Storms, fires, heat waves: Year's disasters linked to climate change

Storms, fires, heat waves: Year's disasters linked to climate change

Science
Dec. 31 (UPI) -- Many climate scientists have been reluctant to directly attribute natural disasters and extreme weather events to global warming. But 2018 forced their hand. Increasingly, climate scientists are making the connection between climate change and record-setting weather events -- storms, droughts, floods, fires, heat waves, cold spells and more. New statistical analysis methods and increasingly accurate climate models have allowed climate scientists to more confidently quantify the culpability of rising CO2 levels each time disaster strikes. In 2018, disaster struck often. Storms The hurricane season produced several larger storms and a few odd ones. Hurricane Florence defied trajectory predictions, steering farther north than any previous storm on its route to the East Coas...
Miami Heat start homestand vs. Toronto Raptors

Miami Heat start homestand vs. Toronto Raptors

Sports
The Miami Heat, who own the NBA's longest active win streak at five games, will start a three-game homestand on Wednesday against the Toronto Raptors. Miami (16-16) is also tied for the league lead with a 9-3 win over the past 12 games. And, in the past five games, no Heat opponent has shot better than 42.2 percent from the floor. "For the past two or three weeks, we've had a good flow," Heat forward Justise Winslow said. "Guys are getting comfortable. I like where we are as a team." Meanwhile, Toronto (25-10) has the best record in the Eastern Conference. However, the Raptors are just 5-6 in their past 11 games. Raptors coach Nick Nurse admitted he was a little disappointed his team was once again not invited to play on Christmas Day. "It's a marquee day to play," Nurse said. "I th...
Global warming increases risk of heat stress for outdoor workers

Global warming increases risk of heat stress for outdoor workers

Science
Oct. 8 (UPI) -- Every year, a few hundred people in the United States die as a result of heat exposure, making heat stress the leading cause of weather-related deaths -- deadlier than lightning, tornadoes, hurricanes and floods. Outdoor workers are especially vulnerable to heat, and their risk of exposure to heat stress conditions is likely to increase as the effects of climate change progress. That's why several advocacy groups, including Public Citizen and the United Farm Workers, have petitioned the federal government to establish stronger -- and specific -- heat stress-related protections for outdoor workers. Heat stress conditions are produced by the combination of high temperatures and high humidity. When it's humid, sweat can't evaporate efficiently, limiting the body's natural abi...
'Urban island' heat tests Phoenix, other large cities

'Urban island' heat tests Phoenix, other large cities

Technology
When temperatures soar as they have this week in downtown Phoenix, homeless people ride the air-conditioned light rail to avoid a heat so brutal it killed 155 people in the city and surrounding areas last year. An occasional siren wails as paramedics rush to help people sick from the heat. Already devilishly hot for being in the Sonoran desert, Arizona's largest city is also an "urban heat island," a phenomenon that pushes up temperatures in areas covered in heat-retaining asphalt and concrete. Phoenix on Wednesday recorded a sweltering 116 degrees (46 Celsius), setting a new high for the date. Phoenix officials say they are tackling urban warming, monitoring downtown temperatures, planting thousands of trees and capturing rainwater to cool off public spaces. Elsewhere, Chicago maintains...
Engineers install heat shield on NASA's Parker Probe

Engineers install heat shield on NASA's Parker Probe

Science
July 6 (UPI) -- For the first time in months, the Parker Solar probe is fully integrated. Engineers have reinstalled the spacecraft's next-generation heat shield, NASA announced this week. For NASA's Parker Solar Probe, a spacecraft tasked with studying the sun, protection from extreme heat is obviously essential. The Thermal Protection System will provide that essential shielding. The protective layer was installed last fall but was removed shortly afterwards. In the months since, the shield and spacecraft have been subjected to a series of intensive tests. On its mission to study the sun's corona, the probe will fly within 4 million miles of the sun. The outside of the heat shield will reach 2,500 degrees Fahrenheit, but its insides, instruments included, will never get hotter than 85 ...
