Research team offers explanation for expansion of sea ice in sea ice in Antarctic region

Research team offers explanation for expansion of sea ice in sea ice in Antarctic region

A new study has shed light on as to why the sea ice in Antarctica is expanding, getting thick and spreading every year in a continuously warming world. Climate scientists from Australia and the United States said that the expansion in recent years has been majorly driven by natural climate fluctuations, particularly in sea surface temperatures.

Alaska’s Pavlof Volcano may erupt by this year’s end

Alaska’s Pavlof Volcano may erupt by this year’s end

There is a possibility that the Mount Pavlof in Alaska could erupt for the third time this year by the end of 2016. Alaska Volcano Observatory (AVO) has based its predictions on the basis of increasing seismic activity and steam emissions from the volcano.

Owing to the release of a steady plume of steam from the mountain, state authorities have raised the alert level for the area from normal to advisory status, also known as yellow alert. The officials said that the level of seismic activity at Pavlof Volcano is elevated but is lower than recorded last day.

Antarctic ozone hole in quick healing mode: Research

Antarctica ozone hole in quick healing mode: Research

A team of researchers in its paper published in the journal Science has unveiled that the Antarctic ozone hole has started to heal. It is indeed good news as around a 30 year old environmental problem is getting solved.

Study’s lead researcher Susan Solomon, MIT atmospheric scientist, said that firstly, the problem was quite worse and then it started to become stabilized and finally, the ‘ozone hole’ is healing. Solomon mentioned that the earth’s ozone layer is recovering owing to the choices and polices being made by us.

Warming climate could pose threat to Adélie penguins’ colonies in Antarctica

Warming climate may pose threat to Adélie penguins’ colonies in Antarctica

Adélie penguins have survived in Antarctica for almost 45,000 years. In this time period, the species has witnessed many changes and bravely survived them. Now, a new study has raised concerns that things may change, as 21st century climate may affect the penguin colonies of the Antarctic continent.

The research paper from the University of Delaware published in the Scientific Reports has unveiled that up to 60% of the current population of the Adélie penguins in Antarctica would not be able to host their colonies by the end of the century.

Meteorite having opal studded found in Antarctica does not belong to earth

Meteorite having opal studded found in Antarctica does not belong to earth

A latest study has unveiled about the discovery of meteorite studded with pieces of opal in Antarctica. It is suspected that the opal-studded space rock does not belong to earth. The discovery could shed light on as to how water formed on earth.

'Watermelon Snow' is playing notable role in climate change

'Watermelon Snow' is playing notable role in climate change

In summers, everybody wants to eat a big chunk of watermelon. But there’s another kind of watermelon, which can be experienced only outside. It is known as ‘watermelon snow’, and as per researchers better understanding of it can be significant in a warming world.

Worldwide, in snowy places, formation of ‘watermelon snow’ takes place when summer sun heats up, melting the leftovers of winter. The colorful snow is composed of communities of algae, flourishing in freezing temperatures and liquid water, leading to algal blooms.

Red snow algae can accelerate melting of Arctic glaciers

Red snow algae can accelerate melting of Arctic glaciers

In a new study, researchers have described about red-pigmented, snow-dwelling algae that has turned Arctic glaciers’ snow into pink. After analyzing red snow algae present across 21 glaciers in the pan-European Arctic, the researchers have raised concerns as snow algae accelerates the melting of Arctic glaciers.

Deadly combination of human presence and climate warming brought extinction of megafauna

Deadly combination of human presence and climate warming brought extinction of megafauna

A Science Advances-published research paper has unveiled that the deadly combination of the arrival of humans in Patagonia and changing climate brought the extinction of many species of megafauna around 12,000 years back in the area, which is now known as South America.

Researchers from the University of Adelaide in Australia along with scientists from South America and other places have come to know that presence of humans in Patagonia cannot alone lead to extinction. As per them, humans and a warmer climate could lead to the collapse of many species.

A first in four million years: Antarctica crosses symbolic CO2 levels

A first in four million years: Antarctica crosses symbolic CO2 levels

The National Oceanic and Atmospheric Administration (NOAA) has announced that carbon dioxide levels has crossed the symbolic mark of 400 parts per million. It has happened for the first in the four million years.

The US government agency responsible for keeping a tab on conditions of the oceans and atmosphere said that the levels would not return to values below 400ppm for many centuries.

A First: 2015-2016 El Niño pushing Atmospheric CO2 Levels above 400 ppm

Scientists say El Niño of 2015-2016 has passed, but it impacted the planet very badly. For the first time, levels of atmospheric carbon dioxide have reached 400 parts per million (ppm) for a year.

Since 1958, the Mauna Loa Climate Observatory in Hawaii has been observing concentration of carbon dioxide humans are releasing in the earth’s atmosphere. It has found that Mauna Loa’s CO2 concentration rose and fell annually in last about six decades. Due to increased human activities, carbon levels have been rising by about 2.1 ppm every year.
