Stips, Macias, Coughlan, Garcia-Gorriz, and Liang (2016) (Nature Scientific Reports) use information flows (Liang, 2008, 2014) to establish causality from various forcings to global temperature. We show that the formulas being used hinges on a simplifying assumption that is nearly always rejected by the data. We propose an adequate measure of information flow based on Vector Autoregressions, and find that most results in Stips et al. (2016) cannot be corroborated. Then, it is discussed which…

On the causal structure between CO2 and global temperature
TLDR
This study unambiguously shows one-way causality between the total Greenhouse Gases and GMTA, and confirmed that the former, especially CO2, are the main causal drivers of the recent warming.

TLDR
Based on a recently rigorized physical notion, namely, information flow, an inverse problem is solved and can one faithfully tell, in a rigorous and quantitative way, the cause and effect between them.
A Time-Varying Causality Formalism Based on the Liang–Kleeman Information Flow for Analyzing Directed Interactions in Nonstationary Climate Systems
The interaction between the land surface and the atmosphere is of significant importance in the climate system because it is a key driver of the exchanges of energy and water. Several important
Atmospheric Temperature and CO2: Hen-or-Egg Causality?
It is common knowledge that increasing CO2 concentration plays a major role in enhancement of the greenhouse effect and contributes to global warming. The purpose of this study is to complement the

TLDR
An unusually strong one-way causality is identified from IBM to GE in their early era, revealing an old story, which has almost faded into oblivion, about "Seven Dwarfs" competing with a giant for the mainframe computer market.
Quasi-experimental estimates of the transient climate response using observational data
The transient climate response (TCR) is the change in global mean temperature at the time of an exogenous doubling in atmospheric CO 2 concentration increasing at a rate of 1% per year. A problem
