An Interesting Scientific Revelation on How Dust Leads to Global Warming

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.

Blame it on Global Warming for Kelp Forests Declining across the Globe

Dense growth of giant plant-like brown algae, known as kelp, found in shallow waters around the Marine Forests of South East Australia is progressively losing its ground to sea urchins. This sudden shift is devastating the balance of the underwater ecology, creating urchin barrens- bereft of life and vegetation. Consequentially, peripheral species that form an integral part of the food web are continually pushing off to the brink of extinction.

Scientists blame it on the effects of global warming that is increasingly devouring the Australian coastal ecosystem and destroying the biodiversity.  38 % of Kelp forests owe their destruction to rising ocean temperatures and warm seas which seems to have surpassed 3 degree Fahrenheit. Tropical species are making its way in, altering conventional marine habitats as in Tasmania and parts of Australia.

The tropicalisation phenomenon has engulfed the ecology in a way that cold water organisms are being increasingly replaced by tropical organisms. Often, these intrusive elements devour on the kelp, discouraging the growth.

The rapid shoot up in temperatures of the Atlantic ocean in western Europe has lead to the growth of turf algae, wiping off kelp in France, Denmark, Norway and southern England. In parts of the US expansive kelp forests running miles along the coastline fell victim to a massive die down. Thus, we see the effects of global warming have spread its tentacles to check kelp growths across the globe.

Besides ocean heat waves, pollution from waste water are among the plausible factors that has impacted the kelp forests leaving litters in the sub surface.

Researchers are bent upon active restoration efforts to recover and conserve kelp forests from further damage. Active restorative procedures have fetched considerable results in the past. For an instance, return of craywood forests in Australia, creating marine reserves that prohibits fishing and stops warm water variants to flock in cooler areas has yielded significant results.

Both- local as well as global causes leading to the decline need to be immediately checked in order to maintain the ecological balance. This refers to preventive mechanisms at the human end like reducing green house emissions and work towards taming pollution.

How Far the Recent Developments Can Mitigate Environmental Damage in 2018

Three months have already gone by now and we are still perplexed with the question on whether the devastating environmental aftermaths of global warming are about to worsen further or reduce to a considerable extent because of the implementation of result-driven initiatives.

Plastic Content in Oceans is About to Get Tripled by the Next Decade

The future of our oceans is certainly at stake and with it, the existence of millions of aquatic species is also questioned. Considering the issues of coral bleaching, rise in sea level due to climate change and plastic pollution, the oceans and life in it is being alarmingly threatened.
