Scientists said in the 70s that we were going into global chilling and then ice age do u still believe them?

Question

This is very well documented that scientist were in agreement that the earth was in a global chilling cycle and was heading into an ice age. Now 30 yrs later some of them are telling us that we are in a global warming cycle and headed for disaster dont you think their predictions in the 70s kinda hurts their credibility a little.

Answer 1

There is a real explanation to why scientists though that we were going into an ice age in the 70's. Coal particulates from coal burning power plants are similar to the ash clouds that volcanoes put out. Both reflect radiation. At the end of the 70's the Clean Air Act was passed reducing the amount of particulates put into the air. This started the warming trend again. In short cleaning the air caused more pronounced Global Warming.

Some scientist have suggested that we start putting particulates back in the air to stop the warming trend again.

Answer 2

global warming has always been a political issue, not a scientific one...

in the 70's, Maggie Thatcher was trying to break the coal miners union. The cooling trend from 1949 to 1972 was blamed on coal-fired electrical plants.

This was used to justify Britains move to nuclear powered plants.

The evidence shows that the carbon dioxide level in the atmosphere FOLLOWS the warming trend by about 400 years, which the warming trend follows the SUNSPOT cycle.

Right now, there is much press about how the sunspot cycle is interrupting cell phone, TV and radio signals...and guess what!!!???

higher temperatures!!!
More erratic weather patterns!!!

What Gore didnt do was show you his scale relative to geologic time where you could actually see this FACT.

Gore also forgets to tell you that there are many other "greenhouse" gasses..Carbon dioxide is measured in Parts per BILLION" and is only .05% of the atmosphere. Nitrogen is the largest gas next to oxygen, and you can actually see water vapor (clouds)

Keep in mind that Gore starts his lecture by introducing himself as a former future president of the US....sad
but it looks like he will do anything to try to get it back or get back..

(he signed the Kyoto treaty and fought for China have the exemption, the forgot to send it to Congress to be ratified)

Now some fresh pickings from the Political Grapevine:

Global Warming Beneficial?

A meteorology professor at the Massachusetts institute of Technology says there is no compelling evidence that global warming will lead to a catastrophe — and in fact might be beneficial.

Richard Lindzen writes in Newsweek: "Much of the alarm over climate change is based on ignorance of what is normal weather and climate. There is no evidence that extreme weather events are increasing…Indeed, meteorological theory holds that, outside the tropics, weather in a warming world should be less variable, which might be a good thing."

Lindzen says most of the current alarm over climate change is based on what he calls "inherently untrustworthy climate models, similar to those that cannot accurately forecast the weather a week from now."

Meanwhile, top hurricane forecaster William Gray of Colorado State University called Al Gore "a gross alarmist" during the closing speech of the National Hurricane Conference in New Orleans.

Gray says the recent increase in strong hurricanes is part of a natural cycle that has nothing to do with global warming. He says Gore is, "doing a great disservice and he doesn't know what he's talking about."

Answer 4

It's because this whole "chicken little" crowd doesn't understand the need to look at these cycles in the big picture.

There was a 40 year cooling trend, and these "scientists" looked at those 40 years and concluded that we were all going to die. Completely ignoring the millions of years and countless cycles that happened before it.

And then the cooling trend ended.. and they were left looking like idiots. So what did they do? They applied the same poor science to a SLIGHTLY longer timeframe.. and decided to tell everybody we're all going to roast to death.

But it's the same poor science backed by the same fools.. and it's just as baseless this time around as it was last time.

Answer 5

If you look at climate charts over the past million years, (instead of Gores 1000 year charts) created after the Vostok (Antarctic) ice core studies you will note 120,000 year warming/cooling cycles, now explained as the Milankovitch cycles, which are brought about by inconsistencies in earths orbit around the sun and varying polar tilt... as these warming cooling cycles manifest themselves, the Co2 content varies. several million years ago (when man was first dropping down out of the trees) the Co2 content was 10 times what it is today... Oh my..
There are those in power that, feeling their power slipping, need a crises to save us from.... It will cost money (ours) of course... Perfect timing, we are at a 120,000 year peak, temps are high, Co2 is high, and in the near (20,000 year) future we are going back into the cooling cycle...(again)...
: Don't believe everything you see, hear, and read... look at www.iceagenow.com. Who's right? Beware of a bunch of government funded chicken little’s with PHd's.... They create a reality based on dollar signs, not scientific notation.

Answer 6

the main ironic ingredient approximately that's that the premier concept interior the 70s replace into that the melting of the icecaps -- which had already been spoke of then -- could alter the climate in this sort of way that it could set off a sparkling ice age. That concept hasn't been completely abandoned, and in certainty it replace into the inspiration for the story line of the action picture, "The Day After day after today". curiously the deniers never afflicted to study any of the articles they brush aside so rapidly.

Answer 7

Scientists also used to believe that the world was flat and the the body's health was regulated by four humors. Just because they were wrong then doesn't mean we should stop listening to doctors and geographers today.

Answer 8

Not at all. Everything the scientists said about the cooling trend seen from the 1940's-70's was absolutely correct. The supposed 'hysteria' about it was propagated entirely by the media.

Answer 9

Scientists change their minds when presented with evidence that their old ideas were wrong, or that the present situation has changed from what it was in the past. I cannot say the same for some people on this forum though.
