GRACE satellite Greenland data is too negative-biased

Despite the DMI institute showing quite a mass gain for Greenland in 2016:

..The GRACE satellite data showed a continued mass decline.

BoM uptweaking Australia's average temperature to suit global warming narrative

Below is my derived RSS satellite temperature for Australia in the following rectangle:

New improved Australia RSS TLT satellite temperature

In my first attempt at this I got the longitude wrong (details here). Having corrected that, in my second attempt I defined a smaller rectangle to avoid any ocean areas as shown in the graph that follows.



...which yields the graph (16-point moving average in red):

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.

1) No temperature rise during time of highest CO2 rise also known as "the hiatus" in warming

(Links: One, Two, Three)

2) Lower stratosphere is not cooling

(Link: One)

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:

Why the "missing heat" of AGW can't be going in the ocean

The reason "missing heat" can't be going in the ocean is that the ocean is warming. A warmer ocean makes it less likely that heat will be drawn in from the atmosphere, not more.

Here is the global sea surface temperature anomaly, and it's on the rise:

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.

My reply:

Recent uptick in AGW concern epitomises ignorance of fears

The recent uptick in polls of the public's concern of AGW epitomise the public's ignorance regarding AGW (and frankly most issues scientific or technical).

AGW water-vapour-feedback theory disproved by satellite observations

AGW theory says that CO2 can cause some warming, for example 1C for a doubling of CO2; but that the resulting water vapour feedback will cause an extra 2C or so of warming, which is where the real AGW danger comes from. (Scared yet?)

Climate models [1, 2, 3] and observations show that each 1C of warming causes about a 7% increase in water vapour, which in turn causes a further 2C of warming.

Well, water vapour did just increase by about 7% over course of the year of 2015, but little happened to earth's average temperature; maybe a 0.2C warming at most over the same period:
