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

[Mac-7]

I think it does but it is a supporting role. I think it plays a minor role in temperature changes and a major role in wind patterns. Wind patterns and density differences drive the ocean circulation which is where the majority of heat is.

A minor role?

The sun is the source of all the energy on earth

With respect to the climate changes of the past 3 million years, yes.

Ever since the planet became bipolar glaciated, climate fluctuations and environmental uncertainty are the norm. Given the abrupt nature of these climatic events, the sun is not directly responsible. It’s how the ocean distributes heat to the most climatically sensitive region of the planet; the arctic and the ensuing feedbacks.

What I find interesting is if taken to the extreme, i.e., the Sun stops shining, your system stops in a week.

Yet you claim that it can only have a "minor" role in your system at any other time.

How exactly does that work?

You don’t need math ...

Then it's not science ...

Not entirely true as I can attest by experience by forcing them to prove the following exist:

Lower Troposphere Hot Spot.

Positive Feedback Loop.

They don't try thus their entire LIE is exposed and their delusions exposed.

Don't need math for that.

What do you mean by "Lower Troposphere Hot Spot"? ... do you mean the equator? ... and we use a Positive Feedback Loop to explain cyclogenesis ... or do you mean we can't back it that up with any math if it's a lie? ...

If you did the calculations yourself, you'd see why the poster refutes the need for math ... [giggle] ...

The sun shines just the same when the planet is glaciating or deglaciating. It’s how that radiation is stored and released that explains the climate changes of the planet. Landmass configuration - especially at the polar regions - and how the uneven heating of the surface is manifested by wind and ocean currents and the GHG effect of the atmosphere determines the temperature of the planet.

But the key to our present climate is driven by what is happening in the northern hemisphere. When the northern hemisphere is glaciating, the planet cools. This is because of albedo. When the northern hemisphere is deglaciating, like it is today, the planet warms.

The effect of CO2 is 1C per doubling of CO2. In other words, it reinforces natural warming or cooling. It does not drive it.

 

[ding]

The oxygen isotope curve, which none of you have ever addressed, is most decidedly science. Keep ignoring the empirical climate evidence of the geologic record. See if I care. I’ll just keep throwing it out there because it’s true.

The point is it doesn't. The UV production increases when it's warm, and decreases when it's cold.

Are you arguing that UV production abruptly increases and decreases?

 

[westwall]

Are you arguing that UV production abruptly increases and decreases?

Yeah

 

[ding]

Yeah

Do you have any evidence that supports UV rats as tge cause for abrupt climate changes?

 

[westwall]

Do you have any evidence that supports UV rats as tge cause for abrupt climate changes?

Yes, the fact that UV is the source of the heat in the ocean. It is the only wavelength that can penetrate deeply enough into water to do that.

It is the UV that regulates the temperature of the planet.

You have ZERO EVIDENCE of any "abrupt climate changes" save asteroid hits...

Oxygen isotope curve.

 

[ding]

Yes, the fact that UV is the source of the heat in the ocean. It is the only wavelength that can penetrate deeply enough into water to do that.

The primary wavelengths that warm the ocean are infrared (IR) and visible light, specifically the longer wavelengths within the visible spectrum. These wavelengths are absorbed by the water, increasing the ocean's temperature.

 

[westwall]

That is false. IR is not capable of penetrating the skin of water. Thus it is impossible for it to warm the oceans.

UV is the only wavelength capable of penetrating deep (500m) into the ocean to dump its energy.

That is the source of heat that has over billions of years warmed the oceans.

 

[EMH]

Oxygen isotope curve.

those are volcanic eruptions on the Antarctic Peninsula that the oxygen isotope method of "determining past temperature" gets completely wrong, they are actually up spikes, not down, and because that ONE SINGLE ANTARCTIC ICE CORE you use for "global" temperature gets that wrong, you scream "ice age" or some other complete BS. Downwind of a big volcanic eruption actually warms things quickly, resulting in a spike UP.

YOU CANNOT EVEN BEGIN TO EXPLAIN A SPIKE DOWN....

Why don’t you google it. I have. It’s 100% true. Or better yet post a link showing it’s false. Can you do that?
