A Guardian survey of leading climate scientists revealed their despair about the future. John Coghlan, Rachael Orr, Natalie Bennett, Dr Robin Russell-Jones and Gregory Johnson find reasons to keep on fighting

I must commend the Guardian and Damian Carrington for the excellent reporting on the views of leading climate scientists (‘Hopeless and broken’ Why the world’s top climate scientists are in despair, 8 May). I have experienced climate despair, which has led me to take part in non-violent protests, and I can certainly bear witness to the fact that this kind of collective action goes a long way to offset the despair. However, protest is not for everyone. There are other ways to play our part.

We can help to accelerate the energy transition. Some 51% of final energy consumption is for heating and cooling, and 32% is for transport, according to the International Energy Agency, so we must ditch the old boiler and invest in a heat pump, and swap our petrol car for an electric model. By fitting solar panels, we can also generate renewable energy to power both transport and heating. Having done these things myself, I have found that the lightening of my carbon footprint brings with it a lightening of climate despair.
