A new study says human-caused climate change made Atlantic hurricanes about 18 mph stronger in the last six years.

The 12 months ending in October were the hottest ever recorded on Earth and likely the planet’s hottest 12-month period ever recorded, according to a report from the nonprofit science research group Climate Central.

Here are the July stats for temperatures in the Roanoke area, according to data from the National Weather Service.

A new quick study finds that human-caused global warming made July hotter for four out of five people on Earth.

And over the last several decades, Detroit’s first 80-degree day of the year has been coming earlier and earlier in the season.

Teaming up with NBC’s Climate Challenge week, Local 4 meteorologist Paul Gross will answer the most-asked questions about climate change all week long.

According to data from Climate Central, across all the Great Lakes the annual maximum ice cover is, on average, 22% lower than it was a half-century ago. Furthermore, ice coverage is becoming less reliable, with more frequent years of extremely low ice coverage. Based upon ice coverage charts from the NOAA Great Lakes Environmental Research Lab in Ann Arbor, ice cover on the five Great Lakes peaked at an average of 47% this winter (with shallow Lake Erie skewing the numbers upward with its 80% ice coverage…the other four Great Lakes all peaked at or below 50% ice cover). This compares to an average ice cover for all five lakes of 53% in the 1973-2020 time period. AdMore information: Great Lakes Ice Coverage is ShrinkingRelated:

DETROIT – The average fall temperatures in Detroit have warmed 3.2 degrees (F) since 1970. Research from scientists at Climate Central shows that every part of the United States has experienced a warmer trend in fall temperatures since 1970.

The solid line shows the warming trend. Fall warming in Detroit sine 1970 (Climate Central)Climate Central also shows Detroit is experiencing 14 more days with above average fall temperatures.

DETROIT Scientists at at Climate Central counted the hot summer days in Detroit from 1970 to today. This revealed a trend in the increase of hotter than normal, or above average, summer days in Detroit. With climate change, a Detroit summer will eventually feel like a Missouri summer of today. This map from Climate Central shows average summer temperature change since 1970 across America:

The number of people threatened by climate change-triggered flooding is about three times higher than previously thought, a new study says. (AP Photo/Apichart Weerawong, File)WASHINGTON, DC The number of people threatened by climate change-triggered flooding is about three times higher than previously thought, a new study says. So instead of 80 million people living in low-lying areas that would flood annually by 2050 as the world warms, this new study finds the population at risk is closer to 300 million people. Space-based radar says 170 million are at risk in that scenario. Five outside sea level rise experts said the study highlighted a problem with current data, especially in Asia.

DETROIT - New research conducted by Climate Central and released this week shows that high heat index days here in Detroit are increasing. And the study found that 198 of those 239 cities experienced an increase in the annual average number of days with heat index temperatures of 90 degrees or hotter. McAllen, Texas tops the list with an increase of 31.6 annual 90 degree heat index days since 1979. Well-known cities in the south also on the top 10 list include New Orleans (23.6 days), Miami (23.0 days), and Savannah (22.8 days). More 90 plus degree heat index days certainly would be a part of that.

The National Weather Service's heat index measures how hot it feels when you factor in relative humidity with the actual air temperature. The South and Southwest see these high heat index days throughout the summer. Miami had 160.6 days extreme heat days on average over the last five years, for example. A "danger" day is when the combined heat and humidity makes it feel like it's 105 degrees Fahrenheit or hotter. For both conditions, "danger" days and "heat index" days, it can be dangerous to exercise outside and can lead to heat exhaustion and heat stroke.
