In response to Nick's comments, I would like to add that the catastrophic problem of global warming can be combated, but no one can really be sure what the exact, "breaking point" may be. Some scientists say it's now, some say in 10 years, some may even say never.

Do I think that enough people in high positions around the world can successfully regulate carbon emissions in time to stave off these gloomy assessments? I honestly don't know. I definitely like to think of myself as an optimist, but with this issue in particular I think it will definitely be an uphill battle to say the least.
