Warming and cooling trends... Nothing really new.

Sierra club was pitching Global cooling...
My snowboard had a sticker on it back in the late 80s... it said 3rd Ice age, bring it on.

25 years (approximatly) ago the Farmers Alminac predicted a warming trend and drout conditions that was supposed to extend out... about 25 years...

Shortly after this the Sierra club changed its pitch from global cooling...
to global warming...

Over the past 25 years... things have been changing.
Climates have been drier and warmer.

Cities have sold off thier unused snow plows and de-ice equitment.

Recenly we have had more snow more rainfall and returning to a climate similar to before the 25 year back conditions.

People are refering to Old timee winters now with snow levels not seen in over... 25 years.

Recall a couple years back... Al Gore had a number of his gobal warming conferences canceled due to SNOW.

Cities and having problems clearing roads of snow and ice... they don't have the equipment anymore.

Someone I know who is connected to the Sierra club said they are talking about changing back to... you guessed it... Global cooling.

Ok... enough of that soap box... Seriously though.



Lets look at TREES.... find recent cut older large trees... study the growth rings.
You will see the history of the tree, slow growth years, rapid growth years, forest fires, etc. Its always changing.

If the wet and cooler climates come back in the next few years, so will the new growth levels.

In this image you can see the 1690 time period had 7-10 years of very slow growth (tight rings) even in trees that had been having very rapid growth (loose rings) before and after that time period.
