This Climate Science review is under development.  When I start work on a section I will provide a link to that section below.  Following the links below you will be able to access a great deal of information from other sources on Climate Change.  Much of that information will find it into the summary.  The purpose for me in developing this summary is make clear in my own mind what I know (and don't know) about Climate Science and to learn more in the process.

The earth's climate is an extremely complex system.  Science is learning more and more about that system each day and tools are constantly being developed to aid in the increasing body of knowledge of the climate system.  As science changes so will these pages change.

    The following Web sites have more information on the science of climate change:


    Below left is the University of Illinois Cryosphere Today's website graphic of the current sea ice coverage of the Arctic Ocean.  This graphic gives a view of the current ice conditions of the Arctic including the percentage of coverage of each area of the Arctic.  The one on the right is from the Daily Sea Ice Images from the National Snow and Ice Data Center  For a larger view click on the image.

    The NOAA State of the Climate 2009 report is an excellent summary of the many lines of evidence that global warming is happening. Acknowledging the fact that the planet is warming leads to the all important question - what's causing global warming? To answer this, here is a summary of the empirical evidence that answer this question. Many different observations find a distinct human fingerprint on climate change:  See Here

    * CO2 emissions grew 5.9% in 2010 to reach 9.1 GtC (33.5Gt CO2), overcoming a 1.4% decrease in CO2 emissions in 2009 
    * Including land-use change and deforestation, in 2010 emissions reached 10.0 GtC (36.8 Gt CO2)
    * As of 2009 developing countries now emit more than developed countries in terms of consumption, and China now emits more than the US in terms of consumption  See Here
