A new research brings new insights on global warming, climate change, and their probable future outcomes. According to the new findings, climate change is moving at a slower pace but it may soon start galloping again.
A team of scientists found that the main culprit for the current slow down in global warming which had been recorded since 1998 may be an oscillation in oceanic temperatures in the Pacific Ocean.
The Pacific Decadal Oscillation is an event very similar to El Niño-La Niña cycles, yet different since it occurs over the decades, rather than on a yearly scale. Scientists explained that the Pacific experienced lower surface temperatures brought in by its currents, while its depths remained warm.
“Cool Pacific temperatures have played a key role in modulating atmospheric temperature increases in the past 10 years, only partially offset by modest warming in the Atlantic,”
the authors of the study wrote in their paper.
According to the new study, the surface temperatures helped a lot our global climate conditions to relax a bit, putting global warming on the “pause” button. However, study authors think that the pause may be soon over since the oscillation is sharply reversing its current state towards a warming trend.
If that is the case, in the next decades humanity will not only see the effects of a further rising global warming, but it will also experience an acceleration of the process, since the increasingly warming oceans will add a lot to it, scientists suggest.
Two years ago, the Intergovernmental Panel on Climate Change (IPCC) issued a public report that informed the public that global warming was a on a stationary trend over the last decade. Back then, many climate change challengers focused only on this statement to back their theories further, according to which global warming is a hoax staged by occult forces for overly occult purposes.
But scientists, although puzzled by the announcement conducted several studies on the issue to learn the true causes behind the slow down. Some of them found that solar activity may somehow influence climate change trend on Earth, others argued that a boost in global volcanic activity may be responsible for the sudden stop. But the new study points the finger at oceans and their natural variations in their cooling activity.
Additionally, the recent study, which had been sent for publication last July, claimed that the pause may be already over, since the year 2014 was the hottest on the record according to The National Oceanic and Atmospheric Administration (NOAA).
