There remains many misconceptions regarding the subject of the climate change that the Earth has experienced over the past 50 to 100 years.
One of the most prevalent falsehoods is the attempt to link individual weather events to climate.
Droughts, snowstorms, heat waves, flooding and other events have all been associated with perceived shifts in climate.
Though there may be a tendency for slightly greater and somewhat more frequent extremes — this because of more energy in the climate system in times of relative warmth — the link remains far too tenuous to conclude for certain.
Secondly, some changes that continue to take place, such as mountain glaciers and arctic sea ice extent, are in part responding to longer term rather than very recent climate changes.
Finally, I believe that many scientists hold the view that other factors, not man, have been and continue to be the primary reason for climate change.
