let me know when you find some papers with some science like the ones I posted to start the thread. we can all find quotes from scientists... but we need to evaluate the science.
first produce some papers... showing man made co2 causes warming... maybe then you post some sort lol.
I gave you links to a lot of papers on this warming, and the NASA site statement saying it's very likely Man doing it via CO2. Did you want me to print those to hardcopy and courier them over? : )
you gave us links to observations of warming... you did not give any links to science showing man made co2 is causing it. please don't start misrepresenting things like stu and fc you have shown integrity.
Look, it's simple. We analyze the evolution of the scientific consensus on anthropogenic global warming (AGW) in the peer-reviewed scientific literature, examining 11 944 climate abstracts from 1991–2011 matching the topics 'global climate change' or 'global warming'. We find that 66.4% of abstracts expressed no position on AGW, 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming. In a second phase of this study, we invited authors to rate their own papers. Compared to abstract ratings, a smaller percentage of self-rated papers expressed no position on AGW (35.5%). Among self-rated papers expressing a position on AGW, 97.2% endorsed the consensus. For both abstract ratings and authors' self-ratings, the percentage of endorsements among papers expressing a position on AGW marginally increased over time. Our analysis indicates that the number of papers rejecting the consensus on AGW is a vanishingly small proportion of the published research.
Why Climate Deniers Have No Scientific Credibility: Only 1 of 9,136 Recent Peer-Reviewed Authors Rejects Global Warming This is a guest post by James Lawrence Powell. I have brought my previous study (see here and here) up-to-date by reviewing peer-reviewed articles in scientific journals over the period from Nov. 12, 2012 through December 31, 2013. I found 2,258 articles, written by a total of 9,136 authors. (Download the chart above here.) Only one article, by a single author in the Herald of the Russian Academy of Sciences, rejected man-made global warming. I discuss that article here. My previous study, of the peer-reviewed literature from 1991 through Nov. 12, 2012, found 13,950 articles on “global warming” or “global climate change.” Of those, I judged that only 24 explicitly rejected the theory of man-made global warming. The methodology and details for the original and the new study are described here. Anyone can repeat as much of the new study as they wish–all of it if they like. Download an Excel database of the 2,258 articles here. It includes the title, document number, and Web of Science accession number. Scan the titles to identify articles that might reject man-made global warming. Then use the DOI or WoS accession number to find and read the abstracts of those articles, and where necessary, the entire article. If you find any candidates that I missed, please email me here. The scientific literature since 1991 contains a mountain of evidence confirming man-made global warming as true and no convincing evidence that it is false. Global warming denial is a house of cards.
The scientific opinion on climate change is that the Earth's climate system is unequivocally warming, and it is extremely likely (at least 95% probability) that humans are causing most of it through activities that increase concentrations of greenhouse gases in the atmosphere, such as deforestation and burning fossil fuels. In addition, it is likely that some potential further greenhouse gas warming has been offset by increased aerosols.[1][2][3][4] Thisscientific consensus is expressed in synthesis reports, by scientific bodies of national or international standing, and by surveys of opinion among climate scientists. Individual scientists, universities, and laboratories contribute to the overall scientific opinion via their peer-reviewed publications, and the areas of collective agreement and relative certainty are summarised in these high level reports and surveys. National and international science academies and scientific societies have assessed current scientific opinion on global warming. These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change, the IPCC Fourth Assessment Report summarized: Warming of the climate system is unequivocal, as evidenced by increases in global average air and ocean temperatures, the widespread melting ofsnow and ice, and rising global average sea level.[5] Most of the global warming since the mid-20th century is very likely due to human activities.[6] Benefits and costs of climate change for [human] society will vary widely by location and scale.[7] Some of the effects in temperate and polar regionswill be positive and others elsewhere will be negative.[7] Overall, net effects are more likely to be strongly negative with larger or more rapid warming.[7] The range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time.[8] The resilience of many ecosystems is likely to be exceeded this century by an unprecedented combination of climate change, associated disturbances (e.g. flooding, drought, wildfire,insects, ocean acidification) and other global change drivers (e.g. land-use change, pollution, fragmentation of natural systems, over-exploitation of resources).[9] No scientific body of national or international standing maintains a formal opinion dissenting from any of these main points. The last national or international scientific body to drop dissent was the American Association of Petroleum Geologists,[10] which in 2007[11] updated its statement to its current non-committal position.[12] Some other organizations, primarily those focusing on geology, also hold non-committal positions.
You know why the consensus is nearly unanimous? (right wing morons won't get this but) It's because CO2 is an important GHG and we have raised it's level by 40% This CO2 does NOT cool the earth. Just the opposite. Jerm seem confused about this.
