Negative Efforts to Reduce Global Warming

Those satellite temperature measurements all hover over cities to maximize the heat island effect.

"Those satellite temperature measurements all hover over cities to maximize the heat island effect."

I didn't see that line in the Wikipedia article, nor anything that would imply it. Would you please point out where that came from?

I think that was sarcasm.

I think you're right (and should have noticed earlier). Well-deserved sarcasm, too.

Do I detect a small bit of sarcasm? Satellites don't hover, some are in stationary orbits, but not these. These satellites are in polar orbits, sometimes they travel north to south others south to north. They switch directions when they reach Lat and Lon 000.0

If they are at the point of cooling the outdoors, maybe it is time to revisit the concept of towing icebergs into the harbor of coastal cities.

As the iceberg melts, it would absorb heat from the surrounding air and provide cooling with a net zero effect on the earth's atmosphere, since it would have melted anyway out in the open ocean. They would also reduce energy use by not having to distill seawater for freshwater.

"During the summer in some parts of the L.A. region, temperatures could jump 19 degrees Fahrenheit due to this effect."

"Air conditioning the outside" is both misleading and inaccurate. An air conditioner is a heat pump which pumps heat from inside your house to the outside. A heat pump exhausts more heat to the hot side (outside) than is removed from the cold side (inside the house), and thus is less than 100 percent efficient.

Increasing the reflectance (albedo) of the earth's surface is actually a positive way to reduce temperatures. When sunlight hits the surface, part of it is reflected and the rest is absorbed. What is absorbed is converted to heat, increasing temperature. Not only does reflecting sunlight back into space reduce temperatures, but it is completely passive, requiring no input of energy.

Go back and read the link:

"Ever-rising temperatures in Qatar which is one of the hottest places on Earth have risen so much that authorities have begun to air condition the open air including streets and outdoor markets...

To cool outdoors

• Giant coolers have been installed alongside pavements and in outdoor shopping malls.
• Small grates beneath each of the 40,000 seats of the open air stadium pushes out cool air at ankle level, resulting in a feel of cool breeze blowing in the stadium..."

You are correct - my bad, thanks.

I got sidetracked watching the video which only addressed painting the roads blue, which seemed like a sensible thing to do.

I agree that running AC outside has got to be really inefficient. It's like cooling your house by opening the fridge door. I guess oil-rich countries don't worry too much about it. I'm wondering where they are dumping the heat.

A Washington Post examination of the fastest-warming places around the world has found that the Magdalen Islands, as they are known in English, have warmed 2.3 degrees Celsius since the late 19th century, twice the global average.

As in New England, Siberia and other global hot spots at higher latitudes, winters here are heating up even more quickly, eclipsing 3 degrees Celsius. That change has fueled freezing and thawing cycles here that wreak havoc on the famous — and famously fragile — sandstone cliffs.

Oops...!

Defying Climate Change, Southeast US Is Getting Colder Instead Of Warmer Via Polar Vortex

These people could use a little warming....

https://www.livescience.com/29913-coldest-places-on-earth.html

"Warming temperatures in the Arctic and melting of Arctic sea ice appear to initiate the movement of the polar vortex southward through a wavier shaped jet stream. The Arctic has warmed twice as fast as the northern mid-latitudes, setting up an imbalance in global circulation."

Keep wishing.

I think they are just guessing, trying to make it fit the narrative....It seems to me the jet stream is just spreading the air around resulting in cooler temperatures in the midwest and warmer temperatures in the arctic region...as well as closing the ozone hole...What's causing it is anybody's guess....

Define "air condition." Is it refrigeration or evaporative cooling.

Or actual air condition, (I.e. removing the humidity) where cooling is a side effect.

Isn't that just a dehumidifier?

Cooling is effected by evaporation of moisture from the body in a dry atmosphere.

Refrigeration cools incoming air, thus removing moisture as a by product of the cool heat exchanger.

I think you have it backwards.

Hence the term ‘air conditioner’

Without digressing to much further,... True to a certain degree....an excerpt from the link.

’Refrigeration first came into common use in some large cities during the late 1800s, typically piped from a central cooling station to meat lockers, keg rooms and even bank vaults where important documents were stored. "Manufactured air,"� as it was known, was primarily an industrial-use phenomenon until the turn of the century, when men like Willis Carrier, an engineer and air conditioning pioneer, began to experiment with systems practical for use in commercial and residential spaces. The key was precise control of the temperature-humidity relationship in the air, achieved by a series of chilled coils that both lowered temperature and the moisture level.’

Yep. If one wants to push something [thermally] uphill, then one is going to need some power to do it.
