PARLIAMENTARY DEBATE
Extreme Climate and Weather Events: National Resilience - 10 March 2026 (Commons/Commons Chamber)
Debate Detail
We know that extreme weather events are becoming more frequent, and 2025 was the warmest year on record. Four of the five warmest years since 1884 have occurred in the past five years, and the record for the highest UK annual mean temperature has been broken six times since 2000. Last year, the Met Office warned that the likelihood of experiencing temperatures above 40° is now 20 times greater than it was in just the 1960s. In the summer, hosepipe bans are now common, and we had one in Cornwall, despite our copious rainfall, that went on for months and into the autumn of 2023. This winter was also the duchy’s wettest since records began in 1836. Cardinham had 55 consecutive wet days, and we were battered by three storms in quick succession: Goretti, Ingrid and Chandra.
In its response to the UK’s third national adaptation plan, the Climate Change Committee called on the Government to urgently refresh NAP3, as it fell short of preparing the UK for the climate change that we are experiencing, and adaptation progress is too slow, has stalled or is sometimes heading in the wrong direction. We are still reliant on short-term emergency measures, which cost more in the long term.
The EFRA Committee, on which I sit, has an ongoing inquiry into climate and weather resilience. Farmers are heavily affected by extreme weather events, and that impacts on our food security and prices. British farm businesses were down £800 million in 2025 because of crop failures, and three of the five worst harvests on record have occurred since 2020. However, the risks go beyond farming. According to the Environment Agency, 6.3 million homes and businesses are at risk of flooding, but over the past decade one in 13 homes were still built in high-risk flood zones.
Businesses that rely on electricity and broadband are paralysed by outages during extreme weather events, and hospitals risk losing power or water. Heavy rainfall has even led to overflowing septic tanks and sewage spilling out on to streets in Cornwall, creating serious risks to public health. So much of Cornwall’s economy depends on our coast. When beaches, cafés, coastal roads and car parks are under managed realignment in the new shoreline management plan epoch, coastal places will lose their staple industries, and entire communities face existential threats from rising sea levels and coastal erosion. A lot of work is being done across Government, particularly on the water industry and flooding preparedness, which I welcome, but we need to protect communities from the inevitable march of climate change and act with greater urgency.
The urgency of the situation was obvious when Storm Goretti struck Cornwall on 8 and 9 January 2026. It triggered a rare Met Office red warning, with gusts of around 120 mph, and inflicted severe damage on our homes and infrastructure. We lost over 1,000 trees, 121,000 customers lost power, and thousands lost access to clean water. Roads were blocked, communities cut off, and schools, care homes and hospitals faced unprecedented strain.
Utility teams worked around the clock with local authorities, engineers and emergency responders to restore essential services. National Grid brought in 1,350 staff from all across the country, and tree surgeons were deployed, but we saw failures in the systems designed to keep people safe. The storm was a wake-up call. It exposed vulnerabilities in our infrastructure and emergency planning that could affect anywhere in the UK as extreme weather becomes more frequent.
I have had wash-up meetings across my constituency since the storm, and we have been talking to Ministers. I welcome the suggestion that Cornwall could serve as a pilot area for emergency storm resilience measures, some of which I will talk about now.
One of the most profound lessons that we must learn from Storm Goretti is to increase communications infrastructure, particularly in rural areas. Many of our constituents were left without power or broadband in areas that have weak or no mobile phone signal, so they struggled to get help. Although we are frequently told by the four network providers that they have 99% 4G coverage, that does not ring true to anyone in Cornwall, where we struggle to get a signal on a regular basis.
When Goretti hit, the Cabinet Office activated the national alert messaging. That was important and successful as an early-warning system, but it was impacted by the patchy mobile coverage. We need a more truthful method of measuring mobile coverage, and a means of applying pressure to the providers, so that they meet their obligations. Goretti also exposed the fact that most mobile masts do not have back-up generators or battery reserves, making them vulnerable to power loss. This contrasts with the expectations placed on water and electricity companies, which operate under more established resilience duties. Telecoms are just as essential, and the civil contingencies framework should reflect that in practice, not just in statute.
During Goretti, many residents with no internet or mobile signal found that digital landlines did not work without power. Ofcom’s rules require only one hour of battery back-up for vulnerable customers, which is inadequate. An Ofcom technical report from last year noted that about two thirds of the population would be able to make emergency calls in a power outage of under an hour, but the number who could do so after six hours was redacted, and was described as being “far fewer”.
On broadband, Openreach and service providers do not have a good system of fault notification. During Goretti, they were unaware of faults, and the notification of faults solely through third-party providers did not work well, as residents struggled to get through. A more direct method of reporting faults and an interactive map, maybe like the one that National Grid uses, showing the location of faults and realistic time estimates for restoration, would be helpful. That is particularly pertinent in Cornwall, as last month Wildanet withdrew from several Project Gigabit contracts, leaving nearly 8,000 rural premises in limbo, without the high-speed broadband that they were promised. We must not leave them behind.
We must also ensure that our transport systems are robust. We have talked about the recent storms damaging Dawlish. The sinkhole between Dawlish and Teignmouth also led to closure of the rail line, which is the only line in and out of the far south-west. When the Goretti alert went out, all Cornwall’s MPs were stranded in the south-east. I could not get home, and we had to hire a car the next day. My son was alone in the house, 300 miles away. The Valentine’s day storm of 2014 led to the far south-west being cut off for eight weeks. In that time, the region lost anywhere between £60 million and £1.2 billion, according to Devon Maritime Forum. Since then, work has been done to make the line more resilient, but the strategic long-term plan that we have discussed for rail across the south-west is an urgent priority, as without it, our economy will stagnate.
I will also mention energy resilience. I support the Government’s ambition to increase the UK’s energy security by investing in renewables. I was so pleased to attend the launch of the local power plan last month, which will allow communities to own and benefit directly from the energy that they produce. Locally produced and managed power will be more resilient.
Rural areas such as mine have a high proportion of properties off the gas grid. Approximately 14% of Cornish households rely on oil for heating, compared with a national average of below 5%. There is an alternative in the form of hydro-treated vegetable oil, which has been trialled in Cornwall, but the incentives are not there. Meanwhile, I have spoken to constituents who have been refused planning permission to put solar panels or turbines on properties that are listed or in conservation areas, as many in our area are. Ensuring that as many people as possible can benefit from local renewable energy will allow us to be more resilient to shocks.
An issue that became apparent during the storm was the lack of community emergency plans. In my constituency, some parishes had them, and some did not, but even the existing emergency plans did not work if people did not know who should be putting them into action. The will was there, and the Cornish spirit came to the fore—neighbours checked in on each other, and farmers helped to clear fallen trees—but there was an overall lack of co-ordination.
Every parish should be able to identify a community hub that residents can go to in an emergency. It should have a generator, battery packs, blankets, food, and a pre-registered list of volunteers. I know that parishes in Cornwall are considering that, but it could be encouraged across the UK and co-ordinated at a higher-tier council level—maybe across a local or national level. We could look again at the Bellwin scheme, and at how category 2 and category 1 responders respond to these issues.
Finally, there is a conversation to be had about personal resilience. We all need to be more prepared. Having a basic emergency kit sounds simple, but it makes a big difference.
Storm Goretti highlighted to all of us how essential it is to improve our resilience in the face of extreme weather events. Cornwall is an ideal location to pilot national resilience measures, and I hope that the lessons learned from the storm will enable us across the country to become better prepared for extreme climate and weather challenges.
The Government’s first responsibility is to keep the country safe. We are absolutely committed to taking all measures necessary to build national resilience to external shocks or threats that could cause disruption to our way of life, now and in the future. The UK benefits from world-leading weather warning and information services, which provide information and advice to the public when bad weather is forecast. Weather events can have wide-ranging impacts on communities, including on homes, health, transport, energy and communications, and the relevant lead Department for each of those affected areas has a responsibility to work closely with stakeholders on the recovery from an emergency.
We are absolutely committed to building resilience on both a national and a local level, and while we acknowledge the Climate Change Committee’s assessment of the third national adaptation programme, we are not simply relying on short-term measures. Alongside delivering the actions in the programme to address climate risks to the UK, we are taking significant, long-term action now to become more resilient to the effects of climate change, such as flooding and overheating. We are building new reservoirs and cutting water leaks to help secure our water supplies. This includes a record £10.5 billion investment in flood defences to protect 900,000 properties.
I was privileged to meet community members and first responders shortly after Storm Goretti, and to hear at first hand about the challenges they faced. I was very pleased last week to see His Royal Highness the Prince of Wales visit Helston, in the constituency of the hon. Member for St Ives (Andrew George), shining a spotlight on the strong spirit and resilience of the people of Cornwall.
In the period preceding the storm, our world-leading weather warning service played a significant part in the initial Government response. The storm made landfall on Thursday 8 January; the Met Office issued a rare red national severe weather warning across the Isles of Scilly and parts of Cornwall. The storm brought a combination of heavy rain, significant snow and strong winds to England and Wales. Emergency alerts were quickly dispatched to half a million residents in Cornwall and the Isles of Scilly, advising them to remain indoors until the danger had passed. The conditions resulted in widespread power outages and disruption to transport networks. The national response was managed by the Cabinet Office, which co-ordinated meetings with health and environmental experts and senior Government officials. The Cabinet Office has committed to a comprehensive review of the response to Storm Goretti, which aims to ensure that lessons are captured across Government to improve our response to future severe weather events.
The Government are also acutely aware of the challenges faced by British farmers due to extreme weather, which can impact harvests and consequently influence food prices. Despite these challenges, the UK maintains a resilient food supply chain that is underpinned by diverse sources; robust domestic production; and reliable import routes. During a recent visit to Aberystwyth University, I visited the Institute of Biological, Environmental and Rural Sciences, a leading research institute dedicated to advancing the sustainable production of food, feed, and plant-based resources. I also met Aled Jones, the former president of the National Farmers’ Union Cymru, and we discussed the vital importance of securing our nation’s food supply. I recognise that the Government must work collaboratively with farmers and the NFU to ensure that our food supply is safeguarded for the long term.
As has been mentioned, our telecommunications networks are a vital part of the UK’s critical national infrastructure and our emergency response in weather-related crises. They support the functioning of essential services and keep people connected when they need it most. The public switched telephone network often relies on overhead cables that can easily be damaged during severe winds, and most handsets rely on power supplies. Telecoms companies are upgrading landlines from analogue to digital, with over two thirds of lines across the UK already having been migrated. We recognise that telecoms resilience is underpinned by a resilient power supply. Through close co-ordination with the energy sector, the emergency planning community and industry, we are strengthening back-up power arrangements, improving situational awareness, and ensuring that the sector is ready to activate mitigation measures when risks escalate.
