After analyzing 45 studies from eight countries, Lixin Wang, assistant professor of earth sciences in the School of Science at Indiana University-Purdue University Indianapolis, and a Ph.D. student in Wang’s group, Xuefei Lu, concluded the greening likely stems from the impact of rising levels of atmospheric carbon dioxide on plant water savings and consequent increases in available soil water.
“ We know from satellite observations that vegetation is greener than it was in the past, ” Wang said. “ We now understand why that’s occurring,
but we don’t necessarily know if that’s a good thing or not
. ”
Of course, the ” agenda ” dictates that the usual disclaimer be appended to any summary, thus ensuring continued publishing, grant funding and appeasement of those ” settled ” scientists.
