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.

As we enter 2013, there are signs of growth and economic advancement around the world. The global middle class is booming. More people are moving into cities. And the quality of life for millions is improving at an unprecedented pace.

Yet, there are also stark warnings of mounting pressures on natural resources and the climate. Consider: 2012 was the hottest year on recordfor the continental United States. There have been 36 consecutive years in which global temperatures have been above normal. Carbon dioxide emissions are on the rise – last year the world added about 3 percent more carbon emissions to the atmosphere. All of these pressures are bringing more climate impacts: droughts, wildfires, rising seas, and intense storms.

All is not lost, but the window for action is rapidly closing. This decade--and this year--will be critical.

Against that backdrop, experts at WRI have analyzed trends, observations, and data to highlight six key environmental and development stories we’ll be watching in 2013.

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.

Temperature

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:

The U.S. Environment Protection Agency finalized the Boiler Maximum Achievable Control Technology (MACT) rule today to protect people from exposure to toxic air pollution from industrial, commercial, and institutional boilers. By encouraging industry to use cleaner-burning fuels and to make efficiency improvements, Boiler MACT will modernize U.S. industry, reduce toxins, and cut carbon pollution.

The Boiler MACT rules, which are required by the Clean Air Act amendments of 1990, will only target the most significant sources of toxic air pollution. Most boiler-based emissions come from a small handful of very large industrial and commercial facilities that operate coal, oil, and biomass-fired boilers. As such, according to EPA:

• Fewer than 1 percent of all U.S. boilers will be required to reduce their emissions to levels that are consistent with demonstrated maximum achievable control technologies, or MACT standards. Operators of these types of boilers will have three years to reduce toxic air pollution and meet new emissions limits.

• A larger subset of U.S. industrial, commercial, and institutional boilers (roughly 13 percent) would not be required to meet the specific MACT standards, but would need to reduce their toxic air emissions through other means (as described below).

• About 86 percent of all U.S. boilers are relatively small, limited-use, or gas-fired boilers, and are not covered by the new rules.

"Think globally, act locally" is a slogan that aptly describes what I witnessed last week at the 4th Annual Southeast Florida Climate Leadership Summit. At the event, local government officials from four counties gathered to discuss how to mitigate and adapt to climate change’s impacts.

Yep, you heard that correctly – government officials in the United States—in a “purple” state, no less—came together in a bipartisan manner to address climate change mitigation and adaptation. In fact, mayors, members of Congress, county commissioners, and officials in charge of water issues in the state discussed how to move forward with action plans in response to sea-level rise – a climate change impact which is not theoretical, but happening now.

Putting Aside Partisanship for Action

Unlike Congress, these public officials aren't debating the facts of climate change and its impacts or whether we should act. They see current effects and understand that in the face of streets flooding more regularly, drinking water supplies threatened by salinization, and models showing that some neighborhoods could become uninhabitable, what political party you support is irrelevant. Climate change impacts like sea level rise don't discriminate between Democrats and Republicans.

In the UNFCCC international climate negotiations, “ambition” refers to countries’ collective will to cut greenhouse gas (GHG) emissions enough to keep global average temperature increase below 2°C. While most countries have made international pledges to limit GHG emissions, these pledges are not “ambitious” enough to add up to the GHG cuts needed to meet the 2°C temperature goal. That’s why many groups are calling on parties in Doha to step up their commitments. Equally important, though, is ensuring that countries are effective in implementing domestic policies that meet – or exceed – the international commitments they have made already.

What Makes for an Effective Domestic Climate Policy?

The “implementation deficit” – a difference between the expected and actual amount of emissions reductions of an enacted policy—stems from a lack of complete implementation of a climate policy. This kind of “deficit” is well documented in a number of policy sectors, with significant implications for the countries’ abilities to meet GHG-reduction targets. Conversely, when climate policies are effectively implemented, they demonstrate that mitigation actions can work, in turn encouraging other countries to adopt similar policies and actions.

The effectiveness of any policy depends on several key factors, including:
