The Trouet Ocean Proxies

Apr 14, 2009 – 11:45 AM

Here are the ocean proxies used in Trouet et al. As usual in Team studies, it is a total mystery how they are selected. Trouet et al is a bit different from usual Team studies in that it argues for a MWP-LIA global reorganization, something that I’ll get to soon. Today, I want to chat […]

Another Oceanic MWP Proxy

Feb 20, 2007 – 1:59 PM

I’ve been going through the literature and data on ocean sediments looking for proxies with high resolution in the Holocene – something that I discussed a few months ago. Kim et al 2004 and Lorenz et al 2006, two articles by the same group, discuss Holocene SST changes based on alkenones. Most of their proxies […]

The Team versus Stott et al 2004

Jan 7, 2007 – 4:19 PM

The Team (at both realclimate and NOAA) have stated in the strongest possible terms that the Holocene Optimum was restricted to summer in the NH extratropics. Reviewing their positions, realclimate here The [Holocene Optimum] is a somewhat outdated term used to refer to a sub-interval of the Holocene period from 5000-7000 years ago during which […]

The MWP in the Warm Pool

Dec 27, 2006 – 10:12 PM

You may recall Hansen’s strange splice of modern instrumental records with a Mg/Ca SST proxy ending in 4320 BP based on a partially dissolved core.’ A couple of months ago, I mentioned a new paper by Newton et al (including L Stott) with a high Warm Pool MWP and briefly discussed Netwon’s presentation at AGU […]
