I know this because every prediction of climate doom turned out to be false.
Entire nations were going to disappear under rising sea levels. It has not happened. I'm not saying no land sinks, but sea levels are not rising rapidly enough to prevent Al Gore (author of "An Inconvenient Truth") from buying an ocean-front home. The same applies to John Kerry and dozens of other outspoken prophets of doom who warned us that rising sea levels would submerge entire nations. They used the proceeds of their fear-mongering to buy oceanfront homes.
I remember signs in Glacier National Park telling us the glaciers would be gone by the year 2,000. It has not happened.
This "signal" too will pass.
