Some global warming facts
Re: When the warming stopped, FP Comment, David Whitehouse, June 23.
It would appear, based on data sets from at least three respected scientific organizations, that global surface temperatures recently remained approximately constant for a dozen years or so. We hear little or nothing from the federal government or various provincial governments about t his result. However, they continue to pledge vast amounts of money to combat global warming when it is not yet clear to what extent human activity actually contributes to climate change.
Could it be that while scientists are expected to present all the evidence concerning a particular question, governments need to present only those data favourable to their political aims?

Liberal governments and socialists tell us we must reduce our use of fossil fuels to reduce the level of carbon dioxide in the atmosphere so as to prevent catastrophic rises in global temperatures. And under UN auspices, climate models were created to demonstrate how increases in CO2 levels would affect global temperatures.
But as CO2 levels have steadily risen over the past 20 years the alarmists’ predictions of the effect on global temperatures have been totally wrong, and in fact as the above article indicates, there has been a 20- year pause in temperature rises when one excludes the naturally occurring El Nino effect.
A rational government that wanted to base climate policy on scientific evidence would thus also pause and reflect before instituting very costly regulations and taxes on fossil fuels. However, a rational government, whose objective is instead to control people’s lives, would disregard the scientific evidence, find excuses for the contradictory evidence, or simply make up fake evidence. Clearly, for Liberal and other socialist leaning governments, the twisted term “policy based evidence making” is quite apt with respect to the climate as well as in many other areas.
