Aha, so that is your worldview?
World view = "the world is going to end in 10 years-your going to starve" or "you must stop using fossil fuels if we are going to survive". This doesn't really matter if you think this is a natural cycle, world heats up when it is closest to the sun, the world cools when it is further away. To me that is the logic and not go crazy with your hair on fire thinking, humans fart too much, don't eat meat because cows poop, or fossil fuels cause global warming. Really, some people think that cows are farting too much... or their poo is the cause of human demise. Everything here is organic, part of the world at one time, the molecules that make my body was probably dinosaur poo... its not like we're introducing anything new to the planet. The planet made my fart, made my food, made my air... it is a living and breathing echo system. So, methane has always been a product of the earth, sometimes really high, sometimes really low. A volcano can create as much methane is a couple minutes as we produce in years. Its all about perspective.
"Scientists estimate that volcanoes worldwide emit, on average, about 1.5 million metric tons of CO2 per day (only about 2% of the amount that human activity causes).
Yet that estimate may be far too low because it's based on measurements from only 33 of the world's most volcanically active peaks (only three of which are ice-covered), among the 1500 or so that have erupted in the past 10,000 years. More data gathered from Iceland—as well as Antarctica, which is home to dozens of ice-smothered volcanoes—may help scientists come up with a better estimate for volcanic CO2 emissions."
"Earth has an eccentric orbit, which means that it moves in a path that is slightly oval in shape. Contrary to what you'd expect, Earth gets closest to the sun every December, and farthest from the sun every June. We in the northerhe maximum eccentricity is about 5 percent and the minimum is near zero, when the orbit is nearly circular. This cycle can be calculated for millions of years, and we know that the glaciers also have cycles of about 100,000 years. The question is whether the glaciers are tied to changes in Earth's eccentricity. "
"What is more important to climatic changes over the eons is the fact that the sun is getting brighter. Earth now gets about 20 to 25 percent more sunlight than it did four billion years ago. "
So, blaming us humans on the primitive sources of energy that propelled us from horses to cars in 100 years is the culprit. I doubt it. Until we perfect hydrogen (water base fuel) were going to have to live with the dinosaur fuel. Solar panels are primitive and use more fuel to make them then what they are worth, wind is unpredictable, batteries are nasty... they do more damage to the environment than what they provide in power - my expert (not) opinion.
*** We're clearly not debating about what is good for the earth, but it is a debate about what is good for humans and humans wanting to survive. Because our small brains do not see the big picture. Wish we would stop the bs about the earth... the earth will live on no matter what. This is a debate about a bunch of afraid humans.
So the function is... earth from the sun, speed the earth orbits, natural eco cycles of the earth.
Humans are like a mosquitos to the earth, we're an annoyance, but the earth will be here long after we're gone.
