WASHINGTON (Reuters) - Dueling videos -- one starring Arnold Schwarzenegger, the other featuring a "typical" U.S. family shivering in an underheated house -- are focusing debate on a Senate bill aimed at cutting climate-warming pollution.

Schwarzenegger, the action star-turned-Republican governor of California, stands in front of a redwood grove and intones, "Climate change: it's a test of leadership." He and two other governors, posed in natural settings, urge viewers to press their senators to approve the so-called Lieberman-Warner bill.

"We're not here to be a roadblock," U.S. delegation leader Harlan Watson said on the opening day of a December 3-14 meeting of almost 190 nations in Bali, Indonesia, seeking to agree a roadmap to work out a successor to Kyoto which runs to 2012.

BALI (Reuters) - Climate talks launched in Bali on Monday must assure investors of future government backing for climate-friendly energy and building projects, said the host of the meeting, Indonesia's Environment Minister Rachmat Witoelar.

The talks in Bali, attended by some 190 countries, will try and lay the foundations for a new climate change deal in time to replace or extend the Kyoto Protocol from 2013.
