Stricken by record heat, wildfires, drought, and hurricanes, the United States endured devastating impacts from extreme weather and climate events in 2012. This fact sheet outlines the records broken by these extreme events, which are expected to become more frequent as the climate warms.
As we’ve seen recently with Hurricane Sandy, epic drought, and wildfires, climate change visibly impacts lives and livelihoods throughout the United States. Global warming’s effects extend beyond people, wildlife, and ecosystems, though: They’re threatening America’s energy infrastructure.
Today, I testified on this very subject before the Energy and Power Subcommittee of the House Energy and Commerce Committee at a hearing entitled “American Energy Security and Innovation: An Assessment of North America’s Energy Resources.” I highlighted the energy risks and opportunities climate change presents, the role that clean energy should play, and actions Congress can take to mitigate global warming’s threats. Excerpts from the testimony are included below, or you can download my full testimony.
Climate Change Threatens Energy Infrastructure
Climate instability directly affects the future security of the U.S. energy sector. For example:
- Each successive decade in the last 50 years has been the warmest on record globally, and according to the U.S. National Climate Assessment, average temperatures will continue to rise. Energy demand is directly impacted by these temperature increases. A recent study in Massachusetts estimates that rising temperatures could increase demand for electricity in the state by 40 percent by 2030.
Temperatures hit an unseasonably warm 61˚F in Washington D.C. earlier this week. The Middle East is blanketed in record rainfall and rare heavy snowfall, ending a nearly decade-long drought. Australia witnessed its hottest day on record this past week, stoking wildfires. And China is experiencing a bitterly cold winter, where temperatures are the lowestthey’ve been in almost three decades. We’re only two weeks into 2013, and already we are getting a reminder of the extreme year we just emerged from.
2012: A Year of Extreme Weather
How extreme were last year’s weather and climatic events? In the continental United States, 2012 was the hottest year on record and the second most extreme year, according to scientists from the National Oceanic and Atmospheric Administration (NOAA). On top of that, the United States experienced 11 extreme weather events that each caused more than $1 billion in damages.
And 2012 did not spare the rest of the world; it brought severe drought to the African Sahel, torrential rains to China, Europe’s worst cold snap in 25 years, and flooding in Manila and Bangladesh, among other devastating events.
We took stock of 2012’s extreme events in an interactive timeline. It is by no means comprehensive, but reminds us how climate change is affecting global communities and citizens’ lives, livelihoods, infrastructure, and ecosystems.
The draft U.S. National Climate Assessment was released last week, confirming that the climate is changing, that it is primarily due to human activities, and that the United States is already being adversely impacted. These top-line messages should come as no surprise, as they reconfirm the major findings of previous National Climate Assessments and of the Intergovernmental Panel on Climate Change’s recent reports.
But the 1,000-plus pages of the Assessment also carry important findings—many of which have not been highlighted in media reports thus far. WRI’s experts reviewed the assessment in its entirety. Below, we boil down some of the highlights from this comprehensive body of work, including its findings on how increases in greenhouse gas emissions have impacted temperature, sea level rise, precipitation, ice cover, ecosystems, and human health in the United States and globally.
Build-up of greenhouse gases in the atmosphere has already caused America’s average temperature to rise by 1.5 ˚F since 1895, according to the assessment. With continued increases in emissions, U.S. temperatures are projected to increase 5-10˚F by the end of the century. Rising temperatures have implications for human health, drought, storm intensity, and species and ecosystem health, among others. A few other notable statistics include:

A new federal report reveals alarming statistics on climate change. According to the 3rd National Climate Assessment, released in draft form today from the U.S. Global Change Research Program, the world could warm by more than 12°F by the end of the century if action isn’t taken to reduce greenhouse gas emissions.
“The evidence is clear and mounting,” said WRI’s president, Andrew Steer, in response to the report. “The United States sits at the center of the climate crisis. Record heat is devastating crops, rivers are drying up, and storms are bearing down on our cities. Climate change is taking its toll on people and their economies, and will only become more intense without a strong and rapid response here in the United States and around the globe. It’s not too late to take action, but given lags in policy and geophysical processes, the window is closing.”
This assessment comes on the heels of the National Oceanic and Atmospheric Administration’s (NOAA) announcement earlier this week that 2012 was the hottest year on record for the contiguous United States. According to NOAA’s National Climate Data Center, the country saw 356 all-time temperature highs (and only four all-time lows) tied or broken and experienced 11 extreme weather events each causing more than $1 billion in damages.
Here are a few of the report’s key findings:

According to new data, 2012 was a chart-topping year for the United States – but not in a good way.
The National Oceanic and Atmospheric Administration’s (NOAA’s) National Climate Data Center (NCDC) recently declared 2012 to be the hottest year on record for the contiguous United States. This year shattered the previous record temperature, set in 1998, by 1.0°F. The year was also marked by 11 extreme weather events that each caused more than $1 billion of damages.
In a year that brought the United States record-breaking wildfire activity, an ongoing drought, and Hurricane Sandy, perhaps these announcements aren’t surprising. But they are troubling: Record-breaking temperatures and the rising frequency of extreme weather events illustrate that climate change is happening. These trends are expected to worsen the longer we delay serious action to reduce carbon pollution.
Take a look at a few of the figures illustrating the intensity and impacts of 2012’s extreme weather and climate events:
This year has been one of those worst-of-years and best-of-years. In its failures, there are signs of hope.
An unprecedented stream of extreme weather events worldwide tragically reminded us that we’re losing the fight against climate change. For the first time since 1988, climate change was totally ignored in the U.S. presidential campaign, even though election month, November, was the 333rd consecutive month with a global temperature higher than the long-term average. A WRI report identified 1,200 coal-fired power plants currently proposed for construction worldwide. The Arctic sea ice reached its lowest-ever area in September, down nearly 20 percent from its previous low in 2007. And disappointing international negotiations in June and December warned us not to rely too much on multilateral government-to-government solutions to global problems.
But 2012 was also a year of potential turning points. A number of new “plurilateral” approaches to problem-solving came to the fore, offering genuine hope. A wave of emerging countries, led by China, embraced market-based green growth strategies. Costs for renewable energy continued their downward path, and are now competitive in a growing number of contexts. Bloomberg New Energy Finance reports that global investment in renewable energy was probably around $250 billion in 2012, down by perhaps 10 percent over the previous year, but not bad given the eliminations of many subsidy programs, economic austerity in the West, and the sharp shale-induced declines in natural gas prices. And the tragedy of Hurricane Sandy, coupled with the ongoing drought covering more than half of the United States (which will turn out to be among the costliest natural disasters in U.S. history) may have opened the door to a change of psychology, in turn potentially enabling the Obama Administration to exhibit the international leadership the world so urgently needs, as many of us have advocated.
Doha, Qatar, may not the first place that you’d pick for a global conference—many people would be hard-pressed to find it on a map. Yet, it’s the location of this year’s global UN climate negotiations (COP 18).
It’s midway through the final week of the negotiations, yet there’s an eerie calm in the sprawling conference hall. The scene here is different than the past two years (in Durban and Cancun, respectively), both of which were filled with tension and even moments of drama. Certainly, no one expected a major breakthrough this year, but the lack of urgency here is disquieting.
The Climate Change Risks Are Increasingly Clear
What’s happening inside the conference center stands in stark contrast to what we’re witnessing outside. Just yesterday, an unusual and massive storm, Typhoon Bopha, swept across the Philippines, taking hundreds of lives and displacing thousands more. While typhoons are common in the Philippines, this storm is the most southern on record and arrived particularly late in the season. Meanwhile, people in the eastern United States and Caribbean are still recovering from Hurricane Sandy. And, in India, a new report warns that more droughts loom as monsoons will bring 70 percent less water in the years ahead.
Hurricane Sandy is the most recent event to expose the vulnerability of the United States to extreme weather, with costly disruptions to businesses, people’s livelihoods, and critical infrastructure. This fact sheet by WRI examines the connection between Hurricane Sandy and climate change as...
With half of all Americans living near the ocean, Hurricane Sandy provides a wake-up call for state and municipal authorities in coastal areas nationwide. New York’s Governor Andrew Cuomo is leading the way, pledging a new generation of storm-resistant infrastructure and forming three commissions to explore how the state can better prepare for climate change’s coming impacts.
Sandy wrought a 1,000-mile trail of damage in towns and cities along the East Coast shoreline. As climate change intensifies, more severe storms (and storm surges), rising seas, extreme heat, and other destructive impacts loom on the horizon. How can New York City; Newark, N.J.; and other cities hit by Sandy rebuild in ways that avoid a repeat of the devastation that deprived millions of the basic essentials of modern life? How can other coastal cities adapt to become more resilient to a warming climate?
Put simply, they need to “build back better,” a phrase first coined by President Clinton following the 2004 Asian tsunami. In practice, this means coupling short-term efforts to get communities back on their feet with longer-term urban development that adapts to expected climate change impacts.
As they seek to make our coastal cities and towns more climate resilient, urban leaders should adopt three key approaches that we believe will be critical to success:
