The governments, scientists, engineers, inventors & some corporations are not in denial about climate change because they have developed a large variety of programs & technology to combat climate change such as renewable energy systems.
Basically renewable energy systems involve . . .
Biofuel
Biomass
Geothermal
Hydroelectricity
Solar energy
Tidal power
Wave power
Wind power
However turning these renewable energy systems into renewable energy infrastructure requires public support, especially the public being willing to work in constructing & maintaining renewable energy infrastructure.
