I think about the effects of global warming all of the time especially since I live on a barrier island- I can see the beach being eroded. I know some is natural, barrier islands are constantly shifting, but the rate seems a bit fast- more than several feet are missing every year. I keep telling my husband that we should move to the mountains near a large water source- like a lake or spring. Of course he thinks I’m crazy and says that if it ever gets that bad, it would be horrible anywhere. Then I think that maybe Florida wouldn’t be such a bad place to be if the Gulf Stream is stopped by the glaciers & poles melting, and we go into some sort of ice age. We’ll be in one of the warmer spots! Did anyone else watch the PBS movie on the glaciers melting?
Hi M.J.,
ReplyDeleteInteresting perspective from you and living on a barrier island. I agree with your husband; it WOULD be horrible anywhere. I wish I knew about the PBS special, that would have been an awesome and timely show to catch. It also would have been a welcome and informative addition to our courses required viewing.
Hi,
ReplyDeleteDid you check Dave's blog? Looks like Florida may not be the best plan... :)
Do you think that the experiment from class is a more accurate representation of glaciers (ice on land) or icebergs (ice in water)? Amy
I was shocked- most of my seventh graders didn't get that sea levels wouldn't rise w/ sea ice melting. I had them write a hypothesis while I did the two mini experiments. They all got the sea levels will rise w/ the glaciers melting. We then got into discussions about salinity levels, what drives the currents, and what could happen if the currents are stopped- they got it! But I had to tell them everything- they have no higher level thinking skills and they are clueless about what is going on out there.
ReplyDeleteHi M.J.,
ReplyDeleteI agree that all of these severe events could happen with global warming. However, I believe that they are all absolute worst case scenarios. I also don't believe this process is going to happen quickly as evident by similar cycles in earth's history these changes are usually gradual.
