President Bush's new climate change proposal was greeted with skepticism and scorn on Wednesday, as some pundits believe the proposal is too little, too late from a leader who has largely declined to address global warming.

One organization that is looking for more dramatic action from the federal government on the issue is former Vice President Al Gore's Alliance for Climate Protection. The nonprofit group, funded largely by Gore himself, has launched the second TV ad of its "We Campaign," a $300 million advertising and grassroots effort whose "ultimate aim is to halt global warming," according to the campaign's Web site.

"Unlikely Alliance" (subscription) features a duo that most Americans would never expect to see on the same side of a political battle -- liberal activist Rev. Al Sharpton and conservative televangelist Pat Robertson. The two talk playfully about their disagreements but stress that climate change is an issue that people of all political stripes can agree on.

"Al, let's face it -- we're polar opposites," Robertson says, as the two sit side by side on a couch at the beach. "We couldn't be further apart... Except on one issue," Sharpton quips. They go on to stress how "extremely important" taking care of the planet is and that "we all need to work together -- liberals and conservatives."

Analysis from HCD Research suggests that ACP's bipartisan message in its latest spot may be a smart strategy, as Republicans and Democrats had very different reactions to the group's first release (subscription).

While all viewers responded positively to the patriotic images at the beginning of the spot, Republicans demonstrated skepticism as soon as the word "climate" was mentioned.

Viewers of different age groups also tended to react differently to the campaign's first ad. Young people responded more positively to ACP's message, while older viewers appear to need some more convincing.
