Flip or flop - have the COP meetings done any good for the climate?

1990 - Sundsvall, Sweden: The UN's Intergovernmental Panel on Climate Change (IPCC) presented its first scientific report on climate change at a meeting opened by then Prime Minister Ingvar Carlsson.

1995 – Berlin, Germany: The first UN climate summit was held. Since then, the meetings are basically held every year in different places in the world.

2015 – Paris, France: Nearly 200 countries signed the Paris Agreement. The goal is to limit global warming to well below 2 degrees, preferably to no more than 1.5 degrees.

All countries must contribute to reducing emissions, but based on different conditions and responsibilities.
