"Why not now have a discussion on how to manipulate high and low pressure areas to affect the weather?"

Are we all going to let delusions like this one just sit ?

Who is going to pick this one up ? .... There is significant risk here, in my opinion ...

The public will begin to believe that this fantasy is possible if we just leave statements like this without challenge ..

What about my question?

What about my answer?

Chill weather is not friendly to arthritis. Wait for it.

You may have to wait until you are older to understand this.
The older members understand completely.

And the folk who are moving south tend to be those who can afford A/C.
The term "Snow Birds" is common in Canada.
Summer in Canada and winter somewhere warmer.
Minimum time per year in Canada to maintain Canadian medical coverage factors in.
Snow birds enjoy the best of all worlds.
Not too hot in summer, not too cold in winter, and Canadian medical coverage.
Those who cannot afford two homes and travel between them wear more clothes in winter.

Is the Great Barrier next? Approaching 'sous vide' temperatures...

"An urgent rescue operation is underway to save Florida coral species from extinction as a mass bleaching event and die-off from unprecedented water temperatures spreads across reefs in the the Florida Keys.

Multiple reefs around the Florida Keys are now completely bleached or dead in a grim escalation that took place in as little as two weeks, coral experts told CNN.

Experts now say they expect “complete mortality” of the bleached reefs in just a week, and worry reefs at greater depths could face the same fate if the unprecedented ocean warmth continues to escalate.

Extreme heat and a lack of rain and wind pushed water temperatures around Florida to some of the highest levels ever observed anywhere. A buoy in the Florida Bay hit 101.1 degrees Fahrenheit at a depth of 5 feet Monday, in an area where coral is scant. Many other stations in the area topped 96 degrees, including one that hit 99 degrees, according to the National Data Buoy Center."

A couple of more weeks under the heat dome down south, may start to convince/educate them... and with Florida having 100F oceans, We'll just have to see how this continues...

That poster has a long and storied history of posting ridiculous conspiracy theory BS, and will not respond to criticism. You're welcome to try, but those of us who have interacted with him previously in this and other threads know he won't be convinced. According to him we're all idiots anyway.

A couple of more weeks under the heat dome down south, may start to convince/educate them... and with Florida having 100F oceans, We'll just have to see how this continues...

The fantasy MJC is referring to is enginesrus's BS posts about global warming being due to some master plan by the illuminati, or whatever.

 

[BridgeSmith]

...with Florida having 100F oceans...

Really? You should think about what you write before posting such ridiculous garbage. You'll squander what credibility you have left with statements like that.

 

[TugboatEng]

It was a misinterpretation of some alarmist news that is circulating. There is a shallow bay in Florida that has recently exceeded 100°F due to silt causing additional light absorption. How that result got extrapolate to oceans? I think I know.

[enginesrus]

Something is holding the pressure areas in place. And that is the cause of the heat domes.
My posts are to get the stuff in the heads thinking.

 

[dik]

Sorry Bridge... as noted in the post... you might read some of this stuff...

It's a beginning, Tug, and it will likely get warmer...

from the article, "Extreme heat and a lack of rain and wind pushed water temperatures around Florida to some of the highest levels ever observed anywhere. A buoy in the Florida Bay hit 101.1 degrees Fahrenheit at a depth of 5 feet Monday"

It's likely an effect of climate change on the jet stream...

"A prolonged, unrelenting heat wave has scorched large parts of the South and Southwest United States. Temperatures in Phoenix, Arizona, have hit at least 110 degrees Fahrenheit (43.3C) for a record-breaking 19 consecutive days, and emergency departments are flooded with heat-related illness.

In extreme heat, here are 14 ways to keep your body and home cool without AC
Southern Europe is experiencing one of its most extreme heat waves on record, with wildfires raging in Greece, Spain and Switzerland. And in Asia, temperatures have pushed above 50 degrees Celsius (122 degrees Fahrenheit) in China, while parts of South Korea, Japan and northern India are experiencing deadly flooding.

In a statement on Tuesday, Petteri Taalas, secretary general of the World Meteorological Organization, called this relentless cascade of extreme weather “the new normal.”

But some scientists now baulk at that framing.

“When I hear it, I get a bit crazy because it’s not really the new normal,” said Hannah Cloke, a climate scientist and professor at the University of Reading in the UK. “Until we stop pumping greenhouse gases into the atmosphere we have no idea what the future looks like.”"

Some questions:

How much heating of the ocean is by convection? Or is it as I suspect, entirely heated by solar irradiance? If this is the case, how does climate change contribute to warmer oceans?

About infrared photography, has there been a noticeable change in the brightness of the sky in Infrared photos due to more reflected heat from CO2?

 

[dik]

There are incredible convection currents... all over the oceans.

Convection as in heat exchange from the atmosphere to the ocean. It doesn't make sense that hotter air would convect heat downwards into the ocean.

 

[dik]

As long as you have a thermal gradient within a fluid, you will likely have convection currents whether the fluid is liquid or gaseous. I don't know what the effect of this are if the fluid doesn't change density with temperature. There would be some interaction of the two, by heat transfer, if the two were at different temperatures. This would also affect the convection within the respective fluid.

I know what convection is but you're focusing on the wrong part of the question. I was asking about the heat transfered between the two fluids, the air and the sea. They each experience their own convection and there is conduction at the interface. But, due to the physics of convection I don't believe much heat gets transferred from the atmosphere to the sea as convection transfers heat upwards, not downwards.

And the sea cools primarily by evaporation so the temperature of the air isn't going to have much affect on the cooling of the oceans, either.

How does climate change explain the warming of the oceans?

Are climate scientists so inept that they're assuming the heat transfer to the ocean from the atmosphere is by conduction and are ignoring the convective behavior of the atmosphere?

 

[dik]

I suspect that the more you heat it up, the more it evaporates and the more it cools? Pretty soon there will be ice all over the oceans which will reflect the sunlight and eliminate global warming.

The CO[sub]2[/sub] traps the heat and helps prevent it from radiating into space. This is the greenhouse effect. If the heat is retained against the surface of the earth it will tend to cause it to heat up. This includes both the water surface as well as the land.

It's like putting a pyrex bowl in an over and turning it on. After a short time, the water will heat up. The heat gain is conduction, convection and by radiation. I don't know in what percentages... but, someone may have those figures.

Ok, what what happens when you set the oven for 73°F vs 350°F?

Sorry, you have used a bad analogy. Also, you must know the difference between top and bottom rack. The ocean must be bottom rack.

 

[dik]

Give climate change a chance... it's just beginning. Setting the temperature and the rack location can affect the heating process... but the end result is predictable.
