Most people do because of how humid air "feels".  But H2O has a lower molecular weight than oxygen or nitrogen.

When I've visited desert locales, one thing that surprised me was how quickly the heat dissipates once the sun goes down.

You can go into a restaurant at 7pm in heat that is just WAY too hot for this life-long midwesterner and come out a couple hours later needing a winter coat.

Yeah, you need to change clothes the instant the sun goes down. 

Then there's the reverse phenomenon, where people will dress warm because it's still cold in the mornings, but then the sun comes up and they are completely screwed.

From the NYT:


1) The world is on track to surpass a significant level of warming. The world is likely to hit what scientists consider relatively safe levels of warming — 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial temperatures — by the early 2030s, the report warned. Countries could still take steps to prevent that, by slashing greenhouse gas emissions in half by 2030 and no longer adding carbon dioxide to the atmosphere by the 2050s. But the required measures are so extreme that they seem increasingly unlikely, many experts say.

2) On the current track, brace for more disasters. Continued warming will mean more catastrophic flooding, deadly heat waves, crop-destroying droughts and other extreme weather. Some of those effects are already visible. Last year, record-breaking heat waves hit much of the world, including the U.S. and Europe, and floods submerged a third of Pakistan.
3) The world has made some real progress. In the past, climate reports warned that warming could surpass four degrees Celsius (7.2 degrees Fahrenheit) by 2100. Today, the Earth is on a trajectory of around two to three degrees Celsius (3.6 to 5.4 degrees Fahrenheit), thanks to the uptake of cleaner energy and to projections that coal use will decline. That difference of a few degrees can, like a fever, prevent more catastrophic events. And as my colleague Somini Sengupta noted, pivoting away from fossil fuels is the fastest way to stop global warming.

Item 3 is simply because the worst model projection was discarded, we have not made any real "progress", one can see how CO2 levels continue to rise at record rates.  This is disingenuous.  Anything based on "projections" is no sign of "real progress" either.


And of course any relationship between CC and extreme weather events is rather tenuous.  The predicted rise in hurricane strength and number has not as yet happened.

It's been below freezing here for several days in the AM, heat has been on of course.  We get a lot of sun in the AM which heats the place up nicely (and keep curtins drawn in summer).  Our friends with south facing condos get hammered in summer all day but have various blinds of course.  They rarely need heat in winter except at night.

We're off for a short trip up into the mountains, going to Gibb's Gardens again to see what it's like in early spring.

Just got back from camping out at Big Bend National Park in West Texas.  It got down to 36 degrees in the basin, and sub-freezing up at the top of the Chisos mountains.  It snowed up there all day on Saturday, which is pretty rare in West Texas.  It even snowed on us down in the valley.

The RV stayed a comfortable 70 degrees throughout.
