DEBUNKING THE MYTHS ABOUT CLIMATE CHANGE

As the saying goes, “there is no worse blind man than the one that doesn’t want to see”, this proverb is analogous to the people who still are adamant to their stance that “Climate Change is a hoax”. And this isn’t just the normal people, it’s even some political leaders and some famous presidents who strongly reprimand the concept of climate change. So, how do these people justify their stances? Believe it or not, there are many claims made by people which have no scientific basis whatsoever. Therefore, debunking these myths is paramount.

  1. Global Warming isn’t real as it’s still cold

This is the most common and misunderstood claim. So, what is the science behind it? The science behind it is that, the Earth is warming actually means that the average temperature of the Earth surface is increasing which means that there could be periods of extreme heat as well as extreme cold. However, the overall temperature is increasing overall. This is not only making heatwaves and droughts more likely but it’s also causing changes to our natural climate systems. For example, hurricanes and storms are becoming more intense, moving slower and taking longer to die down. The heatwaves in countries of Africa and India have been more extreme.

2. If Planet is getting hotter then how come Antarctica’s ice is increasing?

So, is that true? Well, that’s what happens when people confuse sea ice with land ice. The Antarctica is a land mass covered with ice sheet and is surrounded by sea water which has ice on its surface.

Sea ice is ice that spreads over the surface of Antarctic ocean. And here’s what you need to know. The claim that Antarctic ice is increasing is actually indicating that the sea ice cover over the Antarctic is increasing, which barely has any effect on the global sea level rise. It has no effect in that the sea ice only gets spread farther apart in area due to the westerly winds and ice does not increase in volume. That’s right, No volume increase and hence this causes no sea level rise.

However, the sea level is increasing because the land ice is increasingly melting. Due to the increase in warming, the warm oceans encroach the land base, also known as bed rock, where the huge masses of ices rest. The replacement of this bed rock by water means that more chunk of ice and glaciers gets released to the water thereby accelerating sea level rise.

And how has this affected us? Between 1992 and 2017, Antarctica lost more than 3 trillion tonnes of ice. And this made the global sea levels rise by about 7.6 mm.

3.  THE EARTH’S CLIMATE HAS ALWAYS CHANGED  

If you’ve heard someone claim this, you must’ve found them unable to back their claim by evidence. It is true that over the course of 4.5 billion years since Earth’s existence, the climate has changed to a great degree. However, the exorbitant warming at present does not follow the normal cycles of cooling and warming and these changes which normally would occur over a period of 100 years, are occurring over decades and in higher intensity. To back this by statistics, 17 of the 18 warmest years on record have all taken place since 2001.  

So, how is this warming any different?

The rapid warming is actually direct cause of higher concentration of carbon dioxide in the atmosphere which have been emitted by human activities

4. Increasing the average temperature by a couple of degrees is not harmful

To humans who experience variation in temperature of few degrees in their every day, it must seem normal to think that the average increase in few degrees doesn’t cause major catastrophes. However, what seems like a minimal difference for us, is devastating for agriculture, flora, oceans, and species of insects and animals whose survival is tightly linked to climatic conditions. In fact, an important percentage of planetary biodiversity is already suffering from it.

Furthermore, the increase in average temperature by just few degrees has introduced more severe floods, extreme droughts, death-inviting heat waves, and longer and more extreme hurricanes. This already experienced catastrophes which have displaces and threatened many human lives with just a mere increase in few degrees if temperature gives us a reality check as to the gravity of this situation.

When an individual doesn’t understand the causes, effects and the science of climate change, it is understandable for people to be swayed by their view point. Therefore, it is important to include climate science in school level curriculum in order to educate people about the gravity of the situation. Only then can we encourage people to take action to combat climate change.
