Still cold…

It has been particularly cold in Adelaide this winter. I like seasons, but it is high time for spring to come now, I reckon.

Despite all the hysterical hype from the climate alarmists, it is quite a bit colder these days that it was during the medieval warm period, which was quite a bit colder than the Roman warm period, which in turn was quite a bit colder than the Minoan warm period. That, at any rate, is the evidence of the Greenland Ice Sheet as reconstructed by Alley (2000) from GISP2 ice core data, shown here in blue:

None of this a surprise; these were periods when civilisation was particularly thriving – we all do better in nice weather.  Interestingly, the red line shows how carbon dioxide levels have been rising over the past 8,000 years and – again despite the ranting of the loons – carbon dioxide is a good thing for plant life. So although we are suffering from colder weather, we are benefiting from more healthy conditions for plant life.

That is a good thing too, I reckon. We all do better if the gardens are thriving.
