Question

In simple words, describe three pieces of evidence supporting scientists' position that climate change is occuring in our world right now.

What are two pieces of evidence that humans have influenced the rate of climate change in our world?

Answer 1

A. Three pieces of evidence supporting scientists' position that climate change is occurring in our world right now are:

1. Rise in global temperatures: Global warming has led to the rise in the average surface temperature of our planet earth by about 0.8 degree celsius since 1880s that has been figured out in research conducted by NASA.

2. Reduction in Ice sheets: The risen temeratures has resulted in loss of billion tons of ice cover at antarctic and greenland since 1990s as found in research conducted by NASA.

3. Alteration in pattern of rainfall and weather: The rise in global temperatures has affected the normal patterns of rainfall and weather conditions with occurrence of extreme weather events such as intense rainfall, droughts and heatwaves.

B. Two pieces of evidence that humans have influenced the rate of climate change in our world are:

1. Dependence on fossil fuels: Human activities in industry, transportation and farming contribute majorly to the release of green house gases, contributing directly in global warming and climate change.

2. De-forestation: Trees contribute in carbon dioxide capture and release of oxygen in the environment. Growing human population has led to an increase in the removal of trees for need of space, fuel or other purposes. This is another major cause of global warming contributing to climate change by humans.
