Major changes in the earth’s atmospheric weather patterns or climate change, such as global cooling or warming, is actually considered a common occurence. For years scientists have been trying to figure out what keeps glaciers continually growing or shrinking, as well as the development of new species of flora and fauna to the extinction of them. Climate change is a part of the Earth’s history, but the speeding up of such events also seem to be affected by human activity.
Just recently scientists are worried about the effects of such changes on butterfly migration patterns and problematic die offs. According to a new study, by Global Change Biology, data that was collected from two hundred species of butterflies from a Canadian Museum in order to determine various species sensitivity to temperature changes. When comparing this data to the data of 130 years of atmospheric weather tracking information, it was found that the flight seasons of butterflies is being thrown off due to irregular warming and cooling patterns due to recent climate change. This in turn could spell bad news for many species of butterflies, unless some of course develop the ability to habituate and evolve with the recurring changes of weather we are experiencing.
Take a look at the picture I have above. What are these animals and what theories have you heard about that brought them to their demise? These Woolly Mammoths had it made until they started to feel the effects of climate change. While there are many theories out there trying to explain away what really happened to these magnificent creatures, only a few seem to work together more than any other possibilities. From my studies, I have learned that these grand creatures were built to live in extremely harsh conditions, but not so harsh that they could not support their body mass. A terrain of frozen steppe and cool grasslands near glacial sheets is where most Mammoths thrived. When this type of environment started to become more scarce, the mammoths seemed to be unable to acclimate to these climate changes. Another theory is when our ancestors also lived amongst these creatures, we have possibly helped if not hurt the surviving numbers into extinction during the weather flux.
As for the butterfly example, what can be done? Sadly, no one knows for sure, other than when it comes down to the nitty-gritty, we may only see certain butterflies in Zoos in the not so far future, as with other species having similar difficulties. In atmospheric studies, many researchers learn the past, present and future capabilities of what a variety of patterns brings. But I also like to remind others that such studies are not a perfect science either. Climate change has been researched for many years lately, and many scientists have come to terms that our world is in a constant flux of warming and cooling trends that result in our climate change over time. Although, there are obvious concerns of whether such natural patterns are being sped up, or messed up should I say, in some fashion that certain human activities are harming our atmosphere. So yes, Climate Change seems to be a normal scientific event our Earth goes through in so many years with or without humans it seems, but with humans possibly speeding things up, no one know for sure what we are really looking at lately.
