A global average temperature rise of just 0.3 °C will “significantly” change regional average temperatures, according to a study by US scientists. The study, which also reveals that a rise of at least 2.5 °C is needed to affect regional precipitation significantly, shows the consequences of even small deviations from climate-change targets.
Most policy targets for climate change revolve around global quantities such as average surface temperature, radiative forcing, or the concentration of greenhouse gases such as carbon dioxide. The only internationally agreed goal is to limit global average temperature change to 2 °C above the pre-industrialization level. […]
