When one theorizes about the Ice Ages of Glacial periods, when the maximum solar insulation is felt at the 65 north latitude, the greater energy would help melt snow and ice store on land in the higher northern latitudes. (Update: I must add that even the shift to maximum 65 north insolation is not always enough to end an "ice age".) Well there is more land mass in the northern hemisphere, so with more land benefiting from greater solar, what happens to the oceans that are now getting less solar? That is right sports fans, less ocean heat uptake. There is a northern to southern hemisphere "seesaw" because of the variation in the land to ocean ratio between the hemispheres.
So the Minions break out something like this Holocene temperature cartoon.
Then they wax all physics-acal about What's the Hottest Temperature the Earth's Been Lately moving into how the "unprecedented" rate of Ocean Heat Uptake is directly caused by their master the Great Carbon. Earth came from the word earth, dirt, soil, land etc. The oceans store energy a lot better than dirt.
NOAA Paleoclimate website. Based on this quick and dirty reconstruction, the oceans have been warming during the Holocene and now that the maximum solar insolation is in the southern hemisphere, lots more ocean area, the warming of the oceans should be reaching its upper limit. Over the next 11,000 years or so the situation will switch to minimum ocean heat uptake due to the solar precessional cycle. Pretty basic stuff.
With this reconstruction, instead of trying to split hairs, I just used the Mohtadi, M., et al. 2011.
Indo-Pacific Warm Pool 40KYr SST and d18Osw Reconstructions. which only has about 22 Holocene data points to create bins for the average of the other reconstructions, Marchitto, T.M., et al. 2010.
Baja California Holocene Mg/Ca SST Reconstruction, Stott 2004 Western Tropical Pacific and the two, Weldeab et al. 2005&6 equatorial eastern and western Atlantic reconstructions. There are plenty more to choose from so if you don't like my quick and dirty, go for it, do yer own. I did throw it together kinda quick so there may be a mistake or two, try to replicate.
I have been waiting for a while for a real scientist to do this a bit more "scientifically", but since it is raining outside, what the heck, might as well poke at a few of the minions.
Update: When Marcott et al. published their reconstruction they done good by providing a spread sheet with all the data. So this next phase is going to include more of the reconstructions used in Marcott et al. but with a twist. Since I am focusing on the tropical oceans, Mg/Ca (G. Ruber) proxies are like the greatest thing since sliced bread. Unfortunately not all of the reconstructions used extend back to the beginning of the Holocene. The ones that don't will need to be augmented with a similar recon is a similar area if possible or they are going to get the boot. So far these are the (G. Ruber) reconstructions I have on the spread sheet.
As you can start to see, the Holocene doesn't look quite the same in the tropics. There isn't a much temperature change and some parts of the ocean are warming throughout, or almost and some are cooling. The shorter reconstructions would tend to bump the end of the Holocene up which might not be the case. That is my reason for giving them the boot if there are others to help take they a bit further back in time. As for binning, I am going to try and shoot for 50 years if that doesn't require too much interpolation. Too much, is going to be up to my available time and how well my spread sheet wants to play. With 50 year binning I might be able to do 30 reconstructions without going freaking insane waiting for Open Office to save every time I change something. I know, there are much better ways to do things, but I am a programming dinosaur and proud of it.
