This presentation discusses periodic solar-lunar influences on long-range weather dynamics and climate based on key signals such as the 22- and 60-year cycles. The nature of solar-lunar drivers of jet-stream shifts is explained and the basic principles of a unique long-range weather forecasting technique are presented. Verification results for the new technique from the past 4 years are discussed for Europe, Asia and the USA. Implications of the technique for predicting decadal to millennial time-scale climatic changes are analyzed with a specific emphasis on the question: What's coming next — a Global Warming or a Global Cooling?

Piers Corbyn's long-range forecasts have been consistently significantly more accurate than those issued by the UK's Met Office. This fact has made the European News several times in the past 4 years. The most recent example is the record-cold weather and snow blizzards that hit England and Europe in December of 2010, which were forecast by Corbyn more than a month in advance, while the UK Met Office was predicting 'mild' weather for the same period.

Additionally, preliminary results from applying the solar-lunar technique to predict major earthquake and volcanic events around the world are also discussed.
