The increasing chills
“I shrugged and shivered. My feet and hand were cold as ice. I thought I was going to have a fever. I rushed to take a blanket when I saw my brother doing the same. I asked if he felt it too and I got to know it was not the fever that made me feel so it was the sign, winter is here.
From the past years if we look at the temperature readings of October in Kathmandu we can see the increase in the range of highest and lowest temperature of a day. The diurnal courses are warmer while the nights and mornings are bleaker.
Now this puts us into a dilemma and gets us thinking “If the surface is getting warmer why is it getting chillier?” The answer to it is still Global Warming. We have become familiar with the term Global Warming over the past decades. It is in fact one of the major issues of the world.
Global Warming basically is a century-scale of rising global temperatures caused by the heat that is trapped inside the Earth’s surface by greenhouse gases. It is not a one year or a decade long phenomena but a century long process which means we cannot dive to conclusions on climate change based on minimal observations.
Studies from NASA and as discussed in Earth Talks, Global Warming as a whole does increase the surface temperature and is also responsible for extreme weather conditions. These include, heavy snowfall, snowstorms to droughts and hurricanes. Recently, we have seen major hurricanes hitting the coastal areas of Caribbean countries, Florida and Texas. We can also see how the Arctic sea ice has shrunk to its eight lowest according to observations of September 13. Due to the increased precipitation, the Terai region of Nepal was flooded this monsoon.
The Earth is going to change its climate patterns as shown by Cambridge University studies. The tropics will be having droughts and the poles will be having high precipitations, besides some exceptions. Well this is because with the increasing temperature, evaporation increases bringing more rain in the areas where there are water sources. Global Warming causes the ice caps to melt leading to rise in sea levels which means that the poles and higher altitudes are more likely to have ample water sources.
We can say that Kathmandu may experience harsh chills with the extreme effects of Global Warming. But, let’s become more aware this winter to address the increasing chills with green energy sources to keep us warm.
