Mr. Nasheed brought global attention to his sinking archipelago nation in the Indian Ocean by holding an underwater cabinet meeting in 2009. We should find a way out of the situation.

Poor nations are locked in a Sisyphean trap because they have to borrow money to ward off rising seas and storms, only to have them destroyed by climate change. The debt is often left to be borrowed again.

According to David Theis, a spokesman for the World Bank Group, climate change is having a disproportionate impact on poor and small-island developing nations.

The smoke from the wildfire is polluted. According to new research, smoke from wildfires may be reversing decades of improvements in Western air quality.

Many developing countries and low-lying island nations want an international fund to compensate them for losses and damage caused by climate change. The United States, Europe and other wealthy countries that have historically emitted the bulk of greenhouse gases have opposed the creation of such a fund because they fear being held legally liable for the rising costs of disasters.

John Kerry, the US special envoy for climate change, said at a New York Times event last month that honesty is the most important thing we can do. We can help people adapt to the damage that has already been done. The government in the world that has trillions of dollars is what it costs.

Mr. Nasheed believes that focusing on a debt swap could be a better way to go about creating a new fund. He said that a lot of funds have gone unfilled.

If debts were shaved by 30 percent and money was instead invested in projects such as improving water systems or protecting shorelines from hurricanes, it would have a huge impact.

A spokeswoman for the V20, a coalition of finance ministers representing vulnerable nations, said that the countries were discussing stopping debt repayments until the banks addressed climate change.
