Levels of carbon dioxide (CO2), the principal gas that drives global warming, are now 27 pct higher than at any point in the last 650,000 years, according to research into Antarctic ice cores. The more we learn about climate change, its rate and its impacts; the more the scale and magnitude of human impact upon global ecological systems becomes apparent. We are really in trouble as advances in climate change science (and obvious impacts just outside our door) indictate we may have reached or being reaching a tipping point where abrupt and major climate shifts are underway. It is clear that immediate efforts to significantly reduce greenhouse gas emissions are absolutely vital to humanity's survival. Vague commitments to adapt to changes and reduce the rate of growth of greenhouse gases will doom humanity to eco-armaggedon. Climate change is deadly serious - and either we accept that ecological sustainability takes preference over unbridled economic growth or we die.

Core Evidence That Humans Affect Climate Change

An ice core about two miles long — the oldest frozen sample ever drilled from the underbelly of Antarctica — shows that at no time in the last 650,000 years have levels of the greenhouse gases carbon dioxide and methane been as high as they are today... the core and shows that carbon dioxide levels today are 27% higher than they have been in the last 650,000 years and levels of methane, an even more powerful greenhouse gas, are 130% higher...
