As Pakistan swelters through unprecedented heat this week, experts give a terrifying insight to the fatal effects of climate change.

According to the Climate Change Committee (CCC), extreme heat could kill around 11,000 people per year in the UK alone by 2050. 

The CCC warns that government is failing to brace the UK for ‘tomorrow’s disaster’ of floods, heatwaves, drought, wildfires and more dire climate effects.

From schools to hospitals, houses and railway lines, the UK infrastructure is not prepared for the effects of rising temperatures, it says. 

‘We have seen in the last couple of years that the country is not prepared for the impacts of climate change,’ said Baroness Brown, chair of the CCC’s adaptation committee.

‘We know there is worse to come, and we are not ready – indeed in many areas we are not even planning to be ready.’ 

It comes as unusually warm conditions spread over the Middle East and South Asia, including Pakistan, Iran, India and Saudi Arabia. 

In Pakistan, temperatures rose to 118°F (47°C) at the weekend and could near the global record for April of 122°F (50°C).

The CCC assessment looked at 46 areas where climate adaptation needs to be delivered, from food security to transport, buildings, health & wellbeing and ‘community preparedness and response’.

Overall, it found only good progress in plans and policies for only three – making rail and strategic road networks reliable and ensuring risks were properly disclosed and managed by financial institutions. 

But not a single measure – from ensuring resilience in nature and farmland to water, food and energy supplies – was making good progress, with 12 areas rated insufficient. 

Delivering change had actually worsened in the water sector because of a lack of decent plans to cut leaks and reduce water demand in the face of drought. 

Authors say there is now ‘unequivocal evidence’ that climate change is making extreme weather in the UK more likely and more extreme, pointing to recent events.

During 2022’s heatwave, temperatures topped 40°C (104°F) for the first time ever, leading to nearly 3,000 deaths that were otherwise preventable. 

In addition to the heat-related early deaths, the heatwave huge pressure on emergency services and halted operations in hospitals. 

Climate change is not only responsible for higher temperatures, but other unpredictable weather events like tropical storms and floods.

Highlights from the report 

  • 11,000 people in the UK could die from climate change by 2050
  • 6.3 million properties in England are in areas at risk of flooding 
  • Over half of England’s top quality agricultural land is at risk of flooding today 
  • Unchecked climate change could impact UK economic output by up to 7% of GDP by 2050 

Also, climate change causes more ‘wildfire-conducive conditions’ – making fires more likely to start and spread. 

The report warns 6.3 million homes and properties in England are now at risk of flooding, which is set to rise to eight million (one in four) by 2050. 

Already, record wet conditions from 2022-2024 caused devastating flooding and crop damage, affecting food production worldwide. 

Half the UK’s prime agricultural farmland is at risk of flooding, which is set to worsen, while schools, hospitals and care homes are among the most vulnerable to impacts such as heatwaves, the committee warned. 

Threat of flooding will be especially severe at cities and towns around the UK’s coastline due to steadily rising sea levels, which is due to melting of glaciers and ice sheets. 

Aside from the more obvious risks, the societal effects of climate change will be far-reaching, the report warns. 

For example, extreme heat will continue to disrupt infrastructure systems by making power lines sag, causing blackouts, and making railway lines expand, causing equipment damage and delays.

Without action on climate change, up to 7 per cent of the UK’s economic output could be hit by 2050, creating ‘challenges for driving sustainable long-term growth’. 

As there had been no improvement since its last assessment in 2023, CCC accused the new government of failing to deliver the change in approach needed. 

Baroness Brown said: ‘People are worrying about the impacts of extreme weather, worrying about food prices. People are worried about what’s going to happen to their vulnerable friends and relatives.

‘Despite all this, we are seeing no such change in activity from the new government, despite the fact that it’s clear to my committee, it’s increasingly clear to the public that the current approach to adaptation policy just isn’t working.

‘Our message is the country is at risk, people are at risk, and there’s not enough being done.’

She added: ‘We can’t wait to take action, this is not tomorrow’s problem, it’s today’s problem, and if we don’t do something about it, it will become tomorrow’s disaster.’

A government spokesperson said they would carefully consider the findings of the committee’s report.

They added: ‘Alongside our transition to become a clean energy superpower and accelerating towards net zero, the Government is taking robust action to prepare for the impacts of a changing climate.

‘We are investing a record £2.65 billion to repair and build flood defences, protecting tens of thousands of homes and businesses and helping local communities become more resilient to the effects of climate change such as overheating and drought.’

How does climate change make weather worse? 

As scientists already know, climate change results in more intense rainfall because warmer air can hold more moisture. 

And because rainfall is increasing on average across the world, the chances of flooding are getting higher. 

Climate warming also increases evaporation on land, which can worsen drought and create conditions more prone to wildfire and a longer wildfire season. 

Earth’s warmer and moister atmosphere and warmer oceans are linked with stronger and more intense hurricanes.

In addition, rising sea levels – partly caused by melting ice in the poles – increases the amount of seawater that is pushed on to shore during coastal storms, which, along with more rainfall produced by the storms, can result in more destructive storm surges and flooding.
