Why Cow-Driven Global Warming Is A Load Of Bull


All animals breathe in air and then breathe it out again.  This astounding fact, seemingly new to some web users, has nothing whatsoever to do with global warming.

Some people are still seemingly astonished to find that cows breathe out air deficient in oxygen and with a surfeit of CO2.  They eagerly report this brand new finding to a breathless crowd of eager supporters of any 'proof' that humans are not responsible for the inexorable rise in global CO2.

Is there some way we can teach our children that there is no such thing as a free lunch?  Perhaps then they will not grow up to think that problems can always be solved - if only we throw enough crazy unscientific ideas at them.


The laws of thermodynamics dictate a simple policy of universal application.  It is one that policy makers must be forced to understand: mother nature will not permit us to reverse a fossil fuel energy production process without using more energy than the process has itself released.


One of the most ludicrous ideas I have ever read about, purportedly coming from scientists, is that we can somehow sequester carbon.  Let me give my reasons.

The sliding rocks are few in number and are found mainly in the southeast.

NASA IceBridge Mission Prepares for Study of Arctic Glaciers


In a world where the blogosphere is filled with politically motivated versions of what is 'really' happening to the cryosphere it is good to know that real scientists are taking real risks to get real data.  I take my hat off to them.

Baird : The Wonder Of Television

The following article was scanned by me from
"The Wonder Encyclopedia For Children"
Odhams, 1933.

Apart from minor adjustments to layout and removal of page references it is verbatim.
I present it here as a view from the past, when television was a brand new scientific achievement being presented as a new wonder to children and using the latest photographic illustration techniques. 

John Logie Baird describes broadcast television in his own words.
