    Probably caused by Fred Flintstone and Barney Rubble. Yabadabadoo!

    Once again, there is no ‘normal’ in climate or weather.

    Here is a good summary by Stine himself

    Current and recent research continues to confirm Stines’s original outline. Of course, the “Little Ice Age” was coined right here in the Sierra Nevada!

    Still waiting for that persistent drought.

    Letters To Nature – Scott Stine – 16 June 1994
    STUDIES from sites around the world1–5 have provided evidence for anomalous climate conditions persisting for several hundred years before about AD 1300. Early workers emphasized the temperature increase that marked this period in the British Isles, coining the terms ‘Mediaeval Warm Epoch’ and ‘Little Climatic Optimum’, but many sites seem to have experienced equally important hydrological changes. Here I present a study of relict tree stumps rooted in present-day lakes, marshes and streams, which suggests that California’s Sierra Nevada experienced extremely severe drought conditions for more than two centuries before ad ~ 1112 and for more than 140 years before ad ~ 1350. During these periods, runoff from the Sierra was significantly lower than during any of the persistent droughts that have occurred in the region over the past 140 years. I also present similar evidence from Patagonia of drought conditions coinciding with at least the first of these dry periods in California. I suggest that the droughts may have been caused by reorientation of the mid-latitude storm tracks, owing to a general contraction of the circumpolar vortices and/or a change in the position of the vortex waves. If this reorientation was caused by mediaeval warming, future natural or anthropogenically induced warming may cause a recurrence of the extreme drought conditions.
