GEOLOGY

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: -The greenhouse gases contribute to the greenhouse effect by absorbing infrared radiation from the piles of the earth’s surface. Climate scientists believe that the enhancement of the greenhouse effect is the major cause of climate change on earth.

Detailed explanation-3: -The current scientific consensus is that: Earth’s climate has warmed significantly since the late 1800s. Human activities (primarily greenhouse gas emissions) are the primary cause. Continuing emissions will increase the likelihood and severity of global effects.

Detailed explanation-4: -Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions.

Detailed explanation-5: -Climate change is caused by humans. Scientists have concluded that most of the observed warming is very likely due to the burning of coal, oil, and gas.
