The weather is getting worse, says one expert.
Torrential rains fall in the Houston area more often than they used to, according to an unpublished analysis from state climatologist John Nielsen-Gammon.
Heavy precipitation of any particular magnitude are twice as likely to fall in the Bayou City today as they were in the early 20th Century. Downpours that struck every two years back then come every year on average now. Deluges that used to drop each 100, 500 or 1000 years should fall more frequently as well.
Nielsen-Gammon, a climate scientist at Texas A&M University who was appointed state climatologist by Gov. George W. Bush in 2000, reviewed data from rainfall gauges across the state, some with records dating to the late 19th Century. For Harris County, he drew from 17 gauges.
“We’ve confirmed that there’s an overall increase in extreme rainfall in Texas over the past century,” he said. “Specifically for Houston the increase has been particularly large.”
An independent analysis of local rainfall data from the National Weather Service also confirmed the state climatologist’s findings. Of the 100 rainiest days in Houston since 1890, as measured at multiple gauge sites, the wettest of the wet are skewed dramatically towards the last four decades.
You can see the charts and graphs and stuff at the story link. If you’re saying to yourself “weren’t we worried just a few years ago that we’d dry out and turns to dust from lack of rain?”, the answer is yes, and the reason is because we’re getting fewer rain events with more rain in them. Fewer rainstorms, in other words, but more of the storms we do get are big, and they’re more likely to come in groups rather than be spread out more or less evenly over time. Isn’t that awesome? But don’t worry, climate change is still a myth propagated by liberals, so we don’t have anything to worry about and we surely don’t have to change any of our habits in any way.
