The Primer now looks at the main consequences of climate change, with a focus on sea-level rise, temperature change, precipitation change, resilience, and extreme events. The relationship between consequences and the extent of mean global temperature rise is shown in figure 2.4. When global annual temperature increases, several effects are likely to occur. The figure shows the potential impacts of a 5°C change in temperature to the water, ecosystems, food, coasts, and health sectors.
