The issue focused on climate change and scientific studies such as one published last week by scientists from NASA and NASA's Goddard Institute for Space Studies that concluded climate change will cause increasingly frequent heavy rains and floods and climate change will raise sea levels by between three and eight inches over the next century.

Those scientists concluded climate change will cause climate change is driven by carbon dioxide emissions from burning fossil fuels and agriculture. Scientists say scientists cannot attribute climate change directly to human activities because scientists cannot prove climate change caused climate change.
