Global Forest Change 2000 – 2012 Classification of Landsat from two different years http://earthenginepartners.appspot.com/science-2013-global-forest

Global warming

2010 tied with 2005 as the warmest year since global records began in 1880

Global Change monitoring Minimum arctic ice cover Sept 2011 (yellow line = median 1980-2000) Remotely sensed imagery is suitable for monitoring events and changes, with regular orbits

ice predicted to disappear 2030 Kilimanjaro: 1993 and 2000: ice predicted to disappear 2030 Causes ? Global warming b. Lower precipitation c. Intensified land use

TERRA satellite 1999 Includes two sensors: MODIS and ASTER MODIS- bands and applications (250 / 500 / 1000m) http://modis.gsfc.nasa.gov/about/specifications.php MODIS- sensing for global change research: http://glcf.umiacs.umd.edu/library/pdf/ieeetgrs36_p1228.pdf Sample images: http://modis.gsfc.nasa.gov/gallery/showall.php

Percent change within an 8 km grid cell based on the MODIS forest disturbance change product (2001 vs. 2006). It reveals the nature and distribution of change in Canada with large fires in the north and smaller, but spatially more extensive changes to the south. The impact of the mountain pine beetle outbreak in central British Columbia is clear. http://www.nrcan.gc.ca/earth-sciences/geography-boundary/remote-sensing/optical/2208
