If "Fact Briefs" ring a bell you are correct; we published 16 fact briefs a few years ago in collaboration with Repustar. We're happy to announce our restarting the creation of fact briefs together with Gigafact, a nonprofit equipping newsrooms to counter misinformation and protect the democratic process. The technology solution and concepts for Gigafact were actually incubated and tested within Repustar before becoming its own entity.
Our plan is to leverage the work we've been doing in the course of the ongoing rebuttal update project by creating fact briefs for already updated rebuttals, which now feature new at-a-glance sections. We'll also check if any of the already available fact briefs need updates, and include them in the weekly fact brief publications. One challenge will be to reword our myth titles to a question which can be answered with either "Yes" or "No". But even more daunting is the restriction that a fact brief can only have 150 words! It'll be interesting to see how that will work out— especially for some of the quite involved rebuttals we have out there!
Gigafact also offers two neat functionalities we plan to explore: a Tipline where items in need of some debunking can be suggested, and a Quiz where fact briefs and their answers are utilized in short quizzes with a few questions each.
We will publish one fact brief per week - most likely on Saturdays - and will also share them on our various social media channels. So, please keep an eye out and feel free to like and share them as you come across any of our fact briefs!
Skeptical Science is partnering with Gigafact to produce fact briefs — bite-sized fact checks of trending claims. This fact brief was written by Sue Bin Park in collaboration with members from our Skeptical Science team. You can submit claims you think need checking via the tipline.
Most peer-reviewed climate science papers published from 1965-1979 predicted global warming, not cooling.
While many popular media outlets claimed the approach of an ice age, a 2008 review of 1960s-70s climate science papers found that research stated otherwise. 62% predicted warming, 10% predicted cooling, and 28% did not take a stance.
There had been some notably cold Northern Hemisphere winters through this time. Scientists now understand that a leading cause of the cold conditions was aerosol smog pollution. Aerosols block sunshine, reducing the amount of energy reaching Earth's surface. They are also a serious health hazard. When they were reduced through regulation, global temperatures resumed their climb, from the 1970s onwards.
This decline is driven by increasing global temperatures from human-generated greenhouse gas emissions. While a 2017 study suggested that between 30% and 50% of the observed melting is due to natural causes, one of its authors stated that “anthropogenic forcing is still dominant,” whereas “natural variability...helped accelerate this melting.”
Today, 97% of climate scientists agree that global warming is real and largely caused by human carbon dioxide emissions.

About fact briefs published on Gigafact
Fact briefs are short, credibly sourced summaries that offer “yes/no” answers in response to claims found online. They rely on publicly available, often primary source data and documents. Fact briefs are created by contributors to Gigafact — a nonprofit project looking to expand participation in fact-checking and protect the democratic process.
