This is bad news, apparently CO2
levels have hit a 650,000 year high.
The measurements are disturbing: Levels of carbon dioxide have climbed from
280 parts per million two centuries ago to 380 ppm today. Earth's average temperature,
meanwhile, has increased more than half a degree Celsius in recent decades,
a relatively rapid rise. Many climate specialists warn that continued warming
could have severe impacts, such as rising sea levels and changing rainfall patterns.
