let s get an expert opinion from dr isabella velicogna, professor of earth system sciences at the university of california. she s spent her career monitoring ecosystem response to climate change. the world could or will still warm by 3.2 degrees this century, we are told but can you give us an insight into what that might look like? it may look pretty terrifying, but we don t have to think about that because we are going to do better. what it looks like, we will have disappearing species, in terms of animals, vegetables, but i am a very strong believer about what we can do right now can make a difference and we are not going to get there. is
