Climate Change

Alistair Strathern Excerpts

Thursday 19th March 2026 Commons Chamber

[Luke Murphy]

I fully agree with the hon. Member. I will say more about the impact on future generations later, but as she says, the burden will weigh heaviest on them if we do not take action today.

In my constituency of Basingstoke, we have already seen the reality of our changing climate, with more than 500 heat-related deaths in the south-east in 2022 alone. In 2023, extreme weather caused a landslip that severed our town’s rail connectivity for days, and in 2024, the south-east NHS saw a 13% increase in emergency hospital admissions for a respiratory condition linked to rising temperatures. Climate change is already affecting our health, our infrastructure and our economy, placing immense pressure on the public services we rely on. That is before we even consider the other serious economic risks posed by climate change.

The Climate Change Committee estimates that unchecked climate change could impact UK economic output by up to 7% of GDP by 2050. Businesses and investors already recognise that climate risk is economic risk, and small businesses are already feeling the impact. Shops on Pontypridd high street in Wales are finding it impossible to get insurance; flooding in Yorkshire and Cumbria is disrupting national supply chains; and whisky distilleries in Scotland face water scarcity. Failure to manage these challenges today will only increase costs and disruption later.

Climate change is also a critical matter of national security. For decades, and notably in the Pentagon’s 2014 quadrennial defence review, security experts have identified climate change as a major threat multiplier—it drives instability, heightens resource pressures and accelerates displacement. The Ministry of Defence’s 2021 “Climate Change and Sustainability Strategic Approach” document warns that climate change increases the risk of conflict through competition for scarce resources and undermines military effectiveness.

Then there is the impact on nature and our wider environment. There are those who try to separate the issues of climate and nature—the Reform party, for example, claims to care about nature while planning to tear up legislation, policies and investments to tackle climate change—but this is a false choice. Climate change is inseparable from the health of our wider environment; the stability of our forests, rivers, soils and seas is inextricably linked to our climate. As temperatures rise, we see damage to biodiversity and agriculture. The Government’s own nature security assessment warns that on our current trajectory, every critical ecosystem across all regions is heading towards collapse. Nature also plays a crucial role in safeguarding us. Our forests and wetlands absorb carbon; chalk streams, like the beautiful ones we have in Hampshire, support drainage; and urban trees help cool our temperatures. Protecting the climate and restoring nature must go hand in hand, as the resilience of one depends on the health of the other.

As always, my hon. Friend is making a powerful case about the breadth of issues that underline why it is so important that we act on climate change. It is often seen as a future issue, but my farmers are feeling the effects of volatile weather right now, just as some of my households felt the effects of rare flooding just last year. Does my hon. Friend agree that the land use framework published yesterday will be a really important document for ensuring we get adaptation and mitigation strategies right when it comes to protecting nature, as well as delivering the carbon reduction goals that are vital to ensuring we get our climate change action back on track?

[Luke Murphy]

I completely agree. If my hon. Friend will forgive the pun, the land use framework is a landmark document. It reflects the Government’s acknowledgement that the public understand many of the threats that we face and want to see climate action. Polling shows that 70% of the British public say that tackling climate change is important to them, with more than two thirds supporting ambitious action. For years, there was a broad cross-party political consensus on such measures. That consensus stretches back all the way to Margaret Thatcher, who said:

“The problem of global climate change is one that affects us all”.

That consensus delivered. We implemented the world’s first Climate Change Act in 2008 under Gordon Brown, and built on it under Theresa May. In 2015, we announced that we would phase out coal by 2025, which was brought forward to 2024. With the closure of Ratcliffe-on-Soar power station, the target was met. Domestically, we have more than halved our emissions since 1990 while growing our economy by nearly 80%. Clean energy drives economic growth, with the clean economy growing three times as fast as the rest of the economy.

Our leadership has secured action around the world. The Climate Change Act 2008 inspired nations such as Denmark, Mexico, Sweden, France, New Zealand, Ireland and Germany to adopt similar measures, and has contributed to reductions in emissions around the world. Successive Governments have shaped the global agenda, but that leadership is now at risk. The current leader of the Conservative party, the right hon. Member for North West Essex (Mrs Badenoch), would scrap the vital Climate Change Act, as would Reform, sacrificing the health of our environment, economy and society at home, and Britain’s global climate leadership and action abroad. Such action is reckless.

We have the capacity to drive meaningful progress at home and abroad, and we must continue to exercise our leadership. I was really proud to hear the Prime Minister say at COP30 that the UK is doubling down on the fight against climate change, and I am pleased that that commitment has been met by decisive action over the past 20 months

[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.
