Satellite data measuring Leaf Area Index shows a strong trend of global greening, not desertification. About 50% of land shows accelerated re-greening, including in europe, while only about 8% shows browning. There is no scientific case for desertification, which would be a surprise when we are pumping the atmosphere with greenhouse gasses.
