By the 1970s there was a growing consensus among climatologists that the earth would trend toward warming. And golly-gee......the earth has warmed considerably since then.

Most cited is a 1975 Newsweek article The Cooling World that suggested cooling "may portend a drastic decline for food production":
A 1974 Times Magazine article Another Ice Age? painted a similarly bleak picture:"Meteorologists disagree about the cause and extent of the cooling trend… But they are almost unanimous in the view that the trend will reduce agricultural productivity for the rest of the century."
However, these are media articles, not peer reviewed scientific papers. Does a consensus on global cooling emerge from the scientific literature?"When meteorologists take an average of temperatures around the globe, they find that the atmosphere has been growing gradually cooler for the past three decades. The trend shows no indication of reversing. Climatological Cassandras are becoming increasingly apprehensive, for the weather aberrations they are studying may be the harbinger of another ice age."
Over time, William Connelly has been steadily documenting 70s research predicting global cooling. It's a rich resource but as he admits, could be more accessible. Now he has collaborated with Thomas Peterson and John Fleck to publish The Myth of the 1970's Global Cooling Scientific Consensus, due to be published in the Bulletin of the American Meteorological Society.
The paper surveys climate studies from 1965 to 1979 (and in a refreshing change to other similar surveys, lists all the papers). They find very few papers (7 in total) predict global cooling. This isn't surprising. What surprises is that even in the 1970s, on the back of 3 decades of cooling, more papers (42 in total) predict global warming due to CO2 than cooling.
So in fact, the large majority of climate research in the 1970s predicted the Earth would warm as a consequence of CO2. Rather than climate science predicting cooling, the opposite is the case. Most interesting about Peterson's paper is not the debunking of an already well debunked skeptic argument but a succinct history of climate science over the 20th century, describing how scientists from different fields gradually pieced together their diverse findings into a more unified picture of how climate operates. A must read paper.
That's not how it works with GrossDad.How am I wrong? Prove it.
The scientific consensus to which you are referring never existed. If it did, as you claim, you need to prove it.
Some things are simply beyond current science and the limited science is being manipulated to drive a political agenda through a campaign of mis-information and scare tactics. You have little kids living in fear that the planet is going to burn up in their lifetimes because of the indoctrination they are receiving.Science is open ended and fallible.
Therefore, climate change due to humans is fake news.
Still not a scientific consensus, words have meanings.Bullshit. Was the media or was it not being alarmist over an ice age in the mid 70s? They were using claims from scientists to sound the alarm.....were they not. Just stop it. You look foolish.

What political agenda?Some things are simply beyond current science and the limited science is being manipulated to drive a political agenda through a campaign of mis-information and scare tactics.

Is that the same sperg that sailed across the Atlantic for show and then flew home?Some autistic 16 year old aryan girl just told the UN that we are facing a “mass extinction” if we “fail to act”.
can someone explain to me how a 3 degree change in global average temps over the next century will result in a mass extinction?
Maybe you haven't heard of this new thing.can someone explain to me how a 3 degree change in global average temps over the next century will result in a mass extinction?
Nice.sperg
Yes. And necessitated 3 or 4 other flights for people who had to bring the boat back.Is that the same sperg that sailed across the Atlantic for show and then flew home?
I don't know, but I'm kind of hoping this is the case.can someone explain to me how a 3 degree change in global average temps over the next century will result in a mass extinction?
Mass extinctions are a thing. And they're often caused by warming events.Some autistic 16 year old aryan girl just told the UN that we are facing a “mass extinction” if we “fail to act”.
can someone explain to me how a 3 degree change in global average temps over the next century will result in a mass extinction?
what caused the warming back then?Mass extinctions are a thing. And they're often caused by warming events.
Biggest mass extinction caused by global warming leaving ocean animals gasping for breath
The largest extinction in Earth's history marked the end of the Permian period, some 252 million years ago. Long before dinosaurs, our planet was populated with plants and animals that were mostly obliterated after a series of massive volcanic eruptions in Siberia.phys.org
