Climate change conspiracy theories and denial have resulted in poor action or no action at all to effectively mitigate the damage done by global warming. 40% of Americans believed (ca. 2017) that climate change is a hoax [276] even though 100% of climate scientists (as of 2019) believe it is real.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
There have been debates on the best responses to slow global warming, and their timing. The debates are around the specific actions for climate change mitigation and climate change adaptation, or climate action in general. See for example: Economic analysis of climate change; Climate change denial#Delaying climate change mitigation measures
After Trump pulled the U.S. from the Paris Agreement on climate change during his first term, the Biden-Harris administration reentered the global pact aimed at reducing emissions. The administration also set a target to slash U.S. emissions 50% by 2030 and put forth policy to accelerate clean energy projects and shift away from fossil fuels.
The declaration also criticised the United Nations Framework Convention on Climate Change, saying: "Energy is essential for all economic growth, and fossil fuels provide today's principal global energy source. In a world in which poverty is the greatest social pollutant, any restriction on energy use that inhibits economic growth should be ...
In 2004, the geologist and historian of science Naomi Oreskes analyzed the abstracts of 928 scientific papers on "global climate change" published between 1993 and 2003. 75% had either explicitly expressed support for the scientific consensus on anthropogenic climate change, or had accepted it as a given and were focused on evaluating its ...
The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the ...
Amardeo Sarma lecturing about climate change denialism at the European Skeptics Congress, hosted by the Association for Skeptical Enquiry. A global warming hiatus, [1] also sometimes referred to as a global warming pause [2] or a global warming slowdown, [3] is a period of relatively little change in globally averaged surface temperatures.
