Remember the "hockey stick graph" used by the charlatan Al Gore (winner of the Nobel Peace Prize and inventor of the Internet)?
Using falsified data, it purported to show a sharp rise in global temperatures in the past few years, which alarmists attributed to human activity.
Here's another graph with a blip at the end. This one is real.
The large uptick in the 1940s is, of course, the cost of winning World War II. This was followed by a decline and then another rise, followed by the dip after Republicans gained control of Congress in the mid 1990s. At the end is the sharp increase in debt that is the result of Republicans losing their way and then being replaced by tax-and-spend liberals who are even worse.

Next fall's congressional elections may help determine which way the trend will go -- even without concocted computer simulations.
