Look at this dip during the last week !

Could it be an anomaly with satellite imaging, a random statistical blip, or is something huge just about to start ?
Yep. I didn't mean to imply something wasn't happening, but that something isn't what OP pointed at, and that something is evidence of climate change.
People need to learn that its a slow decline. It's disastrous, but it looks like worsening wildfires each year. More tornados in Iowa and Minnesota. Lower crop yields. Beaches getting smaller by inches, ocean front property values declining and insurance rates increasing. More intense variations in weather and more difficultly forecasting.
