Dating industrial revolution

But even this raised the temperature by a few tenths of a degree.

The increase since 1900 has been more than 100 parts per million.

The southern hemisphere was around 50 years behind.

' 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).In a paleoclimatological first, Abram’s study incorporated not only land based sources like tree rings, but measured marine temperatures as well.The scientists found the land of the northern hemisphere and seas of the tropics began warming at roughly the same speed around 1830.The findings shift our understanding of exactly what is normal, because instrumental records of the global temperature only reliably go back as far as 1880.Using that baseline, Nasa has determined that the first six months of 2016 were 1.3C warmer than normal.Just as the dot-coms were integral to the 1990s, inventions were what made this epoch unique.Without all those soaring, ingenious minds, many of the basic goods and services we use today wouldn't exist.It was around this moment, scientists have discovered, that our own planet began to go off the rails.Using 2,000 years of paleoclimate data – the earth’s historical temperature measured from natural sources such as the growth bands of corals and trees, ice cores and the amount of pollen trapped in sediment layers – a global team of researchers lead by Australian National University associate professor Nerilie Abram, have pinpointed the moment when the earth’s temperature began to rise because of human greenhouse gas emissions to between 18.
