We projected changes in weather extremes,
hydrological impacts and vulnerability to food
insecurity at global warming of 1.5°C and 2°C relative
to pre-industrial, using a new global atmospheric
general circulation model HadGEM3A-GA3.0 driven
by patterns of sea-surface temperatures and sea
ice from selected members of the 5th Coupled
