How do you "show" instead of "telling" in a Global warming research essay?

I am suppose to write an essay where I need to "show" instead of "telling" in the essay, I am confused about this topic.

Must include the following in the essay.

What happens if the global warming is real and we take action?
what happen if the global warming is not real and we take actions?
what happens if global warming is real and we take no action?

I am suppose to write an 700 words essay on the above questions but I don't know how to "show" instead of telling.

The best way to show rather than telling is having more examples to support your claims. Let's take each question;


Tell what you think will happen and give some evidence to convince the reader. You can google on this topic and find many ideas. try this link'; aip.org/history/climate/impacts.htm

Same way you can tackle other two questions too :)
