This is exemplified by this post: https://patrick.net/1304375/2017-03-27-co2-is-not-the-driver-of-climate-change?1394795#comment-1394795
and all of the other posts like it that spam any discussion on climate change.

Where to start?

First and most important: It is colder in the winter and hotter in the summer. The fact that winter is colder doesn't mean that more heat in the summer wont be bad. This should be obvious.
Second and nearly as important: The CO2 piling up in our atmosphere is cumulative. It provides a constant additional source of heat for the earth, which is slowly heating it up. The heating is accelerating. This is obvious from the theory and it is apparent in the graphs. The IPCC isn't worried about 1 degree rise that we've had. They are worried about the 2 to 4 oC rise predicted (4 to 7 oF).
Third, air temperatures are pretty meaningless. The ocean has absorbed 90% of the heat of global warming. Ice and land have absorbed most of the rest. The atmosphere has negligible heat capacity and heats and cools very easily.

Here are some things that a global average temperature increase might do:
1) melting glaciers and sea level rise: When local temperature swings throughout the year, ice forms in the winter and melts in the summer (locally). If we warm the planet enough, the ice will melt more than it forms, and we are seeing this happen now. The fact that one half of the earth heats up while the other cools throughout the year and ice forms in some areas and melts in others doesn't invalidate the theory that it will melt as the global average temperature increases. This should be obvious.
2) extreme heat events in the US are likely to increase deaths due to stroke, heart attack, etc. Here's from the synthesis report:

There is medium confidence that the observed warming has
increased heat-related human mortality and decreased coldrelated
human mortality in some regions. *Extreme heat events currently
result in increases in mortality and morbidity in North America
(very high confidence)*, and in Europe with impacts that vary according
to people’s age, location and socio-economic factors (high confidence).
{WGII SPM A-1, 11.4.1, Table 23-1, 26.6.1.2}

We are talking thousands, not 10s or hundreds of deaths. It is most probable that climate change has already killed more Americans than terrorism, and we are at the very beginning.
3) In addition to killing people locally, increased heat and water availability issues could (is?) leading to more war. The pentagon consideres this a real threat.

None of these or other threats are proven wrong by the fact that we have seasons with big short lived temperature changes.

And this is where your argument goes completely in the toilet. CO2 does NOT produce HEAT!!!

CO2 absorbs heat that would otherwise be radiated out to space. One might say that it removes part of a heat loss, but it is fine to call absorbing heat that would be removed a 'heat source'. Removal of a heat sink and addition of a heat source are the same thing in an energy balance equation. Stop trying to sound smart. Ironman says

why??

There is no long term 60 degree rise in my backyard. There is an annual 40 oF swing (22 oC) and a daily 20 oF (11oC) swing. These swings have always been there and will not lead to any of the effects predicted by the IPCC.

Do you think that we will not have melting ice and rising sea levels?

Do you think that the daily and yearly temperature changes in VA prove that a 2oC increase in global average temperature will not produce higher sea levels and melting ice?

Do you think that an extra 5-10 oF in hot areas in the summer will not lead to earlier deaths from stroke or heart attack?

Do the cold temperatures experienced during the night and winter show you that?

You have not presented a single argument to show any of these things or anything like that, so it's unclear why you are presenting such obvious factoids as if they are relevant.

No problem with AGW as long as Republican's children suffer.

How much heat does water vapor keep in?

The reason for splitting these myths up into separate threads is to try to get you to discuss each of them and make a cogent argument. Instead, it is your style to just post lots of graphs that you cannot interpret and move on. Let's focus on this one.

Ironman says

How much ice is in your backyard in July versus January??

This is not a concern. Why would it be? What impact does this have on ocean levels or global average ice extents?

The rest of your comment is basically stating over and over again that the sun is the source of energy on our planet. While true, this doesn't mean what you seem to think it does.

Ironman says

Why is that?? Is it because they can see that you're a nut case??

Or nobody is willing to try to defend your ridiculous assertions.

So if that's the case, how does the atmosphere transfer the heat to the oceans, since it's just laying on the surface of the water? How does CO2 in the atmosphere make the water warmer?

Again, you are avoiding the topic. You seem to be picking up information in the other thread with an article by an industrial chemist. It's a completely crap article. Heat is transferred by radiation, convection, and conduction. Air is not just laying on the surface of the water. The air mixes, and the water does too (convection). They can radiate to each other. There can be conduction through a boundary, but conduction really just describes heat transfer in each layer. The boundary conditions are that the temperature is the same at the air / water interface and that the flux is equal. If his problem is that conduction would be slow through the ocean, then he's neglecting ocean currents and assuming that the ocean would all have to achieve the same temperature. If the ocean conducted heat less, then the surface ocean temperature would rise more quickly as it is heated, not less quickly.

Heat and mass transfer is the subject matter of chemical engineering, which I have a PhD in. It's also something that you simply don't understand.

I'd love to see this idiot get into the senate and then try to question climate scientists on the senate floor. That would be pretty funny.

Ironman says

So, a chemical engineer is an expert climatologist??

A chemical engineer knows more about heat transfer than a chemist, and certainly more than you. Go look up chemical engineering curricula, and you will see lots of courses on heat and mass transfer as well as thermodynamics. You seem confused about this.

6   FNWGMOBDVZXDNW   2017 Mar 30, 12:40pm  

Ironman says

What is the ORIGINAL SOURCE

Irrelevant. We've been down this road before. In fact, I addressed it in post 7 of this thread.

7   FNWGMOBDVZXDNW   2017 Mar 30, 12:42pm  

A chemical engineer isn't a climatologist, but I never claimed to be a climatologist. I did claim to know about heat transfer. That's why I'm telling you to go look at the curricula. It's important, because you are getting fooled by the article listed in this thread: https://patrick.net/1304501/2017-03-30-chemistry-expert-carbon-dioxide-cant-cause-global-warming. You simply don't have the toolset to evaluate it.

https://en.m.wikipedia.org/wiki/The_Blob_(Pacific_Ocean)

This is a dujuer favorite on the conspiracy web.

Since no one can explain the phenomenon, the theory is that this giant hot water pocket was created by US govt to mimic global warming.

I'm not saying I believe them, but wth is scientific explanation of the blob?

9   FNWGMOBDVZXDNW   2017 Mar 30, 12:44pm  

Ironman says

So if the sun disappears tomorrow, all the abundant CO2 in the atmosphere will keep us all warm?? Is that your assertion???

No. The sun heats the earth. CO2 and other greenhouse gases trap heat when the earth radiates it back to other objects. Everybody knows this.

10   FNWGMOBDVZXDNW   2017 Mar 30, 12:49pm  

Hater says

What do you think the sun does?

Ironman thinks that because the sun is the source of energy on earth that nothing else can warm the earth (cause the temperature to increase). We all agree that the sun warms the earth, but other things can cause the earth temperature to go up. What ironman doesn't seem to admit is that the earth radiates heat back to space and that gases can interfere with this process.

11   FNWGMOBDVZXDNW   2017 Mar 30, 1:07pm  

Hater says

What other objects?

Other planets or debris in space. Radiation is interesting, because it just needs a clear line of site. It doens't need something to be close by. All of the heat absorbed by the sun is balanced by heat radiated back to space. If that didn't happen, conservation of energy would require that the earth heat up indefinitely. This is literally called 'the first law of thermodynamics.'

12   FNWGMOBDVZXDNW   2017 Mar 30, 1:11pm  

Ironman says

So, does CO2 replace that NET heat loss the next day??

No. CO2 reduces the net loss at night and increases the net gain during the day. This is simple stuff. Everyone who has a basic understanding of how this works already knows that the part of the earth that is experiencing night (pointed away from the sun) has a net heat loss. Of course, the other side of the planet is heating, so there is no period of time when the earth is on balance experiencing a big net loss. I say big, because there are always minor fluctuations due to random things, but those cancel each other out.

13   FNWGMOBDVZXDNW   2017 Mar 30, 1:15pm  

Ironman says

Hmmm, like radiational cooling?

You bring this up like I don't know what radiation heat transfer is. But, you can find me discussing it in this thread in comments 3 and 11. In comment 3 I even discussed how CO2 reduces the heat loss from radiation.

14   FNWGMOBDVZXDNW   2017 Mar 30, 2:23pm  

Ironman says

So, a 20 to 30 degree change from day to night is just a "minor" fluctuation from random things?

No. I never said that. I said that the other side of the planet was heating, so on average there is no period of time when the earth is cooling. You might not know this, but there is no daytime and nighttime for the planet earth. Other than lunar eclipses, it is always sitting in the sun. When the temperature drops at 'night', that is a local phenomenon.

Here's the quote. Maybe you missed the 'on balance' part. The explanation of what is happening on the other side of the planet is there. Did you read and understand it?

YesYNot says

Of course, the other side of the planet is heating, so there is no period of time when the earth is on balance experiencing a big net loss.

You don't... post after post of yours proves that.

You are too ignorant to understand most of my posts. This is evident by your poor reading comprehension.
