Detailed explanation-1: -Yes, the vast majority of actively publishing climate scientists – 97 percent – agree that humans are causing global warming and climate change.
Detailed explanation-2: -Global warming: It is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.
Detailed explanation-3: -Of these, 97% agree, explicitly or implicitly, that global warming is happening and is human-caused.
Detailed explanation-4: -Global warming is the long-term warming of the planet’s overall temperature. Though this warming trend has been going on for a long time, its pace has significantly increased in the last hundred years due to the burning of fossil fuels. As the human population has increased, so has the volume of fossil fuels burned.
