The Pros And Cons Of Climate Change On Mars
analytical Essay
709 words
Climate Change is the epitome of debate; a vociferous one that has unyielded for the past two decades. This idea is no new thing, originating from Svante Arrhenius who, in 1896, first estimated an increase in the global temperature of Earth as CO2 levels rose. Over the course of a century, Climate Change had received both great opposition and support. The supporters believe that this rise in temperature is caused by humans, while the opposition considers it a natural process. There have been many critiques over this time frame, but there was one that stood out to me. The argument in question supposes that Climate Change is not anthropogenic due to the fact that Mars is warming as well. There are many reasons why this could be considered and why, in the end, it should be dismissed as an argument against a human-caused Climate Change.
Solar activity is considerably related to this issue, in that the opposition would argue that it causes both Earth and Mars to increase in temperature. Even though the Sun is a distinct and straightforward target for Climate Change, ultimately its radiative forcing has been noted to

In this essay, the author
- Explains that climate change is the epitome of debate, originating from svante arrhenius who estimated an increase in the global temperature of earth as co2 levels rose.
- Argues that solar activity causes both earth and mars to increase in temperature. the sun's radiative forcing accounts for less than a tenth of the net forcings of human activities between the years of 1750 and 2005.
- Explains that the opposition would say that mars' climate is warming due to an increase in albedo, but the evidence for warming on mars is based on little empirical evidence at best.
- Argues that fenton's mistake doesn't mean that the 1977 satellite image showed normal albedo levels, not at all. that increase was caused by a previous global dust storm.
- Opines that unless we go to mars and document the warming as we do here on earth, a consensus will likely not be reached.
- Concludes that the opposing argument is false and conjectural due to the fact it is based on fallacious evidence, resulting in an untenable critique.
Unfortunately for them, this is not the case. No, the evidence for warming on Mars is based on little empirical evidence at best. The idea that Mars is warming came from satellite images that were analyzed by Lori K. Fenton. It can be seen from the photos that Mars is darker in 1999 than it was in 1977, meaning a decrease in albedo occurred. These changes in albedo, Fenton calculated, would cause a 0.65°C increase in global temperature over the 22 years. This shift would mean that global warming on Mars didn’t need CO2 to happen, which would credit the opposition. Although, Fenton drew conclusions about climate using two endpoints, ignoring everything in between. This ignorance caused him to make a typical mistake: confusing weather for

Climate change naysayers look more and more foolish every year as more empirical evidence supporting climate change surfaces, and recent reports from NASA do just that. In January of 2016, NASA released data that displayed drastic temperature increases across the globe in 2015. According to their findings, 2015 was the hottest year that has ever been recorded since data began being collected back in 1880. In the last year alone, the average global temperature increased by .23 degrees Fahrenheit. While this may seem like a minuscule figure, one must remember that over the past century the global average temperature has increased by 1.8 degrees Fahrenheit (“NASA, NOAA Analyses Reveal Record-Shattering Global Warm Temperatures in 2015”). The Earth is on a crash course of rapid heating that will prove to be disastrous in the near

- Explains that the government repealed the nationwide 55-mile-per-hour speed limit in 1995, and analyzed the data to determine if there was a direct, causal relationship between the change in speed limits and the frequency of automobile accidents.
- Analyzes the long-term effects of repealing the 1974 national maximum speed limit law in the united states. a 1978 ad council commercial aired on a new york television station discussed the life saving benefit of the speed limit.
- Opines that environmental safety is often overlooked because of the emissions of greenhouse gases, which harm the atmosphere.
- Argues that climate change naysayers look more and more foolish every year as more empirical evidence supports it, and recent reports from nasa show drastic temperature increases across the globe in 2015.
- Explains that 97% of climate scientists agree that climate change is directly related to human activity. the west antarctic ice sheet is in danger of melting faster than previous projections.
- Argues that lowering speed limits in the united states is beneficial to the people of america for a number of reasons.

There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability

There is no enough evidence to disprove the hypothesis. There is no way of telling if the human-induced emissions of CO2 are the sole reason for increase of temperature (global warming) This is due to the fact that the Earth has been constantly and continuously warming since the last glacial period, so there is not enough concrete evidence to disprove that hypothesis. Although human activity may very well be a contribution to the increased temperature, it does not disprove the hypothesis, due to the fact that the Earth is continuing to react after the Ice

- Explains that the historical data that temperature leads to increase of co2 contradicts the hypothesis that recent increases in temperature are caused by the increase in co2.
- Explains that studying earth's climate is much more difficult than studying most other biophysical phenomena because it is being altered by the human race. models are essential for climate to see the past, compare to the present, and predict for the future.

In the natural cause argument, some scientists and climatologists indicate that climate change is due to the natural cycle. First, we cannot definitively prove that man-made factors affect the climate. Second, some studies show evidence that global temperature has changed even before humans. Also, CO2 does not directly impact global warming, and other factors, such as solar irradiance and ocean currents, may have a role. The opposition thinks climate change is all about the natural cycle that is God’s
In this essay, the author
- Explains that solar irradiance and ocean currents' change are natural factors that affect climate change, which is more credible than man-made factors.
- Argues that the evidence and examples give a strong argument against man-made climate change. we don't fully understand the climate, and there are numerous natural factors to consider.
- Argues that climate change isn't man-made, citing the intergovernmental panel on climate change (ipcc).
- Argues that man-made climate change is a myth, and that the opposition thinks it is due to the natural cycle that is god's job.

They do this to turn public attention away from the fact that much of their data is purposely taken out of context, manipulated, or made up in order to prove that Manmade Global Warming exists. In fact, there is more evidence showing that the rise in temperatures may be due to solar activity or part of the Earth’s natural climate fluctuations, than to support that it is caused by greenhouse gases generated by humans.
