A 3C rise in temperature is just a 1% energy rise
With no phase changes the energy content of the air is proportional to its temperature. Earth's pre-industrial average temperature is 15C. Under a high estimate for CO2 warming of 3C the final temperature is 18C. Convert to absolute temperature and the difference is just 1.04%:
(273 + 18) - (273 + 15) / (273 + 15) = 1.04%
Warmists don't like facts laid bare like this (_1, _2). 1% is not enough to notice any difference in any climate metric such as hurricanes or tornadoes. Instead they insist on expressing the energy increase in joules or Hiroshima atomic bomb equivalent. This is more useful for their scare narrative. But when this energy is spread out over a large area it's nothing. This is why warmists hate the percentage value.

Has the hockey schtick left the building?
Unfortunately we may never know the real identity of who the hockey schtick is. They have protected their anonymity well. And no blame there. Why would't you protect your anonymity online? You have every right to. The only thing I can gather from their blog is that their initials are "MS". But who knows if that's even valid?
Hockey Schtick appears to be a chemical engineer by trade who last blogged on Feb 4 2017. Lately their twitter feed appears to have been hacked.

New improved Australia RSS TLT satellite temperature
More RSS TLT temps
It's often said there's a lot of warming in the North Atlantic & surrounding land stations so let us check there first with the RSS TLT temps in a square as depicted in the following map:

There is some warming in excess of the global average. It looks similar to the temps for North latitudes 21.25 N to 36.25 N (see graphs further down). In red is the code for Matlab R2016a.

RSS satellite temperature for Australia/Pacific
Below are RSS satellite
temperatures for various regions in Australia/Pacific. In a previous post (here) I
derived lower tropospheric temp for Australia in a rectangle shown in the map
below.

In this post I define a smaller
rectangle (red) to avoid any ocean areas, between longitudes 123.75 E to 146.25 E and
latitudes 31.25 South to 21.25 South.

RSS temp anomaly for Australia corrected for longitude
I've discovered a mistake in my first attempt at unlocking the RSS temperature file for lower tropospheric
temps: my longitude was off by 180 degrees.
Some time around that first attempt I took the time to
verify the latitude (described here) but not the longitude. I discovered my
mistake when I decided to verify the longitude for an upcoming post. Here is how
the latitude and longitude numbers in the 144 x 72 x 458 array should look on a world map:

Preview of upcoming "summary" rebuttal
My recent post on OLR is the hopefully the final preliminary post in preparation for a ~13-point rebuttal I plan to the AGW theory. Here's an outline of those points. I give a couple of links with each point to further explain.
It's interesting to see how far my thinking has evolved since my first attempt at a similar summary 7 years ago.

Outgoing Longwave Radiation – the fuller story
For a couple of years or so I have been claiming [1, 2] that outgoing longwave radiation (OLR) should be decreasing if infrared was being curtailed by increasing levels of carbon dioxide in the atmosphere as per AGW theory. But there is more to the story.
On a spectral line near 700 wavenumber (14.3 µm) there is indeed quite a reduction in radiation expected to be caused by an increase in CO2.
The following chart (data via the Modtran simulator) shows a deepening of the groove that appears around 700 to 770 wavenumber with surface temperature kept constant and atmospheric carbon dioxide increased from 150 to 1000 ppm.

How to load .nc files into Matlab
Much climate data comes in the form of NetCDF files which have an .nc suffix.
This post is as much for my own reference in case I forget how to do it, as it is for anyone else interested in opening a NetCDF file in Matlab.
Here's a list of the current climate NetCDF files I am interested in:
- · Satellite Temperature Lower Troposphere
↳
↳
(Note that the name suffix changes slightly with each month)
- NCEP Reanalysis 2 of Upward longwave radiation flux at nominal top of atmosphere

Circular axis unfairly weights more recent years
In the latest deception by Team Consensus, Ed Hawkins converts temperatures that are normally displayed on an X-Y plane to a circular axis.
This has the effect of increasing the area occupied by recent years and cramming past years into a little dot in the middle. The resulting spiral, made scarier by employing a violet to red rainbow colour, gives the impression of an out of control temperature rise.
