Climate change issue: Nights getting warmer faster than days
There was a time when there was no need of air conditioner during the nights. But global warming and climate change has made these things compulsory in our lives today.

Climate pattern change is bringing more extreme and unpredictable weather across the world. Due to climate change the planet has warmed up by an average of nearly 1°C in the past century. According to a new study, it's been examined that night time temperatures are more sensitive to climate change, so nights have been warming much faster than the days. 

Researchers analyzed the cause of these changes by observations and model reconstructions of the climate in the 20th century. They saw that part of this more rapid warming at night is natural to the climatic system, because during nights the temperatures are inherently more sensitive to climate forcing.

The layer of air just above the ground is known as the boundary-layer, and it is essentially separated from the rest of the atmosphere. At night-time the layer is exceptionally thin, just a few 100 meters, whereas during the day-time it grows up to a few kilometers. And this is the basic reason why the temperatures during nights are more sensitive to warming than the day. 

This daily cycle in temperature directly affects human health, as it can trigger temperature-related fatalities. However, it also indirectly affects the human health by controlling the growth rates of vegetation, and hence affecting the length and stability of crop-growing seasons.
