Scientists point at dust accumulating in the atmosphere for increasingly taking toll on the ecological balance. Mountainous regions and snow clad peaks are noted to have been camouflaged in reddish brown tinge of dust- a canopy on the impeccable white.
As an effect of global warming, droughts have intensified and have become a potential reason for dust flow. It has been reported that in a span of 3 years the layer of dust canopy has multiplied at least 5 times.
This has lead to a weird scenario. Dark and dusty snow surface invariably absorbs way more solar energy than reflective white surfaces. This leads to fast warming up of the snow, leading to a melt-down.
Owing to an early disappearance and expansion of the blooming season, plants consume comparatively more water and transpire it. That same quantity of water would have flowed into the river stream that is lost as vapor. Decrease in the net amount of water inflow results in a significant deficit in the availability of fresh river water.
Besides drop in the level of water inflow in rivers, untimely melting of snow also bares the ground, exposing it to absorb more heat, thus warming the atmosphere. This definitely is among the potential effects of global warming.
Researchers claim that our civilization is completely overlooking a very important aspect of climate change i.e. dust. The fundamental alterations as well as the dynamism with which it has been impacting climate change have not been paid heed to. As a consequence, human beings have recklessly continued their developmental activities and farming. Proceeding further towards the arid belts has destroyed vegetation, exposing soil to wind erosion. This dust in turn leads not only to rapid meltdowns and adequate water-flow in rivers, but also directs the dust borne pathogens to affect human health significantly.
The scientific community believes, dust connect ecosystems worldwide. Dust enriched with nutrients scarce in supply, like phosphorus, nitrogen, iron, carbon and micronutrients often help in regulating the distribution of life on earth.
On the contrary, there has been a rise in the cases of Valley fever- a fungus that resides in desert areas and mingles with dust to flow across. A rare illness referred to as Kawasaki disease caused due to bacteria and virus that travels during yellow dust storm, inflates blood vessels. Meningitis is another commonly heard disease caused by bacteria carried by dust.
Scientists are calling upon the intelligentsia to quantify the adverse impact dust has on human health factor as well as environmental sustainability. The role that it has been playing in altering the earth’s ecosystem has so far been neglected, but, demands immediate attention in order to restore balance on an urgent basis to save further loss of biodiversity.
