I'll judge you by the friends you keep....
In response to the recently trending sound-bytes of Leonardo DiCaprio, an average Hollywood talent at best, taking time away from his lucrative career in order to address the United Nations on his view of climate change, scolding the rest of us for being lousy Earth stewards, I'm feeling a little fired up on a subject that just won't go away. And rather than jumping to my usual response in calling him a hypocritical jackass, I'll approach it with the following....
Let me go on the record first in saying I actually DO believe in climate change. I believe in things I can see and feel directly; things that are tangible and easily documented. Anyone who has lived for at least 15 years and has the ability to look out of a window would agree. Of course the climate changes, silly. It changes every day, week, month, year and so on. And never in the history of our planet has it ever trended in one direction indefinitely without undergoing change. In fact, the changes have often been extreme. Just when you expect another cold winter, along comes a mild one.
"Deniers", as they are called are the boogeyman to environmentalists. They are the straw-man, the monster under your bed, etc. There is no such thing as a climate change "denier" per se. However, agreeing with one another as to what is the root cause for climate change is a completely different discussion.
Now I am sensible enough to realize this argument is not going to go away for a long time for no other reason than the climate change advocates stand to make literally billions of dollars every year by convincing enough people that there is a problem and then proposing a solution for a nominal fee. Others anoint themselves "ambassadors" on the subject and receive heftily lined pockets for speaking engagements on the matter. But the argument technically should die. Why? For two reasons. First, we are powerless to do much if anything about it due to our own meager insignificance in comparison to the size of the Earth, its climate and the primary drivers for its amazingly dynamic ever-changing personality. Secondly, the climate soothsayers are currently batting a perfect .000 in every major prediction they have made over the past 30+ years; everything from the supposed outbreak of acid rain, to all glaciers melting by the early 21st century, ocean levels dropping by over twenty feet to the botched hurricane predictions after Katrina. Why on Earth have we not tagged these people as quacks decades ago and moved on with our lives? Because their pop-culture spokespeople are provided with a continuously renewable supply of adoring and worshipping fans that elevate them to deity status and will willingly hang from every idiotic word that falls from their lips, period. And congratulations to them all. Their blind adoration toward the Hollywood environmentalists has swelled their egos to the point where they truly believe their own emotionally driven opinions, by default, will always trump scientific fact. And they rarely speak in terms of facts, only opinions. A "fact" to one of these people is an opinion they sincerely wish were true, not one that actually is.
A quick review of the facts we know; The Earth has been evolving and undergoing dynamic climate change ever since it first cooled over 4 billion years ago. Sedimentary rock can do wonders to support this evidence while ice core samples or even the analysis of tree rings can do the same to explain more recent events. Continents, via Plate Tectonics move in different directions across the Earth's surface at about the same rate your fingernails grow. Over millions of years, this has lead to dramatically different land masses (large continents, inland seas, mountain ranges, etc.) which can greatly affect climate. Ocean currents and global water temperatures can affect them it well. Also, there are anomalies such as the Earth's rotational wobble cycle which takes some 26,000 years to compete. That has been theorized as to be a major driver for ice ages. Then throw in your solar activity, volcanism, etc. All of these take place on a massive scale - a scale far more massive than little ol' us. The Earth is very large. So are mountains and continents. The Sun is obviously far larger than all of those combined. To think that we are so powerful as a species to have dramatically affected the Earth's climate is a tad on the narcisissitic side. One thing to consider is if you take every human on Earth and stand them all front to back and side by side, they'd all fit within the city limits of Jacksonville, Florida. We are really very small and insignificant in comparison to the Earth and its dramatic geological history. Even if you discount the the time period prior to when the first life forms appeared on Earth, the global temperatures on average, have been MUCH warmer than they are right now. Ice ages are relatively short. In fact, some theorize that we are still technically coming out of the last ice age.
Now I find it perfectly plausible that human energy consumption along with its gaseous byproducts that we have exhausted into the atmosphere for the past 100+ years or so may very well have some measurable affect on the overall climate. Despite my pride in our advancements as a species, I'm not exactly proud of that side effect. But remember, the climate is a sum of ALL contributing factors which most certainly includes many of which I just mentioned. So I have to ask a simple question to those who believe we alone are the sole perpetrators for climate change... "What was causing it before we all got here??" Or at least "What caused it prior to the Industrial Revolution?"
Now that all being said, I am not an excessive energy consumer. I do not drive an RV to work nor do I rent limousines. I go out of my way to recycle whenever possible. I turn off the lights in my house when I leave. I have been transitioning to energy efficient bulbs, I turn off the water when I brush my teeth, etc. It's the little things that all add up. Some call it being a good steward of the Earth, I call it being "unwasteful". I don't like to waste things, be it time, water, energy nor money.
Do you know who IS an excessive energy consumer? Leonardo DiCaprio, that's who. He has multiple homes, rents a super yacht that gets some 1/4 nautical miles to the gallon, flies in private jets and takes gas guzzling limousines to special events all over the world, burning large amounts of fossil fuels so he can tell you and I that we need to burn less fossil fuels.
The exact causes for climate change are far from being 100% known and are thus far from being categorized into scientific "law" by definition. A general consensus of privileged elitist pop-culture icons who stand to make millions of dollars championing the cause will not cut it. And like any other current hypothesis, you will have scientists challenging one another from opposing views. And since the rest of us are NOT scientists, we can choose to listen to those scientists we have the most faith in their sincerity and accuracy. I know which ones I choose.
How do I decide on who to believe? Where do I get MY science? From people that do their research for the common good and knowledge of all, from those that write in text books and magazines in order to educate the next generation, from those whose intent is to share only the facts and the theories they have compiled with his/her own tireless research without attaching a political agenda to it. Not those who stand to receive kickbacks from environmental advocacy groups and the politicians that stand to get elected via their financial support.
So my suggestion would be that if you are aiming to gather international support for your cause, avoid hiring the wolf to be a security consultant at the hen house. And in the mean time, shut the lights off when you leave the house today and don't run the A/C with the windows open.
So in closing, quell your fears and stop bickering. Just as the law of supply and demand encourages problems to solve themselves, the concern with CO2 emissions will as well. The natural progression of energy technology will continue to lean in favor of cheaper, or better yet FREE resources. (wind, solar, geothermal,etc.) Why? Because there is an ever-growing international demand for both greater supplies of energy and increased costs savings, both of which together are known as "free renewable energy". As a result, there is a race among the the potential developers of these technologies to tap that gargantuan market. They are incentivized more than every before to reach it. Even if they are a hapless selfish bastard that is only in it for the money and could care less about the environment, the better result will still be the outcome. It just so happens that this is a rare instance where our desire for self servitude (free stuff) also happens to coincide with what is ultimately best for the environment as a whole. And the best part is aside from cleaning up after yourself and making a concerted effort to not be wasteful, you hardly need to do a thing. There are plenty of engineers and scientists hard at work getting us closer to this solution every day. So perhaps, the next time you wish to blindly deem someone's life's work as "junk science" simply because their data doesn't make you feel very good about yourself, step back and think again.
