Labour — Doncaster North

Speaking in the House of Commons on 25 November 2025

Debate

COP30

Contribution

I have had this exchange with the hon. Gentleman before—he is too pessimistic. If we had taken that approach before, we would be heading for 4°C or 5°C of global warming. Yes, it is true that the central scenario is somewhere between 2.3°C and 2.5°C depending on which figures one looks at, but the whole point is to bring the numbers down. People talk about negative tipping points, and we are right to be worried about those, which is why, I am afraid, we cannot just let it happen—it would be a disaster. We should also think about positive tipping points. On solar energy in the past decade, for example, we have exceeded the forecasts that the IEA and others had. We need to move towards those positive tipping points. I am not giving up on 1.5°C, but I make this point to the hon. Gentleman: every fraction of a degree that we reduce warming will save many lives across the globe, prevent many disasters and reduce the costs that future generations face. I agree with him about investing in adaptation, but we have got to do both.
