Experts Say Global Warming Hiatus Is Ending: What Are The Signs?


A new paper released by the U.K. Met Office on Sept.14 has reported that global warming hiatus is ending. As per climate pattern alterations and temperature records, the pause in the slow trend of temperature increase may soon take a bow, as evidenced by two environmental signs.

The United Nations released a report in 2013 that presented observations pertaining to the slower decelerating rate of temperature increases starting in 1998, compared with how it was 50 years before.

Now in a newly released report, experts from the Met Office said that according to the climate trends in both the Atlantic and Pacific oceans, together with global temperature records and almost record-high data obtained and projected in 2015 and for 2016, respectively, a significant shift is predicted.

With the impact of continuous carbon dioxide increases as well as the consistent trends of natural oceans, the climate is most likely to be in for a series of interesting changes.

"All of these signals are consistent with what we would expect to see at the end of the slowdown," said Adam Scaife, co-author of the report from the Met Office.

According to the paper, which was peer-reviewed by Professor Rowan Sutton from the University of Reading, the signs that suggest the stoppage of the global warming hiatus can be observed in the Pacific Ocean.

The first one is the occurrence of El Niño, which is characterized by the reversal of natural occurrences as the Pacific current shifts after about five years, on average. Under this phenomenon, regions that commonly suffer from drought receive heavy rain downpours and vice-versa. In general, El Niño drives temperatures to rise.

The second sign is the change in the temperature trends over the decades in the North Pacific. This region has been experiencing a "cool" phase, which is something the Met Office experts regard as a contributory factor in the hiatus of average surface temperature increases when decade trends are considered. However, the region is approaching a "warm" phase now, which will warm the world all the more.

The majority of these events can develop even without human activity, but given that humans are involved, when they do occur, notable environmental changes unfold and these little bits are the ones that create a record, said Scaife.
