The cartoon's purpose is to show how large political leaders will ignore a problem, such as climate change, because the "cost" in terms of money is too large. The leader claims he "used to agree" with the fact that climate change is a real problem, however after discovering the amount of money needed to fix that problem he decided to support the fact that it is a "hoax." I agree with the cartoon in the sense that large and powerful political leaders are unwilling to pay the cost for problems, solely because they don't want to pay the amount. I also agree that instead of saying the facts, some leaders will say things that will only benefit them, factual or not.

"a testimonial" would most likely include positive information about one side of an issue, although it should be noted that this is not always the case with testimonials.
