What scientists were really saying about “global cooling” in the 1970s

I remember hearing it too, back in the 1970s: “We’re heading into another ice age.”

Today we hear: “Why should we believe the climate scientists when they predict global warming? Back in the 1970s, they predicted the Earth’s climate was going to get much colder.”

But was “global cooling” really the consensus back in the 70s? The RealClimate blog reports:

During the period we analyzed, climate science was very different from what you see today. There was far less integration among the various sub-disciplines that make up the enterprise. Remote sensing, integrated global data collection and modeling were all in their infancy. But our analysis nevertheless showed clear trends in the focus and conclusions the researchers were making. Between 1965 and 1979 we found (see table 1 for details):

  • 7 articles predicting cooling
  • 44 predicting warming
  • 20 that were neutral

In other words, during the 1970s, when some would have you believe scientists were predicting a coming ice age, they were doing no such thing. The dominant view, even then, was that increasing levels of greenhouse gases were likely to dominate any changes we might see in climate on human time scales.

This was also reported in USA Today: Study debunks ‘global cooling’ concern of ’70s.

Christ-less Christianity

If I could pass on just one thing about Christianity and the gospel to my children, students at BCA, and church, it would be this: The gospel is all about Jesus Christ and what he has done for us in his incarnation, life, death and resurrection; not about what we do for him. You wouldn’t always know this, however, by reading many of the best-sellers in Christian bookstores, or by listening to the self-help sermons that are preached in many churches.

Michael Spencer — the Internet Monk — writes about this in his post No Jesus Needed:

Recently I listened to a sermon. Preached by a Christian, a Baptist, a minister at a church, a graduate of a Christian school training ministers to serve and communicate Jesus.

This preacher gave a message that he had worked hard to prepare; a message he had presented before. A message he deeply believed in.

It was a message well organized, passionately delivered and completely sincere. It was a message with an application about having a purpose in living that many people need to hear.

So why am I writing about that sermon? Did it change my life?

I’m writing about that sermon because it was a perfect illustration of Christless preaching.

There was not a single mention of Jesus. Not once. Not in any way. Nowhere.

It was as if Jesus had never been born. It was as if Jesus never existed.
