Why did left wing pseudoscientists spend 20 years warning about global cooling, now pseudoscientists are warning of global warming?

Question

and saying anyone who doesn't believe them this time is an ignorant moron?

Time Magazine Goes Both Ways On The Polar Vortex: ‘In 1974, Time Mag blamed the cold polar vortex on global cooling’ — In 2014: ‘Time Magazine blames the cold polar vortex on global warming’
'Scientists have found other indications of global cooling. For one thing there has been a noticeable expansion of the great belt of dry, high-altitude polar winds —the so-called circumpolar vortex—that sweep from west to east around the top and bottom of the world.'

Answer 1

A survey of peer reviewed scientific papers from 1965 to 1979 show that few papers predicted global cooling (7 in total). Significantly more papers (42 in total) predicted global warming (Peterson 2008). The large majority of climate research in the 1970s predicted the Earth would warm as a consequence of CO2. Rather than 1970s scientists predicting cooling, the opposite is the case.



So global cooling predictions in the 70s amounted to media and a handful of peer reviewed studies. The small number of papers predicting cooling were outweighed by a much greater number of papers predicting global warming due to the warming effect of rising CO2. Today, an avalanche of peer reviewed studies and overwhelming scientific consensus endorse man-made global warming. To compare cooling predictions in the 70s to the current situation is both inappropriate and misleading. Additionally, we reduced the SO2 emissions which were causing global cooling. The question remains whether we will reduce the CO2 emissions causing global warming.

Thank you for your question and this opportunity to share this recent Letter To The Editor which recently appeared on our local paper.



There has been no global warming sine the year 1998



Editor:

Government scientists have downgraded the global warming catastrophe to climate change. His Royal Highness of Wales stated that we have only until 2017 to save the world. Mr. Millionaire Al Gore's prediction was the year 2006.



I am not a climate denier but a climate changer. Climate changes constantly and whether or not I use more or less carbon won't solve this phenomenon. Our leader who could not even handle the administration of a health insurance website is very unlikely to be able to heal the planet.



This fact is that there has been no global warming since 1998, stated by scientists all over the world.



The media ignore the truth.



This tells us that it is a fraud perpetrated on the masses to line the pockets of evil men.

Answer 3

Their bread and butter are all those billions of dollars worth in government grants. If they ever stopped scaring the taxpayer about the next global climate disaster, that gravy train of theirs would grind to a halt and they'd be out of a job.

Answer 4

They failed with Global Warming just like they failed with the Aids Scare

Answer 5

It's all ********.I mean come on.This is all about a money grab.Global population will kill us off well before Global warming ever would.

Answer 6

When the money starts to dry up they will switch to the other side and resume the scare.

Answer 7

This is a silly argument. Science evolves. Terms change. When you get sick does the doctor tell you your "humors are out of balance," or that you have an infection? Do you study "Transmutation of the Species," or evolution?

Answer 8

technology wasn't advanced in 1970s compared to today.



but yes, the 1970s was a cool period.

Answer 9

They were liars like Gore and Obama.

Answer 10

Government research money.

Answer 11

They're all a buch of gays.
