For those who enjoy following every twist and turn in the debate over global warming–its existence and significance–a new study discussed in the UK Telegraph finds in a "review of more than 240 scientific studies…that today's temperatures are neither the warmest over the past millennium, nor are they producing the most extreme weather—in stark contrast to the claims of the environmentalists.
The review, carried out by a team from Harvard University, examined the findings of studies of so-called "temperature proxies" such as tree rings, ice cores and historical accounts which allow scientists to estimate temperatures prevailing at sites around the world.
The findings prove that the world experienced a Medieval Warm Period between the ninth and 14th centuries with global temperatures significantly higher even than today."
