State of the Climate - 2024 and Beyond

2024 is confirmed as the hottest year on record, surpassing 2023, and marking a decade of unprecedented heat. This has triggered extreme weather events globally and heightened concerns about the potential for earlier-than-expected breaches of the Paris Agreement's 1.5°C warming threshold. Scientists are investigating factors beyond fossil fuel emissions and El Niño, such as aerosol reductions from shipping regulations and decreased cloud cover, to fully explain the surge in temperatures. While international agreements and initiatives are in place, urgent and accelerated climate action is imperative to mitigate future warming and adapt to its impacts.

Key Themes and Ideas:

  1. Record-Breaking Temperatures:
  • 2024 is set to be the warmest year on record, continuing a trend of escalating temperatures: "The year 2024 is set to be the warmest on record, capping a decade of unprecedented heat fuelled by human activities." (UN News)
  • The past decade has seen the warmest years on record. "The past 10 years have been the warmest 10 years since record-keeping began." (NPR)
  • Average global temperatures exceeded 1.5°C above pre-industrial levels. (Al Jazeera)
  • Earth experienced its warmest day ever on July 22, 2024. (Al Jazeera)
  • January 2024 was the warmest January on record, with an average surface air temperature of 13.14˚C. (Al Jazeera)
  1. Exceedance of Paris Agreement Thresholds:
  • There is growing concern that long-term warming may exceed the Paris Agreement's 1.5°C limit sooner than expected. "Recent warming has sparked debate about whether the world might exceed the 1.5 °C Paris Agreement limit earlier than previously estimated." (Twelve months at 1.5 °C signals earlier than expected breach of Paris Agreement threshold)
  • Twelve consecutive months with temperatures at least 1.5°C above pre-industrial levels raises alarms, although experts note this doesn't automatically mean the long-term goal has been exceeded.
  • Analysis suggests that exceeding 1.5°C for 12 consecutive months indicates the Paris Agreement threshold is likely to have already been crossed. "Hence, in CMIP6 simulations, 12 consecutive months above 1.5 °C indicates that the Paris Agreement threshold is likely to have already been crossed" (Twelve months at 1.5 °C signals earlier than expected breach of Paris Agreement threshold)
  • Even exceeding the threshold in one year doesn't signal complete failure. Temperatures need to breach 1.5 degrees Celsius consistently, calculated over a 20-year average. "Passing that threshold in one year doesn't mean countries have failed, however. Temperatures would need to consistently breach 1.5 degrees Celsius, according to scientists, calculated over a 20-year average." (NPR)
  1. Extreme Weather Events:
  • Rising temperatures are linked to an increase in the frequency and intensity of extreme weather events: "Climate change also intensified 26 of the 29 weather events studied by World Weather Attribution that killed at least 3700 people and displaced millions." (UN News)
  • Examples of extreme events include deadly floods, devastating wildfires, early heatwaves, and catastrophic hurricanes. (Al Jazeera)
  • Europe could see millions of deaths from extreme heat by the end of the century if carbon pollution is not reduced and adaptation measures aren't implemented. "Extreme temperatures — mostly heat — are projected to kill as many as 2.3 million people in Europe by the end of the century unless countries get better at reducing carbon pollution and adapting to hotter conditions, a new study says." (TIME)

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.
