一个新的千年暖期可能已经来临

A New Millenary Warm Period May Be Emerged

利用１．５万年来的Δ１４Ｃ记录和２６００年来的太阳黑子周期长度（ＳＣＬ）资料， 发现太阳活动存在时间尺度为２．１～２．８ ｋａ的准周期波动， 它们与全球气候的冷暖波动非常吻合。从最近一次“双千年波”的ＳＣＬ变化规律可知， “千年暖期”开始的标记是持续约３００年的太阳活动特别稳定期（ＳＣＬ在９～１２年之间）。自１９１０年来太阳活动进入特别稳定期（ＳＣＬ在９～１２年之间）， 且至今已维持了９０年。这与“千年冷期”中太阳活动只有短暂的稳定期有质的区别， 它很可能是一个新的“千年暖期”开始的标记。Δ１４Ｃ记录和统计预报结果支持此结论。

A quasi－periodic wave length about 2.1-2.8 ka was found with Δ14C recorder since 15 ka BP and with the sunspot cycle length (SCL) over past 2600 years. They are identical in climate wave of cold and warm over the global. A start marker of millenary warm period is special stability (SCL is in 9~12 years) of solar activity last out 300 years based on SCL′s law of last ‘double－millenary wave’. The stability has been sustained 90 years since 1910 what has qualitative difference with short stability of solar activity in ‘millenary cold period’. So, it may be a start marker of ‘millenary warm period’.
