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 in New York 

  • Every New York citizen lives in a county that was affected by at least one federally declared weather disaster since 2010. 
  • Since September 2010, New York experienced 11 weather-disasters, including severe storms, tornadoes, floods, tropical storms, snow and ice storms, and droughts. 

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

Environment New York’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 August 2014 a slow-moving storm system resulted in 24-hour rainfall exceeding 12 inches in New York’s Long Island. The total estimated costs of the flooding events across Michigan and the northeast, including New York, were $1 billion. 
  • In October 2012 Hurricane Sandy caused extensive damage across New York due to high wind and a coastal storm surge. Hurricane Sandy caused at least 159 deaths and the total estimated costs were $67.6 billion in the affected regions. 
  • Since 2010 extreme weather caused at least 23 power outages in New York, including one that lasted 15 days in Long Island in 2012. [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. 

 

New York must cut global warming pollution 

To protect our children and our communities from a future of worsening extreme weather, New York, its cities, and the nation should limit global warming pollution to levels consistent with the Paris Climate Agreement. The state has set a target of 40 percent below 1990 emissions by 2030 and 80 percent by mid-century. Continued leadership from New York is essential. Key steps include: 

  • Strengthen the Regional Greenhouse Gas Initiative. New York should reduce regional power plant pollution by more than half in the next 15 years, capping emissions at less than 40 million tons per year by 2030. 
  • Maximize energy efficiency. New York and its cities should accelerate 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 offshore wind power. The state should start by implementing its new 50 percent by 2030 clean energy standard. 
  • Use clean energy for transportation and heating. New York 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.
