Earth’s Day – PART ONE: THE PROBLEM!

Earth’s Climate Change.

When thinking about earth, one almost seem puzzled and begins to wonder. Why are we still looking for similar planet whereas we humans are unable to save ours? I’m glad today I have the opportunity to talk about this issue since Earth’s Day has arrived.

Unfortunately, we can easily notice the mysterious changes taking place on Earth everyday and even every second. I really thank God for those few remaining trees that are striving to bring us oxygen while waiting for someone to tear them out and establish a building instead. Has anyone noticed how dusty is it the air we’re breathing to our lungs? Didn’t you notice how many water sources turned polluted? And how extremely cold our winter comes? And how extremely hot our summer became?

CO2 Emissions Have Huge Consequences.

Away from despair, let’s talk scientifically; Beginning with greenhouse emissions, NASA revealed the latest data measurement for CO2 which is the primary greenhouse gas that is contributing to climate change. Records indicate a level of 405.6 ppm on March 17 this year. Many people may not understand what this means unless they take a closer look to the published graphs.

The real shock comes when examining how big a change has been since 1950 up till today. Regular levels are shown briefly in the historical graphs to be in the range of approximately a hair under 300 ppm and down to 180 ppm. Major causes of increase in carbon dioxide concentrations burning fossil fuels and oil which started from the industrial revolution in 18th century and kept increasing under excessive use and dependency on oil applications (cars, machines, etc.) up till now. What is more scary is the spark in the graph from 1950 till today. So imagine this rapid increase will stay the same till 2050, what kind of life will our grandsons witness?

Sea Rise Is Another Aspect.

On the other hand, studies at NASA show 88.2 mm sea rise this year – highest level ever reached – with 3.4 mm rate of change annually. Going back to the 90s, one can easily see how severe the change has been. In nearly year 2000, rise in sea level shows 25 mm sea height. Melting ice sheets and glaciers in both poles along with rise in ocean temperature are the main causes. But the cause behind all of this is the increase in Global Temperature that we’re going to discuss next.

Latest annual average of change in global temperature presents a level of 0.99 ºC which is the highest among all previous years. Reasons behind the rise of global temperature are excessive use of fossil fuels, deforestation, and many other human activities.

Connecting things to each other, we conclude that the major causes of climate change are human misuse of resources, specifically the expansion of greenhouse gases. The sun is in no way to be blamed for the increase in global warming. Referring to data collected by satellites since 1978 and analyzed by NASA, irradiance from sun is responsible for no more than 10% of 2oth century’s warming. Even volcanoes which are large emitters of carbon dioxide emits 1/135 what is emitted by human applications.
