Prior to this inter glacial period there were no recordings of temperature or even ways of measuring temperature. Hence no way to compare. So his post has no merit in the first place. Most of his posts have no merit.
It is possible to estimate historical temperatures using materials trapped in ice. But I sympathise with your view.
They can go beck a few hundred thousand years with coral reefs - tell you what the temp of the Ocean was.
Antarctica leads the way in cooling. More Evidence Antarctica Has Been Cooling, Regional Sea Ice Increasing For Over 40 Years By Kenneth Richard on 27. September 2021 Share this... A new study (Kumar et al., 2021) reports the “overall SST trend in the Weddell Sea is negative” since 1979 and this has occurred in tandem with “the expansion of SIE [sea ice extent].” Another new study (King et al., 2021) reports the oldest temperature stations in Antarctica show a cooling/non-warming trend since 1956. Antarctica and the Southern Ocean sea ice extent surrounding it continue to defy the government-endorsed modeling that says “polar amplification” should dramatically amplify the global warming signal due to rising greenhouse gases . . .
Cooling is under way. Global Warming Of Past 40 Years An Artifact Of Pacific Ocean Cycle… Now Comes The Cooling By P Gosselin on 5. October 2021 Share this... The One Oscillation That Rules Them All By David Archibald Cumulative graphs, in which changes in the individual values from time period to time period are added, are powerful for showing changes of trend in a series. Thus the cumulative graph of the annual average solar aa Index (a geomagnetic index) nails the beginning and end of the Modern Warm Period: . . . .
No reason it can't. The amount of the greenhouse gases is the main cause, Insolation will not vary by a lot and even if it did that would only mean the heat would build up to the same temperature over more time
It says new colder period... and it's not happening since 2006. You do know we're going to the end of 2021 right?
My understanding has always been that global seal levels were lower during the last Ice Age, because so much water was locked up in the Continental Glaciers
That's not what that paper said. It said that Weddell Sea Ice went way up, and then crashed back down. Back in 1991, Dr. Suki Manabe, the father of global warming computer modeling, predicted that Antarctic sea ice levels would first increase, due to freshwater runoff from the continent making freezing easier, but would later decline, as warming ocean waters overwhelmed the freshening effect. That's what we see happening. So, another stunning success for AGW theory.
He didn't say the last ice age. He said "a few thousand". 2000 years ago is Roman era. Darn near everyone acknowledges that sea levels are now about 1.4 meters higher than they were in the Roman era.
Ten papers making that "crazy claim" (peer reviewed and published) are cited and linked in the post you quoted from.
Well, no. Antarctica has been cooling. More Evidence Antarctica Has Been Cooling, Regional Sea Ice Increasing For Over 40 Years By Kenneth Richard on 27. September 2021 A new study (Kumar et al., 2021) reports the “overall SST trend in the Weddell Sea is negative” since 1979 and this has occurred in tandem with “the expansion of SIE [sea ice extent].” Another new study (King et al., 2021) reports the oldest temperature stations in Antarctica show a cooling/non-warming trend since 1956. Antarctica […] Body Of Evidence: All Of Antarctica Is Cooling… Peninsula Cooling Since Long Before Greta Was Born By P Gosselin on 19. September 2021 The IPCC 6th Report seems to have missed a lot, hasn’t it? Recent publications since the 5th Report show ALL OF ANTARCTICA, including the peninsula, has cooled since the late 1990s. Friday I wrote about how the entire continent of Antarctica (except its peninsula) was found by leading scientists to be cooling significantly. The publication […] Scientists Find “Surprising” And “Statistically Significant” Cooling Trend Over Entire Continental Antarctica By P Gosselin on 17. September 2021 East Antarctica, which covers two thirds of the South Pole, has cooled a whopping 2.8°C over the past 4 decades; West Antarctica approximately 1.6°C. ..only tiny Antarctic Peninsula saw statistically insignificant warming. German climate website Die kalte Sonne posted its 64th climate video here and examined a new paper on Antarctica by Zhu et al […]
Explanation and links from the link (in post #1233) with the graph: ". . . Professor Ole Humlum, based in Svalbard near the Arctic Circle, has a trove of climate data at his website Climate4you. This includes a graphic of the cumulative graphic technique applied to the HadCRUT series of monthly global average surface air temperatures. It is found half way down this page, entitled ‘Cyclic air temperature changes’. . . ."
Point remains that the graph predicts that it's going to be colder after 2006. We have passed 2006 for 15 years now and guess what.... the prediction ends up to be untrue. It got warmer. We all know it has been getting warmer. It's not as if you can not find it. Get real. It says on wikipedia that the guy is a climate change denialist. And so that says it all. You're quoting an idiot. Case closed.
