Greenhouse Gas Is Ramping Up Fast
- The latest real-world measurements of carbon dioxide levels in Earth's
atmosphere show that it's increasing at breakneck speed, despite some
preliminary efforts in some parts of the world to rein in fossil fuel
burning � the main source of the surplus greenhouse gas.
The new data reported in Tasmania last week shows there were 7.9 billion
tons of carbon emitted in 2005 and that the 1 percent per year carbon
dioxide concentration increase rate of the 1990s has already jumped to
2.5 percent per year. These numbers all point to a worst-case scenario
greenhouse effect and global warming.
