Although we label this era a "revolution," its title is somewhat misleading.
' The Industrial Revolution' refers to a period of massive economic, technological, social and cultural change which affected humans to such an extent that it's often compared to the change from hunter-gathering to farming.
C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.
C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope).
Abram said the findings, published on Wednesday in the journal Nature, were “extraordinary” and had implications for our understanding of the sensitivity of the globe to even tiny increases of carbon in the atmosphere.
Study co-author, Dr Helen Mc Gregor, from the University of Wollongong said: “The early onset of warming detected in this study indicates the earth’s climate did respond in a rapid and measurable way to even the small increase in carbon emissions during the start of the industrial age.” Abrams said the increase in atmospheric carbon between the onset of warming and the end of the 1800s was “small”, around 15 parts per million.
