Global warming never stopped in last hundred years : Study

Global warming has never stopped in the past hundred years , with maximum rate of change occurring after second World War, according to a study. It has been attributed to persistent increases in atmospheric greenhouses (GHGs), especially in CO2, since 1870,the beginning of the industrial Revolution. The upward trend in global mean surface temperature (GMST) slowed or even paused during the first decade of the twenty - first century, even though CO2 levels continued nearly 400 parts per million (ppm) in 2013.

The hiatus is often attributed to internal climate variability, external forcing, or both, involving an increase in aerosols in the stratosphere during the period 2000-2010.The phase saw Interdecadal pacific Oscillation (IPO) accompanying intensified trade winds, extensive heat uptake by the deep ocean or an extremely low number of sunspots during the latest solar activity cycle.
