The Center for Climate and Energy Solutions (C2ES) was named the world’s top environmental think tank in a global survey of top public policy research institutes.
The University of Pennsylvania’s 2011 Global Go-To Think Tank Rankings are based on a survey of more than 1,500 policymakers, scholars, journalists, think-tank executives and others worldwide. The survey assessed more than 5,300 organizations nominated in 30 categories to create a global list of top think tanks by region and policy area.
C2ES’s predecessor organization, the Pew Center on Global Climate Change, was named the world’s top environmental think tank in the same survey in 2009. The center began operating as C2ES in November 2011, and is listed in the new survey under its former name.
“While our name has changed, we remain as committed as ever to fact-based analysis and common-sense solutions to our climate and energy challenges,” said C2ES President Eileen Claussen. “We are thrilled to again be recognized as the world’s top environmental think tank. I’d like to commend the C2ES staff and thank all of our partners and supporters in the United States and abroad for helping to make this possible.”
The independent, nonpartisan center provides impartial information and analysis on energy and climate challenges; convenes policymakers and stakeholders to work toward consensus solutions; works with members of its Business Environmental Leadership Council and others to promote on-the-ground action; and promotes pragmatic, effective climate and energy policies at the state, national and international levels.
The annual survey, first published in 2007, is directed by James G. McGann, assistant director of the University of Pennsylvania’s International Relations Program and director of the Think Tanks and Civil Society Program.
The World Resources Institute and Chatham House ranked second and third, respectively, among the study’s top 30 environmental groups. Brookings Institution was named the top overall think tank. Additional categories in which the report ranks organizations include health policy, international development, and security and international affairs, among others.

Extreme Weather and Climate Change
Understanding the Link, Managing the Risk
Updated December 2011
Thousands of record-breaking weather events worldwide bolster long-term trends of increasing heat waves, heavy precipitation, droughts and wildfires. A combination of observed trends, theoretical understanding of the climate system, and numerical modeling demonstrates that global warming is increasing the risk of these types of events today. Debates about whether single events are “caused” by climate change are illogical, but individual events offer important lessons about society’s vulnerabilities to climate change. Reducing the future risk of extreme weather requires reducing greenhouse gas emissions and adapting to changes that are already unavoidable.
Typically, climate change is described in terms of average changes in temperature or precipitation, but most of the social and economic costs associated with climate change will result from shifts in the frequency and severity of extreme events. This fact is illustrated by a large number of costly weather disasters in 2010, which tied 2005 as the warmest year globally since 1880. Incidentally, both years were noted for exceptionally damaging weather events, such as Hurricane Katrina in 2005 and the deadly Russian heat wave in 2010. Other remarkable events of 2010 include Pakistan’s biggest flood, Canada’s warmest year, and Southwest Australia’s driest year. 2011 continued in similar form, with “biblical” flooding in Australia, the second hottest summer in U.S. history, devastating drought and wildfires in Texas, New Mexico and Arizona as well as historic flooding in North Dakota, the Lower Mississippi and in the Northeast.
Munich Re, the world’s largest reinsurance company, has compiled global disaster for 1980-2010. In its analysis, 2010 had the second-largest (after 2007) number of recorded natural disasters and the fifth-greatest economic losses. Although there were far more deaths from geological disasters—almost entirely from the Haiti earthquake—more than 90 percent of all disasters and 65 percent of associated economic damages were weather and climate related (i.e. high winds, flooding, heavy snowfall, heat waves, droughts, wildfires). In all, 874 weather and climate-related disasters resulted in 68,000 deaths and $99 billion in damages worldwide in 2010.
The fact that 2010 was one of the warmest years on record as well as one of the most disastrous, begs the question: Is global warming causing more extreme weather? The short and simple answer is yes, at least for heat waves and heavy precipitation. But much of the public discussion of this relationship obscures the link behind a misplaced focus on causation of individual weather events. The questions we ask of science are critical: When we ask whether climate change “caused” a particular event, we pose a fundamentally unanswerable question (see Box 1). This fallacy assures that we will often fail to draw connections between individual weather events and climate change, leading us to disregard the real risks of more extreme weather due to global warming.
Climate change is defined by changes in mean climate conditions—that is, the average of hundreds or thousands events over the span of decades. Over the past 30 years, for example, any single weather event could be omitted or added to the record without altering the long-term trend in weather extremes and the statistical relationship between that trend and the rise in global temperatures. Hence, it is illogical to debate the direct climatological link between a single event and the long-term rise in the global average surface temperature.
Nonetheless, individual weather events offer important lessons about social and economic vulnerabilities to climate change. Dismissing an individual event as happenstance because scientists did not link it individually to climate change fosters a dangerously passive attitude toward rising climate risk. The uncertainty about future weather conditions and the illogic of attributing single events to global warming need not stand in the way of action to manage the rising risks associated with extreme weather. Indeed, such uncertainty is why risk managers exist – insurance companies, for example – and risk management is the correct framework for examining the link between global climate change and extreme weather.
An effective risk management framework accommodates uncertainty, takes advantage of learning opportunities to update understanding of risk, and probes today’s rare extreme events for useful information about how we should respond to rising risk. Risk management eschews futile attempts to forecast individual chaotic events and focuses on establishing long-term risk certainty; that is, an understanding of what types of risks are increasing and what can be done to minimize future damages. An understanding of the meaning of risk and how it relates to changes in the climate system is crucial to assessing vulnerability and planning for a future characterized by rising risk.

 Karl et al., Weather and Cliamte Extremes in a Changing Climate, Op. cit.
For the second year in a row, unprecedented numbers of extreme weather events have occurred across the globe. However, more of 2011’s impacts occurred in the United States. From the drought in Texas to the floods in the Midwest and Northeast, this past year underscored the huge economic costs associated with extreme weather. While specific weather events are not solely caused by climate change, the risks of droughts, floods, extreme precipitation events, and heat waves are already climbing as a result of climate change. This year reminded us of our vulnerability to those events.

2011 has been a record year for weather disasters. From historic drought in Texas to record-breaking flooding in North Dakota, to an unprecedented number (> 5600) of record high temperatures across the United States, much of the country has seen severe damage from extreme weather. The year is not yet over, and economic losses already exceed $45 billion.
This lunch briefing with leading experts examines extreme weather hazards, with a case study on the Texas drought, their relationship to changes in our climate, and how the country can better prepare for such events. Speakers at this lunch briefing include:
- Michael Oppenheimer, Albert G. Milbank Professor of Geosciences and International Affairs, Princeton University; Coordinating Lead Author, IPCC Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation
- John Nielsen-Gammon, Texas State Climatologist and Regents Professor of Atmospheric Sciences, Texas A&M University
- Frank Nutter, president of the Reinsurance Association of America

The Intergovernmental Panel on Climate Change (IPCC) released a “special report” (that’s what they call topical reports they publish in between their better known comprehensive assessments) today that is worth a close look for anyone who wants to start getting ready for a future with weirder and often harsher weather.
About a year ago I published an opinion editorial taking the Intergovernmental Panel on Climate Change (IPCC) to task for neglecting risk-based information to help decision makers cope with inevitable uncertainties about the future impacts of climate change:
Since uncertainty is endemic to the future, when the second IPCC assessment concluded in 1995 that ‘The balance of evidence suggests a discernable human influence on the global climate’, the IPCC should have reconvened around the risk implications of this probable human influence. Instead, it redoubled its effort to reduce physical science uncertainties [which will not be resolved before action is required].
For those of you who came to our website today expecting to find information and resources from the Pew Center on Global Climate Change, please don’t click away. Today we announced an exciting transition. We are now C2ES — the Center for Climate and Energy Solutions. In addition to changing our name, we’ve refreshed our mission and strategic approach, updated our website, and made other changes to ensure that we can continue to craft real solutions to the energy and climate challenges we face today.
Yes, a great deal has changed in the last 24 hours. But what hasn’t changed is the need for straight talk, common sense and common ground. Today’s climate and energy issues present us with real challenges — and real opportunities as well. This is about protecting the environment, our communities and our economy. And it is about building the foundation for a prosperous and sustainable future.
Greenhouse gas (GHG) intensity is a measure of the amount of emissions relative to GDP. it is highest in Russia and China with the United States below the world average.
