TACLOBAN, the Philippines — After touring miles of roofless homes and shattered shantytowns destroyed by Typhoon Haiyan last month, Secretary of State John Kerry announced on Wednesday that additional American humanitarian aid would be sent to the Philippines. He called the giant storm a warning of extreme weather in a warming world.

“No words can do justice to the level of destruction we’ve seen in this entire community,” he said.

For the most part, the severe shortages of food and clean water in the two weeks after the typhoon made landfall on Nov. 8 have ended. But four million people lost their homes to the tsunami-like storm surges or gusts that reached 200 miles an hour, and the effort to rebuild has barely begun.

The Philippine government raised the official death toll to 6,092 on Thursday, with 27,665 injured and 1,779 missing. Local officials say the number of dead will continue to rise as more bodies are found.

Running water has been restored in some central areas of Tacloban, but large areas of Leyte and Samar Islands still have none.
