Question: How soon do you think climate change will become a serious problem

Oliver Andrews answered on 5 Mar 2019:

We are already experiencing the effects of global warming, however it can be very difficult to say that a particular event (like a drought or heat wave) is definitely caused by climate change. The future depends very much on what actions we take now to reduce our pollution. Many countries have signed up to an international agreement (called the Paris Agreement) which aims to limit global temperature increases to 2 degrees above what we call the pre-industrial level.
