Weather is Making Allergy Season Worse

Weather is Making Allergy Season Worse

Climate Change and Pollen Allergies

  • Pre-1990s: Allergy seasons and pollen levels are within historical norms.
  • 1990s: Research indicates that ragweed pollen monitoring has been taking place at 11 locations in the central US and Canada since this decade as part of a national allergy monitoring network.
  • 1990-2018: Research by William Anderegg finds approximately a 21% increase in overall pollen concentrations in North America.
  • Since the Beginning of the 20th Century: The contiguous U.S. has experienced an increase of more than two weeks on average in the frost-free season.
  • Since the 1970s: The frost-free season has expanded by an average of at least 11 days in all nine of the U.S.'s distinct climate regions.
  • 1995: The US EPA begins tracking changes in ragweed pollen season length at 11 locations in the central United States and Canada.
  • 1995-2015: Analysis of ragweed pollen season data shows a lengthening of the season at 10 of the 11 studied locations, with more pronounced increases at higher latitudes. Winnipeg, Manitoba, sees the largest increase at 25 days.
  • 2011: A study estimates the economic impact of medically treating seasonal allergies in the United States to be $3.4 billion annually.
  • 2016: A study in Sweden analyzes the economic impact of allergic rhinitis, estimating an impact of about $1.43 billion in Sweden alone due to presenteeism, absenteeism, and medical treatment.
  • 2018: A study notes only 85 pollen stations operating in the U.S., highlighting a need for more comprehensive monitoring.
  • 2019: The Asthma and Allergy Foundation of America reports that ragweed pollen allergy affects an estimated 15.5 percent of all Americans.
  • 2019: An EPA study estimates that between 35,000 and 60,000 asthma-related emergency department visits were linked to pollen, projecting a potential 14% increase by 2090.
  • Early 2020s (anecdotal): Allergists report an increase in patients seeking treatment for seasonal allergies.
  • 2021: The CDC begins collecting data on the prevalence of seasonal allergies.
  • April 19, 2023: Samantha Harrington publishes an article in Yale Climate Connections highlighting research by William Anderegg and Brooke Lappe on the impact of climate change on worsening pollen allergies.
  • March 18, 2025: Kasha Patel publishes an article in The Washington Post detailing the "allergy capitals" of the U.S. for the previous year (2024), based on data from the Asthma and Allergy Foundation of America. Wichita, Kansas, is ranked the most challenging city.
  • April 9, 2024: Bridget Balch publishes an article in AAMC News discussing how warmer temperatures and "botanical sexism" are exacerbating seasonal allergies.
  • By 2050 (projected): Some computer models suggest that climate change could significantly increase airborne pollen loads, even in areas that currently have low loads.
  • Ongoing: Climate change continues to cause warmer temperatures, longer frost-free seasons, increased carbon dioxide levels, and altered precipitation patterns, all contributing to longer and more severe pollen seasons and worsening allergy symptoms.

Christmas 2024 Travel Briefing: Weather Impacts and White Christmas Predictions

Christmas 2024 Travel Briefing: Weather Impacts and White Christmas Predictions

Christmas 2024 Travel Briefing: Weather Impacts and White Christmas PredictionsThis briefing summarizes key weather information for the Christmas 2024 holiday period, drawing from several weather forecasts and news articles.Main Themes:Unsettled weather leading up to Christmas: Many regions will experience rain, snow, and potentially disruptive weather in the days preceding Christmas.Warmer temperatures for many on Christmas Day: A warming trend is expected across much of the US, bringing above-average temperatures and reducing the likelihood of snow in many areas.Limited White Christmas potential: While higher elevations in the West and areas near the Canadian border have the best chances, widespread snow cover on Christmas morning is unlikely across the contiguous US.Travel disruptions possible: Travelers should anticipate potential delays due to weather, especially in the days leading up to Christmas.

Miami and Tampa: High Risk to Climate Change, Rising Sea Level

Miami and Tampa: High Risk to Climate Change, Rising Sea Level

Meteorology Matters examines Miami and Tampa's vulnerability to hurricanes and climate change. Miami, despite its booming population and development, faces significant climate risks, including rising sea levels and increased flooding, yet many residents remain, prioritizing lifestyle over potential dangers. Tampa, similarly situated in a low-lying area, presents a high-risk scenario due to its rapid growth and the potential for catastrophic storm surge, with the upcoming Hurricane Milton posing an imminent threat. Both cities highlight the complex interplay between economic growth, environmental risks, and individual choices in the face of climate change. Experts express serious concern about the preparedness of both cities for extreme weather events.

Walkable Cities Good for Earth While Americans Prefer Suburbia

Walkable Cities Good for Earth While Americans Prefer Suburbia

Meteorology Matters examines the environmental impact of suburban sprawl, contrasting it with denser, more walkable urban neighborhoods. We explore the trade-offs between walkability, affordability, and living space, highlighting public preference for sprawling suburbs despite their higher carbon footprint. We look at the effects of suburban development on natural habitats, noting both habitat loss and surprising animal adaptations. Finally we examine strategies to reduce the climate footprint of suburban areas, suggesting policy changes, technological upgrades in homes and transportation, and individual actions to mitigate emissions.

Hurricane Helene: Impact Erwin Tennessee

Hurricane Helene: Impact Erwin Tennessee

Meteorology Matters looks at a Washington Post investigation into the deaths of six Impact Plastics employees during Hurricane Helene's flooding in Erwin, Tennessee. The investigation highlights the role of both the severe weather and allegedly inadequate employer responses in the fatalities, contrasting this with the successful rescue of hospital staff and patients. We also examine the deaths of workers at an Amazon warehouse and a Kentucky candle factory during a tornado. The lack of union representation contributed to the workers' inability to leave their workplaces before the disaster and emphasizes the importance of unions in ensuring worker safety and fair treatment. This boils down to the tragic consequences of prioritizing profit over worker safety in the face of extreme weather events.

Gust vs Sustained Wind: Application to Building Standards

Gust vs Sustained Wind: Application to Building Standards

Meteorology Matters presents an analytical framework for standardizing tropical cyclone wind characteristics (mean wind speed, turbulence intensity, integral scale, gust factor, and peak factor) from various measurement conditions to a common reference. This framework uses equilibrium boundary-layer theory and is applied to data from seven tropical cyclones (four typhoons, three hurricanes), comparing results to existing standards (ASCE 7-10 and AIJ-RLB-2004). We continue to. examine gust factor variations based on coastal tower measurements during three landfalling typhoons. We explore the relationships between gust factor and turbulence intensity, height, wind speed, and direction, finding that gust factors are smaller than those in national codes and influenced significantly by shoreline confinement on sea wave development.
