Cash injection: London Mayor Sadiq Khan

London Mayor Sadiq Khan

London is “unprepared” to deal with the consequences of climate change, a leading thinktank has warned, as Mayor Sadiq Khan says the capital must “adapt”.

Commuters were warned to only travel if necessary on Monday and Tuesday amid record-high temperatures, with heat-related issues disrupting the city’s transport network.

Temperatures on Tuesday exceeded 40C, making it the hottest day in the UK’s history.

The extreme weather comes almost exactly a year on from devastating floods that damaged thousands of homes, engulfed Tube stations, and led to hospitals being closed. A month’s worth of rain fell in one hour.

Nick Bowes, chief executive of the Centre for London thinktank, said that the extreme weather shows “just how unprepared the city is for the effects of climate change”.

He said: “Experts predicted that 40C would be seen at some point in the future in the UK, but not as soon as 2022. As a result, the race to net-zero has just become all the more critical.

“There’s no point beating about the bush – heat of this kind is a killer. That’s why, with more of this expected in future years, London is going to need to redouble efforts to reduce emissions and adapt to the worst impacts of climate change on the city’s homes, workplaces, public transport and urban realm.”

Speaking on Monday, Sadiq Khan told the LDRS it is “really important” to explain that such extreme weather events are “a direct consequence of climate change”.

The London Mayor said it is essential to “tackle the root causes of climate change”, including by achieving net-zero, but that it is also crucial to “deal with the symptoms and adapt our city”.

He added: “The good news is, the new stuff we’ve been building – the Elizabeth Line, new buildings, because of our London plan – they’re cooler in the summer and warmer in the winter. They’re energy efficient, have [lower] bills. But the older stuff: the old homes, the old places of work, the old public transport are not.”

Khan said that places of work must be made to be as cool as possible, while efforts must be made to plant more trees to provide shade across the capital.

He also repeated calls for the government to agree a long-term funding deal for Transport for London so that more electric buses could be purchased – these have cooling systems on board and “emit far less carbon”.

Khan went on to take a swipe at the candidates running to be the next leader of the Conservative Party, accusing them of treating climate change “as an afterthought, if at all”.

He said: “Although many of us who are reasonable and like to look at the evidence would accept this [weather] is based on climate change, there are many who don’t believe that.”

The Tory leadership contest has so far seen little mention of the climate emergency, and a recent YouGov poll found that it was the lowest priority for members of the party who will vote for the next leader.

The survey, commissioned by The Times, found that issues such as winning a general election and cutting taxes were all more important to members of the party, with just four per cent saying that reaching net-zero targets was one of their top three priorities.
