From Dr David Evans It has superficial plausibility. Yes, global warming is occurring. Yes, carbon dioxide is a greenhouse gas and levels are rising. And yes, every molecule of carbon dioxide we emit causes some global warming.
Many non-scientists think that proves the case, but it doesn’t. In particular, it doesn’t rule out the possibility that carbon dioxide is merely a minor or insignificant player, and that something else is the main cause of global warming.
Here’s a clue: the world has been in a warming trend since 1680, the depth of the Little Ice Age. It has warmed steadily since then, at half a degree per century. Within the trend there is a pattern of 25 – 30 years of warming followed by 25 – 30 years of mild cooling. We just finished a warming period that started in 1975, so chances are we’ll have mild cooling for the next couple of decades. But there were no SUV’s in 1680. Human emissions of CO2 were miniscule before 1850, nearly all come after WWII, and a quarter since 1998. Yet the warming trend was as strong in the 1700s and 1800s as it was in the 1900s. First, they have a track record of greatly exaggerating temperature increases. The global warming scare was started by James Hansen in his presentation to the US Congress in 1988, and comparing his predictions then to what actually occurred, the actual temperature rises are about a third of what he predicted. Remember, they have been saying the “science is settled” since the early 80’s, and the models now are essentially the same as they were then.
The trick is that they never put any alarmist climate scientist in a position where they have to answer to a knowledgeable critic.
Alarmist climate scientists do make public appearances, but never in a situation where they come under sustained questioning or criticism from anyone who understands models. They have avoided any real debate in public for decades – these alarmists have never been held accountable, they’ve never had to answer to people who knew the problems with their theory. They have never faced an audit, an inquiry, a Royal Commission, or even a hostile interview – yet they get paid megabucks and presume to tell the rest of us how to live our lives. This corruption has to end. We have repeatedly called for a Royal Commission into the science before taking action, but were of course ignored.
Professor Andy Pitman is the leading climate scientist in Australia. Andy has about 20 PhD students working for him, has had millions of dollars of researching funding, and holds lots of prestigious positions in the climate establishment. He recently refused to debate William Kininmonth and me, in the usual dismissive way “I won’t debate people who don’t believe in gravity”. Kininmonth was head of Australia’s National Climate Centre for 12 years, and spent 38 years at the Australian Bureau of Meteorology. These are some of the eco-tards who we have to deals with they have no clue about the real world just how much they can scam to keep the research dollars coming in.
