Climate Change

Debate between Alistair Strathern and Bill Esterson

Thursday 19th March 2026 Commons Chamber

[Bill Esterson (Sefton Central) (Lab)]

I congratulate my hon. Friend the Member for Basingstoke (Luke Murphy) on securing the debate. As far as I am concerned, we should debate this all day, every day, because the message needs to be heard loud and clear out there. Those who want to delay climate action are denying our children and grandchildren a future. They should be honest about their intentions and reasons for saying what they do. I will speak about three broad areas: science and the very real threat now and in the future; the myths and misinformation peddled by opponents of action; and the benefits of taking climate action, which my hon. Friend set out very well indeed.

I turn to the science on climate breakdown. We see the impact now, with heatwave days in the UK over the last few years, 88% of which would not have happened without the impact of climate change. There are 2,000 excess deaths a year in the UK alone as a result of excess heat, and 90% of our healthcare facilities are vulnerable to overheating. We face flooding and its consequences for food insecurity and the difficulty of growing crops—and that is just in this country, let alone around the world. Equally, we see heat and drought affecting our food production, and that threat to food production means rising prices and shortages.

There are impacts on biodiversity and on national security, with consequences such as conflict over scarce resources and migration because people are not able to live in certain places. The latest science suggests that unless we take action right now, parts of southern Europe—let alone the rest of the world—will be uninhabitable in as little as 15 to 20 years’ time, and by the end of the century billions of people will not be able to live where they are. That means they will not have anywhere to live. If we think we have a migration crisis now, we have seen nothing yet.

Let us deal with the myths. First, there is the idea that because we are responsible for only 1% of global emissions, we should not take action. Well, 30% of emissions come from countries that are responsible for less than 1% of emissions. If none of them take action, where is the motivation for China, India and other large countries—the United States is a bit of a lost cause at the moment—which have a far greater impact?

[Alistair Strathern]

My hon. Friend is making a powerful argument. Doubters of the net zero agenda often suggest that, because it is an international problem, we should go slower. Does he find it utterly bizarre that some suggest we can get other countries to go faster by going slower and engaging less ourselves? Actually, we need to be leading the way in the best traditions of Britain.

[Bill Esterson]

My hon. Friend is right. Actually, our global leadership through COP, which my hon. Friend the Member for Basingstoke mentioned, and the fact we have set our nationally determined contribution—unlike some countries—is hugely important. We were ahead of the game with the Climate Change Act 2008 and the 2050 net zero target set by Theresa May. My hon. Friend the Member for Basingstoke also mentioned Margaret Thatcher —when I came here, I never dreamed that I would be quoting her, but I have become more inclined to do so on this issue, if on no other. That fracturing of the consensus in the House is deeply worrying.
