Atmospheric CO2 emissions

It’s clear that CO2 and planetary warming are inextricably linked. We currently have more CO2 in the atmosphere than at any time in the last 600,000 years.

Planetary warming is having an impact. A presentation given by James Balog demonstrates time lapse photography giving graphic and visual representation of glaciars melting faster than scientist had predicted just a year or two ago. This melting ice is not only the “canary in the mine” it alone could cause a dramatic rise in sea levels with catastrophic effects. Scientific data demonstrating greater anthropocentric emissions and faster geographical changes than expected and modeled are demonstrating a trajectory outside the IPPC’s worst case scenarios.  There’s an increasing chorus of scientist, noble prize winners, big business and local community members, all calling from a rapid response. Many scientists now believe that for climate safety we must stabalise our atmospheric emissions at 350ppm and that we have less than 100 months and counting before we cross a threshold;

“atmospheric concentrations of greenhouse gases will begin to exceed a point whereby it is no longer likely we will be able to avert potentially
irreversible climate change. ‘Likely’ in this context refers to the definition of risk used by the Intergovernmental Panel on Climate Change (IPCC) to mean that, at that particular level of greenhouse gas concentration, there is only a 66 – 90 per cent chance of global average surface
temperatures stabilising at 2º Celsius above pre-industrial levels.1 Once this concentration is exceeded, it becomes more and more likely that we will overshoot a 2º C level of warming. This is the maximum acceptable level of temperature rise agreed by the European Union and others as necessary to retain reasonable confidence of preventing uncontrollable and ultimately catastrophic warming. We also believe this calculation to be conservative”.
