The world's poorest people, increasingly buffeted by storms, floods and droughts, have been getting less than 1 U.S. cent (¥1.1) a day each in international help to protect them from wild weather and rising seas as the Earth heats up, aid group Oxfam said Monday.

Its analysis of global funding for developing countries to adapt to climate change was released as world leaders gathered in New York for a U.N. summit where they have been asked to set out how they will do more to rein in global warming.

Poorer nations — many in places where climate change effects are hitting the hardest — have long demanded more financial support so they can build stronger homes, plant hardier seeds on farms, put in irrigation and warn citizens of dangerous weather.
