Is there an objective reality we can consider? For example if we assume there are two sets of facts for every argument which is correct? The easy answer is yes. The one that can be tested and the tests can be repeated getting the same results is the answer.
Except people believe that other people cheat on the testing. IE, I personally am the objective reality and am able to discern who is cheating the testing and therefore I can reject that data. It is an interesting problem and one that you probably encounter more than you realize. I called this phenomena “Ilackasourcism” a number of years ago. It is in the end a fairly considerable problem.
First off studies that publish data are more credible than beliefs and well suppositions that people have. A valid tested set of data has merit. Let’s take a fairly easy problem. The ocean is comprised of salt water. That can be easily tested. You go to the beach (oh wait, fresh water lakes like Superior are large and have beaches, we need to be specific here). Ok you go to a beach that is directly connected to one of the Oceans of the world. Not a major lake or body of fresh water with a sandy beach. Let’s say that its stipulated that you have to be near an ocean such as the Atlantic, Pacific, Antarctic or Indian. You then draw a cup of water while on that beach. You can use any number of tests to prove it is salt water. Let’s say you taste it (is it salty?). We can argue if you use this model that in fact your taste buds are wrong and therefore it isn’t salty.
We can also dive into the science of testing for salt. Put lead (II) nitrate, Pb(NO3)2 in there, or any kind of soluble lead (II) compound. The lead (II) will bond with the chloride ions (assuming this is NaCl), and form a PbCl2 precipitate, which is visibly recognizable.
If you want to know how much salt, weigh the amount of PbCl2 you have, and then use stoichiometric ratios in the following reaction:
2NaCl(aq) + Pb(NO3)2(aq) —> 2NaNO3(aq) + PbCl2(s)
Now we can take the water, seal it in a container and using tape or some other modality guarantee that it isn’t opened before we take it to another person who runs the tests above and verifies that it is salty water.
Based on the above you can’t argue that in fact the water isn’t salty. 100 people can run the same test on the same water from the same location or any one of 100000000000000 other locations near one of the oceans of the world and get the exact same results. Salt water.
So how is it in the end, without credible tests and without verifiable data bunches of people that are not scientist say global warming is a myth? That in fact global warming is a natural process (it is) that hasn’t been modified or changed by human gas production (umm…where did the CO2 come from Giraffes?). I would like to see a test that shows Co2 is actually produced by farting Giraffes. That would be an interesting test. There is no climate change caused by humans it is all caused by farting giraffe’s and burping sharks.
The data is in. You can test the data. We can send people to Antarctica and have them core ice and pull up ice from a million years ago and test the presence of CO2. Folks it is radically different. We can test 100 different ways and in the end show that in the last 100 years the impact of humans on the environment is so massive that we have changed the very fragile ecosystem we depend on to survive.
Now you get my favorite argument in response to the scientific data. Global Warming is a myth. It was colder this winter than it has been in the past 20 years.
Climate change produced by CO2 gases has to do with the amount of energy either absorbed or last from the sun. Based on the ultimately easily tested information about how much energy is or isn’t captured by the earth from the sun we can quickly and easily determine if there is a difference. Why is the climate change so bad? First off you get more super storms. Super storms are game changers and impact the world more than normal storms do. There are normally 1-2 super storms per time period as determined by historical records. The number of super storms around the world has increased to levels never before seen. That happens from energy. Once energy is created it has to be used. The earth is not a huge space battery. That energy produces heat in one place that evaporates water. That water enters the atmosphere and moves to another location. It can then cool the atmosphere around it and produce colder temperatures. Or because it is hot, has energy, and is in the atmosphere it can modify where it goes.
It saddens me that the science is out there. You can do the experiments yourself. You can gather all the data yourself and see that climate change is happening. Or you can listen to media outlets that proclaim scientists are lying to us because they are going to gain financially from the research grants given to them to study climate change. Argue both sides of this. Look at the conservative view. There is no climate change. Look at the liberal view, humans caused climate change. Throw both of those away and test the data yourself. No one can manipulate your test results but you. If you intentionally sabotage testing to get the results you want then shame on you.
Climate Change is real. It is happening. It is going to get worse.
