Climate Change Exists
Climate change exists. There is lots of evidence to prove it. What there isn't is a lot of evidence that we can actually do anything about it. I don't mean to say that humans are not contributing to the pace of global warming, or that we shouldn't take steps to protect the environment so that we can continue to prosper as a species, because we are and we should. Pollution, deforestation, exploitation of resources and loss of species are all serious issues, my point is this:
The forces that cause climate change are so far beyond the scope of human intervention that it's use as a political rallying cry is little more than chicken little crying, "the sky is falling", meant to inspire fear and a sense that we can do something about it. The reality is, we can't stop it, we need to recognize it for what it is, accept it and prepare for it.
Following you will find my two argument to prove the reality of climate change, and 7 reasons why there is nothing we can do about it.
The Ice Ages Prove Climate Change Is Real
Two Words That Prove Climate Change Is Real
The only argument it takes to slam the reality of climate change into focus are the words Ice and Age. An Ice Age, by definition, is a long term period of reduction in the temperature of the Earth's surface and atmosphere resulting in the advance of the polar ice sheets and glaciation at high altitudes. A long term period of the reduction in the Earth's temperature during which ice dominates the land, a time of changing climate.
Over the course of the Earth's history there have been at least 5 major ice ages. The latest of which is called the Pleistocene Epoch, also known as "The Ice Age" and associated with the rise and spread of mankind, a period of glaciation which began about 2.6 million years ago.
There is a lot of evidence to support the advance and retreat of glaciation and the concept of "ice ages". These include geological, chemical and paleontological. Geological evidence is things like scrapes, scouring and deposits of rocks and plants left behind by advancing and retreating sheets of ice. Chemical evidence includes ratios of isotopes found within are trapped in ice, the water itself and biological specimens found in situ. Paleontological evidence includes the distribution and spread of fossils before, during and following periods of glaciation.
We are currently in the Holecene Epoch/Age of the Quaternary system, an interglacial period at the tail end of the Pleistocene. Interglacial periods are times of intermittent warming within a longer term ice age, a period of documented climate change that has been ongoing for millennia. By this measure alone the concept of global warming is indeed a reality,the Earth is in an interglacial period of warming lasting thousands of years.
Another reality is that, based on the fossil and geological record, the Earth has spent more time with no ice than it has with ice. By that measure the current shift to a warmer climate is a normalization of temperature and not the shift to extreme that some would lead the public to believe.
Ice Ages Are Documented Periods Of Climate Change
7 Reasons Why We Have No Control Over Climate Change
Again, I am not tying to say that we as humans should not fight to keep control of our environment, only that the energy spent on the issue of "climate change" would be better spent on issues like the ongoing deforestation of rain forests, over-harvesting of the oceans and pollution. The following list of facts, seperately and in tandem, show how the factors that bear the most impact on the climate of the Earth are out of our control. To try and alter them is akin to a single person standing in front of a tidal wave with their hands out shouting, "stop!"
The Earth's Orbit Around The Sun, Part 1
The Earth's orbit around the sun is elliptical. The Earth's orbit is in the shape of an oval with the Sun closer to one end, the focus. This means that throughout the course of a year the planet we live on is closer to or further from the Sun. By itself it is one of the primary factors that cause the changing of the seasons. On average the Earth is about 93 million miles away, the closest it gets is about 90 million miles. When the Earth is closer the Suns rays are tightly focuses and warmer, when further away the rays are more diffuse and cooler.
A Standard Earth Orbit
The Earth's Orbit Around The Sun, Part 2
The Earth's orbit around the Sun is not a perfect Ellipse, that is, it is not a constant Ellipse. Gravitional factors including the Sun, the Earth, the Moon's orbit of the Earth, the affects of the other planets as they orbit the Sun and other extraterrestrial impacts result in variation in the Earth's orbit around the Sun akin to the pattern made by a Spirograph toy. Slowly, on a year by year basis, the shape of the Ellipse changes so that it is narrower or wider, with the Earth a little closer or a little further away from the Sun, slowly affecting the surface temperature as it does so.
The Earth, The Sun, The Planets Affect Climate Change
The Earth's Speed Around The Sun
The Earth's speed around the Sun is not constant. As the Earth moves closer to the Sun it speeds up, as it moves further away it slows down. The point of maximum speed is when the Earth is the closest to the Sun, the point of minimum speed is when the Earth is nearest the Sun. This phenomena is also responsible for the changing of the seasons. Counter intuitively, winter is when the Earth is closest to the Sun but moving past it at the fastest rate, summer is when the Earth is the furthest away but slow enough for the Sun's ray to warm it.
The Earth's Rotation On Its Axis
The Earth's rotation on it's axis, and in particular the tilt of the axis, is another primary cause for the changing of the seasons. The changing of the seasons is in itself a measured short term climate change. Throughout the course of the year, as the Earth orbits the Sun with its variable ellipse, the Earth is either tilted toward or away from the Sun, it is summer in your hemisphere when the Earth is tilted toward the Sun and it is winter when it is tilted away from the Sun. What makes this really interesting is that the Earth's tilt is not stable either, and that has a great affect on the temperature of the surface, the direction and rate of climate change.
The Earth Is Tilted
The Earth's Rotation On Its Axis Is Not Constant, Part 1
The speed at which the Earth rotates on its axis is not constant. As the Earth moves closer toward the Sun the speed of rotation increases, as the Earth moves further away from the sun the rate of speed decreases. The rate of spin affects the temperature of the surface by allowing the Sun to cook one spot on the surface for longer or shorter a time. To witness this affect just look to any food roasting on a spit. When the spit turns slower the food roasts evenly, if the spit turns to slow hot spots form and you run the risk of burning.
The Earth's Rotation On Its Axis Is Not Constant, Part Two.
Not only does the Earth's axis have tilt, it has wobble. This means that over the course of time, on a year to year basis, the tilt of the Earth changes. Sometimes it is tilted closer to the sun, sometimes it is tilted closer to the sun. When it is tilted closer summers are hotter and winters are colder, when it is tilted further away summers and winters are both milder. An Earth tilted closer to the Sun and moving slower around it runs an even higher risk of getting burned in an isolated region such as a polar ice cap.
The Earth Wobbles On Its Axis
The Earth's Rotation On Its Axis Is Not Constant, Part Three
Not only does the Earth rotate on a wobbly axis while it travels around the sun in a variable elliptical orbit the axis itself changes. Imagine first a needle with a drop of water frozen to it. The needle is the axis, the frozen droplet the Earth. When the axis moves the Earth moves in tandem. Now imagine that the droplet is not frozen, and that when the axis moves the Earth moves with it, but not quite exactly in tandem like it would it were fixed in place. The furthest measured shift from true north the axis has ever made was 37FT. This effect does not have much bearing on our daily lives but it does impact things like GPS, satellites, observatories and navigation. It also affects which areas are pointed closest to the Sun as the Earth travels through space, and which areas are most likely to become hot/cold spots. Scientists with NASA and the Jet Propulsion Laboratory have proven that changes in the distribution of water have a direct affect on changes in the location of the axis of spin.
The Axis Shifts
The Evidence Is Clear, For An Astrophysicist
I'm no astrophysicist and no mathematician. The calculus needed to describe the factors as I have laid them out is complex to say the least and far beyond my ability. Regardless, I think it clear that climate change does exist, and that the factors that go into what truly causes it are far beyond our ability to affect. In terms of the cycle of climate change yes, we are in a period of global warming but it is one that began thousands of years ago, driven by cosmological factors, and one that will continue on into the next millennia.
- The Earth's climate is the sum total of factors resulting in the angle of the Earth as it travels through space, the speed at which it is traveling and rotating, its proximity to the Sun and the exact spot at which the Suns rays are focused. Over time these factors affect the average temperature of the Earth's surface by altering the length of the seasons and warming affects of the Suns rays which in turn have led to numerous changes in climate over the course of the last 4.6 billion years.
Climate Change, Is It Real?
They Are Still Cutting Down The Rain Forests, FYI
Tilting At Windmills
To focus efforts on an issue as impossible to effect as "climate change" is little more than tilting at windmills. A better use of such energy might be the push to maintain and manage the environment as it changes naturally, over time, as it will whether we want it to or not. This means conservation of natural areas such as rain forests and oceans which, ironically and unfortunately, have fallen out of vogue among the media. The Earth is our habitat, we need to care for it and manage it so that it will continue to provide and if that means adjusting and adapting to changing conditions that's what needs to be done.
Preparation is really what we need to do. Climate change is real, its not stopping and will last for thousands if not millions of years. If we don't accept it and get ready then it might just steamroll us all into extinction, all while protesters march and chant about how we need to stop it.
