UK and U.S. left-wing agenda "scientists," associated with the IPCC fraudulent hockey-stick affair, attempted to dictate to other scientists that the Medieval Warming Period was an isolated phenomenon only experienced by the Europe/North Atlantic region -- most paleo-climate researchers rejected the lame arguments of the IPCC authors and continued to find non-European regions that experienced the Medieval Climate Anomaly (MCA), including Obama's birthplace

Nope, we're not speaking of Obama's first birthplace, the one before he decided to run for U.S. president, although Kenya does have a warm and humid climate.
Instead, the research was done in the Hawaii area, the newer birthplace of Obama after his U.S. Senate election. Specifically, the study was done at the scenic Kealia Pond, Maui.
These scientists wanted to determine what impact the MCA had on the tropical island, where the UN's IPCC scientists had claimed there was no impact. As scientists dedicated to the scientific truth, they ignored the IPCC's dictates (i.e., flimsy reasoning) and pursued their research.
"Based on "high-resolution palynological, charcoal, and sedimentological analysis of a sediment core from Kealia Pond, Maui, coupled with archaeological and historical records,"... Pau et al. developed "a detailed chronology of vegetation and climate change since before human arrival."...Most pertinent was the three researchers' finding that "a shift from dry to wet climate conditions marked the beginning of the Medieval Climate Anomaly (MCA) as evidenced by a precipitation reconstruction based on a pollen abundance index." They note, for example, that over the 2500 years of their record "there have been two major climatic events: first the MCA (AD 800-1300), followed by the Little Ice Age (AD 1400-1850)."...In the case of the early inhabitants of Maui, Pau et al. write that "an increase in forest resources during this wet climate interval coincided with rapid Polynesian population growth," which suggests that the Medieval Warm Period was a time of prosperity for them..."

Regardless of which falsehood of Obama's birthplace one chooses to believe, there is no choice concerning the truth regarding the Medieval Climate Anomaly. Its impact has been substantiated by reams of empirical research and peer reviewed articles. The Medieval Warming Period impact was immense, stretching across the entire world, even touching the tropical islands of Hawaii.
