Notice the Antarctic regions not previously studied down deep have warmed the most ... at the surface.
I circled the area that is still grey so it can be compared with the previous, larger grey area circled on the graphic below on the right.
Recently I pointed out that new Argo data indicate that the same thing (i.e., increased ocean water warming in the deeper layers of the ocean around Antarctica) is happening down there in the Southern Hemisphere, which was previously relatively unstudied.
I have been looking at the Argo databases which have filled in the former grey areas (shown in an earlier NASA graphic to the right ... the grey area is at the bottom around Antarctica).
Compare the graphic at the top of this post to the one on the right and you will see much less grey on the top one, the most recent one, and lots more red in the previously inadequately surveyed area in the vicinity of Antarctica.
The erratic red-line on the graph to the left (which I did and posted in the previous post in this series) is what I am working on updating with new Argo data, and it will likely fall in line with those other more uniform latitude lines.
Except that it should show higher temperature increase lines, according to the paper published in nature, and quoted in a prior post:
The global ocean stores more than 90% of the heat associated with observed greenhouse-gas-attributed global warming. Using satellite altimetry observations and a large suite of climate models, we conclude that observed estimates of 0–700 dbar global ocean warming since 1970 are likely biased low. (Nature, Quantifying underestimates of long-term upper-ocean warming)(The Phrase is Back: "Worse Than Previously Thought"). I am mixing the home-school, at work, and classroom types of endeavors with the NASA endeavors (they share data ... hence databases galore).
It's worse than we thought. Scientists may have hugely underestimated the extent of global warming because temperature readings from southern hemisphere seas were inaccurate. (The world is warming faster than we thought)
We know that the planet is getting warmer—but it turns out that it's happening faster than we thought. Turns out scientists have been underestimating warming increases because of inaccurate temperature recordings taken in the southern oceans. (Earth Has Been Getting Warmer Way Faster Than We Thought)
The oceans are warming faster than previously thought, according to a pair of new studies released this weekend and published in the scientific journal Natural Climate Change. This conclusion is largely due to enhanced information gathering in the southern oceans, which was limited in the past. The research teams compared previous ocean warming figures, based on the less complete data, with projections based on information they were able to obtain from more detailed studies. They found that from 1970 through 2004, increases in ocean temperatures exceeded those earlier figures.(Scientists Discover World’s Oceans Warming Faster Than Predicted)
It is uplifting to be able to know that we everyday people can use the free databases to minimize faith and trust by actually knowing things ourselves (The Pillars of Knowledge: Faith and Trust?).
