Climate change
Definition
I will start with the very basic question of what is climate, it’s not like the weather which is limited to short-term change while climate represents a very long period like 30years or more. From the formation of earth is from the past 4.5 billion years, Earth has gone through many climate changes due to reasons like obliquity (the slight tilting of earth towards the sun) or the impact of a big asteroid, earth has seen ice ages and much mass extinction before. But why we are worried about climate change this time? Is really climate change happening? And finally, are we the direct cause of the catastrophe? I will answer these questions clearly with fundamental examples.
Greenhouse gases
We may get the question heating of the earth is mainly due to the sun, why do we are worried about the greenhouse gases more? Let me take the example of our solar system, the planet Venus is the hottest among all, but it’s not the nearest planet to the sun, if only Sun is the direct reason for the generation of heat mercury should top the list, the reason why Venus is hot It has more greenhouse gas then any planet in our solar system, So we should understand these greenhouse gases are the main reasons for the temperature rise on our earth in past years.
Is Sun getting brighter?
Sun is at his mid-age, another 4.5 billion years and he becomes a red giant, and boom!! Even earth becomes part of him, but it’s after a long time. As the earth is in its declining stage it is not becoming brighter even the studies show that after 1950 sun is getting cooler and cooler, instead of denying our climate change we should accept it and act accordingly.
Reasons for this climate change
The main reason for the climate change is the release of CO2 to the atmosphere the dominant greenhouse gas in the earth’s atmosphere, but here is the catch due to the natural phenomena like volcanoes and all it releases 780GT of CO2 while we humans produce only 30GT of CO2 does that mean humans are not the reason for this climate change? NO here is the reason, even though nature is producing a lot of CO2 in the atmosphere for years it also absorbs the CO2 to the same level that is 780GT, so the extra 30GT that we humans producing is troublesome.
You may get this question how do scientists knew that CO2 produced is from human resources? The simple answer for this isotope is C13 which is not found in natural sources like fossils.
Proof for the climate change
Raise in temperature, after many years of studies showed that the temperature rise follows the path of CO2 releases, so it’s evident that climate change is happening and the reason for it is our industries and vehicles which produce more CO2.
Proof for the rise in temperature
How these scientists are sure of the temperature rise? It can be found by the pattern in sea level raise in years. As temperature increases, the water expands, and ice gets melted and leading to the rise in sea levels, it’s proven that each year sea levels are rising to 3mm. which might sound ridiculous but after a couple of years all the coastal cities will be under water.
Why we don’t act efficiently
The reason behind this is simple, we human beings are grown in such a way that only the immediate threats are taken into consideration, not the long-term calculated catastrophes which might occur in the next century. As one of the rarest and intelligent of all animal kingdoms, we should think twice, and believe the real scientific data and facts and act accordingly, and force our big leaders to take necessary steps.
It’s a very proud moment for me to say that India is one of the countries which promote renewable energy to a large extent and bringing a significant change in the world.
