Climate is always changing. The theory that man made greenhouse gas emissions is causing catastrophic global warming hasn't been experimentally tested. Therefor, climate change mitigation is a hoax.
Wow--watching FOX news perhaps for your source?
#1 virtually all the world renown science agencies have put out statements warning about the potential serious threats of global warming:
"Since 2007, no scientific body of national or international standing has maintained a dissenting opinion [on global warming - see below]. A few organizations hold non-committal positions >>

The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society. Accumulating data from across the globe reveal a wide array of effects: rapidly melting glaciers, destabilization of major ice sheets, increases in extreme weather, rising sea level, shifts in species ranges, and more. The pace of change and the evidence of harm have increased markedly over the last five years. The time to control greenhouse gas emissions is now. The atmospheric concentration of carbon dioxide, a critical greenhouse gas, is higher than it has been for at least 650,000 years.
The average temperature of the Earth is heading for levels not experienced for millions of years. Scientific predictions of the impacts of increasing atmospheric concentrations of greenhouse gases from fossil fuels and deforestation match observed changes. As expected, intensification of droughts, heat waves, floods, wildfires, and severe storms is occur Delaying action to address climate change will increase the environmental and societal consequences as well as the costs. The longer we wait to tackle climate change, the harder and more expensive the task will be.
