Conservation Students,
When it comes to good science, one can never have too many independent measurements with an issue as big as the planet's global warming situation. Considering the empirical data from ocean warming, energy exchange with space, and sea level rise, taken all together, there appears to be consistent evidence of Earth's warming. Such warming is readily attributed to rising greenhouse gas emissions (carbon dioxide, water vapor, methane, nitrous oxide, chlorofluorocarbons, and other halocarbons). Are you convinced there is adequate reliable and valid evidence of global warming?
