I was read the A Meteorological Account of the Weather in Philadelphia and planned do some plots, but Steve bested me. Thanks Stevel
From 1790 to 1804, Philadelphia July temperatures dropped almost eight degrees.
A Meteorological Account of the Weather in Philadelphia
So far this month, Philadelphia temperatures have averaged 79F.
Thirty years from now, alarmists will be saying that 50 years with no warming isn’t long enough.
The Next Grand Minimum 
Russ, And the record breaking lows keep coming as were in summer!! Out of 119 records broken, 117 of them were lows!! Only 2 of them were record high’s. I should point this out to everyone and the link is here http://www.wunderground.com/climate/extremes.asp normally we see record breaking high’s in the summer and record breaking low’s in the winter. With co2 at 400 parts per million in the atmosphere and we are still cooling!! David Archibald is right when he said, ”It’s the sun silly” Anthony
What could really blow the global warming crowds minds is when CO2 starts to fall due to colder oceans. All that cold water will suck CO2 up like a sponge.
What some people seem to forget is that while, yes the solar weather definitely has an impact on Earth weather, it is cyclical. The Dalton and Maunder Minimums are limited time events, roughly 14 to 70 years in duration with effects lasting a little longer. However, the increase in CO2 and climate warming have parallel curves. In addition, once CO2 is in the atmosphere it does not degrade and can only be scrubbed away through plant (land and sea) sequestration.
The coming minimum, if it lasts long enough, will temporarily counter some of the effects of CO2 and provide us a little time to get our carbon fuel addiction under control, i.e. energy conservation and expansion of alternative energy sources.
Minimums are part of the 11 year solar cycle and given enough time, we will find that the Maunder type minimums are cyclic too. However, CO2 pollution above natural fluctuations is man-made and climbing at an alarming rate.
We can’t count on a Maunder Minimum to set the world right and save our bacon.
Doubling CO2 will only increase temperatures by about 1.5 C, while enhancing agriculture production. This CO2 increases could offset the agriculture losses due to shorter growing seasons. What is to worry about? Oh!
