Poll results:  How British people feel about climate change.  It appears that stormy weather has more effect on public opinion than anything else, which is not surprising.
Now see what Robert Fanney has uncovered relative to new El Nino developments, recent storm track amplification now reaching all the way into the North Atlantic, and the enhanced prospect of still more wild storms that are not designed to calm the nerves of Brits, or anyone else for that matter.

A new report from the NREL (National Renewable Energy Lab) analyzing the potential for wind energy in the US.  “With little fanfare, NREL released updated data showing that, with current technology, wind turbines could generate more than enough energy at 55% CF to power the entire US.”  And that turns out to be a conservative view!  This report has revolutionary implications.
