Summary

UNDP released the Human Climate Horizons dataset showing widespread projected declines in staple crop yields under high-emission scenarios; the UN also marked World Tsunami Awareness Day and urged investment in early-warning systems.

UNDP's Human Climate Horizons dataset, released ahead of COP30, projects that 161 of 176 countries analyzed will likely face declines in staple crop yields by the end of the century even after accounting for some farmer adaptation, the UN Spokesperson said (00:14:32). The briefing highlighted that cutting emissions to moderate levels reduces projected crop losses substantially compared with high-emission scenarios.

The spokesperson said further information is available from UNDP. The briefing also marked World Tsunami Awareness Day, with the secretary-general warning that tsunamis are rare but can be catastrophic and calling for investment in early warning systems; the UN aims to achieve early warnings for all by 2027 (00:15:31).

No policy decisions or funding allocations were announced at the briefing relating to the dataset or the tsunami awareness initiative.
