  Mostly YouTube videos on climate change.
  
  
• A summary of the current state of Climate Change by Al Crawford
  This Summary of Climate Change is under development.  When I start work on a section I will provide a link to that section below.  By clicking on  Climate Science home 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 this 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.
  
  
• Information pages on climate science
  These web pages listed each contain information about some topic involving the current state of the science of the climate and of climate change.  They are listed in no particular order for the most part.  All are pages that I find interesting and/or helpful in understanding climate change.  Some of the pages are fairly much from the direct scientific source.  But most are summaries of the science that have links to the sources.  The pages that discuss governmental policies involving global warming likely come from news sources.

• Research Climate Scientists
  A Research Climate Scientist is a person who is currently doing research in climatology.  For purposes of this page the primary evidence that a person is doing current research is that he/she has published peer-review papers on some area related to climate science within the past few years.  Membership in a climate research group would also help but is not a requirement.  It is not the objective of the author to make this a complete list by any means.  But it is a list of researchers who have come to the attention of the author during his study of the climate and of global warming.  The comments about each person are normally from the researcher's own website.  And, normally, a list of his/her publications can be found on that website.

• Artic Sea Ice Extent (Area of ocean with at least 15% sea ice)  Note:  This graph is updated daily by the National Snow and Ice Data Center, as of July 2008.  Therefore, what you see is the Arctic Sea Ice Extent as of the day you are viewing it.

Other daily chart of  sea ice area and extent is found at the Arctic ROOS website and at the IARC-JAXA website are below:

   

  

Arctic Sea Ice Volume:  
The chart on the left gives the current anomaly in Arctic sea ice volume from the long term trend line.  The chart on the right charts the current sea ice volume.

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.

Top 10 Warmest Years (1880–2012) The following table lists the global combined land and ocean annually-averaged temperature rank and anomaly for each of the 10 warmest years on record. Rank 1 = Warmest Period of Record: 1880–2012 Year Anomaly °C Anomaly °F 1 2010 0.66 1.17 2 2005 0.65 1.17 3 1998 0.63 1.13 4 2003 0.62 1.11 5 2002 0.61 1.10 6 (tie)* 2006 0.59 1.07 6 (tie)* 2009 0.59 1.07 6 (tie)* 2007 0.59 1.06 9 2004 0.58 1.04 10 2012 0.57 1.03 *Note: Tie is based on temperature anomaly in °C.

The 1901-2000 average combined land and ocean annual temperature is 13.9°C (56.9°F),
the annually averaged land temperature for the same period is 8.5°C (47.3°F),
and the long-term annually averaged sea surface temperature is 16.1°C (60.9°F).
