“Few challenges facing America — and the world — are more urgent than combating climate change…Many of you are working to confront this challenge….but too often, Washington has failed to show the same kind of leadership. That will change when I take office.”

So began Barack Obama in a video message addressed to the Bi-Partisan Governors Global Climate Summit just weeks after the election. However, while he supports an 80 percent reduction of emissions by 2050 through a cap and trade bill, Obama’s nominations leave us uncertain of how the new administration intends to take on global warming.  

The President-elect’s energy team marks a stark contrast from George W. Bush’s inertia on climate change. Consider Steven Chu, our next Secretary of Energy: As a leading voice in the science community on the dangers of excess CO2, he will be an advocate for the development of alternatives to limit fossil fuel consumption.

Likewise, former head of the Environmental Protection Agency Carol Browner will serve as Assistant to the president for energy and climate change. Her appointment makes additional strides toward an aggressive approach because she will coordinate agency climate change policies while balancing economic and national security considerations. Another strong pick is Lisa Jackson to head the EPA who is expected to play a critical role toward establishing cap-and-trade legislation. These nominations demonstrate that science will once again be taken seriously in government.

The science team looks equally promising. John Holdren as science advisor provides Obama with an international expert on climate and energy who has long advocated for firm government regulation of greenhouse gas emissions. Adding momentum, marine scientist Jane Lubchenco should guide the Commerce department’s focus on climate policy through her role as head of the National Oceanic and Atmospheric Administration.
