Hitting Close to Home | Global Warming is Fueling Extreme Weather Across the U.S.

Every year, weather-related disasters injure or kill hundreds of Americans and cause billions of dollars in damage. [1] Many of the risks posed by extreme weather will likely increase in a warming world. Scientists have already noted increases in extreme precipitation and heat waves as global warming raises temperatures and exacerbates weather extremes. [2]
   

Weather-related disasters affect millions 

  • Since September 2010, counties housing 99 percent of the total Florida population (over 19 million Americans) were affected by federally-declared weather-related disasters.
  • Florida experienced five weather-related disasters including severe storms, tornadoes, floods, tropical storms and droughts since September 2010. 

New Online Map Shows Weather-Related Disasters and Extreme Weather’s Personal Impact

Environment Florida’s new interactive extreme weather map shows weather-related disasters in the United States over the last five years and tells the stories of the people and communities who have endured some of those disasters

Map visitors can focus in on specific types of weather and even add their own stories of how extreme weather has affected their lives.


Extreme weather causes widespread destruction

  • In April 2015 severe storms raged across the South and Southeastern states, including Florida. The total estimated costs of the storms were over $1 billion
  • In April 2014 torrential rainfall in the Florida panhandle caused major flooding and Pensacola set a new 2-day precipitation record of 20.47 inches. 
  • In August 2012 Hurricane Isaac led to a large storm surge and flooding rains, which created damage to several southeastern states, including Florida. Hurricane Isaac caused at least 9 deaths and $2.9 billion in estimated damages in the affected regions. 
  • Since 2010 extreme weather events caused at least 7 power outages in Florida, including one that lasted 6 days in 2011. [3]


Weather extremes are becoming more common 

Globally, 2015 was Earth’s hottest year on record, surpassing 2014. [4] Many types of extreme weather are expected to become more frequent or severe in a warming world, which could lead to more weather-related disasters. 

  • Tropical Storms and Hurricanes: Global warming has the potential to make tropical storms more destructive. Hurricanes and other coastal storms are likely to be more powerful [5] and rainier, [6] while storm surges could be more destructive as sea levels rise. [7]
  • Heavy Rain and Snow: Extreme precipitation is already increasing; continued trends could increase the risk of intense downpours, heavy snowstorms and severe flooding. [8]
  • Droughts and Wildfires: While global warming is anticipated to bring more rain to some areas, it will also likely elevate temperatures and extend dry spells. The potential for stronger drought—and greater area burned by wildfires—will increase, particularly in the West and Southwest. 
     

Florida must cut global warming pollution 

To protect our children and our communities from a future of worsening extreme weather, Florida, its cities, and the nation should limit global warming pollution to levels consistent with the Paris Climate Agreement—at least 40 percent below 1990 emissions by 2030 and at least 80 percent by mid-century. Essential steps to meet these targets include: 

  • Effectively implement the Clean Power Plan. Florida should drop its legal challenge to the Clean Power Plan, the largest single step that the United States has taken to reduce dangerous carbon pollution from power plants. Moreover, the state should actively prepare to comply with the policy while court challenges play out. A strong implementation plan should reduce more pollution than the minimum requirement, focus on clean energy solutions and ensure that polluters pay. 
  • Maximize energy efficiency. Florida and its cities should expand energy efficiency programs and adopt net-zero energy building codes and retrofit standards. 
  • Shift to 100 percent clean power. Meeting our climate goals will require accelerating deployment of clean, renewable energy sources such as solar and wind power. The state should enact a clean energy standard and increase clean energy incentives. 
  • Use clean energy for transportation and heating. Florida should shift energy for transportation and heating away from fossil fuels and toward electricity or other forms of clean energy. 
  • Keep dirty fuels in the ground. To protect the global climate and our health, the nation must cease construction of any new fossil fuel infrastructure and leave our coal, oil and gas reserves in the ground.
