Richmond allergy season is getting longer — and it's worse than ever
Richmond's spring allergy season is incoming — and it's getting longer.
Why it matters: We were once again ranked as one of the worst U.S. metro areas to live in for people with seasonal allergies this year, according to the Asthma and Allergy Foundation of America
The big picture: In the past 50 years, Richmond's allergy season has grown by more than a month (31 days), according to Climate Central.
The research and communications group analyzed the freeze-free season between 1970 and 2024 as a proxy for allergy season.
Better plant growth happens when it's warmer, and warmer temperatures mean more sneeze-inducing pollen.
Plus, "Climate change makes pollen seasons not only longer, but also more intense due to heat-trapping pollution," per Climate Central's report.
"Higher levels of planet-warming CO2 in the air can boost pollen production in plants, particularly in grasses and ragweed."
The bright side: We don't live in Reno, Nevada, where the allergy season has lengthened by 96 days since 1970.
But Norfolk's allergy-sufferers have it best in Virginia. Their allergy season has only grown by eight days.
What's next: Richmond's pollen count is medium-high this week with juniper, birch and sycamore being our predominant pollen, per Pollen.com.

New Orleans hits 110°F heat index and it's just the beginning
This summer has a 50% chance of being hotter than average in New Orleans and most of Louisiana, according to the National Weather Service's Climate Prediction Center. Why it matters: Extreme heat is a major public health threat. It also threatens the reliability of the power grid. The big picture: New Orleans over the weekend had its first heat advisory of the season. New Orleans tied the high temp record on Saturday of 95°F. The "feels like" temp was 110°F at the airport and lakefront, according to the National Weather Service in Slidell. Temperatures are expected to be in the high-80s and low-90s all week, with daily thunderstorms possible, NWS says. The cloud cover should keep the "feels like" temp around 108°F. Yes, but: This is just the start. July and August are historically the hottest months of the year in New Orleans. Threat level: The heat has already been deadly this year. A toddler died Sunday in Hammond after being left in a hot car for more than nine hours, authorities say. Last year, 51 people died in Louisiana from heat-related causes, according to the state health department. How to protect yourself: If you are outside in the heat, drink plenty of water, wear lightweight clothes, apply sunscreen and take frequent breaks in the shade or AC, officials say. Summer's getting hotter Zoom out: Like most of the country, summer has been getting hotter in New Orleans over the past 50 years, a recently updated analysis found. The average summer temperature in New Orleans is now 4°F hotter than it was in 1970, according to Climate Central, a nonprofit climate research and communications group, using NOAA data through 2024. Zoom out: On top of rising overall temperatures, New Orleans is the among the worst " heat island" communities among all major U.S. metros, according to Climate Central. 77% of New Orleanians live in urban heat island neighborhoods, the group says. New Orleans can be more than 8°F warmer than surrounding tree-covered communities, mostly due to a lack of permeable surface. Go deeper. How to cool off Go deeper

Thousands impacted as torrential rains trigger mudslides: 'The impacts are expected to increase'
China's Yunnan province was struck at the start of June by devastating flooding that impacted nearly 5,000 residents and trapped more than 600 tourists. Torrential rains soaked southwestern China during the country's Dragon Boat Festival, a long holiday weekend celebrated this year from May 31 through June 2. The intense rain fell in Yunnan, which borders Vietnam, Laos, and Myanmar. Local authorities had issued a red alert, the highest level of four in China's four-colored warning system, before the deluge arrived. The flooding rains triggered mudslides and destroyed buildings and bridges in the region. Fortunately, no casualties were reported despite 4,800 residents in Gongshan County being impacted by the severe weather. Some popular hiking sites in the mountainous region had their road access cut off during the flooding. An evacuated four-story building on the Dulong River, which reached record levels during the flooding, collapsed, according to state broadcaster CCTV, per Reuters. Our warming world is altering the water cycle. "Climate change is likely causing parts of the water cycle to speed up as warming global temperatures increase the rate of evaporation worldwide. More evaporation is causing more precipitation, on average," according to the University Corporation for Atmospheric Research. "We are already seeing impacts of higher evaporation and precipitation rates, and the impacts are expected to increase over this century as climate warms." Our overheating planet is supercharging storms. Climate Central discovered that many U.S. cities (88% of the 144 analyzed) have experienced an increase in hourly rainfall intensity since 1970. In another study, Climate Central scientists found that our overheating planet increased wind speeds for every Atlantic hurricane last year. Another flooding event made headlines in late May, just a few days prior to the Yunnan event. A storm produced a deadly deluge in New South Wales, Australia, killing at least five people and leaving an estimated 50,000 people stranded. "Climate change is increasing the risk of landslides," according to French geophysicist Gilles Grandjean, per the Paris Polytechnic Institute. Even though the direct role our planet's rising temperatures have on landslides is difficult to pinpoint, "as climate change affects precipitation (by increasing the frequency of extreme events), it also has an impact on the risk of landslides," added Grandjean. Scientists say our warming atmosphere is acting like steroids for our world's weather. Cooling our planet by moving away from dirty energy and adopting renewable options is the best way to counter this effect. New research from scientists in Germany and the United Kingdom has shown how small, hydrogen-powered boats could significantly lower carbon pollution from Europe's transportation sector. Chinese researchers may be close to a major breakthrough that would mark a significant advancement in solid-state batteries, which many say is the "holy grail" for green tech. We can become advocates for the future of our planet by learning about critical climate issues and raising awareness about them through discussions with friends and family. Supporting pro-climate politicians is another way we can help protect our planet. Do you think America is in a housing crisis?

The spring season started off pretty dry across the Carolinas, but we did get into more of a wetter pattern right at the end of the season. Overall, Charlotte ended the meteorological spring season with the 85th wettest spring on record, recording 10.27″ of rainfall. Now we head into meteorological summer, where the Climate Prediction Center is projecting a warmer and wetter than average summer for the Carolinas. Charlotte summers are getting warmer as well, with over two degrees of warming over the last five decades. The Queen City has also added on average almost a month's worth of warmer-than-normal days over the last 50 years according to Climate Central. Copyright 2025 Nexstar Media, Inc. All rights reserved.
