As typhoons hit Southeast Asia and Jamaica and Brazil recover from recent storms, delegates at Brazil’s COP30 summit are confronting how to help vulnerable communities cope with worsening climate extremes.

The topic of "adaptation" has grown more important as countries fail to rein in climate-warming emissions enough to prevent extreme warming linked to increasingly frequent weather disasters across the planet.

A UN report last month said developing countries alone would need up to $310 billion every year by 2035 to prepare. 

Where that money will come from is unclear.

Ten of the world's development banks, under pressure to free more cash for climate action, said on Monday they would continue to support the need.

Last year, they channeled more than $26 billion to low- and middle-income economies for adaptation.

The fund, which also works to plug gaps in weather data for developing countries, hopes for country donations this week during COP30. 

On Monday, Germany and Spain pledged $100 million to a different effort, the multilateral Climate Investment Funds (CIF), which is financing projects to boost climate resilience in developing countries. 

The organisation's chief praised Brazil for featuring the issue as a COP30 focus, after years of seeing the issue slide down UN climate summit agendas.
