Lower atmospheric CO2 equals hotter. So says this paper about the hottest part of the last thousand years:
The MWP in a Multi Proxy Record of Argentinas Laguna Nassau (23 December 2015)
Another temperature reconstruction of the past millennium suggests that the warmest interval of the period occurred at a time when the air’s CO2 content was at its very lowest level…
Wasn’t low CO2 supposed to cause warming? The Greenies keep telling me that. But now NASA says they got it wrong all these more recent years. More CO2 causes cooling. Can’t make up their mind, can they. NASA Recycling The 1970’s Ice Age Scare
Gavin has a new paper out explaining the cause of the hiatus (which he also just erased.) He says that burning fossil fuels is generating aerosols which are suppressing global warming.
“TCR is characteristic of short-term predictions, up to a century out, while ECS looks centuries further into the future, when the entire climate system has reached equilibrium and temperatures have stabilised.”
This is the identical argument which climate scientists used in their last ice age scare of the 1970’s – during Watergate.
Gavin Schmidt? Again? The false prophet.
