Global Cooling And The Great Mandrake :: The Market Oracle

Since 1800 using the best-highest claims of the IPCC, world average temperatures have risen by at most 1 degC. During the Warm Period before year 1300, in some high latitude regions, temperatures were probably at least 5 degC higher than afterwards, during the Little ice Age, and 4 degC higher than today. The recovery since the Little Ice Age would in theory have a long way to go – assuming it can go that far. Assuming it can't, and the Earth's climate clock may not allow the time, temperature falls of at least 1.5 degC are logical and totally possible. Just as important, the cooling can be rapid and will be accompanied by much wetter, unpredictable and “unseasonable” weather.

This is the global cooling fear.
