"Chapters 24 and 25" For your primary post, provide a link to a current news article or science article that is related to at least one topic from Chapter 24 “Oceans, Atmosphere & Climatic Effects” and/or Chapter 25 “Driving Forces of Weather.”

In addition to the link, write a paragraph of at least 125 words describing the article and how it relates to the material from the textbook. Which concepts from the text does it mention, cover or depend on? Is the article more or less detailed on the science than the textbook?

Make a substantive reply to the fellow student below.

Hello Professor and Classmates

The article that I chose focuses on the introduction of 5G mobile phone networks, and how they can affect weather forecasters and their ability to predict major storms. It focuses on the radio frequencies that the new 5g networks use, and how they can affect Earth observations made by weather satellites. These satellites are important because they look down on the atmosphere and study factors like rain, snow, cloud cover, ice content, as well as other factors that influence our weather. The problem with the 5g network is that they transmit a frequency like the one that water vapor gives out, and it would make a signal that looks like its presence in the atmosphere. Scientists say that this is very dangerous, because they wouldn't be able to tell the difference and it would compromise their ability to make forecasts that are accurate. It makes it worse because the US Federal Communications Commission as well as other agencies in the world have already started auctioning off frequencies to future 5g providers. For example, the 23.8 gigahertz frequency is how water vapor emits a frequency, and forecasters use it to work out how a storm or weather system develops. Another frequency includes the 36-37 gigahertz band, which forecasters use to study rain and snow. This article does focus on weather -- specifically about storm fronts, rain, snow, etc. It isn't as detailed as the topics in the book are, where they focus on specific storm fronts, atmosphere, etc.

I got this article from The Guardian website
