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.
