Cold facts?

The Scotsman - - Perspective / Letters To The Editor -

The Scots­man re­ports on so-called man made global warm­ing has been re­ported in the mass me­dia, specif­i­cally Vol­ume 1 of US Govt. Fourth Na­tional Climate As­sess­ment.

It pri­mar­ily blames the amount of CO2 in the at­mos­phere. But stud­ies sug­gest that CO2 lev­els were 10-20 times higher in the past. All that coal, gas, oil, lime­stone and chalk in the ground is there be­cause liv­ing be­ings se­questered CO2 from the at­mos­phere. And yet life on earth wasn’t de­stroyed dur­ing th­ese past pe­ri­ods of high CO2, which is con­trary to the im­pres­sion that you’d get from such re­ports. For ex­am­ple, Steven Hawk­ing re­cently pre­dicted 250-de­gree tem­per­a­tures, wind of 100 me­tres per sec­ond and rain in the form of acid, from a rel­a­tively mod­est rise in CO2. Surely if this were true life in the past would have been de­stroyed?

The warmists want us to be­lieve that CO2 has its hand firmly on the world’s ther­mo­stat. How­ever, a 1999 study led by J Petit at Vos­tok in Antarc­tica sug­gests oth­er­wise. Vos­tok has some of the deep­est ice in the world and Petit’s team drilled down and ob­tained proxy measurements of tem­per­a­tures and lev­els of CO2 and meth­ane go­ing back 420,000 years.

The re­port states that dur­ing the start of ice ages “the CO2 de­crease lags the tem­per­a­ture de­crease by sev­eral thou­sand years”. In other words, the tem­per­a­ture falls hugely while CO2 stays the same, also tem­per­a­ture falls first, then CO2 falls much later.

How can tem­per­a­tures fall when CO2 stays so high? GE­OFF MOORE
