Ruined Summer: How Climate Change Scorched the Nation in 2012
Is climate change ruining our summers?
National Wildlife Federation
It is certainly altering them in dramatic ways and rarely for the better. The summer of 2012 has been full of extreme
weather events connected to climate change. Heat records have been broken across the country, drought conditions
forced the United States Department of Agriculture (USDA) to make the largest disaster declaration in U.S. history,
and wildfires have raged throughout the West. New research by world-renowned climate scientist James Hansen
confirmed that the increasingly common extreme weather events across the country, like record heat waves and
drought, are linked to climate change.
This report examines those climate change impacts whose harm is acutely felt in the summer. Heat waves; warming
rivers, lakes, and streams; floods; drought; wildfires; and insect and pest infestations are problems we are dealing
with this summer and what we are likely to face in future summers.

Unfortunately, hot summers like this will occur much more frequently in years ahead. Climate change means far more
than hotter weather: as the atmosphere heats up, climate systems are altered in ways that impact forests, lakes,
prairies, rivers, wetlands, and other habitats, as well as the communities and wildlife that depend on them. Average
water temperatures in streams, rivers, lakes, and oceans are increasing, precipitation patterns are changing, and
extreme weather emergencies such as droughts and floods are becoming both more frequent and severe.
To understand how 2012 represents what we can expect in the future, we must understand how climate change is
connected to the weather we are experiencing. A recent scientific study published in the Bulletin of the American
Meteorological Society, “Explaining Extreme Events of 2011 From a Climate Perspective”, found that some of the
weather extremes around the world have become far more likely because of climate change. For example, climate
change made the severe heat wave Texas experienced in 2011 twenty times more likely to occur than it would have
been in the 1960s. Climate change made this heat wave hotter and last longer. Penn State geosciences professor
Richard Alley puts it this way: “Humans have made some extreme weather events more likely, and they are happening.
Just as a back-street gambler might beat someone in an honest game but has a better chance with loaded dice,
nature might have caused this summer’s weather but we gave it a boost.”
By taking action now to reduce the
amount of carbon pollution from the
nation’s largest sources, and providing
support for wildlife-friendly wind, solar,
geothermal and biomass energy, we can
reduce the impact of a changing climate
and power a new clean energy economy
for all Americans.
If we don’t enact the solutions we have on
hand to reduce carbon pollution, wildlife,
people, and our summers will suffer.
