just curious,, do you have anything on how its supposed to be?? maybe an instruction manual on whats supposed to happen to the earth over the yrs???
cause this could be normal,,,
It is quite normal, even wetter than it was a millennium ago.
Lordy, lordy, another dumb fuck.
"Catastrophic wildfires, decreasing snowpack and dwindling water resources have become a normal part of life for residents in the western U.S. And, as a result of
climate change, this may be just the beginning. A new study from Columbia University says the region has now entered into a climate-driven megadrought — possibly the worst in modern history.
Since 2000, the West has experienced one of its driest 20-year periods in history due to a combination of a dry natural cycle and the
changing climate. While there have been some wet years like in 2019, overall water resources have been under unprecedented stress in the modern era.
Going back over a thousand years, there's evidence that naturally driven megadroughts have devastated the region several times in history. These droughts led to upheavals among indigenous civilizations in the Southwest."
"We're on the same trajectory as the worst prehistoric droughts," the researchers say.

can you prove thats not just the normal progression of life on earth???
snow/glaciers has been melting since the peak of the ice age and wildfires have been a normal thing throughout history,,,
For the last 4000 years we have been in a cooling trend, driven by the Milankovich Cycles.

No Uptick in Marcott Thesis
March 14, 2013
Excerpt:
Reader ^ drew our attention to Marcott’s thesis (see chapter 4
here. Marcott’s thesis has a series of diagrams in an identical style as the Science article. The proxy datasets are identical.
However, as Jean S alertly observed, the diagrams in the thesis lack the closing uptick of the Science. Other aspects of the modern period also differ dramatically.
Here is Figure 1C of the Science article.
Now here is the corresponding diagram from the thesis (Figure 4.3a):

How Marcottian Upticks Arise
March 15, 2013
Excerpt:
I’m working towards a post on the effect of Marcott re-dating, but first I want to document some points on the methodology of Marcott et al 2013 and to remove some speculation on the Marcott upticks, which do not arise from any of the main speculations.
In the graphic below, I’ve plotted Marcott’s NHX reconstruction against an emulation (weighting by latitude and gridcell as described in script) using proxies with
published dates rather than Marcott dates. (I am using this version because it illustrates the uptick using Marcott methodology. Marcott re-dating is an important issue that I will return to.) The uptick in the emulation occurs in 2000 rather than 1940; the slight offset makes it discernible for sharp eyes below.

The Marcott-Shakun Dating Service
March 16, 2013
Excerpt:
Marcott, Shakun, Clark and Mix did not use the published dates for ocean cores, instead substituting their own dates. The validity of Marcott-Shakun re-dating will be discussed below, but first, to show that the re-dating “matters” (TM-climate science), here is a graph showing reconstructions using alkenones (31 of 73 proxies) in Marcott style, comparing the results with published dates (red) to results with Marcott-Shakun dates (black). As you see, there is a persistent decline in the alkenone reconstruction in the 20th century using published dates, but a 20th century increase using Marcott-Shakun dates. (It is taking all my will power not to make an obvious comment at this point.)

Hiding the Decline: MD01-2421
March 17, 2013
Excerpt:
As noted in my previous post, Marcott, Shakun, Clark and Mix disappeared two alkenone cores from the 1940 population, both of which were highly negative. In addition, they made some surprising additions to the 1940 population, including three cores whose coretops were dated by competent specialists 500-1000 years earlier.
While the article says that ages were recalibrated with CALIB6.0.1, the differences between CALIB6.0.1 and previous radiocarbon calibrations is
not material to the coretop dating issues being discussed here. Further, Marcott’s thesis used CALIB6.0.1, but had very different coretop dates. Marcott et al stated in their SI that “Core tops are assumed to be 1950 AD unless otherwise indicated in original publication”. This is not the procedure that I’ve observed in the data. Precisely what they’ve done is still unclear, but it’s something different.
In today’s post, I’ll examine their proxy #23, an alkenone series of Isono et al 2009. This series is a composite of a piston core (MD01-2421), a gravity core (KR02-06 St. A GC) and a box/multiple core (KR02-06 St A MC1), all taken at the same location. Piston cores are used for deep time, but lose the top portion of the core. Coretops of piston cores can be hundreds or even a few thousand years old. Box cores are shallow cores and the presently preferred technique for recovering up-to-date results.
There are vanishingly few alkenone series where there is a high-resolution box core accompanying Holocene data. Indeed, within the entire Marcott corpus of ocean cores, the MD01-241/KNR02-06 splice is unique in being dated nearly to the present. Its published end date was -41BP (1991AD). Convincing support for modern dating of the top part of the box core is the presence of a bomb spike:

A plot of this series is shown below, with the “present” value reported by Isono et al shown as a red dot.
