Medieval Warm Period (Global) -- Summary (30 October 2014)
Prior to the latter part of the last century, the Medieval Warm Period was universally regarded as just that: a several-century period of warmth during medieval times when the earth was somewhat warmer than it was in the late 1990s. It was also widely acknowledged that the MWP had been preceded by the Dark Ages Cold Period and followed by the Little Ice Age. But even before the new millennium arrived, climate alarmists were attempting to alter climatic history by claiming that the MWP was neither all that warm nor global in scope, in an attempt to portray earth's then-current warmth as being unprecedented over the past one to two thousand years, due to the growing greenhouse effect of ever-increasing anthropogenic CO2 "pollution" of the atmosphere. However, the archives of climate science tell a very different story...

Long-Term CO2 Enrichment Studies (Woody Plants - Sour Orange Trees) -- Summary (30 October 2014)
How long does it take a sour orange tree seedling to achieve a long-term equilibrium rate of growth enhancement in response to a given degree of atmospheric CO2 enrichment? An experiment conducted in Phoenix, Arizona, USA provides the answer for a 300-ppm (about 75%) increase above the urban background value of approximately 400 ppm at the site of the study....

Two Thousand Years of Cyclical Drought in New Mexico, USA (24 October 2014)
Solar variations appear to be the primary cause of periods of drought in northern New Mexico over the past two millennia. Inferring they are caused by anything else, including CO2-induced global warming, is a far-fetched stretch...

Why 2014 Won’t Be the Warmest Year on Record (21 October 2014)
Much is being made of the “global” surface thermometer data, which three-quarters the way through 2014 is now suggesting the global average this year will be the warmest in the modern instrumental record. Dr. Roy Spencer explains why he feels this is wrong...
