For a long time now we have all been hearing that the sky is falling, the climate is changing drastically, the earth is warming up at an alarming rate
and the cause of that is Carbon Dioxide (CO2), in other words, it's man made -bad bad humans. Hence the push toward sustainable energy and banning
vehicles with internal combustion engines in the next few decades.
This is not my theory. This is a theory of a family member who has worked in the nuclear industry and that's about all I will say about that, as it
is a very small industry and not many people have the knowledge this person has. So I would like to try and keep them anonymous. They are also not
aware I am posting this, as I am sure they would personally be put off by this site, but I have spent a lot of time talking to them about this, and to
me - it seems to make sense. At least, in the sense that if we are going to entertain the thought that CO2 is the culprit, we should at least be open
to this likely cause of "global warming".
Now that said, I am not a scientist. I do not have any expertise in nuclear physics or climate science and I am not going to pretend I have a wealth
of knowledge in those departments. However, the person who has shared this theory with me, DOES have a vast amount of knowledge of this topic. So I
will do my best to relay it here. By all means I am open to discussion and criticism, which is why I am posting this here. I certainly have not asked
all the questions that others may think of.
To begin, we have to understand and agree that CO2 is a self correcting system. We all learned around grade 5 science that CO2 is converted into O2 by
plant life, through photosynthesis. This is a fact. We don't like CO2 has humans, we actually exhale CO2 - where plant life inhale CO2 and exhale O2.
There could not be a more symbiotic relationship.
Plant life also uses solar energy (heat/ light) to make this photosynthesis process happen. Over time, as the plant goes through it's lifespan, it
will eventually decay. For plants and even animals who have consumed the plants, which have gone through their lifespans hundreds of millions of years
ago can become fossilized. In the past 100 years we have learned to extract and use these fossils as fuel.
Now, when we burn these fossil fuels, they create not only the CO2 exhaust, but they also create something known as anthropogenic heat.
A quick google search about what anthropogenic heat is finds this:
"Heat released to the atmosphere as a result of human activities, often involving combustion of fuels. Sources include industrial plants, space
heating and cooling, human metabolism, and vehicle exhausts"
The reason for this to occur is because the energy trapped inside the fuel is being released when we burn said fuel, so our cars and planes go weee
and our lights go on in the kitchen from the coal power plants, etc.
Technically, in the sense of former plant life which is now a fossil fuel, it can be summed up as ancient solar energy. The heat has already been
exposed to the atmosphere at one point or another and releasing it back into the atmosphere, should not illicit a drastic change in the stability of
the climate. As for the CO2 that comes along with it, well, so long as we have enough plant life on earth, everything should be stable.
In the case of nuclear energy though, the source of energy is not a fossil. The the energy it contains did not come from life on earth which reaped
the energy benefit from our sun. Uranium, which is used as fuel in nuclear reactors (U235), was formed in supernovas approximately 6 billion years
ago. The radioactive decay in the earths crust can actually account for about half of the earth's heat-flux.
However, the reaction which is caused in a nuclear reaction, like that of a nuclear reactor core, using U235 and tritium (hydrogen -3, a radioactive
isotope) then creates a MASSIVE amount of energy (heat) in respect to the amount of fuel used. Only about 30% of the heat is used to heat up water, in
the boilers, which then create steam to then power the turbines that create electrical energy. The other 70% of the heat created is either sent
directly into the atmosphere as H2O vapor or is transferred into water directly through the cooling systems which are constantly pumping cold water in
and sending hot water back out into the water cycle.
This is where things get interesting. The water cycle, for some reason, has been largely ignored by climate science. They seem to have tunnel vision
in regard to CO2 being the only and most abundant culprit of global warming/ climate change. In fact, H2O is the most abundant greenhouse gas. Which
makes sense, just look out your window and you'll likely see some in the sky, aka clouds. However, if we begin heating up the water cycle with heat
that is not origionally from our sun, would we not be putting more heat into that water cycle which is not "natural"?
Let's think about what those impacts could be. The oceans are big Sparkymedic, how on earth could 200+ nuclear power plants make a global impact?
Well, "nuclear reactions liberate a large amount of energy compared to chemical reactions. One fission event results in the release of about 200 MeV
of energy, or about 3.2 ´ 10-11 watt-seconds. Thus, 3.1 ´ 1010 fissions per second produce 1 W of thermal power. The fission of 1 g of uranium or
plutonium per day liberates about 1 MW. This is the energy equivalent of 3 tons of coal or about 600 gallons of fuel oil per day, which when burned
produces approximately 1/4 tonne of carbon dioxide. (A tonne, or metric ton, is 1000 kg.)"

It's worth noting that these nuclear reactors are generally operating 24/7 worldwide. And have been for many decades now.
How could this massive amount of heat impact the water cycle? Well, if you heat up water, it usually turns into a vapor. That part of the cycle is the
clouds in our atmosphere, and when they get saturated, it rains, pours and sometimes we have hurricanes, tornadoes, blizzards, etc. The more you heat
the water though, the more of it will be in the atmosphere. The water cycle is fragile. You cannot have too much or not enough water in the atmosphere
at one time. Nature has a way of balancing itself. And indeed, CO2 could impact the climate, IF we don't have enough plant life to convert it to
CO2.
So, while this nuclear energy waste heat is technically anthropogenic (caused by humans), the source of that fuel is not the same as oil or other
fossil fuels. The energy that created that oil came from our sun and at one point or another was exposed to our atmosphere and has laready played a
role in the mean atmospheric temperature.
The energy which is released from the nuclear reaction is a totally new source of heat that has never been seen on this planet before. It has never
interreacted with life on earth and it has never been exposed to our atmosphere. Therefore, I suggest that this is a true cause of global warming - if
it is truly man made and not a natural implication of sun cycles.
Again, if we are to believe that all the cars and such on the planet are making an invisible to the naked eye gas, heat up our atmosphere, thereby
causing severe weather, then why would we not consider an unbalanced water cycle caused by nuclear reactor anthropogenic heat?
