Although the global mean amount of days above freezing will grow by up to 7 percent, suitable growing days will decline globally by up to 11 percent. Areas in Russia, Canada, and China are predicted to gain suitable plant growing days, but the rest of the planet will experience declines.

Tropical regions could lose up to two hundred suitable plant growing days per year. These changes will affect most of the earth’s ecosystems.

2,1 billion (~30%) of the poorest people on the planet helpless to changes in the supply of plant-related goods and services.

Human vulnerability is quantified as the combined effect of dependency, exposure, and adaptability, which are displayed along a red-green-blue gradient (colors in the triangle correspond to colors in the map). Points in the triangle represent each of the 194 countries analyzed, with the positions of the United States (U), China (C), and Brazil (B) indicated for reference.
