Ocean Heat: New Study Shows Climate Scientists Can Still Torture Data until the Data Confess

A week or so ago, a troll left a link at my blog to a supposed-to-be-alarming blog post about a new climate study of ocean heat content. According to the study, a revised method of tweaking ocean heat reconstructions has … Continue reading

Yet Even More Nonsense from Grant Foster (Tamino) et al. on the Bias Adjustments in the New NOAA Pause-Buster Sea Surface Temperature Dataset

UPDATE: It was pointed out in a comment that the model-data comparison in the post was skewed. I was comparing modeled marine air temperature minus modeled sea surface temperature anomalies to observed night marine air temperature minus sea surface temperature … Continue reading

Fundamental Differences between the NOAA and UAH Global Temperature Updates

As you are well aware, there is a very basic difference between the updates to the NOAA and UAH global temperature datasets: the NOAA update increased the warming rate of their product during the slowdown in global surface warming, while … Continue reading

The Three Faces of the GISS Land-Ocean Temperature Index (LOTI)

This is the first of a series of posts about the impacts of NOAA’s new pause-buster sea surface temperature data on the global temperature products from GISS and NCEI (formerly NCDC). In this post, we’re going to compare the three … Continue reading

Both NOAA and GISS Have Switched to NOAA’s Unjustifiably Overcooked “Pause-Busting” Sea Surface Temperature Data for Their Global Temperature Products

This is the June 2015 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update, but in it we’re presenting the new GISS and NCEI surface temperature products…and the UAH lower troposphere temperature data version 6.

New Paper Calls into Question Reanalysis-Based and Climate Model-Based Explanations for the Slowdown in Global Surface Warming

INTRODUCTION The topic of this post is the paper Nieves et al. (2015) Recent hiatus caused by decadal shift in Indo-Pacific heating, which was embargoed until 2PM eastern today. The abstract reads (my boldface):
