Summer in the US could be eight degrees hotter in 2100

US cities could get an average of eight degrees hotter by 2100. In about 78 years, 247 US cities could feel like an entire part of the country — or the world — found researchers at Climate Central, a nonprofit organization that studies climate change.

The independent group of scientists and communicators analyzed climate change and how it will affect people’s lives. They found that 16 US cities could have summer temperatures equal to those in the Middle East by 2100. Other cities could see temperatures reflecting locations 437 miles south of them.

Chicago is expected to warm up 9.1 degrees Fahrenheit and feel more like Montgomery, Alabama.

New York is forecast to warm by 7.6 degrees, with summers expected to feel more like Columbia, South Carolina.

Houston is expected to warm up 6.4 degrees and feel like Pakistan’s Lahore, while Phoenix could rise 7.2 degrees and feel like Saudi Arabia’s Al Mubarraz.

Mitchell, South Dakota is forecast to warm the most — by 11.1 degrees — and is expected to feel more like Wichita Falls, Texas.

The hottest average temperatures of the summer days were analyzed. The researchers didn’t account for humidity, which contributes to how uncomfortable summer heat can feel.

“The Earth is warming because the greenhouse gases that we’ve emitted primarily from burning fossil fuels are building up in our atmosphere and acting like a blanket, trapping heat,” Climate Central spokesman Peter Girard said via email to CBS News. “The blanket gets denser and traps more heat the more we soil it, which is why summer temperatures have risen in cities across the US. And they’ll keep going up until we stop adding more pollution to that heat-retaining blanket. “

Extreme heat and prolonged heat waves can lead to illness or death, says Climate Central. With less nighttime cooling due to climate change, vulnerable individuals, the elderly, outdoor workers and those with chronic illnesses may experience more heat stress.

“The summer heat affects health. Working outside, exercising and exercising or living without air conditioning will not only be uncomfortable but also dangerous,” Girard said. “Millions of Americans are already adjusting their lives to avoid the midday heat, and millions more are struggling to stay safely cool. These realities are becoming more common as summer temperatures rise.”

Extreme heat can lead to a higher risk of heatstroke, and extreme heat worsens air quality — especially in cities, Girard added

But climate change does not only affect health. According to Climate Central, it can worsen air quality and pollution, lead to more wildfires, floods and rising sea levels, and worsen allergies, among other things. It can also impact mental health, as the warming climate can lead to even more catastrophic weather events that are difficult to physically and mentally recover from.

Solutions to climate change can also have a positive impact on human health. Climate Central suggests planting trees that lower carbon dioxide and purify the air, and driving an electric car that reduces emissions and improves air quality; and composting, which also lowers carbon dioxide and improves soil and plant health.

Girard says as long as pollution builds up in our atmosphere, temperatures will continue to rise. But climate change is more than just excess heat.

“This analysis did not examine other impacts of climate change, but increased rainfall is another impact American cities are already seeing,” he said. “Because a warming atmosphere can hold more moisture, many places are experiencing heavier rainfall — and a higher risk of flash floods — than they did 50 years ago.”

And for most Americans, so does winter warming. “That hurts winter sports and the local economy, but warming winters also disrupt the growing season and put stress on some crops – particularly fruit trees – and widen the range of common allergens and pests like mosquitoes and ticks,” he said.

Cities in the US and Europe have experienced several heat waves this summer. In July, some US cities saw triple digit temperatures and warnings of increased fire conditions and heat sickness. The same month Britain recorded its first temperature above the 40 degree Celsius mark (104 degrees Fahrenheit).

On Wednesday, CBS Boston weather forecaster and senior weather producer Terry Eliasen said more extreme heat was expected in the area just over a week after it experienced a seven-day heat wave.
