- Researchers analyzed findings from 88,125 studies published from 2012 to 2020.
- They found that less than 0.1 percent were skeptical of man-made climate change.
- That’s an increase from a 2013 study that found that three percent were skeptics.
- Team says it quashes any debate on human-caused climate change
Global warming is our fault, according to a new study that analyzed thousands of climate change papers, finding that more than 99.9 percent of them agree.
A total of 88,125 studies published from 2012 to 2020 were reviewed by experts from Cornell University in Ithaca, New York, to see how many of them linked human activity to the changing climate, and to look for consensus on the topic.
It is based on the work of a 2013 paper that analyzed all climate science papers published between 1991 and 2012, which found a 97 percent consensus.
“We are almost certain that the consensus is now over 99 percent,” said author Mark Linas, who said this is a ‘case closed’ for discussion of human-caused climate change.

Paris Agreement: Agreement to limit the rise in temperature
The Paris Agreement, first signed in 2015, is an international agreement to control and limit climate change.
It hopes to step up efforts to keep the increase in global mean temperature below 2 °C (3.6 °F) and limit temperature rise to 1.5 °C (2.7 °F).
It looks like the more ambitious goal of limiting global warming to 1.5 °C (2.7 °F) may be more important than ever, according to previous research, which claims that 25 percent of the world’s drought conditions will be significantly reduced. can see the increase.
The Paris Agreement on Climate Change has four main goals with respect to reducing emissions:
1) Long-term goal of keeping the increase in global mean temperature below 2°C above pre-industrial levels
2) Aim to limit the increase to 1.5 °C, as this will significantly reduce the risks and effects of climate change
3) Governments agreed on the need to peak global emissions as soon as possible, recognizing that this will take longer for developing countries
4) then sharply cut according to the best available science
The findings come as the UK prepares to host the COP26 climate change conference, where world leaders will discuss, and potentially set out, new legally binding agreements aimed at keeping global temperatures out of control.
The current Paris climate agreement, established at a United Nations conference five years ago, commits the world to actions that keep temperatures from rising more than 2.7 degrees Fahrenheit (1.5 degrees Celsius).
To better understand the state of global climate change among scientists rather than politicians or commentators, the team examined previous papers.
The US-led team began by examining a random sample of 3,000 studies from a dataset of 88,125 English-language climate papers published from 2012 to 2020.
They found that only four out of 3,000 papers cast doubt on human-caused climate change, or about 0.14 percent of those early papers.
‘We knew that’ [climate skeptical papers] They had disappeared in the case of the incident, but we thought there must be 88,000 more,” Linas said.
To find out whether there were more in the wider dataset, the study’s co-author, a UK software engineer Simon Perry, created a search algorithm.
It looked for keywords in papers that were commonly used by human-caused climate change skeptics, such as solar, cosmic rays and natural cycles.
The algorithm was applied to all 88,000-plus papers, and the program ordered them so that the skeptics came up with more in order.
He found many of these dissenting papers near the top, as expected, with diminishing returns further down the list.
In all, the search yielded 28 papers that were explicitly or explicitly suspicious, all published in minor journals.
Linas said, “If 97 percent of the 2013 study results still cast some doubt on the scientific consensus on human impact on climate, then the current findings go even further to remove any uncertainty, should it be the final word.” “
“It is important to acknowledge the major role greenhouse gas emissions play so that we can rapidly develop new solutions,” said co-author Benjamin Hulton.
“We are already seeing the devastating effects of climate-related disasters on businesses, people and the economy in real time,” he said.
Despite such results, opinion polls as well as the opinions of politicians and public representatives point to false beliefs and claim that ‘there still exists a significant debate among scientists on the true cause of climate change,’ He found
In 2016, the Pew Research Center found that only 27 percent of American adults believed that ‘almost all’ scientists agreed that climate change is due to human activity.

A 2021 Gallup poll pointed to a deeply partisan divide in American politics over whether the Earth’s rising temperature since the Industrial Revolution was primarily due to humans.
‘To understand where the consensus exists, you have to be able to quantify it,’ Linas said.
‘This means surveying the literature in a coherent and non-arbitrary way to avoid the trade-off of cherry-picked papers, which is often how these arguments are made in the public domain.’
The findings have been published in the journal environmental research paper.
