Another debunking of two of UNSkeptical UNScience -SS's- so-called "Myths." This time debunking their #45 and #139
|"There's no empirical evidence"||There are multiple lines of direct observations that humans are causing global warming.|
There is empirical evidence that the rising temperatures are being caused by the increased .
There’s no empirical evidence to support AGW.
|"Murry Salby findsrise is natural"||Multiple lines of evidence make it very clear that the rise in atmospheric is due to human emissions.|
Murry Salby finds CO2 rise is natural.
He’s probably right. See items 45, 46, 77.
Salby’s work on isotopes which the alarmists say prove the increase in CO2 is due to humans in fact shows the opposite.
As Jo Nova notes :
Salby points out that while fossil fuels are richer in C12 than the atmosphere, so too is plant life on Earth, and there isn’t a lot of difference (just 2.6%) in the ratios of C13 to C12 in plants versus fossil fuels. (Fossil fuels are, after all, made in theory from plants, so it’s not surprising that it’s hard to tell their “signatures” apart). So if the C13 to C12 ratio is falling (as more C12 rich carbon is put into the air by burning fossil fuels) then we can’t know if it’s due to man-made CO2 or natural CO2 from plants.Salby has been vindicated in a number of ways as shown at item 45.
In addition new satellite data show the developed nations are net absorbers of CO2 which contradicts the alarmist claim and new Swedish research supports Salby.
Salby is a straight shooter. He has been vilified by the alarmists and treated in the usual alarmist/watermelon way at his job at Macquarie University. All because he acted like a true scientist.
