Nonetheless, Biden insisted it was up to the leaders in the room to take on the existential crisis. It’s critical that developing countries have “enough firepower and access to capital” to combat climate change and protect themselves from its effects, Biden told heads of government at a working session. “We need to continue to give breathing space to countries that are weighed down by debt,” Biden said, adding, “We as leaders need to find ways to flow money into their economies.
