Cooler Weather

Share
On the heels of a huge wildfire now, Vegas has had significant rain this past week. We even set a record for the most rainfall at the airport in a single 24 hour period this week, beating a record set in 1951. Of course, the Church of Climate Change will ignore that information because they insist that things are getting inexorably warmer. They are committed to pseudoscience and investigate what supports the conclusions they already reached while ignoring everything else.

The rest of the country already knows why it’s cooler there than in Vegas. It was cooler in Vegas (in terms of degrees) this week because of the rain. It even dipped down to 89F one day as our July high, but they will still talk about the early 115F day even though it wasn’t a record. This has happened before. It’s just normally not that early, and the rest of July has been so much more temperate that I will spend only 75% of the money on Electric Air Conditioning this year compared to last. Why? This happened because in the rest of the company humidity keeps the temperature low. Nevada has very little water, hence low humiditiy, hence high temperatures, because water has a significantly higher specific heat compared to other molecules and then absorbs and retains things. This is one reason why we have a 20-30 degree temperature shift from day to night, because there is no water to release low amounts of heat all night long. The rocks release rapidly whatever thermoenergy they acquire, and we cool off until the sun peaks over the mountains in the morning.

Water vapor is the major regulator of atmospheric temperature. Venus, which has no water, is a whopping 5000F on the dark side of the planet, and Mars, which has no atmosphere, is cold because there is nothing to trap the energy. Between them, the earth sits, regulating its temperatures with the water on its surface. Water vapor is far more significant as a percentage of atmospheric gas than CO2, which has a statistically insignificant specific heat when accounting for significant figures compared to water.

Vegas had a mild summer in July because we had some good thunderstorms. The clouds radiated the heat back away from the state, and the rains picked up some of the heat from the area, even though they then evaporated into a sticky humid mess. It’s not as hot, just like in New Orleans, but it’s far less pleasant in my opinion. Even the children go outside to cool off in the water- sprinklers, pools, puddles, etc. It’s water that cools us like it cools our houses, our cars, and our bodies. Everything else is pseudoscience (images below courtesy of Weather.com).
