Climate change, the group noted, will reduce yields of major crops by up to two per cent each decade for the remainder of this century. (One of the reasons for this is that heat waves, which will become more common as the world warms, depress the yields of staple crops like corn.)

Since the global population is projected to grow throughout the century — to eight billion by 2025, nine billion by 2050, and almost eleven billion by 2100 — this is obviously rather bad news. At the same time, the incidence of flooding, drought, and general weather-related mayhem will increase, and already-vulnerable populations will be pushed closer to the edge, or, quite possibly, over it. Conflict is bound to ensue. Climate change “will increasingly shape national security policies,” the report warns.

Meanwhile, as bad as things look for humans, the prognosis for non-humans is, in many ways, worse. Under all the scenarios that the I.P.C.C. panel considered, including an implausible one in which the world imposes drastic limits on carbon emissions right now, a “large fraction” of terrestrial and freshwater species face elevated extinction risks.
