Climate research nearly unanimous
Of more than 4,000 academic papers published over 20 years, 97.1% agreed that climate change is anthropogenic.
Climate research nearly unanimous on human causes, survey findsby Suzanne Goldenberg, May 15, 2013
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.

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 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%.

|Measure the climate consensus yourself with our Interactive Rating System - Fri, 17 May 2013 01:53:14 EST|
The Consensus Projectwas a long, ambitious effort by many volunteers, lasting 12 months from beginning to submission ofour paperto peer-reviewed journalEnvironmental Research Letters. The project involved citizen science from start to finish - from the rating of the abstracts to the collection of scientists' emails tocrowd-funding the journal fee to make the paper free to the public. It was an enormous collaborative effort that the entire Skeptical Science community contributed to. The effort has resulted instrong media interestincluding atweet from President Obama.
We want our results to be transparent and replicable, so that anybody can quantify the scientific consensus on human-caused global warming for themselves. Thus we've created aninteractive rating systemthat lets Skeptical Science readers rate the abstracts from The Consensus Project. You can thencompare your ratingsto the results fromQuantifying The Consensus. Note that your ratings are private - no specific ratings will be publicly attributed to individuals.
All papers receive two types of ratings - the category of research and the level of endorsement of anthropogenic global warming (AGW). Here are general definitions of each category and endorsement level, although we've also provided amore detailed set of guidelines.
Level of Endorsement
The purpose of the interactive rating systemis to replicate our experience of reading and categorising peer-reviewed climate research, to gain a deeper insight into ourQuantifying The Consensuspaper by participating in the process yourself. Check out the diversity of climate research on offer and try for yourself the categorisation of the papers' abstracts. All papers from our analysis are available for rating except the ones that had no abstract (47 papers). Please share your thoughts in this comments thread on the rating system, the categorisation guidelines, the climate research and other thoughts related to ourQuantifying The Consensuspaper.
Depending on how popular this feature is, I hope to continue adding features to theinteractive rating system. Some possible features include visualisations of your ratings and a leaderboard of most productive raters.

A change in temperature
Since 1896, scientists have been trying to answer a deceptively simple question: What will happen to the temperature of the earth if the amount of carbon dioxide in the atmosphere doubles?

Canada sells out science
Over the past few years, the Canadian government has been lurching into antiscience territory. For example, they’ve been muzzling scientists, essentially censoring them from talking about their research. Scientists have fought back against this, though from what I hear with limited success.
But a new development makes the situation appear to be far worse. In a stunning announcement, the National Research Council—the Canadian scientific research and development agency—has now said that they will only perform research that has“social or economic gain”.
This is not a joke. I wish it were.

Climate change 'will make hundreds of millions homeless'
It is increasingly likely that hundreds of millions of people will be displaced from their homelands in the near future as a result of global warming. That is the stark warning of economist and climate change expert Lord Stern following the news last week that concentrations of carbon dioxide in our atmosphere had reached a level of 400 parts per million (ppm).

Fewer Rain Forests Mean Less Energy
The loss of tropical rain forests is likely to reduce the energy output of hydroelectric projects in countries like Brazil that are investing billions of dollars to create power to support economic growth.
That is the conclusion of a group of experts whose findings, released Monday, run counter to the conventional understanding of deforestation’s impact on watersheds.

Warmer climate threatens Africa’s vital cassava crop
A plant which is a staple food crop for millions of people across Africa is at risk from disease as regional temperatures rise, scientists say.
The plant, cassava, is a significant source of food and income, and is an important industrial crop, and there is concern that serious food shortages may result and poverty worsen.
Experts say the spread of the disease could halve cassava production and threaten the diets of 300 million people.
