Desertification has always been a serious challenge for human beings, especially in arid and semi-arid regions. Projections from CMIP5 support the expansion of arid and semi-arid regions with increasing greenhouse gas concentrations. Interestingly, besides inducing a stronger greenhouse effect, increasing carbon dioxide is also leading to global vegetation greening, especially in high latitudes, by the fertilization effect. However, it is still unknown whether greening in high latitudes could affect mid-latitude deserts.
