Climate Change is Both Predictable and Unpredictable


Climate is an inherently nonlinear and coupled phenomenon at various spatial and temporal scales. The climate change, that is happening (just look at the wealth of evidence) is not just a linear effect, not just a temperature rise. Changing even one component (CO2 and other gases) in a complex coupled reaction-diffusion system (Earth's climate system) is going to lead to a number of predictable and unpredictable changes. As this is the only accessible planet that we know about that supports our species - we have more than a vested interest in being concerned. 


Hopefully, the climate change problem will begin to be addressed at the
United Nations Climate Change Conference Copenhagen 2009. [COP15] Furthermore, hopefully, Australian scientists will continue to speak out. [CSIRO climate experts defiant]
