Pause Also Vanishes With Latest RSS Lower Troposphere Data

Warning: Numerology Ahead

Note Added 8:50 pm: This February data is for RSS TLT version 3.3, not the new version v4.0 (see below). The middle troposphere (TMT) and lower stratosphere (TLS) have both been updated to the new version 4.0, but the lower troposphere data (TLT) won't be updated for about six months, I was told.

The "pause" in lower troposphere data -- the one Ted Cruz was so passionate about -- also disappears with the latest RSS data for the lower troposphere.

They also found February 2016 to be the warmest month (compared to baseline) in their 37+ year record. Translated to a common baseline -- UAH's, Jan 1981 - Dec 2010 -- RSS's LT February anomaly is +0.88°C -- UAH's was 0.83°C.

Reminder: UAH and RSS don't quite measure the same thing, since RSS misses area around the poles -- 0.9% in the northern hemisphere, and 6.0% in the southern hemisphere. But this may change with their new version 4 (see below).

Andrew Dessler has a thought about this.

Even WUWT can't deny it, though it tries, of course.

By the way, Carl Mears and Frank Wentz of RSS have a new paper in J Climate, introducing their new dataset, version 4. (They properly published a paper when introducing their new version, unlike ______.) They write:
The new dataset shows substantially increased global-scale warming relative to the previous version of the dataset, particularly after 1998. The new dataset shows more warming than most other middle tropospheric data records constructed from the same set of satellites. We also show that the new dataset is consistent with long-term changes in total column water vapor over the tropical oceans, lending support to its long-term accuracy.
I'll try to get a copy of the paper and post some graphs from it. Tamino has the relevant graph.

For today's update, here is RSS's graph.:
