Wow a lot to unpack here.
I am a realistic environmentalist and have a very scientific background of education - at least to the extent that I can usually determine B.S. when I hear it.
Interesting. I too didn't know what to believe about global warming several years ago. Having a solid educational and work background in science, I felt comfortable taking a look at the mainstream science to see if there was anything incomplete or outright incorrect about their conclusions
So, I guess that is a very subjective point of view and I totally admit to that. My personal experience trying to talk and discuss this subject with all the "doom sayers" over the years is they are similar to the old character saying "the sky is falling". They are so convinced that the dogma, opinion, and "science" they have been subjected to is unequivocally correct that it cannot be questioned. I find them to be like religious zealots.
This appears to be a solid misunderstanding of how science works on your part. The basic science behind climate change is unequivocal. It's the same thermodynamics and heat and mass transfer taught to engineers and scientists at any decent university.
You won't find many climate scientists disagreeing with the fundamentals. Just like you won't find many physicists challenging basic tenets of Relativity or Quantum Mechanics.
People who refuse to entertain the notion that climate change isn't happening or isn't currently caused by man aren't holding that position due to faith. They are holding it due to
evidence. The evidence does not support a model of the climate where we are cooling or where the warming is from something other than the insulative properties of CO2.
The simplest check to determine whether the Earth is warming is to measure the energy flux from the sun and compare it to the energy flux leaving the earth. To be in thermodynamic equilibrium they have to average out to being equal.
- We have satellites that measure solar flux
- We have satellites that measure energy leaving the Earth
- They suggest an imbalance where the Earth is gainning ~0.5W/m^2
- The uncertainty of the measurements is such that while unlikely, it could be in energy balance
So to verify warming we perform an energy balance by counting joules stored in and measuring the temperature of the atmosphere, oceans and land.
- Satellite estimates of the stratosphere show cooling as predicted by mainstream climate science. Less energy is escaping Earth
- Satellite estimates of the Mid-troposphere show a slowly increasing temperature. This is where the so called "Pause" was measured.
- Ground stations measured rapidly increasing atmospheric temperatures even after calibrations for heat island effects
- Argo Floats and ships have measured significant changes in ocean heat content, equivalent to ~ 200 A-bombs per minute every minute over the last 40 years. This is where about 90% of the imbalance has been stored
This evidence confirms warming. Other evidence includes sea level rise, increasing tidal flooding of Florida and other low level areas, and loss of Artic, Greenland and Antarctic ice sheets. These were all predicted by mainstream climate science.
To connect it to our activity we have to posit where all this extra thermal energy is coming from.
Satellite measurements show over the last 40 years it has not come from the Sun. Latent heat of formation of the Earth and radioactive decay of isotopes in the Earth cannot suddenly increase warming.
That leaves the greenhouse effect. Scientist have known for over a century which atmospheric gases are transparent to infrared and which are opaque.
- CO2
- H20
- Methane
- Other trace gasses
CO2, methane and other trace gasses are released by human activities. Water vapor increases as atmospheric temperature increases.
We know the makeup of the atmosphere and how these gasses are increasing.
CO2 is only likely culprit, with smaller forcings for Methane and other trace gasses
Now it could be possible that CO2 was mostly coming from natural sources. However CO2 that comes from natural sources has measurable amounts of radioactive Carbon isotopes in it. Fossil fuels do not. So it can be confirmed that the increase in CO2 is coming from fossil fuels. (Not to mention the markets track all fossil fuels bought and sold and we know the chemistry behind combustion).
Even if we compare today vs other times in history when CO2 has been higher, the rate of temperature change is ~10 times faster than any other time in history.
I suggest checking out the American Chemical Society Climate Toolkit to understand most of this better.

I remember back int he 1970-80's we were supposed to be in a cooling trend and "experts" talked of a coming ice age that was imminent. Then Al Gore convinced millions that " the earth has a fever" and produced his very fake "documentary" thru CGI and the wonders of cinema. Now it is no longer called global warming - but "climate change" and every tornado, hurricane, or any other natural phenomenon that happens is because of "climate change".
That's being misremembered on your part. While the media played it up as global cooling, mainstream climate science did not.
The story was based on new at the time analysis of particulate pollution and the cooling effect it provided. The science quickly showed it would slow warming but not halt it.
(The pollution also caused acid rain)
Nothing in an inconvenient truth is substantially at odds with climate science or the evidence. Al Gore is not a wizard who makes CO2 trap heat.
However, on the other hand, you don't have to be a grazed alarmist to take note that winters in the northern half of the USA (where I live) are not what they used to be - so ya - the climate has changed/warmed a bit over the past 50 years form my perspective.
So if you are noticing changes why are you so skeptical of the evidence supporting the science behind why those changes are occurring.
The issue that I have is the supposed "science" saying the climate change is due to to "human activity". If you Google "climate change science" - it is not hard to find differing opinions on it. Yet , many say , the science is conclusive and that 97% of scientists say - blah, blah, blah. So, weather you like it of not- there is differing opinions in the science community on the causes of the climate.
Again, the evidence supports the 97%. When the 3% have a model that can accommodate all the evidence, including the warming effect of CO2 AND make better predictions than the mainstream it will become the mainstream. Not until then.
So whether you like it or not opinions that cannot be backed by evidence and theory are not science.
Do I like Trump= NOPE. However, the alternative was even worse in my opinion - because I think Trump will be checked , rechecked, scrutinized, blocked, etc. much more than Hillary would have been. So, he will be unable to implement much of what he wants - heck half of his own party is undermining him. Here is an example of a "science website" that disagrees with much of what the 97% agree upon.
https://www.friendsofscience.org/index.php?id=3 -
That "science" site is funded by oil and gas companies from what I could find. They also don't appear to have many if any peer reviewed published climate scientists on staff.
Why would you trust them?
so I am on the fence on the global warming/climate change issue overall and just like the last several presidents - Trump can and will fire/appoint positions as he wills. He was duly elected and we have to deal with it.
So at the start you had this hypothesis that you could detect BS with your science background.
I think from by the fact you are still on the fence and citing sketchy sources fails that hypothesis.
