a) Anger: Some people are angry, because politicians always say what we have to do to change the world but they don't do anything. They drive big cars and fly around the world.

Responsibility: There are people which feel responsible for the climate change and want to do something to reduce the global warming.

Hope: Most people aren't very hopeful for the future. They don't believe that it will getting better.

Indifference: Many people don't know what happens in the world, so they don't care about the climate. They only want to live and don't think about resolving the problem.

b) We feel uncertainty. We don't know how the future will be and if the climate is really that bad, like people say.
