"It’s been an open secret, ever since Dr. Michael Mann used “Mike’s Nature Trick” to “hide the decline” by covering up some inconvenient tree ring data in the hockey stick climate graph, that climate alarmists will go to almost any length to only show the public the “crisis side” of climate data.
The National Interagency Fire Center (NIFC) has been the keeper of U.S. wildfire data for decades, tracking both the number of wildfires and acreage burned all the way back to 1926. However, after making that entire dataset public for decades, now, in a blatant act of cherry picking, NIFC “disappeared” a portion of it, and only show data from 1983. You can see it here.
Fortunately, the Internet never forgets, and the entire dataset is preserved on the Internet Wayback machine and other places, despite NIFC’s ham-handed attempt to disappear the data.
Why would they do this you ask?
The answer is simple; data prior to 1983 shows that U.S. wildfires were far worse both in frequency and total acreage burned. By disappearing all data prior to 1983, which just happens to be the lowest point in the dataset, now all of the sudden we get a positive slope of worsening wildfire aligning with increased global temperature, which is perfect for claiming “climate change is making wildfire worse”. See figure 1 below for a before and after comparison of what the data looks like when you plot it...Read all.
