2024: HOTTEST Year on Record Exceeds 1.5°C Threshold

2024: HOTTEST Year on Record Exceeds 1.5°C Threshold

2024: A Year of Record-Breaking Heat and Climate Impacts

The overarching theme is clear: 2024 was the hottest year on record globally, exceeding the 1.5°C warming threshold outlined in the Paris Agreement for the first time and bringing a cascade of extreme weather events

  • Record-breaking Temperatures: 2024 was the hottest year on record globally, surpassing 2023's record. Global temperatures were 1.6°C warmer than the pre-industrial level (1850-1900) according to Copernicus Climate Change Service (C3S), and 2.3°F warmer than NASA's 20th-century baseline (1951-1980) according to NASA's analysis. (Copernicus, NASA, UN, NPR, Al Jazeera)
  • 1.5°C Threshold Exceeded: The global average temperature exceeded the 1.5°C warming threshold set by the Paris Agreement for the first time, although exceeding it in a single year does not mean the agreement has been breached. (Copernicus)
  • Record Warmth Throughout the Year: Every month from January to June 2024 was warmer than the corresponding month in any previous year. July and August saw the hottest day and summer on record, respectively. (Copernicus, Al Jazeera)
  • Warmest Decade on Record: The past 10 years
  • Human Activities Driving Warming: Scientists attribute the warming trend to the release of heat-trapping greenhouse gases like carbon dioxide and methane from human activities, primarily the burning of fossil fuels. (NASA)
  • Climate Change Impacts contributed to extreme weather events across the globe, including:
  • Heat Waves: Extreme heat events were widespread, with many regions experiencing "strong" or even "extreme" heat stress.
  • Floods: Heavy rainfall events caused widespread flooding, such as in Nigeria, Europe, and Australia.
  • Wildfires: Prolonged dry conditions fueled devastating wildfires in Canada, South America, and other regions.
  • Hurricanes: Warmer ocean temperatures intensified hurricane activity, with Hurricane Beryl in the Atlantic becoming the earliest Category 5 hurricane on record.
  • El Niño: A strong El Niño event in 2023 Reduced Aerosol Emissions: Changes in shipping regulations led to a reduction in sulfate aerosols in the atmosphere
  • Hunga Tonga-Hunga Ha'apai Volcanic Eruption: The 2022 volcanic eruption injected water vapor into the atmosphere

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.
