As a hobby friut tree grower (400 trees) I spend a fair amount of time outside.
Let me say the suns radient heat this summer has been as potent as I can recall.
A bee keeper freind confirms the same as have a few others I have mentioned it to.
Such evidence counts for little but there is no way the said theory of global warming just suddenly pops up on a chart like that.
Is it possible the sun can have a varying temperature or heat which radiates from it?
Surely there is equipnent to measure this?
