1. But...but...but...that's when scientists were predicting an new Ice Age!!!!!!111111

not

Stupid fucking deniers...

yup

[ND-Dem]

4. well, if the scientists were predicting a new ice age, why are you yelling about "deniers"?

[jpak]

5. Because they were not predicting an Ice Age - that is a conservative denier myth

http://journals.ametsoc.org/doi/abs/10.1175/2008BAMS2370.1

Ignorant deniers are such losers...

yup

[ND-Dem]

6. But actually, articles about global cooling were in the press in the 70s (I had a friend who took

them very seriously); that's a fact.

http://denisdutton.com/cooling_world.htm

J. Murray Mitchell showed as early as 1963 a multidecadal cooling since about 1940.[2] At a conference on climate change held in Boulder, Colorado in 1965, evidence supporting Milankovitch cycles triggered speculation on how the calculated small changes in sunlight might somehow trigger ice ages. In 1966 Cesare Emiliani predicted that "a new glaciation will begin within a few thousand years." In his 1968 book The Population Bomb, Paul R. Ehrlich wrote "The greenhouse effect is being enhanced now by the greatly increased level of carbon dioxide... [this] is being countered by low-level clouds generated by contrails, dust, and other contaminants... At the moment we cannot predict what the overall climatic results will be of our using the atmosphere as a garbage dump."[4]

Concern peaked in the early 1970s, though "the possibility of anthropogenic warming dominated the peer-reviewed literature even then" [2] (a cooling period began in 1945, and two decades of a cooling trend suggested a trough had been reached after several decades of warming). This peaking concern is partially attributable to the fact much less was then known about world climate and causes of ice ages. However, climate scientists were aware that predictions based on this trend were not possible - because the trend was poorly studied and not understood (for example see reference[12]). Despite that, in the popular press the possibility of cooling was reported generally without the caveats present in the scientific reports, and "unusually severe winters in Asia and parts of North America in 1972 and 1973...pushed the issue into the public consciousness".[2]

The general public gets its information from media. If you think people are so stupid, blame the media.

[jpak]

7. None of that was published in a peer reviewed paper - and deniers are still stupid

by definition

yup

[ND-Dem]

8. ordinary people get their news from media, not scientific papers. and in fact, some of it *was*

published in scientific journals.

[jpak]

9. Really? Which papers?

Do tell...

[ND-Dem]

10. here's one:

Atmospheric Carbon Dioxide and Aerosols: Effects of Large Increases on Global Climate

Abstract

Effects on the global temperature of large increases in carbon dioxide and aerosol densities in the atmosphere of Earth have been computed. It is found that, although the addition of carbon dioxide in the atmosphere does increase the surface temperature, the rate of temperature increase diminishes with increasing carbon dioxide in the atmosphere.

For aerosols, however, the net effect of increase in density is to reduce the surface temperature of Earth. Because of the exponential dependence of the backscattering, the rate of temperature decrease is augmented with increasing aerosol content. An increase by only a factor of 4 in global aerosol background concentration may be sufficient to reduce the surface temperature by as much as 3.5 ° K. If sustained over a period of several years, such a temperature decrease over the whole globe is believed to be sufficient to trigger an ice age.

11. LOL - reading comprehension much?

The paper was about forcing factors and did not "predict a New Ice Age" or "Global Warming" - just the effects of CO2 and aerosols considered separately.

[Dont call me Shirley]

2. So the fossil fuel industry owners and executives should be tried and imprisoned for crimes

against humanity and crimes against the earth.

[kpete]

3. that

works for me


peace,

[bananas]

13. And the nuclear industry - see post 12. nt

[bananas]

12. LBJ said "radioactive materials and a steady increase in carbon dioxide"

The "..." is "radioactive materials and"

Air pollution is no longer confined to isolated places. This generation has altered the composition of the atmosphere on a global scale through radioactive materials and a steady increase in carbon dioxide from the burning of fossil fuels. Entire regional airsheds, crop plant environments, and river basins are heavy with noxious materials. Motor vehicles and home heating plants, municipal dumps and factories continually hurl pollutants into the air we breathe. Each day almost 50,000 tons of unpleasant, and sometimes poisonous, sulfur dioxide are added to the atmosphere, and our automobiles produce almost 300,000 tons of other pollutants.

[Dont call me Shirley]

14. And those ruinous billionaires believe they can live in a bubble on mars or the moon to escape

the damage THEY themselves have caused. I shudder to think that those poisonous billionaires and their evil seed will be what is left to represent humanity!

[calimary]

15. Great find!

[BlancheSplanchnik]

16. geez

If only human nature wasn't so unintelligently designed.

[surrealAmerican]

17. He wasn't talking about climate.

He was talking about air pollution. The effects on climate were not understood at the time. There's no need to take this statement out of context. Pollution was an important issue at the time, especially in major cities.

[Scuba]

18. A distinction without a difference.

[surrealAmerican]

19. I'm afraid I can't agree with you there.

Even climate change deniers wouldn't dispute the existence of air pollution, nor the fact that it is caused by human activity. It's not the same thing.

[Scuba]

22. Oh dear.

[grahamhgreen]

20. Air pollution was considered CO, not CO2.

[loyalsister]

21. Thus the EPA was born- under Nixon

I vividly remember the talk of conservation in the 70s. And, during Jimmy Carter's presidency there was a lot of talk about alternative energy.

[rbrnmw]

23. LBJ will go down in history as one of the best

he was a no nonsense kind of guy.
