLs, people mysteriously forget that cost usually correlates pretty well to quality. They buy the cheapest brand of CFL they see, then when it doesn't work well criticize the entire technology, instead of just that brand. Pay the extra 50 cents for a quality...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    Usually true. Except, we were talking about government :) They do this anyway as people's use of electricity changes, for varying reasons and frequencies. If they can accept the challenges of uncertain demand, I see no reason they cannot also learn to accept the challenges of uncertain supply...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    30 makes you feel great if they're taken within the right time frame. 1 hour is bad, 10 years is pointless...but 3-4 days, and you've got a nice little weekend. Shouldn't it be the same for energy solutions? Too slow and they don't make a respectable impact, too fast and you waste money trying...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    Efficiency is definitely the best bang for the buck. It's proven, quick, easy, and can result in huge gains. However, it also happens to be very boring. I’m reminded of scenes of people laughing and handing out mock tire pressure gauges amid chants of 'drill baby drill'. Building a giant dam, or...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    Researching better storage methods is a terrific use of money, regardless of its source. But I wouldn't say that expanding production of wind turbines is a "waste". They supplement existing generation facilities, and give private investors more confidence for risking their money on related...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    If the challenge of efficient storage could be worked out, then even an intermitent source could provide 100% of a community's electricity needs.

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    And it *COULD* be fairy dust from Europa or the reflection from a thousand orbiting teapots. To demand that every creative idea be ruled out before an already strongly supported hypothesis be accepted is a fantastically convenient way to delay action until never, because the wonder of human...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    Where did I personally attack you? I said you implied that they were dumber than cows, because you did. You implied scientists were not aware that standing in the open sun in a field felt hotter than standing in a forest. The cows know this, but according to your claim, the scientists do not...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    You’ve changed your argument. Before you were arguing that albedo calculations were wrong because they didn’t take into account photosynthetic effects. Now you are saying they are wrong because they don’t take into account the elevation difference between trees and crops. Except my ballpark...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    Apologies for not having understood your original premise. As I said, I have seen the UHI argument brought up a hundred times. But I have never seen anyone make the claim that you have, of urban albedo affecting the entire global temperature. Well, there are many skeptics who I suspect would...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    So, you are trying to say that waste urban heat extends beyond urban areas to make the entire planet warmer. Fine. However, the entire premise of the urban heat island argument (which you apparently never learned from your fellow “skeptics”) is that urban heat sources make urban temperature...

    Educated Opinions on Climate change - a denouement or a hoax? Part 2.0

    The vast majority turns into heat. My point was that anthropogenic activities in the form of deforestation effect a negative radiative forcing. If you are trying to emphasize that some of the radiative energy gets used for photosynthesis, then the greater efficiency of crop plants compared to...
