The global warming on Mars only helps my opinion that warming on Earth is not from people or pollution.

Images were released in mid-September that showed global warming has significantly altered the surface of Mars. Parts of the polar caps of Mars are eroding at an exceptionally fast rate due to a warmer climate.

There are no definite answers as to why this is happening.

I will argue that human-created pollution is not on the list. Since humans obviously do not live on Mars, global warming is affecting the climate of Mars without pollution. If Mars can have global warming without human pollution, perhaps global warming on Earth is being caused by something other than human pollution.

I do not believe global warming to be valid in the way it is commonly presented. If there really is global warming on Earth, it is not because of humans and more likely something that is naturally cyclical.

The argument on Earth is that power plants, cars and cattle are some of the major contributors of gases such as carbon dioxide and methane that create a greenhouse effect.

The other side of the debate is that if there are any effects they could only amount to warmer winters and increased plant growth — which might not be a bad thing. The support discrediting global warming is so apparent that 17,000 U.S. scientists signed the 1998 "Oregon Petition" stating that "There is no convincing scientific evidence that human release of carbon dioxide is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate."

The global warming on Mars only helps my opinion that warming on Earth is not from people or pollution.

The increase in climate on Mars and Earth is not just a coincidence. There is an obvious common link between the two planets. It is the spherical object of fire that accounts for 98 percent of the solar system’s mass.

By all accounts, the sun is more powerful than humanity. It seems that many people think human beings will destroy Earth, but I think it’s more likely Earth — and the solar system — will destroy us before we destroy it. There are so many things that have gone right in order for life, as we know it, to exist on Earth.

In the 1920s a scientist named Milutin Milankovitch proved that Earth temporarily moves out of its orbit around the sun about every 100,000 years. The northern hemisphere could wake up to a snowstorm that would last the rest of our lives with the slightest variation of Earth’s orbit. The slightest tweak in the status quo could make conditions unlivable.

My point is that Earth and the rest of the solar system allowed for human beings to exist here and I believe it’s arrogant to believe we will cause its end. The Earth was around long before now and there is little reason not to believe it will be around long after humanity.

Earth’s relationship with the sun is the likely reason for climate change, not humans and pollution. Just like the relationship between Mars and the sun is likely the answer for its climate change and not Martians.
