Anthropocene-CO2 Levels, The highest of past 800,000 years
If you ask any environment scientist whether the climate change is happening, 95% of them return the answer YES. We are all well aware of rising temperatures and melting ice caps. The changes are palpable as we have witnessed many catastrophic events like record low sea ice of Arctic in Sep 2007 and 2012, Melting of Ice in Greenland in mid July, 2012 and rising of sea water level by 6 cm between 1990 to 2010. The sinks of CO2 are inadequate to subside the rising levels of this gas and thus causing global warming.
During ice ages, CO2 levels were around 200 parts per million (ppm), and during the warmer inter-glacial periods, they hovered around 280 ppm (see fluctuations in the graph). In 2013, CO2 levels surpassed 400 ppm for the first time in recorded history. It is evident that the increase of 80 ppm has occurred during last 55 years i.e. the industrial revolution period. This recent relentless rise in CO2 shows a remarkably constant relationship with fossil-fuel burning, and can be well accounted for based on the simple premise that about 60 percent of fossil-fuel emissions stay in the air.
It is anticipated that the levels of CO2 will continue to rise to the order of 1500 ppm if the anthropogenic activities carry on at same pace.
Google the word Anthropogenic which will give a result of use over time which says, it is originated and widely used from past half-century itself.
Anthropocene: relating to or denoting the current geological age, viewed as the period during which human activity has been the dominant influence on climate and the environment.
