The UN Environment Programme's Adaptation Gap Report 2026 says global warming is
expected to exceed the 1.5°C threshold. It finds adaptation finance for
developing countries remain severely inadequate, adaptation actions are
progressing slowly, and climate-related loss and damage are continuing to rise.
The report estimates developing countries will need about $305 billion per year
in adaptation funding by 2035; even if international public adaptation finance
were tripled, it would meet only roughly 20–30% of that need.
