Climate Changes & the Tropical Species’ danger
Even if the climate changes’ consequences are expected to become more noticeable in the poles, scientists report that it’s possible to also cause a greater threat for the species that live in the tropical zones. Tropical species are used to live under small temperature ranges, thus, according to a published analysis in a weekly edition of Proceedings of the National Academy of Sciences (PNAS), they might not be able to face even variabilities of a few degrees. Until today, the scientists’ priority has been the research of the climate changes’ influence on species in the poles, for instance the polar bear. Those animals though, seem to be used to those changes of temperature, in contrast to those that live in the tropical zones.

“Disconcerting as it may be to true believers in global warming, the average temperature on Earth has remained steady or slowly declined during the past decade, despite the continued increase in the atmospheric concentration of carbon dioxide, and now the global temperature is falling precipitously.” Dr. Phil Chapman wrote in The Australian on April 23. “All those urging action to curb global warming need to take off the blinkers and give some thought to what we should do if we are facing global cooling instead.”
Chapman neither can be caricatured as a greedy oil-company lobbyist nor dismissed as a flat-Earther. He was a Massachusetts Institute of Technology staff physicist, NASA’s first Australian-born astronaut, and Apollo 14’s Mission Scientist.

That link was rather interesting. I couldn’t believe that the issue of global cooling was on the surface of environmental problems.I guess it opens our eyes to the real problem of cyclic variations of the temperature.I believe what needs to be done, is scientists taking into consideration those views of ‘cooling’ and make sure we are prepared for both phenomena depending on the time period in which they will occur.
