One of the most important ingredients for plant growth is water. (click here) In many ecosystems, particularly grasslands and cropland, seasonal plant growth occurs in perfect synch with the rainy season. In times of drought, vegetation in these ecosystems grows poorly, if at all. Abundant rain leads to a burst of green. Other ecosystems, such as the boreal forests of northern Russia, Europe, and North America, draw on ground water and so respond more slowly to changes in rainfall....
Above is planetary vegetation in March 2000 and below is March of 2016. In case it isn't obvious Earth is drying up, Australia is the best bellwether. Other observations of reduced vegetation are South Africa, China, Western Europe, Eastern Amazon in South America, Eastern USA and Southern Canada.
