How much does an air conditioner dehumidify?
Q. Providing an air conditioner is powerful enough to cool a room well and is rated at, say 3 litres an hour of water extraction, how would the relative humidity of the room be affected? If the relative humidity, was %80 before the AC was turned on, what, roughly, would the relative humidity be a few hours after use? I know many factors are involved, not least being the make and model of the AC but I am looking for a very vague idea. Could a reduction of %40 humidity be achieved, or is %5 more likely?

A. There really isn't enough information given to perform a calculation. Getting the Right Size is Essential to Getting the Most from Your New Equipment The following is taken from the EPA "Energy star" site. (Link given below) Some contractors will use rules of thumb to size your air conditioner, but rules of thumb can overestimate the size needed. A good contractor will use a design load calculation to size a central air conditioner to your home. The contractor will need to check the following six factors. How well your house is insulated How well air leaks are sealed How well your ducts are sealed and insulated The size, type and number of windows and the direction they face Shading provided by overhangs and landscaping The size,… [cont.]

Will you measure atmospheric changes during Annular Solar Eclipse on 15 th January, 2010?
Q. It will be visible in Indian ocean & some parts of south India. Partial Eclipse will be visible in large area of the earth. Wherever > 90 % area of solar disc will be covered by the moon's disc, it will be worth watching to observe changes in weather data like reduction in atmospheric temperatures( by abt 4 degree C or less), sunshine intensity( by > 90 %) to be measured by luxmetres, increase of relative humidity & chages in wind speed, wind direction & Radon activity in the air in earthquake & tsunami prone areas. Accoeding to Dr Stewart of England, b coz of reduction of air temperature, infrasonic low frequency inaudible sound waves(frequency < 20 cps) are generated due to compression of air touching the ground, a human being can't… [cont.]

A. Interesting reading. I remember watching a partial solar eclipse, here in Norway, a few years ago. It was in the middle of the summer and what I remember best is that, as you write, the birds stopped singing during the eclipse. They definitively sensed something.

Is the conclusion that GW is real, and mostly caused by us, based on non peer-reviewed science?
Q. The non-peer reviewed references cited on denier websites come from the group working on both actual and potential effects and comprehensive mitigation strategies, Working Group II. It's hardly surprising that they include some non-peer reviewed references among the peer reviewed ones. This is a topic which blends science, economics, and politics. For those still on the global warming denial train, let's see your list of non peer reviewed references for Working Group I, Chapter 2, the part of the report that says global warming is real, and mostly caused by us. I'll quite concede that some of the potential effects and mitigation strategies are speculative, will others concede those two points? To give people a more objective look at… [cont.]

A. There are 759 references in the WG1 Ch2 link you provide. Looking through them, I didn't see one that wasn't a peer-reviewed study. Most were from journals like Nature, Science, Geophysical Research Letters, Tellus (I had to look that one up - it's Swedish), etc. Sure looks like it's very thoroughly peer-reviewed to me.
