Three years left to limit warming to 1.5C, leading scientists warn

[westwall]

The mechanism is the sun heats the ocean from the top down.

Provably false. UV penetrates to a depth of 500m. Then.......HEAT RISES.....

Simple physics.

If heat rises then are you arguing the heat is coming from below? Where is this heat rising from? Did it come from the colder waters below?

Let’s see what google has to say.

UV rays can penetrate the ocean to a depth of about 200 meters (656 feet) under ideal conditions, although the intensity of UV radiation decreases significantly with depth. At 3 feet (about 1 meter) below the surface, about 40% of the harmful UV light still reaches. The specific depth of penetration varies depending on factors like water clarity, sun angle, and the wavelength of UV light.

Here's a more detailed breakdown:

• Euphotic Zone:
  This is the upper layer of the ocean where sunlight penetrates and photosynthesis can occur, extending down to about 200 meters.
  
  
• UV Penetration:
  While sunlight can reach 200 meters, the intensity of UV radiation decreases with depth. Shorter wavelength UV light (like UVB) penetrates less deeply than longer wavelength UV light (like UVA).
  
  
• Factors Affecting Penetration:
  Water clarity, the amount of dissolved and suspended particles, and the angle of the sun all influence how far UV rays can penetrate.
  
  
• Coastal vs. Open Ocean:
  UV penetration is generally less in coastal waters due to higher turbidity (cloudiness) and more particles compared to the open ocean.
  
  
• Impact on Marine Life:
  UV radiation can be harmful to marine organisms, particularly phytoplankton, which form the base of the marine food web. However, many organisms have developed protective mechanisms against UV damage.

Yes, are you not paying attention? The UV penetrates all the way to 500m. Notice how that is FAR deeper than the less than one millimeter of penetration your IR is capable of?

It dumps the heat at that depth. Then, in accord with every theory and axiom of physics, the heat rises.

The thermocline is at 700m for a reason.

I just posted the information in my last post. Post yours.

Heat transfers from warmer objects to cooler objects. Ergo heat transfer is occurring from the top down. Excluding convective currents in polar regions of course.

Yes, the link you provided fantasizes about heat being taken deep in defiance of well known physics.

Yes, but heat ALWAYS rises.

So heat is moving from colder objects to warmer objects?

You are confusing heat rising in the ocean with convective currents. Yes, there are convective currents in the polar regions. No, the ocean thermal gradient isn’t due to heat rising. It’s due to the sun heating the ocean and heat transferring into the ocean.

 

[ding]

Yes, but heat ALWAYS rises.

Heat moves from warmer objects to cooler objects. The ocean is being heated by the sun from the top down. The thermal gradient is warmer at the top and colder at the bottom due to heat transfer from the sun.

Where is this heat rising from?

You're starting to sound like that silly guy who always harmed about that. The fact is yes, it does, so long as it rises.

The UV dumps its energy at 500m

 

[EMH]

No, they aren't. Furthermore you can drive down Hwy 395 in California and see plenty of terminal and lateral morraines from the glacial periods.

Here in the Sierra Nevada they have been well documented as to their occurrence time.

When were the last "interglacials?"

 

[ding]

You're starting to sound like that silly guy who always harmed about that. The fact is yes, it does, so long as it rises.

No. Period. Heat moves from warm to cold. How can the ocean not be being heated from the top? Explain that for me.

 

[EMH]

You make opposition to AGW look bad.

No, I threaten your job, by busting CO2 FRAUD, which is the one thing you are MOST OPPOSED TO DOING...

You want CO2 FRAUD to continue.

You cannot refute one word EMH posts.

 

[westwall]

We're in one now.

 

[westwall]

No. Period. Heat moves from warm to cold. How can the ocean not be being heated from the top? Explain that for me.

How can heat descend when physics shows us it rises?

Explain that to the class.

 

[ding]

The UV dumps its energy at 500m

Not according to google. According to google it’s 200 meters and drops off greatly within a couple of meters.

But so what? Why is there a thermal gradient below that? Where is that heat coming from? Because it gets colder the deeper it gets. Are you saying heat is rising from colder waters to warmer waters? That’s idiotic.

 

[EMH]

We're in one now.

And Antarctica and Greenland are growing new ice layers each year, proven by ice cores.

You claim interglacials are when ice contracts on a planetary basis. That is completely disproved by the ice cores, as well as by the indisputable truth that Greenland froze while North America thawed.

You do this because you are a ZIONIST FASCIST FAUX "SKEPTIC" and YOU DO NOT WANT CO2 FRAUD BUSTED because YOU AND YOUR DEMOGRAPHIC ARE BEHIND IT...

 

[ding]

I have. Heat moves from warmer objects to cooler objects.

You seem to be confusing convection for heat transfer.

Can you post a link describing heat rising?
