Massive Tampering With Temperatures In South America

One of the regions that has contributed to GISS’ “hottest ever year” is South America, particularly Brazil, Paraguay and the northern part of Argentina. In reality, much of this is fabricated, as they have no stations anywhere near much of this area, as NOAA show below.

Nevertheless, there does appear to be a warm patch covering Paraguay and its close environs. However, when we look more closely, we find things are not quite as they seem.

There are just three genuinely rural stations in Paraguay that are currently operating – Puerto Casado, Mariscal and San Juan. They all show a clear and steady upward trend since the 1950’s, with 2014 at the top, for instance at Puerto Casada:

It could not be more clearcut, could it? However, it all looks a bit too convenient, so I thought I would check out the raw data (which is only available up to 2011 on the GISS site, so the last three years cannot be compared). Lo and behold!

As we so often see, the past has been cooled.

GHCN show the extent to which they have adjusted temperatures, the best part of 2 degree centigrade.

Of course, there may be a genuine problem with Puerto Casada’s record, except that we see exactly the same thing happening at the other two Paraguayan sites.

So we find that a large chunk of Gavin’s hottest year is centred around a large chunk of South America, where there is little actual data, and where the data that does exist has been adjusted out of all relation to reality.

Even by GHCN standards, this tampering takes some beating.
