A paper titled ‘Global Warming: A Geological Perspective,’ published in Environmental Geosciences
The paper notes that if 'the temp increase during past 130 years reflects recovery from Little Ice Age, it is not unreasonable to expect the temps to rise another 2 to 2.5 degrees C. to a level comparable to that ofMedieval Warm Period about 800 years ago' & 'Climatic changes measured during last 100 years are not unique or even unusual when compared with the frequency, rate, & magnitude of changes that have taken place since the beginning of Holocene Epoch'
‘Recent fluctuations in temperature, both upward and downward, are well within the limits observed in nature prior to human influence’
