The 11-year sunspot cycle number 24 has just ended. We are entering sunspot cycle 25. The number of sunspots has been decreasing over the past 3 cycles which has been about 4 decades. See plot below.
Note cycles 20 to 22, with an increase in peak sunspot number, is the same period that global warming has been claimed to be most significant . Then from cycle 22 to cycle 24 we see a decrease, but also there have been reports of global cooling, most significantly in the last decade or so.
Over the summer of 2019/20 we have been repeatedly told that the heatwave has been “unprecedented”. But is that actually true?
This is a map, not created by me, which shows some of the past daily maximum temperatures in Australia. I personally in the summer of 1976/77 experienced 55 degrees C in near Eucla in central southern Australia. But these temperatures highlight the false claims of the global warming alarmists that continually repeat their claim that the earth is warming at an unprecedented rate and that it is caused by human activities, mostly burning fossil fuels.
See the temperature recorded at Bourke NSW in 1909? 51.7 C was the officially recorded temperature. But the Australian Bureau of Meteorology (BOM) has wiped it off the records. In fact, they wiped off all records before 1910. So when they say “since records began” they mean since 1910.
