Hottest January on Record Globally but it was Cold in USA

Hottest January on Record Globally but it was Cold in USA

Climate Change - January 2025 Anomalies and Emerging Explanations

January 2025 presented a paradox: while the contiguous United States experienced its coldest January in 37 years, the planet as a whole recorded its warmest January on record, continuing a trend of extreme heat observed over the past two years. This anomaly has intensified concerns among scientists, leading to investigations into potential contributing factors beyond El Niño and decreased aerosol pollution. Emerging research suggests that declining cloud cover, potentially driven by a feedback loop linked to warming temperatures, may be playing a significant role in the accelerating rate of global warming. The implications of these findings, coupled with concerns about the climate's sensitivity to carbon loading and the potential for exceeding established warming targets, are prompting consideration of controversial solutions like Solar Radiation Modification (SRM).

Main Themes & Key Ideas:

  1. Contrasting Regional and Global Temperatures:
  • The contiguous U.S. experienced a notably cold January 2025. According to NOAA, it was "the Lower 48's chilliest January since 1988... 0.89 degrees Fahrenheit colder than the 20th century January average." Some cities in the Southeast experienced their top 10 coldest Januaries.
  • Despite this regional cold, globally, January 2025 was the warmest on record, surpassing the previous record set just one year prior. According to the European Copernicus Climate Change Service (C3S), January 2025 was the planet's warmest January.
  • This occurred despite a weak La Niña, which typically has a cooling effect on global temperatures. "Perhaps what was so stunning about this was it happened during a weak La Niña."
  1. Acceleration of Global Warming and Scientific Concern:
  • The record-setting temperatures represent a continuation of a trend observed since June 2023, leading scientists to express concern and even alarm. "The world set another monthly heat record in January. That may sound like something we’ve heard a lot lately, but this latest record has scientists mysti ed, surprised and even 'terri ed.'"
  • The consistency of record heat is described as "anomalous even by the standards of the last two years." Some scientists use adjectives like "surprising," "unexpected" or "anomalous."
  • James Hansen's research indicates an underestimated pace of global warming, accelerating by more than 50% in the last few years. The team expects that 1.5°C is now pretty much the climate’s baseline.
  1. Cloud Cover and Planetary Albedo:
  • Two new studies suggest that declining cloud cover contributes to the acceleration of global warming. The Washington Post reports: "Two new studies offer a potential explanation: fewer clouds. And the decline in cloud cover, researchers say, could signal the start of a feedback loop that leads to more warming."
  • Reduced low-altitude cloud cover has decreased the Earth's reflectivity (albedo). "They found that low-altitude cloud cover has fallen dramatically — which has also reduced the reflectivity of the planet. The year 2023 — which was 1.48 degrees Celsius above the preindustrial average — had the lowest albedo since 1940."
  • One study estimates that decreased albedo contributed 0.2 degrees Celsius of warming to 2023's record temperatures. "That low albedo, Goessling and his co-authors calculated, contributed 0.2 degrees Celsius of warming to 2023’s record-high temperatures."

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.
