Like most Trump haters you miss the point completely. Way over your head.
Yes, it's more about Trump having
common sense, and because he is his own man,
being able to speak up and challenge the increasingly out of whack modern dogmas.
His critics get caught up on stuff like the hair spay rant or his personal style,
missing the big picture, because they haven't spent the time or lack the
critical skills to deconstruct the established narrative.
I think we should give guys like Pants some leeway, provided they're not trolling,
because the transition from blue to red pill takes a good deal of work.
There is a lot of propaganda to undo.

It's all good Pants. Here's the short answer on the question:
-human made CO2 is only 4% of total CO2, and it's been growing
steadily well before human CO2 became important. At this point
the greenhouse effect from any extra CO2 is very marginal, because
that effect is limited to a very narrow wave spectrum band. Here is
the relationship between additional CO2 and warming effect:
I had a brief look through your post, and i will find some time to look on the video/webpage with time.
However the first statement, what do you mean by 4%? Before humans started to extract fossile fuel. The amount was below 300 ppm according to samples. Now its above 400 ppm. Where does 4% come in?

First, the ice core measurements, which are the CO2 measurements
most widely used by warmists and the IPCC, aren't as reliable as proxies
for historic CO2 levels. Here are two different data sets, the first one is
from stomatal measurements in Mt. Rainier (Washington State) pine needles
(Kouwenberg study, 2004):

Some have asserted that there is no geological precedent;
claiming atmospheric CO2 concentrations have risen faster in the last
150 years than at any time in recent geological history. Ice core-derived
CO2 data certainly do indicate that CO2 has not risen above ~310 ppmv
at any point in the last 600,000 years and that it varies little at the decade
or century scale. However, there are other methods for estimating past
atmospheric CO2 concentrations.
Plants “breathe” CO2 through microscopic epidermal pores called stomata.
The density of plant stomata varies inversely with the atmospheric partial
pressure of CO2. Several recent studies of plant stomata from living,
herbarium and fossil samples of plant tissue have shown that atmospheric
CO2 fluctuations comparable to that seen in the industrial era have been
fairly common throughout the Holocene and Recent times.
Plant stomata measurements reveal large variations in atmospheric CO2
concentrations over the tast 2,000 years that are not apparent in
ice core data

Here is another CO2 historic series, based on 200,000 data points
from the last 200 years:
http://www.biomind.de/realCO2/
Notice that if CO2 falls below 200ppm, plants barely have
enough CO2 to survive. If those levels dropped to 150ppm range,
nearly all crops would collapse and the world would starve...
The increse in CO2 has been a tremendous boon to humanity,
the warmists are panicking over the rise from 300ppm to 400ppm,
when in fact further increases would be great. People who run
greenhouses boost their CO2 levels to around 1,000ppm to
maximize plant growth. Without this, you could barely grow
tomatoes in Holland during winter.
In the past, CO2 levels have been as high as 4,000ppm without any adverse
effects to plants or animals, some of which like the horseshoe crab have not
changed since, so the ocean acidification alarmism is also a canard.
As to the proportion of human-made CO2, here is a graph taken from
the IPCC (the gospel of alarmist global warming) that gives you a visual
representation of the CO2 cycle, putting human and natural sources side by side:
