The effects of global warming on our oceans are equivalent to every second of a nuclear bomb blast for 150 seconds



An astonishing new study sheds new light on the multitude that has been plunged into the Earth's oceans for the past 1

50 years – the equivalent of a nuclear bomb blast that occurred every second for 150 years.

The study, published by researchers at the University of Oxford, shows that 90 percent of the heat captured by greenhouse gases since 1871 has been held by Earth's oceans, a revelation that is described as "worrying" and potentially large Has an impact on the climate.

"Most" The surplus energy stored in the climate system due to anthropogenic greenhouse gas emissions was absorbed by the oceans and led to thermal expansion and sea-level rise, "the study said." The oceans thus play an important role in the Earth's energy imbalance , Observational pressures on future human warming are critically dependent on accurate estimates of past changes in ocean heat content (OHC). "

Laure Zanna, the study's lead researcher, noted The Guardian calculated (a review independent of Fox News) that this equates to the discharge of 1.5 Hiroshima bombs per second.

"I'm not trying this kind of calculation Just because I find it disturbing. "Zanna told the news agency, but added that it is obvious that" we put too much energy into the climate system and many of them end up in the ocean. There is no doubt. "

The amount of energy absorbed by the oceans equals 1,000 times the total world population per year, Zanna told Weather.com.

In a research study, Samar accompanied Khatiwala, a professor at the Oxford University, who also worked on the study compared with the team's approach to painting.

"Our approach is akin to" painting "different areas of the sea surface with dyes of different colors and monitoring how they progress over time Khatiwala continued in the Deep Pacific (19459015).

Khatiwala continued, "If we know how high the sea surface temperature anomaly in 1870 is in the North Atlantic was, we can find out how much it contributes to the warming of the deep Indian Ocean in 2018. The idea goes back to the English mathematician George Green almost 200 years back. "

Over the past 60 years, researchers have found that the changes in ocean circulation are responsible for up to half of the warming and sea-level rise in the Atlantic.

to obtain man-made causes and the researchers said further investigation is needed to determine the cause.

Zanna noted, however, that the technique one sees is "just for tracers artificial carbon that is passively transported by the circulation of the ocean.
