…When Sea Levels Were Roughly 20 to 30 Feet Higher than Today
Guest Post by Bob Tisdale
Science recently published Hoffman, et al. (2017) Regional and global sea-surface temperatures during the last interglaciation. Not too surprisingly, the study has been ignored by the mainstream media. Why? As Science writes in their summary (my boldface):
Sea surface temperatures of the past
Understanding how warm intervals affected sea level in the past is vital for projecting how human activities will affect it in the future. Hoffman et al. compiled estimates of sea surface temperatures during the last interglacial period, which lasted from about 129,000 to 116,000 years ago. The global mean annual values were ∼0.5°C warmer than they were 150 years ago and indistinguishable from the 1995–2014 mean. This is a sobering point, because sea levels during the last interglacial period were 6 to 9 m higher than they are now.
Of course, in very basic terms, that suggests today’s sea surface temperatures are still within the range of natural variability, contradicting climate model-based nonsense about current values, while sea levels still have a ways to go to catch up to the past.
The Abstract for Hoffman, et al. (2017) reads:
The last interglaciation (LIG, 129 to 116 thousand years ago) was the most recent time in Earth’s history when global mean sea level was substantially higher than it is at present. However, reconstructions of LIG global temperature remain uncertain, with estimates ranging from no significant difference to nearly 2°C warmer than present-day temperatures. Here we use a network of sea-surface temperature (SST) records to reconstruct spatiotemporal variability in regional and global SSTs during the LIG. Our results indicate that peak LIG global mean annual SSTs were 0.5 ± 0.3°C warmer than the climatological mean from 1870 to 1889 and indistinguishable from the 1995 to 2014 mean. LIG warming in the extratropical latitudes occurred in response to boreal insolation and the bipolar seesaw, whereas tropical SSTs were slightly cooler than the 1870 to 1889 mean in response to reduced mean annual insolation.
And as EurekaAlert! also notes about Hoffman, et al. (2017) in their article Sea-surface temps during last interglacial period like modern temps:
…Their analysis reveals that, at the onset of the LIG 129,000 years ago, the global ocean SST was already similar to the 1870-1889 average. However, by 125,000 years ago, the global SST increased by 0.5° ± 0.3°Celcius, reaching a temperature indistinguishable from the 1995-2014 average. These results suggest that LIG global mean annual SSTs simulated with most global climate models are too low…
Many thanks to blogger “Alec aka Daffy Duck” for the heads-up here.
Can’t be true. Doesn’t fit the narrative.
Every measurement has an uncertainty, a plus or minus of whatever. For example, a small reported climate temperature change of +0.1 degrees could well have an uncertainty of +/- 0.2 degrees. So the actual temperature change might be zero, or even negative.
It is obvious to me that the “climate change” folks are manipulating the data to suit their agenda. Why do I say that? Because the climate change folks will not allow any discussion or debate. They are hiding something! And that something is most likely a manipulation of the data.

I saw one article that claimed the models were just fine and this new result meant that a burst of warming was surely about to occur, so we must act to save the world, or sea levels would rise 9 meters very quickly, ….

And just like that “Global Warming Vanished” No mention of it on the white house.gov page. Praise God. This is the biggest leftist agenda being shoved down the American peoples throats and they try to make it believable or threaten us deniers. But that it the LIE, there is nothing to deny cause it was all made up by a bunch of power hungry people who thought they could fool the ignorant of America.. Haha.. I am one happy women and am so glad we will tap into OIL & GAS since it is so abundant and lowers the cost of energy on ALL Americans. AND JUST LIKE THAT, THEY WAS NO MORE CLIMATE CHANGE, WHICH THERE NEVER WERE. The earth has cycles and just cause it warms and cools at different times does not mean you can shove you money grubbing agenda down our throats. THANK GOD FOR TRUMP.. THE SILENT MAJORITY SPOKE AND IT ISN’T FOR DAMN CLIMATE CHANGE. Just that name is ridiculous. Duh of course the climate changes. Hello wake up, its a new day in America.
Some good charts in the comments....tou might find them interesting!
Larger things than these “scientists” can cram into their test tubes are the basis of long term climate changes. Not all the observable factors are pointing to the same putative future trends. This is a God-sized problem and it will never fit into a man-sized box.
Would the MSM bury this if it said the sea was ten degrees hotter?
We have been told by the media and climate “scientists” that the Earth's temperatures today are the highest ever since the dawn of time due to CO2 emitted from Ford Excursions drive by selfish, uncaring suburban moms.
Now they say it's been hotter as recently as 120,000 years ago.
Not a lot of Ford Excursions cruising around the last interglacial period.
Interglacial Period means a warm lull between successive periods periods of glacialization. This piece implies that the oceans temperatures during the subsequent glacial period were indistinguishable from out own?
The sea levels during the peak of the last glacial period where 125 meters below where they are today

You mean to tell me that the climate, the oceans and landmasses change over hundreds, thousands and millions of years? Huh. </shocked_face>
Gollee, I shore never wood a thunk o’ no sich as that ahapnin!
They are interesting, thanks, EatB!
Even a cursory glance at those charts shows that the temp.
of the planet is nowhere near either extreme nor is it
changing at anything that could be considered a rapid pace.
For the last 25 years there has been no measurable change.
But that’s like measuring hair growth for five seconds and
determining an average yearly rate of growth from that.
Global Warming/Climate Change is fake science based on
nonsensical interpretations of fake data. Period!
