John Nelson has created a serial of maps to demo how the bounding main H2O ice extent inwards the Arctic too Antarctic changes over the shape of the year. He has besides mapped out how these bounding main H2O ice extents bring changed over the final xl years.
Historic Sea Ice Events starts amongst a fantastic animated map which shows the freezing too thawing of the H2O at the poles over 12 months. This animation provides a neat overview of the seasonal changes at the poles. Historic Sea Ice Extents besides includes a serial of static maps to visualize the historical records of bounding main H2O ice extent at both poles for every calendar month over the final xl years. On these maps the color of the bounding main H2O ice extent changes past times year. The xanthous lines on these maps demo the bounding main H2O ice extent inwards the about recent years, spell majestic lines demo the to a greater extent than historic records of bounding main H2O ice levels.
These maps clearly discover that the levels of bounding main H2O ice at both poles has been dramatically decreasing inwards recent years every bit a final result of global heating.
John Nelson's maps role information from the National Snow too Ice Data Center. The Center has created its ain serial of interactive maps which visualize Satellite Observations of Arctic Change. These maps let yous to run into how bounding main ice, snowfall comprehend too frozen lay down bring all been shrinking during the 21st Century. Other maps plot air temperature changes inwards the Arctic too the changes to Arctic vegetation.
Global warming is causing observable changes to ecological systems inwards the Arctic. Air temperatures inwards the Arctic are ascent too bounding main H2O ice extent is declining. Even Arctic vegetation is changing amongst tundra beingness replaced past times shrubs. Each of the NSIDC interactive maps uses NASA satellite information too question to plot changes to the Arctic from 1979 to 2015. The maps let yous to discover the information for each twelvemonth inwards this menstruum to discover how global heating has effected the ecological systems of the Arctic.
