WASHINGTON — A report commissioned by federal regulators overseeing the nation’s commodities markets has concluded that climate change threatens U.S. financial markets, as the costs of wildfires, storms, droughts and floods spread through insurance and mortgage markets, pension funds and other financial institutions.

The first famines of the coronavirus era could soon hit four chronically food-deprived conflict areas — Yemen, South Sudan, northeast Nigeria and the Democratic Republic of Congo — the top humanitarian official of the United Nations has warned.

As the United States withdraws from membership in the World Health Organization, the Trump administration will redirect $62 million still owed for this year’s dues to other health-related causes also under United Nations auspices, State Department officials announced on Wednesday.

Most of the redirected money will go to children’s immunization and influenza surveillance, officials said. But the United States Agency for International Development will continue with plans to give $68 million to the W.H.O. to support its work in Libya and Syria, and on polio eradication in Pakistan and Afghanistan.
