This document summarizes key findings from the Sixth Assessment Report by the Intergovernmental Panel on Climate Change. It finds that climate change impacts are intensifying with every increment of global warming and will profoundly affect people and nature. While options exist to mitigate climate change by cutting emissions nearly in half by 2030, current efforts are insufficient. Fairness is needed as those contributing least to the problem are often most vulnerable to its impacts. Integrating climate adaptation and resilience measures with development can provide wider benefits while enabling climate action through political commitment and international cooperation.

safer, sustainable world
• Scale up practices and infrastructure to
enhance resilience
• Cut global GHG emissions by nearly half
by 2030
• Action required along numerous

one of the
solutions
• Those who contributed the least to climate
change are often the most vulnerable to its
impacts.
• Millions exposed to acute food insecurity,
reduced water security.
• Biggest impacts in parts of Africa, Asia,
Central/South America, LDCs, Small Islands,
Arctic.
• People in highly vulnerable areas up to 15x
more likely to die in
fl
oods, droughts, storms
(compared to those in in most resilient areas)
