Klaus Lackner's "artificial tree"

Despite the fact that the impacts of manmade climate change are already being felt and that failure to mitigate these effects by lessening fossil fuel CO2 emissions could result in dire consequences, policies enacted to reduce these emissions have been grossly insufficient. While there is no one silver bullet to “solve” climate change, many technologically [...]

I am a wild carbon atom,
To others I’ve sometimes been bound,
Not locked in some hard, rocky stratum,
I’m telling you: I get around!

The most important lessons drawn from geology are that the earth’s climate can change radically and that the pace of change can be rapid. The precision of measurement is currently too poor to give an exact answer to a critical question, At what carbon dioxide level are we in danger of melting Antarctica? However, while crude, these estimates suggest that this threshold will be reached in 150-300 years, if carbon dioxide levels continue to rise at the current rate.
