Hot Degrees For The Future – The climate in Barcelona (right) is not always a good thing – the city suffered a severe drought in 2008.
London could be as hot as Barcelona by 2050, with the climate in Edinburgh hotter than Paris, Leeds hotter than Melbourne and Cardiff hotter than Montevideo.

Hot Degrees For The Future
This is from a study which examined how a 2C rise in temperature could change 520 of the world’s major cities.
Heat Alert: Hot Conditions Continue Into Weekend
More than a fifth, including Singapore and Kuala Lumpur, will experience conditions the likes of which no major cities have seen before, Crowther Lab says.
London could suffer the kind of extreme drought that hit Barcelona in 2008 – when it was forced to import drinking water from France at a cost of £20m.
A rise of 2C by 2050 today compares to temperatures in the “pre-industrial era” – usually considered to be between 1850 and 1900 – when the burning of fossil fuels had not yet changed the climate.
The increase in temperature would result in the average UK temperature during the hottest summer rising by around six degrees to 27C.

Scientists hope that pairing the cities will help people visualize the impact climate change could have on their lives.
“History has repeatedly shown us that data and facts alone do not inspire people to change their beliefs or actions,” said lead author Jean-Francois Bastin.
The study, published in the journal PLOS One, suggests that Europe’s summers and winters will become warmer, with an average increase of 3.5C and 4.7C respectively.
This is the equivalent of a city moving 620 miles (1,000 km) south – with the furthest from the equator most affected.
How Hot Will Climate Change Make The Earth By The Year 2100?
The Intergovernmental Panel on Climate Change (IPCC) says global temperatures are already 1C higher than pre-industrial levels.
And at the current rate of warming – 0.2C per decade – global warming will reach 1.5C between 2030 and 2052.
People say Melbourne can experience four seasons in one day – something people in Leeds might be used to
The UN The body warned that warming above 1.5C would push us into a “very uncertain world” – adding that “current global commitments are not enough to prevent temperature rise above 2C, let alone 1.5C”.
When Will Climate Change Make The Earth Too Hot For Humans?
Under current national commitments, average temperature increases are estimated to range from 2.9C to 3.4C by 2100.
To keep us below 1.5C, the panel says carbon emissions must be reduced by 45% by 2030 and reach net zero by 2050.
So the projections of this study are actually quite optimistic, imagining a future where measures have been taken to reduce greenhouse gas emissions.
The report predicts that three quarters of the world’s largest cities will experience dramatic climate change under these conditions.

“This study helps to put climate change in the context of human experience – and more importantly, it shows that many places will see entirely new climates that are outside of current human experience,” said Professor Richard Betts, from the Met Office Hadley. Center. Who commented on the study.

“Bringing the climate from Barcelona to London sounds like it could be a good thing – if you don’t suffer from asthma or heart disease, except that London clay shrinks and is brittle if too dry, then swells and expands when very wet.”
Europe has already experienced extremes this summer, with two months worth of rain in one day in some parts of the UK, followed by a heat wave five times more likely due to climate change.
A Billion Degrees Of Separation
Professor Gabi Hegerl of the University of Edinburgh said the study “cannot account for individual events such as unprecedented heat waves, droughts and heavy rain or floods”.
It’s not good news – but it’s important not to feel overwhelmed by the scale of the climate crisis.
And if you’re feeling a little worried about the future, here are some tips on how to be a little more eco-friendly in your everyday life. Climate change is raising summer temperatures across the country. We often talk about warming in terms of average temperatures, which may be perceived as low by the public, but every increase in average temperature leads to an increase in the number of days that are extremely hot.
To understand what’s going on, we have to get a little crazy and take you back to your statistics class. The classic bell curve represents the distribution of all temperatures in that location. Most of the temperatures – those near the average – are near the middle of the curve. Record temperatures, which are rare, sit on the edges, with hot on the right and cold on the left. When the world warms due to increased greenhouse gases, the entire curve shifts to the warmer side, to the right. The shift results in a large jump in the number of extremely warm days and a decrease in extremely cold days. It also means that heat records are more likely to be set than cold ones. And precisely the extremes affect our lives.
Heat Waves And Climate Change
This is what we see in most of the country. The average summer temperature rose several degrees across the Western and Southern Plains, leading to more days above 100°F in Austin, Dallas and El Paso, all the way to Oklahoma City, Salt Lake City and Boise. It is worth noting that this trend is seen throughout the Northern Hemisphere, as shown in this animation.
The increase in extreme heat has repercussions for health, agriculture and the energy grid we rely on to stay cool in the summer. More extreme heat increases the risk of heat-related illnesses, such as heat exhaustion, and allows insects to move to new areas, potentially increasing the spread of vector-borne diseases. It stresses crops accustomed to milder climates and can intensify drought. Extreme heat is also associated with stagnant air, which traps pollutants and can worsen respiratory diseases such as asthma. The extra heat increases the demand for air conditioning, raising cooling costs and stressing the power grid. Just look at Alaska, which broke an all-time heat record in July, reaching 90 degrees Fahrenheit. Dozens of other cities are in the grip of a heat wave this week, which forecasters have warned will be “prolonged, dangerous and potentially deadly”.
But how much will temperatures in American cities change by 2050? By then, scientists say average global warming from pre-industrial levels could be roughly twice as much as in 2018 — and much more obvious and disruptive. That’s the world you will (probably) live in. And it’s one that we definitely pass on to the next generation.
Here’s how winters and summers in the city nearest you are predicted to change in about 30 years. (More about our methodology here.)
Not As Hot, But Daily Rain And Storm Chances Return
Winters and summers will be warmer in every city by 2050. Enter other cities to see for yourself:
Our analysis, first published in October 2018, shows that in almost every case, the places we live will be noticeably warmer in a few decades.
Every season in every city and town in America will change, subtly or drastically, as average temperatures rise, along with highs and lows. Some of those changes—like summers in the Southwest that warm by 4°F on average—will mean days where it’s so hot it’s dangerous to go outside. Heat waves across the country can last up to a month.
Winters will lose days in the 20s and 30s. Rain and snow storms will be more intense and frequent in some places, and less predictable and milder in others.

So much of a city’s culture and economy depends on the details of the local climate. How high will summer electric bills be in Frederick, Maryland when it’s as hot as Tulsa, Oklahoma today? What happens to tourism in New Hampshire if there is little snow for skiing? Where will Phoenix, Arizona get its water when the Colorado River slows to a trickle? When will the threat of devastating hurricanes make life on the Gulf Coast too risky?
For those who cannot afford to move to cool off the heat or find work when local agriculture dries up and fisheries die, the changes will be devastating.
See what the weather (and precipitation) in some northern cities will look and feel like today on the map below. In some cities, it will be like moving two states south.
You might think that an average increase of a few degrees to your summer and winter weather is not so bad.
Days Above 100°f: Projections
But buried in the averages are extreme weather events – heat waves, heavy rainstorms and droughts – which will be far more damaging and dangerous than smaller shifts in the average.
In California, for example, average temperature changes will be more subtle. But new climate models show that there will be more frequent changes from periods of intense rain to extreme drought, a phenomenon known as weather shocks. This will further strain dams and farmers and is likely to lead to more serious landslides.
Therefore, we have selected 10 cities whose winters and summers will be the most warm and
