The argument that scientists were wrong about global cooling, so therefore may be wrong about global warming has been called "the "Ice Age Fallacy" by Time author Bryan Walsh. [ 79 ] In the first two "Reports for the Club of Rome" in 1972 [ 80 ] and 1974, [ 81 ] the anthropogenic climate changes by CO 2 increase as well as by waste heat were ...
Avoiding this future warming will require a large and rapid reduction in global greenhouse gas emissions. The ongoing warming will increase risks and stresses to human societies, economies, ecosystems, and wildlife through the 21st century and beyond, making it imperative that society respond to a changing climate.
The controversies are, by now, mostly political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity. [2] Public debates that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases (climate sensitivity).
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes.

Matthew C. Nisbet and Teresa Myers' 2007 article—"Twenty Years of Public Opinion about Global Warming"—covered two decades in the United States starting in 1980—in which they investigated public awareness of the causes and impacts of global warming, public policy, scientific consensus on climate change, public support for the Kyoto Accord ...
On a scale of 1 out of 7, where higher numbers indicated greater disagreement, "global warming is already underway" had a mean rating of 3.4, and "global warming will occur in the future" had an even greater agreement of 2.6 Surveyed scientists had less confidence in the accuracy of contemporary climate models, rating their ability to make ...
“There is a general strong consensus among Pennsylvanians for climate action,” a State College resident writes.
Climate change has become a concern for a number of disciplines due to its potentially catastrophic impacts on environmental systems, wildlife, nature, and humans.Climate change poses a serious threat to the global economy as economic development, especially in the West, has been largely dependent on the extraction and burning of fossil fuels since the Industrial Revolution.
