In summary, risks to unique and threatened systems (RFC1) are higher at recent and projected levels of warming than assessed previously (very high confidence); risks associated with extreme weather events (RFC2) are assessed comparably to AR5 and SR15 at recent and low levels of warming, but notably much higher at projected warming above 1.8°C (medium confidence); risks associated with distribution of impacts (RFC3) and global aggregate impacts (RFC4) are similar to SR15 and higher than AR5 above 2°C (medium confidence); and those associated with large-scale singular events (RFC5) are similar to SR15 and higher at both recent and projected warming than AR5
