The next major United Nations meeting on climate change, known as COP29, is about to get underway in Baku, Azerbaijan. These annual meetings are the key international summits as the world attempts to address the unfolding climate crisis.

The annual U.N. climate summit began on Monday with some prominent leaders planning to skip the event ahead of tough talks on finance and trade, after a year of weather disasters that have emboldened developing countries' demands for cash.
