Predictive Skill: Guess How Many Climate Models Passed the El Niņo Test?: In a study of the ability of climate models to predict the occurrence and nature of the 1997-98 El Niņo event, it is demonstrated, in the words of the authors, that "there were no models that provided both useful and skillful forecasts for the entirety of the 1997-98 El Niņo."  It is also stated that this failure of the models has not only been neglected by certain people who should know better, but that just the opposite has been claimed, i.e., that the models performed admirably in predicting El Niņo characteristics, and that this false claim has been used to shore up climate model predictions of CO2-induced global warming.

CO2 and Sea Level: Who Leads Who?: Evidence continues to accumulate - if you think like a climate alarmist - that sea level rise causes an increase in atmospheric CO2 concentration.

Drought in African Sahel Not of Anthropogenic Origin: A climate reconstruction from a site in the African Sahel indicates that the megadrought experienced there since the late 1960s is not unique, having been preceded by several similar climatic excursions over the prior 1500 years.

Six Thousand Heat Flow Measurements Can't Be Wrong: An analysis of over 6,000 sets of terrestrial heat flow measurements reveals the existence of a warmer-than-present Medieval Warm Period and a colder-than-present Little Ice Age in a global climate history derived from worldwide observations.

Effects of Elevated CO2 on Wheat: Elevated CO2 increased canopy quantum yield, net photosynthetic rates, and seed yield in hydroponically-grown wheat.

Cell Division in Wheat is Affected by Elevated CO2: Elevated CO2 increased rates of leaf cell division and elongation in two varieties of wheat within one week of sowing.  In addition, atmospheric CO2 enrichment increased leaf areas and total plant dry weights.
