According to a 2014 Pew Research Center poll, 40% of the US public believes global warming is caused by human activity, 35% believe that there is no solid evidence that global warming is occurring at all, and 18% believe global warming is occurring due to natural causes.
Scientists have known of the heating potential (greenhouse effect) of gases such as CO2 since at least 1859, when British physicist John Tyndall first began experiments leading to the discovery that CO2 in the atmosphere absorbs the sun's heat.
The Intergovernmental Panel on Climate Change (IPCC) was created in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) to review research on global climate change. The IPCC issued its first assessment report in 1990 stating that "emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases," resulting in "an additional warming of the Earth's surface."
According to NOAA's National Climatic Data Center, 2014 was the hottest year on record across the globe since 1880 when record keeping began. The 10 warmest years in this 135-year period occurred between 1998 and 2014.
According to the US Global Change Research Program, as of 2010 the US had 4.5% of the world's population but was responsible for about 28% of all global greenhouse gas emissions.
However, its not too late to put a stop to climate change. Here we have 9 things that will put an end to global warming:
