Mr. Khan added: ‘The Met Office has now issued a red warning for extreme heat on Monday and Tuesday.
“It is potentially dangerous and a very serious consequence of climate change.
“This warning is not limited to the most vulnerable and means that substantial changes to all our daily routines will be required, and there is likely to be an impact on travel.
‘All major agencies and emergency services in the capital are working closely together to ensure London is prepared for the extreme heat which is forecast and will continue to provide advice to Londoners ahead of Monday.

There’s a 50 per cent chance of temperatures hitting 40C somewhere in the UK, likely along the A1 corridor, with the Met Office issuing its first-ever red warning for extreme heat.

RAC urges motorists to ‘think carefully’ before driving on ‘hottest day in history’
Motorists were warned against driving on Monday and Tuesday as the country braces for the hottest day in recorded history, with the Met Office predicting temperatures of 106F or 41C.
The RAC said it expects a major increase in breakdowns as cars overheat in extreme weather conditions.
Drivers are advised if they must use their car that they should ensure that all fluids are at their correct levels and carry an emergency kit in case of breakdown.
Rod Dennis, the RAC’s outage spokesman, said: ‘If temperatures were to reach around 40C as some are predicting, then people would have to question their decision to drive in the first place.
The Met Office’s unprecedented red weather warning says there is an 80 per cent chance temperatures will beat the current record of 101.7F set in 2019 in Cambridge.
Level four is reached “when a heat wave is so severe and/or prolonged that its effects extend outside the health and social care system…At this level, illness and death can occur among healthy people, not just in high risk groups,” he said.
The Met Office red warning, for Monday and Tuesday, covers an area from London to Manchester and up to the Vale of York.
Met Office spokesman Grahame Madge said: ‘If people have vulnerable relatives or neighbours, now is the time to ensure they have the appropriate measures in place to be able to cope with the heat , because if the forecast is as we think it will be in the red alert zone, people’s lives are in danger.
“It’s a very serious situation.”
He said there was an 80 per cent chance that Britain’s all-time temperature record would be broken and a 50 per cent chance that temperatures of 40C would be reached somewhere in the UK.
“It would most likely be in the red warning zone for extreme heat,” Mr Madge said.
“The most likely areas to be looked at would probably be north of London and up to Lincolnshire inland.
“Somewhere like Peterborough, Grantham, Sandy, Stevenage, those kind of areas, corridor A1.”
He said temperatures reaching 40C would be a “historic event”.
“If we get to 40C, that’s a very iconic threshold and it shows that climate change is with us now,” he said.
“That is made much more likely due to climate change.”
Mike Childs, Head of Science, Policy and Research at Friends of the Earth, said: “Every year the effects of climate breakdown are becoming more evident and more severe.
“Without significant government intervention, millions of Britons, especially the elderly and young children, will be increasingly exposed to health-threatening heat waves like the one we are experiencing.”
