Global warming controversy
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 should be taken to curb it, and if so what that action should be. In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused primarily by human-induced emissions of greenhouse gases. No scientific body of national or international standing disagrees with this view, though a few organizations with members in extractive industries hold non-committal positions. Disputes over the key scientific facts of global warming are now more prevalent in the popular media than in the scientific literature, where such issues are treated as resolved, and more in the United States than globally.Political and popular debate concerning the existence and cause of climate change includes the reasons for the increase seen in the instrumental temperature record, whether the warming trend exceeds normal climatic variations, and whether human activities have contributed significantly to it. Scientists have resolved many of these questions decisively in favour of the view that the current warming trend exists and is ongoing, that human activity is the primary cause, and that it is without precedent in at least 2000 years. Disputes that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases (climate sensitivity), and what the consequences of global warming will be.Global warming remains an issue of widespread political debate, often split along party political lines, especially in the United States. Many of the largely settled scientific issues, such as the human responsibility for global warming, remain the subject of politically or economically motivated attempts to downplay, dismiss or deny them – an ideological phenomenon categorised by academics and scientists as climate change denial. The sources of funding for those involved with climate science – both supporting and opposing mainstream scientific positions – have been questioned by both sides. There are debates about the best policy responses to the science, their cost-effectiveness and their urgency. Climate scientists, especially in the United States, have reported official 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. The fossil fuels lobby and free market think tanks have often been identified as overtly or covertly supporting efforts to undermine or discredit the scientific consensus on global warming.
