All Scientists are Sceptics ~Professor Bob Carter

Whenever someone asserts that a scientific question is “settled,” they tell me immediately that they don’t understand the first thing about science. Science is never settled. Dr David Deming

Perhaps the most frustrating aspect of the science of climate change is the lack of any real substance in attempts to justify the hypothesis ~Professor Stewart Franks

In the 70s, Global Temps were going down and an Ice Age was predicted

UNSkeptical UNScience (SS) and their amazingly incorrect list of "myths."  Here we debunk No 11.

"Ice age predicted in the 70s"The vast majority of climate papers in the 1970s predicted warming.

SS adds in their link:
In the thirty years leading up to the 1970s, available temperature recordings suggested that there was a cooling trend.
Who are they trying to fool? Of course temperatures were cooling. They were cooling then as they are cooling now.

Here are the data from mid 50s to the mid 70s from GISS, NCDC and HadCRUT4. All three show a definite cooling. (Graphs from Prof Humlum's Climate4You)

Diagrams showing HadCRUT4, GISS, and NCDC monthly global surface air temperature estimates (blue) and the monthly atmospheric CO2 content (red) according to the Mauna Loa Observatory, Hawaii. The Mauna Loa data series begins in March 1958, and 1958 was therefore chosen as starting year for the diagrams. Reconstructions of past atmospheric CO2 concentrations (before 1958) are not incorporated in this diagram, as such past CO2 values are derived by other means (ice cores, stomata, or older measurements using different methodology), and therefore are not directly comparable with direct atmospheric measurements. The dotted grey line indicates the approximate linear temperature trend, and the boxes in the lower part of the diagram indicate the relation between atmospheric CO2 and global surface air temperature, negative or positive

Anthony Cox comments:

Ice age predicted in the 70s. Sure was, and everyone, scientists, politicians and the media were predicting it.

Every major climate organisation endorsed the ice age scare, including NCAR, CRU, NAS, NASA – as did the CIA.
