The new National Climate Assessment is riddled with shortcomings, from cherry-picked science and economic exaggerations to unfounded alarmism and fear-mongering.

This article does not deny climate change exists or call it a "hoax". What it does do is explain how the issue gets exaggerated and portrayed in an unrealistic fashion, particularly by government reports. The report this article refers to for instance uses both climate change and cost scenarios that are beyond the most extreme possibilities presented by most scientists. In addition, it cherry picks scientific data by looking at specific weather events instead of overall trends and using shorter timelines designed to make things look worse.
However, the worst part of all of this comes in the form of the policy proposals that would supposedly solve the problem or reduce its effects. What is proposed, among other things, is a potentially disastrous tax on carbon of up to $5,500/ton. This would be equivalent to a gas tax of $50/gallon and that's just one of a very many things that would be affected in extreme ways by such a tax. There is no scientific evidence to suggest that such taxes would do anything to mitigate climate change though they would certainly be economically disastrous, particularly for the poor and middle class.
These types of unrealistic reports are nothing new. In 1989 a similar report warned that entire nations could be wiped off the face of the earth due to global warming by the year 2000. You can only cry wolf so many times before people stop listening. I for one am willing to listen to realistic solutions to a realistic problem. Too bad there's no such thing when it comes to climate change.
