Climate Denial's Death Knell

A new survey conducted by a team of volunteers at Skeptical Science has definitively confirmed the scientific consensus in climate science literature -97 percent of peer-reviewed papers agree that global warming is happening and human activities are responsible.

Climate research nearly unanimous

Of more than 4,000 academic papers published over 20 years, 97.1% agreed that climate change is anthropogenic.

Consensus study

Research suggests support for climate change action increases if the public is aware of a scientific consensus on the evidence for human causes. But how many scientists really agree? A new study, out today, shows very few studies reject that climate change is human caused, and hopes to promote this message by encouraging the public to get involved. 

A team of volunteers from climate science blog,Skeptical Science, rated the abstracts of nearly 12,000 peer-reviewed papers based on their level of agreement that climate change is human caused. The new study aims to identify the level of consensus by analysing 20 years of climate change literature.

Is the science settled?

A group of volunteers have given up their time over the last few years to answer the question, once and for all, as to whether the "science is settled".

It's official! Humans caused global warming.

A comprehensive analysis of 4,000 studies on climate change published over last 21 years has revealed an overwhelming consensus among climate scientists that humans are to blame for global warming, researchers claim.

Global warming consensus: We can haz it!

The issue at hand is this: What is the level of agreement in the scientific community about the reality of climate change and about the human role in climate change? The new paper, Quantifying the consensus on anthropogenic global warming in the scientific literature, address this question and the answer is very clear. The number of climate scientists who question the reality of global warming or the human role in global warming is vanishingly small.

Largest study of peer-reviewed literature to date

A new peer-reviewed study has confirmed again that there is an overwhelming consensus on the human-driven cause of climate disruption. The study, Quantifying the consensus on anthropogenic global warming in the scientific literature by John Cook and a large number of contributors to the website Skeptical Science (Cook et al 2013), looked at 11,944 papers over a 21 year period and assigned each to one of three categories on the basis of the papers’ abstracts: endorse, reject, or take no position on the consensus. Of the papers that either endorsed or rejected the consensus, 97.1% of the papers and 98.4% of the papers’ authors endorsed the consensus. In addition, 1200 authors of the analyzed papers were contacted and asked to self-rate their own papers for level of endorsement. Of the self-rated papers that either endorsed or rejected the consensus, 97.2% of the papers and 96.4% of the authors endorsed the consensus.

'Overwhelming' consensus for manmade warming

A comprehensive assessment of climate change research has found an overwhelming consensus among scientists that recent warming is human-induced.

Scientists Agree (Again)

Public opinion on the topic of climate change is notoriously fickle, changing -- quite literally sometimes -- with the weather. The latest bit of evidence on this: Yale's April 2013 climate change survey, which found, among other things, that Americans' conviction that global warming is happening had dropped by seven points, to 63 percent, over the preceding six months. The decline, the authors surmised, was most likely due to "the cold winter of 2012-13 and an unusually cold March just before the survey was conducted."

Scientists agree global warming is man-made

An overwhelming majority of scientists agree humans have caused global warming, according to a study of scientific literature produced over the past two decades that claims to be the most comprehensive of its kind.

Scientific 'consensus' that humans to blame

A review of 12,000 scientific papers has found the consensus among scientists that humans are to blame for climate change is "overwhelming" and the dissenting view was held by less than two per cent of scientists.

Scientists say united on global warming

Ninety-seven percent of scientists say global warming is mainly man-made but a wide public belief that experts are divided is making it harder to gain support for policies to curb climate change, an international study showed on Thursday.

Survey finds 97% of climate science papers agree

Our team of citizen science volunteers at Skeptical Science has published a new survey in the journal Environmental Research Letters of over 12,000 peer-reviewed climate science papers, as the Guardian reports today. This is the most comprehensive survey of its kind, and the inspiration of this blog's name: Climate Consensus – the 97%.
