    Critique of Zhao and Running's Technical Response to our Technical Comments
    Example Press Coverage

    The left panel shows the NASA MODIS satellite-measured greenness of vegetation on our planet on a scale to 0 to 1. The tropical forests of South America, Central Africa and Equatorial Asia register the most greenness, while the deserts register the minimum greenness. The right panel shows regions where vegetation greenness increased (in increasing shades of green color) and decreased (in increasing shades of red color) during the 2000-2009 period. Contrary to previously published report (Zhao and Running, Science, Vol. 329, p. 940, 2010) and in their Technical Response to our Comments, this figure clearly shows that over 85% of the vegetated lands South of 70N showed no statistically significant changes during the 2000s.
