To The Horror Of Global Warming Alarmists, Global Cooling Is Here
"Around 1250 A.D., historical records show, ice packs began showing up farther south in the North Atlantic. 
Glaciers also began expanding on Greenland, soon to threaten Norse settlements on the island. 
From 1275 to 1300 A.D., glaciers began expanding more broadly, according to radiocarbon dating of plants killed by the glacier growth. 
The period known today as the Little Ice Age was just starting to poke through.
...Colder winters began regularly freezing rivers and canals in Great Britain, the Netherlands and Northern France, with both the Thames in London and the Seine in Paris frozen solid annually. 
The first River Thames Frost Fair was held in 1607. 
In 1607-1608, early European settlers in North America reported ice persisting on Lake Superior until June.
...The Little Ice Age, following the historically warm temperatures of the Medieval Warm Period, which lasted from about AD 950 to 1250, has been attributed to natural cycles in solar activity, particularly sunspots. 
...The increase in global temperatures since the late 19th century just reflects the end of the Little Ice Age. 
The global temperature trends since then have followed not rising CO2 trends but the ocean temperature cycles of the Pacific Decadal Oscillation (PDO) and the Atlantic Multidecadal Oscillation (AMO). 
Every 20 to 30 years, the much colder water near the bottom of the oceans cycles up to the top, where it has a slight cooling effect on global temperatures until the sun warms that water. 
That warmed water then contributes to slightly warmer global temperatures, until the next churning cycle..."
