«Breaking News» British summers could be 9°F hotter by 2070 sparking more wildfires and water shortages

Britain could bake in regular 40C (104F) heatwaves as a result of global warming, the Met Office warned in a major report yesterday.

By 2070, average summer temperatures could reach 24C (75F) – an increase of 5.4C on today.

This is similar to conditions in the south of France and other parts of the Mediterranean, with hot UK summers like this year's becoming the norm.

The climate will be drier too – with half as much rainfall in summer as now within 50 years, although winters could be around 35 per cent wetter. 

There are fears such extremes would lead to increased flooding in winter as well as arid heat and droughts in summer.

And those who live in areas where there is a high risk of severe flooding may have to be moved away, the government has warned.

The record-breaking heatwave conditions experienced across the globe this summer could 'become the norm' if steps aren't taken to tackle global warming. The red patches denote areas in which temperatures were up to 39F higher than is normal for that time of the year

The forecasts are made in the Met Office's UK Climate Projections 2018 (UKCP18) report, which is the biggest update to how climate change could affect Britain in almost a decade. They would only happen, the study said, if the world continues to increase carbon emissions rather than reduce them, which is most countries' policy.

The record UK temperature is 38.5C (101F), set in 2003 near Faversham in Kent.

But Professor Jason Lowe of the Met Office warned: 'As we go through the century, we expect from UKCP18 to see increasing numbers of summer days in the South of England above 40C. This is a temperature we have not yet experienced in the UK.'

Winters will be around 4.2C warmer while sea levels will rise around one metre higher (3.2ft) if the effects of global warming cannot be prevented.

Summers as hot as this year's – the joint warmest on record –could become common, with a 50 per cent chance of occurring every year. This is up from a 5 to 10 per cent chance now.

Sea levels affecting London, where the Thames Barrier is expected to be in use until 2070, could rise by up to 3.7ft by 2100 if emissions continue to climb, with similar rises in Cardiff.

Belfast and Edinburgh will see increases of around 3ft under the worst-case scenario.

Even if emissions are cut – in line with the Paris climate agreement to keep temperature rises to well below 2C – the UK's average yearly temperatures would be 2.3C hotter.

Last month the UK's Committee on Climate Change warned that by 2080 up to 1.2million homes may be at increased risk of flooding.

At a speech launching the report at London's Science Museum on Monday, Environment Secretary Michael Gove called for urgent action to tackle climate change. 

'Climate change [in the UK] will manifest itself most acutely when it comes to water – the intense rainfall of the winter, the arid heat of the summer and rising sea levels will be how we experience climate change most immediately.' 

He said officials were already factoring projected sea level rises into planning for flooding, while new reservoirs would be built to tackle drought.

But Mr Gove admitted that it won't always be possible to prevent every flood or reinforce every building. As a result, some may need to relocate.

'We need our communities and infrastructure to be better prepared for floods and coastal change, so that they recover more quickly from the damage and disruption and, where necessary, to help people and communities move out of harm's way,' he said in a speech in front of Department for Environment, Food and Rural Affairs stakeholders, the Guardian reports.

Britain is already investing a record £2.6 billion ($3.3 billion) to protect 300,000 homes from flooding by 2021. 

Mr Gove also said farmers should be paid to tackle climate change and boost productivity, from planting cover crops to protect soil to planting trees on agricultural land, while there will be measures to curb fertiliser emissions. 

He added that there would be strategies to repair peatland, protect and create woodlands, and cut food waste. 

But green campaigners accused the Government of not going far enough.  

Campaigners warned that devastating floods that hit Leeds and York in 2015, as well as wildfires on Saddleworth Moor in Manchester this summer, showed that the impacts of climate change can already be seen in the UK.

They said projects to expand airports and build more roads show the government is not doing enough to limit global warming.

Emi Murphy, climate change campaigner at Friends of the Earth, said: 'The human cost of climate change, both in England and around the world, is already devastating.

'It's the most vulnerable communities paying the highest price, while the UK government fails to commit to the policies needed to avoid climate chaos.

'The Climate Change Act was a truly remarkable political achievement that has driven cuts in UK emissions.

'But dire warnings from scientists demonstrate how further and faster action is essential to prevent complete climate breakdown.

'Instead, with its relentless pursuit of fracking, airport expansion, and road building, our government is failing us on climate change.' 

The report noted that 2008-2017 was on average 0.3C warmer than 1981-2010. The top ten warmest years have all occurred since 1990.  

WHAT CAUSED THE SUMMER 2018 GLOBAL HEATWAVE?

There are several leading theories as to what may be causing the recent global heatwave, according to University of Reading climate scientist Professor Len Shaffrey.

1. Climate Change: Temperatures are increasing globally due to the burning of fossil fuels increasing concentrations of atmospheric carbon dioxide. The global rise in temperatures means that heatwaves are becoming more extreme. The past few years have seen some record-breaking temperatures in Europe, for example the 2015 heatwave and the 2017 ‘Lucifer’ heatwave in Central Europe. Unusually warm summer temperatures have been recorded elsewhere, for example in Canada and Japan, and climate change is very likely to have played a role here as well.

2. North Atlantic Ocean Temperatures: Temperatures over the North Atlantic Ocean can play a role in setting the position of the jet stream, which in turn has a profound impact on the weather we experience in the UK and Ireland. This summer has seen relatively warm North Atlantic Ocean temperatures in the subtropics and cold ocean temperatures to the south of Greenland. These are thought to be influencing the high pressure over Europe and pushing the jet stream further northwards.

3. La Nina: Every few years, ocean temperatures in the Tropical Pacific swing between being relatively warm (known as El Nino) and cool (La Nina). Since October last year the Tropical Pacific has been in a La Nina phase. La Nina is sometimes associated with cold winters in North Western Europe (for example the winter of 2010/11 and the recent cold spell in March 2018). However, this year’s La Nina had started to weaken around April and had almost gone by June when the current dry spell in the UK began.

4. It’s the weather: The above factors influence type of the weather get in the UK and Ireland but good or bad luck also plays a role, especially for very unusual weather such as the current hot and dry spell. This summer is no different and the hot and dry weather is partly due a combination of North Atlantic Ocean temperatures, climate change and the weather. Should weather patterns continue as they are then we might expect this summer will turn out to be as hot and dry as the extreme summer of 1976.

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.

Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
