For some reason, hurricanes are terrified of South America. In fact, as long as we’ve been keeping track, it’s only EVER been hit by ONE! Hurricane Catarina was the hurricane that, according to meteorology, never should have happened. So how did it? On this episode of Weathered, we take a tour of hurricane regions around the world to answer that question. And we find out what Catarina can teach us about how hurricanes really work, and how they’re changing.Catarina features in An Inconvenient Truth as a possible example of climate change affecting hurricanes, typhoons, cyclones, and tropical storms: "Explain how the 2004-2005 hurricane seasons fit with predictions based on global warming." That no hurricane has formed in the South Atlantic since shows that it was most likely a fluke and may have nothing to do with climate change. That doesn't detract from what Maiya May and other meteorologist learned from it nor from the other predictions, that hurricanes will get stronger and rising sea levels will increase the amount of storm surge, making coastal flooding worse. That's the answer to a question I ask in Chasing Ice, which replaced An Inconvenient Truth: "What effect will rising sea level have on hurricanes and typhoons?" California is seeing that right now as a result of El Niño amplifying the waves of Tropical Storm Rachel, something I'll mention to my students next week.
Speaking of my students, I also teach them the metric system, which reminds me that today is NATIONAL METRIC DAY | October 10th - National Day Calendar.
October 10th is National Metric Day!I'm recycling what I wrote in Discovery News and I rant in favor of the metric system for my reaction.
Marlo Anderson tells us some history and benefits of the metric system.
In my Environmental Science class, the lab I run is one to introduce my students to the metric system, which many of my students struggle with. In fact, their issues with it are such that I tell my students a joke about it. "There are only three groups of students in community college who understand the metric system, the science nerds, the foreign students, and the drug dealers." That never fails to get a laugh.My joke has changed a little over the past 13 years, as some gamers also understand the metric system thanks to their games using it, but my opinion hasn't.
My job would be a lot easier and I could cover something else if the United States fully adopted the metric system.
That's a wrap for today. Stay tuned for the winners of Outstanding Reality Competition Program and related categories as the Sunday entertainment feature on National Coming Out Day followed by Indigenous Peoples' Day.
