Apr 07, · A: Global warming occurs when carbon dioxide (CO 2) and other air pollutants collect in the atmosphere and absorb sunlight and solar radiation that Jun 24, · Paragraph on Global Warming – Words for Classes 1, 2, 3 Kids. Global warming is the increase in the average temperature of the earth’s atmosphere. It is caused by the rise in carbon dioxide levels in the atmosphere, which leads to an increase in temperature. Global warming has been accelerated due to mass deforestation activities by man Climate Change Due To Global Warming. A universal consensus of climate scientists is that there has definitely been a rise in the global temperature over the past century. The phenomenon of Global Warming if continued unchecked will have profound implications. One of the main effects of global warming will be the rise in sea and ocean levels
Global warming controversy - Wikipedia
The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action can or should be taken to curb it, and if so what that action should be. In the scientific literaturethere is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases.
The controversy is, by now, political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. Political and popular debate concerning the existence and cause of global warming includes the reasons for the increase seen in the instrumental temperature recordwhether the warming trend exceeds normal climatic variations, and whether human activities have contributed significantly to it.
Scientists have resolved these questions decisively in favor of the view that the current warming trend exists and is ongoing, that human activity is the cause, and that it is without papers on global warming in at least years. Global warming remains an issue of widespread political debate, often split along party political lines, especially in the United States.
The sources of funding for those involved with climate science opposing mainstream scientific positions have been questioned. There are debates about the best policy responses to the sciencetheir cost-effectiveness and their urgency.
Climate scientists, especially in the United States, have reported government and oil-industry pressure to censor or suppress their work and hide scientific data, with directives not to discuss the subject in public communications. Legal cases regarding global warming, its effects, and measures to reduce it have reached American courts, papers on global warming. The fossil fuels lobby has been identified as overtly or covertly supporting efforts to undermine or discredit the scientific consensus on global warming.
In the United Statesthe mass media devoted little coverage to global warming until the drought ofand James E. Hansen 's testimony to the Senatewhich explicitly attributed "the abnormally hot weather plaguing our nation" to global warming. Global warming in the U. The British press also changed its coverage at the end offollowing a speech by Margaret Thatcher to the Royal Society advocating action against human-induced climate change.
At the same time environmental organizations and the political opposition were demanding "solutions that contrasted with the government's". If a doctor sees a child with a fever, he can't wait for [endless] tests. He has to act on what is there. Many European countries took action to reduce papers on global warming gas emissions before West Germany started to take action after the Green Party took seats in Parliament in the s.
All countries of the European Union ratified the Kyoto Protocol. Substantial activity by NGOs took place as well.
The theory that increases in greenhouse gases would lead to an increase in temperature was first proposed by the Swedish chemist Svante Arrhenius inbut climate change did not arise as a political issue until the s. It took many years for this particular issue to attract any type of attention. In Europe, the notion of human influence on climate gained wide acceptance more rapidly than in the United States and other countries.
Papers on global warmingthe BBC announced the cancellation of a planned television special Planet Reliefwhich would have highlighted the global warming issue and included a mass electrical switch-off. I think there are a lot of people who think that, but it must be stopped. The authors of the book Merchants of Doubtprovide documentation for the assertion that professional deniers have tried to sow seeds of doubt in public opinion in order to halt any meaningful social or political progress to reduce the impact of human carbon emissions.
The fact that only half of the American population believes global warming is caused by human activity could be seen as a victory for these deniers. A compendium of poll results on public perceptions about global warming is below.
Ina report on public perceptions in the United Kingdom by Ipsos MORI [36] reported that. The Canadian science broadcaster and environmental activist David Suzuki reports that focus groups organized by the David Suzuki Foundation in showed that the public has a poor understanding of the science behind global warming.
An example of the poor understanding is public confusion between global warming and ozone depletion or other environmental problems. But there is no evidence of alarm over global warming in either the United States or China —the two largest producers of greenhouse gases. A nation poll papers on global warming Pew Global Attitudes conducted infound, "Substantial majorities 25 of 37 countries say global warming is a 'very serious' problem.
There are differences between the opinion of scientists and that of the general public, papers on global warming. Many of the critics of the consensus view on global warming have disagreed, in whole or part, with the scientific consensus regarding other issues, particularly those relating to environmental risks, such as ozone depletionDDTand passive smoking. Mooney says that the promotion of doubt regarding issues that are politically, but not scientifically, controversial became increasingly prevalent under the George W.
This is also the subject of a book by environmental lawyer Robert F. Kennedy, papers on global warming, Jr. titled Crimes Against Nature: How George W. Bush and Corporate Pals are Plundering the Country and Hijacking Our Democracy ISBN Another book on this topic is The Assault on Reason by former Vice President of the United States Al Gore.
The Heat Is On by Ross Gelbspan chronicles how Congress tied climate change denial to attacks on the scientific bases for ozone depletion and asbestos removal, among other topics. Some critics of the scientific consensus on global warming have argued that these issues should not be linked and that reference to them constitutes an unjustified ad hominem attack. Inaccording to The New York Times and others, oil companies knew that papers on global warming oil and gas could cause global warming since the s but, nonetheless, funded deniers for years.
The findings that the climate has warmed in recent decades and that human activities are producing global climate change have been endorsed by every national science academy that has issued a statement on climate change, including the science academies of all of the major industrialized countries. Attribution of recent climate change discusses how global warming is attributed to anthropogenic greenhouse gases GHGs.
Scientific consensus is normally achieved through communication at conferences, publication in the scientific literaturepapers on global warming, replication reproducible results by othersand peer review. In the case of global warming, many governmental reports, papers on global warming, the media in many countries, and environmental groupshave stated that there is virtually unanimous scientific agreement that human-caused global warming is real and poses a serious concern.
While much remains to be learned, the core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations. Such conclusions and theories are then regarded as settled facts. This is the case for the conclusions that the Earth system is warming and that much of this warming is very likely due to human activities.
Among opponents of the mainstream scientific assessment, some say that while there is agreement papers on global warming humans do have an effect on climate, there is no universal agreement about the quantitative magnitude of anthropogenic global warming AGW relative to natural forcings and its harm-to-benefit ratio. Dennis T. Averya food policy analyst at the Hudson Institutewrote an article titled " Scientists Whose Research Contradicts Man-Made Global Warming Papers on global warming [68] published inby The Heartland Institute.
The list was immediately called into question for misunderstanding and distorting the conclusions of many of the named studies and citing outdated, flawed studies that had long been abandoned.
Many of the scientists included in the list demanded their names be removed. Those who don't agree, are, unfortunately—and this is hard to say without sounding elitist—mostly either not actually climate researchers or not very productive researchers. A study, published in the peer-reviewed journal Environmental Research Letters analyzed 11, abstracts from papers published in the peer-reviewed scientific literature between andpapers on global warming, identified by searching the ISI Web of Science citation index engine for the text strings "global climate change" or "global warming".
The authors found that of the 11, abstracts, endorsed that consensus, took no position on papers on global warming, 78 rejected the consensus, and 40 expressed uncertainty about it. Ina letter from 52 leading skeptics was published by the Committee for Skeptical Inquiry supporting the scientific consensus and asking the media to stop referring to deniers as "skeptics. The most appropriate word to describe the behavior of those individuals is 'denial'.
Not all individuals who call themselves climate change papers on global warming are deniers. But virtually all deniers have falsely branded themselves as skeptics. By perpetrating this misnomer, journalists have granted undeserved credibility to those who reject science and scientific inquiry, papers on global warming.
The "standard" view of climate change has papers on global warming to be defined by the reports of the IPCC, papers on global warming is supported by many other science academies and scientific organizations, papers on global warming. Insixteen of the world's national science academies made a joint statement on climate change, and gave their support for the IPCC.
Opponents have generally attacked either the IPCC's processes, people [77] or the Synthesis and Executive summaries; the full reports attract less attention. Some of the controversy and criticism has originated from experts invited by the IPCC to submit reports or serve on its panels.
Christopher Landseaa hurricane researcher, said of "the part of the IPCC to which my expertise is relevant" that "I personally cannot in good faith continue to contribute to a process that I view as both being motivated papers on global warming pre-conceived agendas and being scientifically unsound," [78] because of comments made at a press conference by Kevin Trenberth of which Landsea disapproved.
Trenberth said "Landsea's comments were not correct"; [79] the IPCC replied "individual scientists can do what they wish in their own rights, as long as they are not saying anything on behalf of the IPCC" and offered to include Landsea in the review phase of the AR4.
commented "Both Landsea and Trenberth can and should feel vindicated the IPCC accurately reported the state of scientific understandings of tropical cyclones and climate change in its recent summary for policy makers. Inthe House of Lords Economics Committee wrote, "We have some concerns about the objectivity of the IPCC process, with some of its emissions scenarios and summary documentation apparently influenced by political considerations. Speaking to the difficulty papers on global warming establishing scientific consensus on the precise extent of human action on climate change, John Christya contributing author, wrote:, papers on global warming.
Contributing authors essentially are asked to contribute a little text at the beginning and to review the first two drafts. We have no control over editing decisions. Even less influence is granted the 2, or so reviewers.
Thus, to say that contributing authors or 2, reviewers reached consensus on anything describes a situation that is not reality. On 10 Decembera report was released by the U. Senate Committee on Environment and Public Works Minority members, under the leadership of the Senate's most vocal global warming skeptic Jim Inhofe.
The timing of the report coincided with the UN global warming conference in Poznań, Poland. It says it summarizes scientific dissent from the IPCC. While some critics have argued that the IPCC overstates likely global warming, others have made the opposite criticism. David Biello, writing in the Scientific American papers on global warming, argues that, because of the need to secure consensus among governmental representatives, the IPCC reports give conservative estimates of the likely extent and effects of global warming.
Hansen argues that the IPCC's conservativeness seriously underestimates the risk of sea-level rise on the order of meters—enough to inundate many low-lying areas, such as the southern third of Florida.
Pielke Sr. has also stated "Humans are significantly altering the global climate, but in a variety of diverse ways beyond the radiative effect of carbon dioxide. The IPCC assessments have been too conservative in recognizing the importance of these human climate forcings as they alter regional and global climate.
Henderson-Sellers has collected comments from IPCC authors in a workshop revealing a number of concerns. She concluded, "Climate change research entered a new and different regime with the publication of the IPCC Fourth Assessment Report.
Attribution of recent climate change discusses the evidence for recent global warming. Nonetheless, one argument against global warming says that rising levels of carbon dioxide CO 2 and other greenhouse gases GHGs do not correlate with global warming.
As noted above, papers on global warming, climate models are only able to simulate the temperature record of the past century when GHG forcing is included, being consistent with the findings of the IPCC which has stated that: "Greenhouse gas forcing, largely the result of human activities, has very likely caused most of the observed global warming over the last 50 years" [].
The "standard" set of scenarios for future atmospheric greenhouse gases are the IPCC SRES scenarios. The purpose of the range of scenarios is not to predict what exact course the future of emissions will take, but what it may take under a range of possible population, economic and societal trends.
There is debate about the various scenarios for fossil fuel consumption. Global warming skeptic Fred Singer stated "some good experts believe" that atmospheric CO 2 concentration will not double since economies are becoming less reliant on carbon.

Consider what this means for the global-warming hypothesis. This hypothesis predicts that global temperatures will rise significantly, indeed catastrophically, if atmospheric carbon dioxide rises. Most of the increase in atmospheric carbon dioxide has occurred during the past 50 years, and the increase has continued during the past 20 years A global warming conspiracy theory invokes claims that the scientific consensus on global warming is based on conspiracies to produce manipulated data or suppress dissent. It is one of a number of tactics used in climate change denial to attempt to manufacture political and public controversy disputing this consensus. Conspiracy theorists typically allege that, through worldwide acts of Global Warming Definition: "Global warming is a consistent upsurge in the earth's average temperature denoted by increasing global surface temperatures caused or influenced by the uninterrupted emissions of greenhouse gases, over 90% of the air getting polluted by carbon dioxide and CFCs like Methane and Nitrous oxide and other air pollutants affecting the climate sensitivity and levels of
