Uncertainty in the carbon cycle is greater than computer-generated models account for. Large generalizations have left out many smaller processes that may or may not be correctly compensated for. The influence of global-warming on the terrestrial carbon cycle, as well as the net flux of carbon from and to terrestrial bodies, could alone account for these imbalanced models. Another factor could be that our oceans act like sponges that absorb and sequester the so-called "missing sink".
Satellites and Data Analysis
Weeks after NASA's satellite crashed and burned, we look at available data and attempt to pinpoint the alarming amount of carbon dioxide that remains unaccounted for in computer-generated models. The Canadian mini-satellite launched in the summer of 2008 is doing the same analysis that NASA's OCO (Orbiting Carbon Observatory) satellite was destined to do, but at a fraction of the cost.
IPCC Reports
The IPCC (Intergovernmental Panel on Climate Change) is piecing together its fifth climate change report, which is not forecasted to be published until 2014. The IPCC's last report, published in 2007, is aimed at awareness of climate change. The panel aims at surfacing the anthropogenic effects we have had on our environment with noticed loss in snow cover, increased sea-surface temperatures and rising greenhouse gases. The IPCC has also gone so far as to identify mitigation efforts and quantified what is needed to prevent catastrophic long-term effects on global climate.
Denial and Hope
Still to this day, we continue to see growth in atmospheric concentrations of carbon dioxide, denial that we are experiencing abnormal climate changes, and are ratifying the Kyoto Protocol. Will the ideas of emissions trading, clean development mechanism, and joint implementation help solve our crisis? When will there be solid proof that we have decreased our burden on Earth?
