No, they were not predicting an ice age.

What were climate scientists predicting in the 1970s?

The fact is that around 1970 there were 6 times as many scientists predicting a warming rather than a cooling planet.

Their papers showed that the growing amount of greenhouse gasses that humans were putting into the atmosphere would cause much greater warming – warming that would exert a much greater influence on global temperature than any possible natural or human-caused cooling effects.

What are the chances?

Figuring the odds of Earth’s global hot streak

First, the National Oceanic Atmospheric Administration calculates global average temperature going back to 1880. That’s 135 years. So if no other forces were in play and temperatures last year were totally at random, then the odds of 2014 being the warmest on record are 1 in 135. Not too high.

2014 Was The Hottest Year On Record Globally By Far

As the JMA graph shows, there has been no “hiatus” or “pause” in warming. In fact, there has not even been a slowdown. Yes, in JMA’s ranking of hottest years, 1998 is in (a distant) second place — but 1998 was an outlier as the graph shows. In fact, 1998 was boosted above the trendline by an unusual super-El Niño. It is usually the combination of the underlying long-term warming trend and the regional El Niño warming pattern that leads to new global temperature records.

What makes setting the record for hottest year in 2014 doubly impressive is that it occurred despite the fact we’re still waiting for the start of El Niño.

… 2014 Takes Aim At Hottest Year On Record

Last month was the warmest August since records began being kept in 1880, the National Oceanic and Atmospheric Administration (NOAA) reported Thursday. NOAA also projected out scenarios for the rest of the year making clear that 2014 is going to be one of the very hottest years on record — and possibly the hottest.
