Arctic sea ice shrinks to second-lowest extent this month since satellite observations started

The National Snow and Ice Data Center has announced that Arctic sea ice witnessed its second-lowest level this month since the time satellite observations have started. The center said that the area, which used to be covered by at least 15% of the sea surface with ice, has reduced to the year’s low point of 4.14 million square kilometers on Saturday.

Very-low possibility of La Niña occurrence this fall and winter: NOAA

Very-low possibility of La Niña occurrence this fall and winter: NOAA

A NOAA report states that there very few chances that La Niña conditions will develop this fall or winter. There are 55 to 60% chance that neutral condition will be in place this fall and winter, said the NOAA. Owing to it, the agency has cancelled its La Niña watch as well.

It is not a unique phenomenon, said the researchers, as it can happen and has in the past as well. La Niña/El Niño are basically the periodic cooling and warming of the eastern and central Pacific Ocean. The last winter witnessed a strong El Niño.

New, complex model suggests Sakurajima volcano could erupt catastrophically in next 25-30 years

New, complex model suggests Sakurajima volcano could erupt catastrophically in next 25-30 years

Researchers have warned that Sakurajima volcano, a Japanese volcano, could erupt in a disaster manner in the next 25-30 years. Last time, the volcano erupted in 1914 and as per the researchers the liquid magma is growing beneath the volcano every year.

Study’s co-researcher James Hickey from the University of Exeter's Camborne School of Mines in England, said that the volcano’s reservoir is expanding at a fast pace. From the current analysis, scientists would be better positioned to predict when other big-sized volcanoes could erupt.

Three-year coral reef airborne lab mission to solve problems related to coral’s health

A project head by NASA is underway that aims to find out mysteries regarding what factors drive coral reef health. The data from the study could help experts have better information to tackle the problem efficiently.

August 2016 ties with July for warmest month ever recorded: NASA

August 2016 ties with July for warmest month ever recorded: NASA

August 2016 was the hottest August since the time record-keeping started in the 1880s, unveiled NASA in a report. As per different sources, August was 1.8 degrees Fahrenheit hotter than average August temperature from 1951 to 1980.

The study has also unveiled that the August 2016 global temperature has tied with July to bear the tag of the warmest month ever recorded. NASA said that August has been marked as the 11th continuous month in which average temperature records were broken.

Wilderness area twice the size of Alaska lost in last 20 years: Study

Wilderness area twice the size of Alaska lost in last 20 years: Study

An alarming revelation has been made in a research paper that since the 1990s around a tenth of earth’s wilderness has been lost. Human activity and disturbance have been reducing these natural spots on an annual basis and this will impact habitat of many wild species.

Scientists from the Wildlife Conservation Society have reached the conclusion after assessing satellite and survey data dating back to the 1990s. From the assessment, the researchers have come to know that across the globe, area twice the size of Alaska has been lost in the last two decades.

Climate change results into Hawaiian forest birds’ die-offs

Climate change results into Hawaiian forest birds’ die-offs

A journal Science Advances-published research paper has provided yet another evidence of how climate change is altering earth. Study researchers have found that a drop has come in the population of native forest birds on the Hawaiian island of Kauai. They also face the threat of extinction because of climate change.

The climate change is heating the birds’ habitat and allows thriving and spread of mosquito-borne diseases. Global warming increases temperature resulting into the spread of diseases like avian malaria in wooded areas.

IUCN Report details oceans condition in response to climate change

IUCN Report details oceans condition in response to climate change

Lately, International Union for Conservation of Nature (IUCN) has released a report that unveils about the condition of oceans in the wake of climate change. Increasing severity of storms, coral die-offs and death of fish clearly show that oceans have reached to its maximum limit to suffer.

China’s efforts bring back giant panda from brink of extinction

China’s efforts bring back giant panda from brink of extinction

Chinese conservation efforts have brought back giant panda from the verge of extinction. China’s national icon has been taken off from the endangered list, an effort that China has been making for past many years.

There was a time when the giant panda was present across southern and eastern China. But owing to expansion of human population and development, these bears are now only present in areas where bamboo forests are present.

Magnetite particles from air pollution detected in human brains

Magnetite particles from air pollution detected in human brains

A latest study has unveiled about the detection of toxic nanoparticles from air pollution in human brains. The detection in abundant quantities is a matter of concern as it has been suggested that there is a link between the magnetite particles and Alzheimer’s disease.

As per study researchers, air pollution has been considered to increase the risk of Alzheimer’s disease. Study’s lead researcher Prof Barbara Maher, at Lancaster University, said that their next step would be to assess these nanoparticles as an environmental risk factor for Alzheimer’s disease.
