As always, you are free to believe what you want. The fact is that science is real and there are many venues for scientific exploration and discovery. As far as climate change goes, no I don't believe that there has been a dramatic change in climate over the last 50 years, what I am saying is that there are direct factors that can have a large impact on the climate of this earth. The sun is the single largest influencing factor on our climate, this is distantly followed by our moon and the other planets in the solar system. The sun, being the largest factor, undergoes cyclic changes that have been measured by careful observation. There is the 11 year solar cycle that varies magnetic fields from the sun and results in varying effects of the ionosphere. The sun also has longer duration cycles that can span decades or even centuries. The last solar minimum resulted in a mini ice age somewhere between the early 15th century to around the early to mid 16th century. Global temperatures were lowered and temperatures resulted in a dramatic change in food production. As far as the moon landing goes, I have watched and read many of the theories that the moon landing was fake, once again people are free to believe whatever they want. There are some fairly convincing bits of evidence that a vessel did travel to the moon and did return. Whether or not it contained humans is up for debate, but since the Russians were tracking the object via observatory telescope and radar, it would be difficult to fake an object traveling to the moon and back. The video of the moon landing may have been faked, but dozens of observatories around the world were actively watching whenever they were within line of sight. It is possible to believe that some observatory personnel could be convinced to go along with an elaborate conspiracy theory, however I very much doubt that hostile countries would have been convinced to go along with it, in particular, the former Soviet Union would not let an opportunity to expose a deception of this magnitude and allow the US to claim a scientific coup. There was a race between the Soviets and the US to reach the moon. The Soviets managed to place a dog in orbit before the US could manage the same feat. Needless to say, the evidence for something going to the moon and back is fairly apparent, but this does not rule out the faking of the video imagery or the radio broadcasts. I do not have evidence to support that, and it may very well have been forged, but I am convinced that we did send a vehicle to the moon and it did return. Finally, I actually do work in the scientific fields and have done so since 1993. Considering that I have never faked results and have never had my findings disputed nor been ever asked to alter my processes or results, I do believe that real science does exist, since it has no geopolitical ramifications. There are also many areas within the vast array of scientific disciplines that are not corrupted, and seeing as how atmospheric density can be measure by diffraction of light bending around Venus can lend itself to an accurate reading of change of temperature in the atmosphere, I don't see why you would not believe these results since it has no geopolitical ramifications. So No, I am not naive, simply aware of the processes that can be used to measure a change on another planet within our solar system. By the way, this same method is utilized to determine the makeup of an atmosphere on foreign planets to determine what gases are present.
