Detailed explanation-1: -Global warming causes climate change, which poses a serious threat to life on Earth in the forms of widespread flooding and extreme weather. Scientists continue to study global warming and its impact on Earth. greenhouse gas produced by animals during respiration and used by plants during photosynthesis.

Detailed explanation-2: -Global warming is the long-term heating of Earth’s surface 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: -A: Scientists agree that the earth’s rising temperatures are fueling longer and hotter heat waves, more frequent droughts, heavier rainfall, and more powerful hurricanes.

Detailed explanation-4: -Yes, the vast majority of actively publishing climate scientists – 97 percent – agree that humans are causing global warming and climate change.

Detailed explanation-5: -Most places on Earth are warmer than they were 100 years ago. Although most locations on the planet have recorded increased temperatures since 1880, changes in global ocean and atmospheric circulation patterns have created small-scale temperature decreases in a few local regions.
