I write to concur with conclusions in Dr S Fred Singer’s recent essay: “The Climate Sensitivity Controversy”, by S. Fred Singer, American Thinker, October 15, 2014. And to solve the puzzles he posed. 
In particular he concludes “climate sensitivity, CS, is close to zero”. This means any effect of CO2 on Earth’s temperature and climate is vanishingly small, hence unimportant. Singer leaves his warmist camp and joins the denier camp of skeptics.
I met Singer at his University of Houston lecture hosted by Prof Larry Bell on February 6, 2012 and his several talks at the latest Heartland Institute ICCC, Las Vegas, July 7-9, 2014. He has played an important role in disputing alarmist global warming claims for decades. He has received many awards.
Singer reveals he assumes CO2 warms Earth because it is called a greenhouse gas, which does not make it so. It is also green plant food, which does chemically make it a coolant. Great confusion arises when a radiating gas, which cools the atmosphere, is incorrectly labeled a greenhouse gas and then warming is arbitrarily assigned to it, by virtue of the nomenclature change.
I discovered in 2012 introducing radiating gases like H2O and CO2 to the atmosphere actually cools the Earth slightly and had useful direct email exchanges with Singer on the matter. Naturally I am pleased he has reached a similar conclusion, perhaps by another way.


Mawson Station, the longest continuously operated outpost in Antarctica, has relied on access to a nearby bay, which is increasingly becoming more complicated by sea ice blocking the way.


The huge amount of plastic refuse in the oceans has been bothering many people for a long time already. The 19-year old Delft inventor Boyan Slat (pictured) thinks he has found the solution.
