Is Rain Getting Heavier In The US?
The number of large floods in the US has increased in the last year compared to most of the previous several decades. Maybe not.
The open question is whether rain has been caused by climate change or normal weather cycles. The Intertropical Convergence Zone may have moved north. NOAA describes it as “a band of clouds consisting of showers and occasional thunderstorms that encircles the globe near the equator. The solid band of clouds may extend for many hundreds of miles and is sometimes broken into smaller line segments.” Tradewinds move it.
Axios points out that this may not be permanent but merely an “exaggeration.” It reports, “There are clear climate change ties to the extreme rains, but formal studies will have to be done to tease out the climate signals from the background noise of natural climate variability.”
The idea that these changes are part of a long-term cycle and not climate change also feeds climate denier’s arguments.
