While Japanese prime Minister Yoshihiko Noda has been trying to persuade local communities it is safe to restart two nuclear reactors, 70% of Japanese say their country should reduce its reliance on nuclear energy.

There has been a modest increase over the past two years in the percentage of Americans who say there is solid evidence of global warming, although substantially fewer Americans say there is solid evidence of global warming than did so from 2006 to 2008.

Fifty years after the first American manned space flight, nearly six-in-ten say it is essential that the U.S. continue to be a world leader in space exploration and a majority say it has been a good investment for the country.

Support for the increased use of nuclear power has declined amid the ongoing nuclear emergency in Japan. But with the surge in gas prices, support for increased offshore oil and gas drilling is growing.

Americans want expanded exploration and development of coal, oil and gas in the U.S. but also want limits on carbon dioxide and other greenhouse gas emissions. Michele Obama's favorability stays strong but the president's and Sarah Palin's popularity slip.

Americans are critical of the government's response to the environmental disaster in the Gulf, but even more so of BP. Support for offshore oil drilling is down, though Republican opinion is unchanged.
