Greenhouse Myth Buster No. 2
Another key indicator of greenhouse warming, a pattern of temperature change “uniquely associated with the enhanced greenhouse effect” according to Dr Braganza, is greater warming in winter compared with summer.
Not in Australia.
This is a graph of summer annual means minus winter annual means for the years 1910 – 2012, straight from BOM’s time series data.
No winter increase over summer in 103 years. This summer- we find out in early March- will have to be less than +0.7 C above average to make the trend ever so slightly negative (to 5 decimal places).
But then how will we get another “Angry Summer”?
