Midsummer heat and high humidity aren't just uncomfortable -- they're a combo that can cause serious illness and even death.
"Whenever you walk or do outdoor activity, take a friend with you who can help you if you run into trouble," Dr. Eleanor Dunham advised. She's an emergency medicine doctor at Penn State Health Milton S. Hershey Medical Center in Hershey, Pa.
Extreme heat strikes poor and minority neighborhoods in U.S. cities harder than those that are wealthier and mainly white, a new study finds.
"The distribution of excess urban heat varies within cities, and as a result, communities do not share a city's extreme heat burden equally," said study co-author Jennifer Burney. She's chair of global climate policy and research at the University o...
Climate change has already become deadly enough to cause 5 million extra deaths worldwide each year, researchers report.
"This is the first study to get a global overview of mortality due to non-optimal temperature conditions between 2000 and 2019, the hottest period since the pre-industrial era," said study co-leader Yuming Guo, a professor at Monash University in Australia.
Could trees be the key to a cool summer in the city?
Yes, claims new research that calculated just how much greenery can bring temperatures down.
"We've long known that the shade of trees and buildings can provide cooling," said study co-author Jean-Michel Guldmann. He is a professor emeritus of city and regional planning at Ohio State University, in Columbus.
Human-caused global warming is responsible for more than one-third of heat-related deaths worldwide, but the proportion is much higher in certain countries, a new study finds.
Researchers analyzed data gathered between 1991 and 2018 from 732 locations in 43 countries. They concluded that 37% of all heat-related deaths in recent summer periods were attributable to the warming of the planet...
As you head into the great outdoors this summer, keep safety in mind, an expert says.
Drowning is one of summer's risks. It only takes a few seconds and can happen without an obvious struggle, according to Dr. Seth Hawkins, a wilderness medicine expert and assistant professor of emergency medicine at Wake Forest Baptist Health in Winston-Salem, N.C.
Rising temperatures caused by climate change could trigger a worldwide increase in stillbirths, researchers warn.
The team at the University of Queensland in Australia analyzed 12 studies on the subject. They found that exposure to extremely high temperatures throughout pregnancy appeared to increase risk of stillbirth, particularly late in pregnancy.
The Middle East and North Africa are already among the hottest spots on the planet, but new research warns that if nothing is done to slow climate change there will be life-threatening heat waves with temperatures of 132 Fahrenheit or higher in those regions.
"Our results for a business-as-usual pathway indicate that, especially in the second half of this century, unprecedented super- an...
Limiting global warming to targets proposed in the Paris Agreement could keep tropical regions from reaching temperatures that are beyond human tolerability, a new study projects.
Researchers estimate that if countries are able to cap warming at 1.5 degrees Celsius above pre-industrial levels, the tropics will be spared temperatures that surpass the "survival limit." But life in the worl...
Some of the leading hotspots in the United States are on track to become even more sweltering in the coming decades -- thanks to a combination of greenhouse gas emissions, urban development and population growth.
In a new study, researchers estimate that over the course of this century, the biggest relative increases in extreme heat will hit cities in the Sunbelt -- including Atlanta;...
With much of the United States blanketed by a heat wave this week, the American Red Cross offers some survival tips.
Each year, extreme heat kills more than 600 people in the United States. And many others are at risk of heat-related illness, especially adults aged 65 and older and those with chronic medical conditions, the Red Cross noted in a news release.
Heat is an underestimated killer in the United States, a new study suggests.
According to researchers, death records indicate that heat kills as many as 600 hundred Americans each year, but moderate heat may actually be killing more than 5,000 annually. And the social distancing restrictions of COVID-19 might make staying cool harder this summer.
Can working or playing in the hot sun "fry" your brain?
Yes, claims a new, small study that found too much heat on the head hampered thinking in volunteers.
Most people know that high temperatures can cause heat exhaustion or heat stroke as the body's core temperature becomes dangerously high, but the beating sun can affect your brain even if your body temperature stays norm...
As summer temperatures soar, dogs are at risk of potentially fatal heat-related illness -- and certain ones appear particularly vulnerable, a large new study confirms.
The study, of more than 900,000 dogs, found that older pooches and those who carried extra pounds were at increased risk. The same was true of certain breeds -- often dogs with "flat" faces, such as bulldogs and pugs.
Researchers have predicted that if climate change goes unabated, the planet will experience intolerable heat in several decades. But a new study has found that in certain global hot spots, it's already happening.
In recent years, certain regions -- including the Persian Gulf, Indian subcontinent and some Mexican locales -- have recorded off-the-charts combinations of heat and humidity...
Dangerously hot days for crop pickers in the United States will double over the next three decades because of climate change, a new study warns.
"Studies of climate change and agriculture have traditionally focused on crop yield projections, especially staple crops like corn and wheat," lead author Michelle Tigchelaar, a postdoctoral researcher at Stanford University who conducted the...
Heart disease deaths spike with extreme heat, and rising temperatures due to climate change may lead to a surge in such deaths in hot regions, researchers say.
For the study, the investigators analyzed 2010 to 2016 data on more than 15,000 heart-related deaths among people aged 15 and older in Kuwait, which has an average temperature of 82.2 degrees Fahrenheit (F).
As the days heat up, people tend to report more emotional distress, a new study finds, adding to concerns that global warming could take a growing mental health toll.
The study of more than 3 million Americans found that the longer people had to sweat out 80-degree days, the bigger the mental health drain. They were more likely to report problems with depression, stress and emotional ...
If climate change continues unabated, the United States should prepare for an increase in deaths from injuries, a new study claims.
Looking at data on injury deaths and temperature over 38 years, researchers found a correlation between unusually high temperatures and increased rates of death from a range of causes -- traffic accidents, drownings, assault and suicide.
Heat waves can pose a serious risk to people with Alzheimer's disease, so their families should know how to keep them safe, advocates say.
Extreme heat is "dangerous for everyone, but especially for someone with Alzheimer's disease, who may be unable to spot the warning signs of trouble or know how to get help," said Charles Fuschillo Jr., president and CEO of the Alzheimer's Foundati...
Across two-thirds of the United States, over 115 million Americans live where some level of heat alert is already in effect, and 290 million will see temperatures soar past 90 degrees at some point in the next week, USA Today reported Wednesday.
As a dome of high pressure settles over much of the eastern and mid-Atlantic states, the heat indexes (the r...
A new analysis suggests the Trump administration should have considered how unchecked climate change might harm U.S. citizens before it pulled out of a pact aimed at slowing down the pace of global warming.
In the study, researchers calculated that tens of thousands of lives in major U.S. cities would be saved annually if rising temperatures were curtailed.
