Wera Hobhouse – 2022 Speech on Climate Change and Human Security

The speech made by Wera Hobhouse, the Liberal Democrat MP for Bath, in Westminster Hall on 3 November 2022.

I beg to move,

That this House has considered climate change and human security.

It is a pleasure to serve under your chairship, Mr Efford. I am grateful to the Backbench Business Committee for granting me this debate, which follows on from the debate we had last year on global human security. There is an urgent need to consider how compatible the UK’s security approach is with tackling the climate emergency.

The climate threat is one of the largest threats facing humans. Too many politicians are still treating our vital net zero targets, which will keep temperature rises below 1.5° C by 2050, like buses: if we miss one, we can just catch the next. We must comprehend that there will be no coming back and no next time if we miss net zero by 2050. Doing so would be catastrophic, exacerbating worldwide challenges such as rising sea levels and the loss of natural resources. It would contribute to increased conflict, poverty, malnutrition and gender inequality. Some 1.2 billion people are set to be displaced due to climate change by 2050. If people are concerned about migration now, they have not seen anything yet.

Climate change can no longer be seen as a problem for the future; it is having a material impact on people worldwide now. Between 1970 and 2019 global surface temperatures increased at a higher rate than in any period over the past 2,000 years. Since 1950 the global number of floods has increased by a factor of 15 and wildfires have increased by a factor of seven. The abnormally hot and cold temperatures experienced worldwide contribute to as many as 5 million deaths a year—that is now, not in the future. Climate change is causing havoc around the world. Last month a new study of the Greenland ice cap concluded that a major rise in sea levels of 27 cm is now inevitable, even if fossil fuel burning worldwide were to end overnight. That is terrible news for the 150 million people globally who live less than 1 metre above sea level.

Earlier this year Pakistan was just one of the countries across south Asia that experienced a heatwave that took temperatures over 50° C. That country has now faced floods that have directly affected 33 million people, causing at least $10 billion in damage. Spring rains in Somalia have been the weakest in 60 years, contributing to drought and famine across east Africa, which has put 22 million people at risk of hunger and starvation. Devastating climate change effects can also be seen at home. The World Weather Attribution group found that human-induced climate change made the recent UK heatwave at least 10 times more likely. The Joint Committee on the National Security Strategy has declared that the UK’s critical national infrastructure is

“very vulnerable to extreme weather and other effects of climate change”.

Over 570,000 UK homes are not suitable for high temperatures.

We are not just in the middle of a climate crisis; nature is in crisis too. Our way of life, especially in developed nations, is exploiting our global resources in a way that is becoming increasingly unsustainable for our planet. As nature declines, so does the quality of human life. Pollution and poor air quality alone cost millions of lives every year across the globe. We in the UK are not excluded, and all those things beg the question of whether the way in which we currently look at security policy limits the extent to which the Government keep us safe.

We are used to the Government declaring that their first duty is to keep citizens safe and the country secure. However, the way that they define our security matters. For years, we have thought that security is about the risks to our nation from hostile actors. That narrow conception risks sidelining the climate threat. The Russia-Ukraine war has shown that temptation. We have already seen countries such as Germany move back to using coal. Even in the UK, the former Prime Minister used the war to lift the fracking ban, and announce more than 100 new licences for oil and gas drilling in the North sea. It is of course important that we are properly aware of and equipped to tackle risks from hostile actors. However, the need for energy security should never lead us to downplay the existential threat that the climate crisis poses to humanity.

The term “human security” was first championed by the United Nations Development Programme in its annual report on human development. It is about security for people, and emphasises economic, food, health, environmental, personal, community and political security. Human security puts the experience and wellbeing of the individual at the centre of security policy, prioritises international co-operation over national competition, and focuses on the shared security of all humanity. The concept of human security is acknowledged by multiple influential international organisations, including the UN, the International Committee of the Red Cross, and the World Bank.

The climate threat goes beyond national borders, and has far-reaching consequences. State-centric security practices cannot comprehend the vast array of threats that we face. We must move towards a model of security that cares for people above all else. If we do so, the true scale of the climate threat is thrust into the spotlight. Countries must be incentivised to prioritise it. After all, the sooner we act, the more people can be protected. The Intergovernmental Panel on Climate Change suggests that limiting global warming to 1.5°C rather than 2°C may save around 520 million people from frequent exposure to heatwaves.

Putting climate action at the heart of any Government plan is the best way to protect the UK against hostile actors. Putin’s war has shown how long-term dependence on fossil fuels can power hostile regimes. Russia has used Europe’s dependence on its natural gas as a weapon. If the UK had moved towards renewables harder, faster and earlier, Putin would not have that leverage, and our constituents would not be paying the price for the war.

What must be done to protect people from the climate threat? How can a human security approach help the world to reach net zero? A human security approach addresses the root causes of vulnerabilities, and takes early action on emerging risks. Threats such as climate change are predictable and incrementally destructive, yet consecutive Governments have failed to do anything meaningful about them in the long term. The worst impacts of climate change stretch well beyond average election cycles. The evidence is clear that the costs of climate change are dwarfed by the consequences of inaction.

The country’s finances are already straining under the weight of recent Conservative Government incompetence. They are set to shatter completely if we do not get a grip of the climate emergency now. The London School of Economics predicts that we will lose £340 billion a year by 2050 because of this Government’s refusal to take action fast enough. University College London issued similarly stark warnings about the world’s financial system, which is set to lose 37% of global GDP by the end of the century as a result of the climate crisis. Such losses will be unrecoverable.

That economic dark age is not inevitable. A green future should be seen as a prosperous one. A recent University of Oxford report states that if we move to a decarbonised energy sector by 2050, the planet will save $12 trillion. A net zero economy is an opportunity for this country. We can be the world leaders in this financial age.

Change must begin at home. The Liberal Democrats are calling on the Government to announce an action plan, backed by a £150 billion public investment programme, to fire up progress to reach net zero. Our plan proposes a major restructuring of the UK’s economic and financial model, and investment in renewables is vital to it. Renewables are the world’s cheapest source of energy now. Investing in them is good for the planet. It secures our energy and protects our wallets. As the Committee on Climate Change notes, reducing demand for fossil fuels will help to limit our constituents’ energy bills.

The UK must invest in renewable power so that at least 80% of electricity is generated from renewables by 2030. That is a tough target. We set the targets, but fail to deliver them. We must press ahead to make more of our renewable energy targets. The Government must now deliver on the many promises and targets they have set for the nation. We desperately require a department at the heart of Government that is dedicated to co-ordinating the many fragmented activities across Government and society. We urgently need to bring back the Department of Energy and Climate Change, which provided essential leadership during the coalition years. Will the Minister tell us whether the Government have any intention of re-establishing such a Department, given that we are falling behind in the delivery of our net zero targets?

The climate crisis should be at the forefront of every decision the Government make between now and the time that net zero is reached. We Liberal Democrats propose having both a department of climate change and a Cabinet chief secretary for sustainability to co-ordinate all Government activity in response to the climate emergency. That would ensure that climate change is given the priority it deserves in every Government action and in every Department.

The UK must put aside its damaging approach of isolation and the language of division. Climate change is a huge problem that can be solved only through collaboration with everybody else. I recently met John Kerry, who noted that the approach to climate change in the US changed completely when Joe Biden became the new President. Leadership matters, and we need such leadership from our Government now.

Ahead of COP26, the then Chancellor, the right hon. Member for Richmond (Yorks) (Rishi Sunak), cut air passenger duty on domestic flights. Last May, he brought in a windfall tax that incentivised firms to invest in fossil fuel extraction. During the latest Conservative leadership campaign, he pledged that he would make it more difficult to build onshore wind farms in England. To have our new Prime Minister effectively dragged along to COP27 is humiliating for the UK. That is not the leadership we need from our new Government. The UK must lead from the front to encourage others to act. As the Committee on Climate Change suggests, it should prioritise strengthening the ambitions of countries around the world while preparing for a focus on climate finance and adaptation at COP27 next week, and COP28 next year.

For too long our response to climate change has been complacent. Climate action cannot be ditched in favour of status quo interests. After all, people can never be secure in a world ravaged by extreme weather events. It is time the world moved away from viewing our security simply at state level and started looking at the bigger picture. We cannot be safe until the world is safe from the worst fallouts of the climate emergency. The floods, heatwaves, wildfires and storms of 2022 are alive in our minds. There is no better time than now to put in long- lasting protections to save current and future generations from the crippling consequences of climate change.

Climate change must become part of the UK’s security thinking. The Conservatives must get a grip and take the lead on this issue. I hope that the UK Government will look at my recommendations. We are all in a war against climate change and must begin to treat it as such.
