Climate change denial (also global warming denial) is a form of science denial characterized by rejecting, refusing to acknowledge, disputing, or fighting the scientific consensus on climate change.

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).
Publicity has surrounded claims of a global warming hiatus during the period 1998–2013.

A BBC weather forecast for the year 2050 shows that summer temperatures of 38 °C for the UK are "par for the course". The probable range by which the planet will warm over the next century is between 1.4 °C and 5.8 °C. Or, says Attenborough, "to put it another way, the impact of global warming will be somewhere between severe and catastrophic."
The deception is the hypothesis that human production of CO2 is causing global warming. The hypothesis is referred to as Anthropogenic Global Warming (AGW). The agency that carried out the deception was the UN Intergovernmental Panel on Climate Change (IPCC). [20]
