Causes of differences in model and satellite tropospheric warming rates
The following article was published in Nature Geoscience on 6/19/17:
https://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo2973.html
Note the last sentence in the "Abstract":
"We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations."
This means that the computer models used to predict anthropologic global warming have systematically overstated the rise in global temperatures. This is a study submitted to peer review by a large group of scientists who previously have vigorously defended the models.

Thoughts on the Public Discourse over Climate Change
The link below will take you to an essay written by Richard Lindzen Alfred P. Sloan Professor of Meteorology, Department of Earth, Atmospheric and Planetary Sciences at Massachusetts Institute of Technology.
http://merionwest.com/2017/04/25/richard-lindzen-thoughts-on-the-public-discourse-over-climate-change/
His conclusion to this article is as follows:
"The system we are looking at consists in two turbulent fluids interacting with each other. They are on a rotating planet that is differentially heated by the sun. A vital constituent of the atmospheric component is water in the liquid, solid and vapor phases, and the changes in phase have vast energetic ramifications. The energy budget of this system involves the absorption and reemission of about 200 watts per square meter. Doubling CO2 involves a 2% perturbation to this budget. So do minor changes in clouds and other features, and such changes are common. In this complex multifactor system, what is the likelihood of the climate (which, itself, consists in many variables and not just globally averaged temperature anomaly) is controlled by this 2% perturbation in a single variable? Believing this is pretty close to believing in magic. Instead, you are told that it is believing in ‘science.’ Such a claim should be a tip-off that something is amiss. After all, science is a mode of inquiry rather than a belief structure."
