We have had some extreme conditions the last few years – of cold, heat, snow and rain. Detailed summaries on the cold last winter can be found here and on the hot summer here. Both were memorable seasons indeed. Though the second author did an excellent job detailing the summer records and did mention the amplified and frozen jet stream, he went on to say man made global warming contributed to it.
Whereas the media and alarmists like to portray extremes (Holdren has called it “Climate Disruption”) as the result of or greatly amplified by man made greenhouse gases, natural factors can be shown as the cause. Too many scientists and media ‘enviro’ bloggers have stated “it must be man-made – what else could it be?”
