By the start of the 22nd century simmering summer temperatures will be the norm as will be warmer winters. And this frightening scenario is being caused by, you guessed it, climate change.

In the U.S. for example, Boston's average summer high temperatures will be more than 10°F hotter than they are now. That will make today's glacial Boston as warm as North Miami Beach is today assuming the current emissions trends, said Climate Central.

And the winters in Boston at the start of the 22^nd century will be like the winters in Marietta, Georgia. Boston currently has 115 nights below freezing compared to Marietta's 53 nights.

Climate Central, a nonprofit news organization that analyzes and reports on climate science, affirms the world of the 22nd century will definitely be a warmer place, and will bear all the consequences of that warming.

Is created an interactive map titled "Winter loses its cool" to graphically illustrate how warm winters will be in the next century in the U.S. Click here to go to this interactive map.

Climate Central has also created another interactive map showing how much warmer the world will be in the 21^st century. Click here to go to this "Blistering Future Summers" webpage.

What is frighteningly similar in both the cold and warm scenarios is that climate worldwide is getting hotter.

Climate Central points to the established fact summers in most of the U.S. are already warmer than they were in the 1970s. Climate models are almost unanimous in declaring summers are going to keep getting hotter as greenhouse gas emissions continue.

"What will this warming feel like? Our new analysis of future summers illustrates just how dramatic warming is going to be by the end of this century if current emissions trends continue unabated", said Climate Central on its webpage.

In its Blistering Future Summers interactive, Climate Central projected summer high temperatures for the end of this century for 1,001 cities, and then showed which city in the U.S. and elsewhere in the world is experiencing those temperatures today.

"By the end of this century, summers in most of the 1,001 cities we analyzed will feel like summers now in Texas and Florida (in temperatures only, not humidity). And in Texas, most cities are going to feel like the hottest cities now in the Lone Star State, or will feel more like Phoenix and Gilbert in Arizona, among the hottest summer cities in the U.S. today".

In some cases, summers will warm so dramatically that their best comparison is to cities in the Middle East. Temperature highs in Las Vegas are projected to average a scorching 111°F, which is what summer temperatures are like today in Riyadh, Saudi Arabia. And at 114°F°, living in Phoenix will feel like summering in sweltering Kuwait City.

On average, summer heat is projected to warm 7-10°F, though some cities will have summers 12°F warmer than they are now. This analysis only accounts for daytime summer heat,  the hottest temperatures of the day on average between June to August.

This projected warming also assumes greenhouse gas emissions keep increasing through 2080, just as they've been for the past several decades.

Winters will definitely be warmer and that will be dangerous. Warmer winters "can have negative impacts: ski resorts need freezing temperatures for snow, some crops rely on a chill period, and pests can flourish year-round if winter temperatures aren't cold-enough for them to die off", said Climate Central.

Fewer colder nights will also mean less snow on the ground and less ice forming over water. With less snow and ice, more energy becomes available to go into global warming.
