Most of you must have heard that a debate is going on whether climate change is a myth or a reality. There is no denying the fact that our climate is deteriorating due to our own activities. It is clear that if these activities are not checked then the earth will be in real danger and will no longer be able to support life. Most of the publications are suggesting that few people are denying the climate change reality to put their short-term economic interests above the continuation of life on Earth. They are creating and spreading these false denials of climate change.
What is climate change?
It refers to wide range of global phenomena created by burning of fossil fuels. As you must be aware of the fact that burning of the fossil fuels lead to the emission of greenhouse gases like carbon dioxide, Methane, Nitrous oxide, Chlorofluorocarbons, etc. These gases have the ability to trap the sun’s radiation which would may reflect back otherwise, causing rise in the global earth’s temperature. This gradually increase in temperature is bringing forth changes like sea level rise; ice mass loss in Greenland, Antarctica, the Arctic and mountain glaciers worldwide; shifts in flower/plant blooming; and extreme weather events. Thus, disturbing the overall ecological balance.
What are the main indicators of Climate Change?
This is certainly the most pertinent question as climate had also been changing in past. The earth’s history is clearly indicating that the climate has varied, sometimes considerably. So what’s new in this? It is scientifically proven that atmospheric CO2 has increased dramatically since the Industrial Revolution. As greenhouse gas emissions from energy production, industry and vehicles have increased, temperatures have climbed, and showing highest anomalies in the past few years.
Extreme Weather Patterns
Scientists believe that temperature rise will lead to more extreme weather patterns such as hurricanes, drought and intense rain. The arctic begins to melt and send fresher waters further south. The melting glaciers will contribute towards the rising sea level, thus increase flooding.
Most of the trapped heat in the atmosphere is absorbed by the oceans. Owing to this, the temperatures of the oceans are also rising. Due to this, various other ecological changes are taking place suffocating oceans. The solubility of oxygen in warm water is less. So, oxygen deficit regions in oceans are increasing at faster pace and oceans are suffocating. The shortage of oxygen is adversely affecting the marine life, thus disturbing the overall ecological balance.
Increasing ocean acidification
The increase in the emission of the greenhouse gases is making oceans acidic. The Atmospheric CO2 get dissolved in the oceans, making them more acidic. This results in changing the chemistry of the oceans, depleting carbonate ions — the building blocks for many marine organisms.
Though the climate change is a global problem, yet we can serve as a responsible citizen to global earth by bringing small changes. We should start using Fluorescent Light Bulbs as they consume less energy. Planting more and more trees, Avoid Lighting at Day Time, use of Electric or Hybrid Car, use of clean energy, etc are few things can help in checking climate change. Last but not least is spreading awareness about Global Warming and Climate Change.
