Study: Man-made heat put in oceans has doubled since 1997

WASHINGTON (AP) -- The amount of man-made heat energy absorbed by the seas has doubled since 1997, a study released Monday showed.
Scientists have long known that more than 90 percent of the heat energy from man-made global warming goes into the world's oceans instead of the ground. And they've seen ocean heat content rise in recent years. But the new study, using ocean-observing data that goes back to the British research ship Challenger in the 1870s and including high-tech modern underwater monitors and computer models, tracked how much man-made heat has been buried in the oceans in the past 150 years.
The world's oceans absorbed approximately 150 zettajoules of energy from 1865 to 1997, and then absorbed about another 150 in the next 18 years, according to a study published Monday in the journal Nature Climate Change.
To put that in perspective, if you exploded one atomic bomb the size of the one that dropped on Hiroshima every second for a year, the total energy released would be 2 zettajoules. So since 1997, Earth's oceans have absorbed man-made heat energy equivalent to a Hiroshima-style bomb being exploded every second for 75 straight years.

(10,893 posts)I had not heard "zetta" before. A zetta is a sextillion, which is a billion trillion. Which is 1 followed by 21 zeros.

Annual global energy consumption is approximately 0.5 ZettaJoules.

(62,504 posts)yes, climate change is very important, but the absolutely most important part regarding CC is the warming of the oceans.
Krill supply roughly 1/2 of the oxygen we breath.
they die, we die.

(332 posts)One outside scientist, Kevin Trenberth, climate analysis chief at the National Center for Atmospheric Research, also has been looking at ocean heat content and he said his ongoing work shows the Gleckler team "significantly underestimates" how much heat the ocean has absorbed.

(59,578 posts)Since oceans make up about 70% of the planet's surface, plenty of area for the transfer.

(39,215 posts)about sewage runoff. Things like that. Many lakes have septic tank runoff from every house around them. In Iowa the cattle ponds the government paid for now have so much algae from cattle waste runoff.
Just wondered if there were little things we could change to help this situation.

(19,224 posts)It's like pouring a thimble of water into Lake Superior.
Excess heat generated by human activity isn't directly warming the planet to any appreciable degree.
Carbon in the atmosphere, put there by the burning of fossil fuels, and trapping SOLAR heat is what is to blame for 99.99999999% of the warmth seen so far.
I'm pretty sure that the "swimming" response was sarcasm in response
to the inevitable one-stop-shop reply from chernabog (who believes that
every problem in the world can be fixed by "stop eating meat" .
