Thanks for posting these devekopments .There’s a Canadian by the name of Patterson who in 2007 discovered by analyzing the sediments around coastal regions in the arctic ocean found that active sun spot solar cycles affected fish production. That drilling is only down about a mile and a half down and not into the base when the last ice cycle began. Which might provide a bio clue of the conditions which existed prior to the cycle change record . Also the steaming method being used might prevent getting biological samples of a given period as the antarctic icing developed.
If they find anything that upset the AGW narrative or modern archeological/geological dogma will we ever about it?
