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.

Warming seas intensifying Asian typhoons

Warming seas intensifying Asian typhoons

Researchers have found that global warming is increasing the temperature of seas resulting into rise in the destructive power of typhoons across Philippines, Japan, China, and Korea by about 50% in the past 40 years.

Alaska can be seen like never before in new most accurate digital elevation maps

Alaska can be seen like never before in new most accurate digital elevation maps

Alaska is among the most poorly mapped places on the planet. In reality, until now the topographic maps of the Red Planet and the moon were typically more detailed in comparison to those of the Arctic state. The White House, National Science Foundation and National Geospatial Intelligence Agency (NGA) have this week shared the most precise digital elevation maps of Alaska ever made.

Arctic sea ice melting at alarming rates is a new normal

Arctic sea ice melting at alarming rates is a new normal

Melting of the Arctic sea ice, which started at an alarming pace and then the melt slowed down by June, has now led NASA scientists to affirm that they should consider this kind of melt as the new normal.

Walt Meier, a sea ice specialist at NASA’s Goddard Space Flight Center, was of the view that if this incident would have taken place a decade back then it would have surely set a new record low. But now, Meier said that they are quite used to these low levels of sea ice, in fact a new normal.

Free-to-use interactive game to communicate climate change impact on Antarctic Ice Sheet

Free-to-use interactive game to communicate climate change impact on Antarctic Ice Sheet

A new and interesting way has been found to pass on the impact of climate change on the Antarctic Ice Sheet. For it, scientists and game developers have joined hands to produce a free-to-use interactive game ‘Ice Flows’ to demonstrate how the Antarctic Ice Sheet reacts to climate change.

Through this manner, people of all age groups across the world will come to know about the impact of a changing climate on the world’s ice sheets. The game will be launched on 23 August at the SCAR (Scientific Committee for Antarctic Research) Open Science Conference in Kuala Lumpur.

Adonis: Pine tree aged at least 1,075 years old is oldest in Europe

Adonis: Pine tree aged at least 1,075 years old is oldest in Europe

A pine tree in Greece considered to be at least 1,075 years old has been termed as the oldest tree in Europe. The pine tree nicknamed ‘Adonis’ is a Bosnian pine growing in the highlands of northern Greece. It is quite unique because it does not rely on a mother plant or the ability to split or clone itself, to survive.

There are many trees in Europe that are much older like some of them have lived for nearly 10,000 years. But there is a difference and that is those trees are clonal meaning that they reproduce asexually time and again throughout history.
