Here’s How Hot Conroe And Montgomery County May Get By 2050

CONROE, TX — Everyone in Conroe and Montgomery County all know just how hot it can get during the summer months. However, a new report shows the dire reality many communities face in the future due to extreme temperatures driven by human-caused climate change.

Few areas will not be impacted by extreme heat by midcentury, according to the report released Tuesday by the Union of Concerned Scientists, a nonprofit advocacy group based in Cambridge, Massachusetts.

Historically, Conroe and Montgomery County averages about 118 days per year where the heat index reaches at least 90 degrees. That means that while the thermometer might show a lower temperature, the temperature feels like at least 90 degrees. For heat indices of at least 100 and 105, Conroe and most of Montgomery County typically sees 13 days per year.

Here are the number of high heat index days Conroe and Montgomery County can look forward to down the road, given three different scenarios: slow response to curbing climate change, no response and rapid response.

Midcentury
Slow action
90 degree days: 152
100 degree days: 99
105 degree days: 65
Off the charts days: 3
No action
90 degree days: 157
100 degree days: 110
105 degree days: 79
Off the charts days: 6
Late century
Slow action
90 degree days: 159
100 degree days: 107
105 degree days: 74
Off the charts days: 4
No action
90 degree days: 179
100 degree days: 141
105 degree days: 118
Off the charts days: 24
Rapid action:
90 degree days: 154
100 degree days: 100
105 degree days: 65
Off the charts days: 3

Should the globe take no action to reduce emissions, the average number of days across the country that feel warmer than 100 degrees will more than double to about 36 by midcentury, the organization found. By the end of the century, that number would increase to 54.

Kristina Dahl, senior climate scientist at the organization and co-author of the report, said the analysis shows a “hotter future that’s hard to imagine.”

"Nearly everywhere, people will experience more days of dangerous heat even in the next few decades," she said in a news release.

If emissions aren’t reduced, parts of Florida and Texas would see at least five months per year with a heat index of at least 100 degrees by the end of the century. Most of these days would exceed 105 degrees, and many would be so extreme, they’d be classified as off the charts — a condition currently only seen in the Sonoran desert on the border of southern California and Arizona.

"Such conditions could pose unprecedented health risks," she said.

Many places are unaccustomed to these levels of extreme heat, such as the upper Midwest, Northeast and Northwest, and the ability of people and infrastructure in these places to cope with the new normal is “woefully inadequate,” said Rachel Licker, senior climate scientist at the organization and report co-author.

The Southeast and Southern Great Plains are expected to bear the brunt of the extreme heat, the authors found, and by late century, residents in these areas “may have to significantly alter ways of life,” she said.

"We don’t know what people would be able and willing to endure, but such heat could certainly drive large-scale relocation of residents toward cooler regions," said Licker.
