What are the signs that climate change is happening?

    I think the most apparent are melting glaciers and rising sea levels, these signs outmatch contesting view points of possible weather conditions.

    Antarctica actually ISN’T warming, it’s temperature has been consistent for the past 50 years, and some areas are actually getting colder. Similarly, yes the Arctic is melting in the summer, but it always refreezes every winter, that doesn’t show any signs of changing. The Arctic is frozen out of sea water, and thaws back into it, it has little effect on overall ocean height. On the other hand, if Greenland melted the oceans would rise by about 20ft.

    Real effects of climate change can be seen along California’s coast, in the form of coastal cooling (http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2009/07/06/DDJT187GK9.DTL). This same coastal cooling effect can be observed world wide in regions with the appropriate factors present.

    There are other things that could be attributed to climate change, but there is little evidence to back up such claims. Examples of such unsubstantiated claims are that climate change caused Hurricane Katrina and other storms to be stronger. In fact, there is some evidence that climate change has no effect on hurricane strength, and the power of such storms is due to natural decadal oscillations.

    In addition, we can see evidence of global warming in the increased intensity of hurricanes.  In the last few years, while numbers have not significantly increased, we have seen a greater number of more powerful hurricanes in the Atlantic.
