When Risks Become Reality: 2024 Extreme Weather

Risks Become Reality: 2024 Altered Extreme Weather

This briefing summarizes the key findings of the World Weather Attribution (WWA) report "When Risks Become Reality: Extreme Weather in 2024," analyzing the year's extreme weather events and their connection to climate change.

Key Themes:

  1. Escalating Extreme Weather Events: The report emphasizes the unprecedented levels of extreme weather experienced in 2024, including heatwaves, droughts, wildfires, storms, and floods. These events resulted in thousands of deaths and the displacement of millions. The report states that "Extreme weather reached dangerous new heights in 2024," demonstrating the increasing threat of a 1.3°C warmer world.
  2. Climate Change as a Key Driver: WWA studies directly link climate change to the increased intensity and likelihood of many of these extreme weather events. They analyzed 26 events and found climate change was a significant contributing factor in each, leading to the deaths of at least 3,700 people.
  3. Dangerous Heat Days on the Rise: New analysis by Climate Central, included in the report, shows a global average increase of 41 dangerous heat days in 2024 due to climate change. This poses a severe threat to human health, particularly impacting vulnerable small island and developing states.
  4. Impacts Beyond El Niño: While the El Niño weather pattern influenced early 2024 events, WWA studies consistently found climate change played a more significant role than El Niño in driving events like the historic Amazon drought. This highlights the growing dominance of climate change's influence over natural climate variations.
  5. Record Rainfall and Flooding: 2024 saw record-breaking global temperatures that led to record-breaking rainfall and devastating floods worldwide. Of the 16 flood events studied, 15 were linked to climate change-amplified rainfall. This aligns with the understanding that a warmer atmosphere holds more moisture, resulting in heavier downpours.
  6. Amazon Under Threat: The Amazon rainforest and Pantanal Wetland suffered severe droughts and wildfires in 2024, causing significant biodiversity loss. The report underscores the critical role of the Amazon as a global carbon sink and emphasizes the need to halt deforestation to protect these vital ecosystems.
  7. Intensified Storms: Hotter seas and warmer air contributed to more destructive storms like Hurricane Helene and Typhoon Gaemi. Research points to climate change increasing wind speeds and rainfall in these storms. WWA analysis shows an increasing risk of multiple high-intensity typhoons hitting the Philippines due to climate change.

Conclusion:

The WWA report underscores the undeniable link between human-induced climate change and the intensifying extreme weather events witnessed in 2024. It serves as a stark reminder of the urgency to accelerate global action on climate change mitigation and adaptation to protect lives, ecosystems, and the future of our planet.

Miami King Tides: Flooding this Weekend and Beyond

Miami King Tides: Flooding this Weekend and Beyond

We explore the phenomenon of king tides and their increasing impact on coastal cities, particularly Miami. King tides are naturally occurring high tides that occur during specific lunar phases, amplified by the sun's gravitational pull. We discuss how these tides, exacerbated by rising sea levels due to climate change, are causing frequent sunny-day flooding in Miami and other coastal areas. We highlight the growing threat of these floods to infrastructure, businesses, and the overall well-being of coastal communities. The need can’t be emphasize enough for proactive planning and investment in mitigation strategies to address the escalating problem of king tides.

Armed Militia Threatens Hurricane Helene Relief Workers in North Carolina Hampering Efforts

Armed Militia Threatens Hurricane Helene Relief Workers in North Carolina Hampering Efforts

Federal emergency response personnel in North Carolina were temporarily relocated due to reports of an "armed militia" threatening government workers involved in Hurricane Helene recovery efforts. Misinformation and rumors have been spreading throughout the affected areas, resulting in hostility towards federal agencies and a decline in the acceptance of aid offered by FEMA and the Forest Service. These incidents have also resulted in harassment and threats directed at federal employees. “Around 1 p.m. Saturday, an official with the U.S. Forest Service, which is supporting recovery efforts after Hurricane Helene along with the Federal Emergency Management Agency, sent an urgent message to numerous federal agencies warning that “FEMA has advised all federal responders Rutherford County, NC, to stand down and evacuate the county immediately. The message stated that National Guard troops 'had come across x2 trucks of armed militia saying there were out hunting FEMA.’” - Washington Post

Florida’s Insurance Crisis Deepens in the Wake of Hurricanes Helene & Milton

Florida’s Insurance Crisis Deepens in the Wake of Hurricanes Helene & Milton

Hurricane Milton is poised to severely impact Florida's already struggling property insurance market. This comes after the state faced record-breaking insurance costs and several insurance company failures, leading to the rise of Citizens Property Insurance Corporation, a non-profit that provides coverage to homeowners unable to find it in the private market. The state has been trying to stabilize the market through legal reforms and by encouraging private insurers to return, but Milton's potential devastation could push prices higher and further strain the system. Although Florida's real estate market remains resilient, a significant storm could lead to more insurers withdrawing from the state, leaving Citizens to cover a larger portion of the losses, potentially putting the state in a difficult financial position.
