Generally the approximate accepted dates of the Little Ice Age start around 1500 and extend to 1850. The actual time of start may be earlier as records indicate that north Atlantic and Artic pack ice began to grow about 1250; in 1350, warm summers stopped being able to be counted on regularly in Europe; 1550 was the noted time of glacial expansion worldwide which greatly expanded glacier size to the levels that they were at the turn of the last century and from which they are retreating today. The glacier advance in Europe during those 500 years swallowed farms and crushed established villages. Crops failed. Marie Antoinette got bad press for suggesting that the populace contain themselves with cheaper, lower protein cake flour.
We began our recovery from that cooler period in 1850. Our records of the actual real temperatures taken by a live person only go back 110 years. Records show that sea levels have been rising 7″ a century since that time as the ice accumulation from the Little Ice Age melted back towards normal. Mr. Gore skipped over this. Glacier shortening also began at about this time, well before the SUV and well before 84% of all of the hydrocarbon burning that has ever been done by man. No mention again. Probably just a coincidence.
