Carbon dioxide levels breaching the 400ppm mark signifies a rising emissions problem, and the rate at which greenhouse gas emissions are rising is a matter of serious concern.
If the mangroves keep dying, shorelines will erode, sediment will become mobilised and will redeposit elsewhere. Soon the entire ecosystem would be disrupted and smaller fish won’t have a safe habitat.
A 9.0 magnitude earthquake in the Aleutians may strike in the next 50 years and it would trigger a tsunami that may destroy Hawaii completely.
After scientists discovered the extra teeth in the beaked whale, they appealed to fellow colleagues across the world, including Smithsonian Institute in the US. No one could arrive at an answer.
For the first time scientists found a way to sample the chemistry of ancient Earth's upper atmosphere. Surprisingly, the sampling indicated much higher concentrations of oxygen than expected.
New data from Swarm satellites suggest how changes in magnetic field of Earth may determine how space events such as solar storms will affect life in future.
This new study has debunked popular theories that associate full moon with depression, psychotic episodes, dog bites, car accidents and suicide.
SOFIA soars on a plane 45,000 feet above Earth. The discovery of atomic oxygen is immensely exciting as Mars is considered human’s potential new home.
As the sun was 20 percent less luminous 2.7 billion years ago, earth would have been covered in ice if it had similar atmospheric conditions prevailing now. Still, life prevailed.
In March, NASA scientist James Hansen, who is well-known for his studies on climate change, estimated that in the coming century, sea levels may rise by seven metres.
Researchers from Columbia University have suggested various measures to combat doomsday, such as uploading human minds to machines or altering earth’s orbit by launching an asteroid.
As anthropoid primates, from whom monkeys, apes and humans came, first appeared in Asia, it is important to understand their fate on the continent to find out more about human evolution.
Early earth’s oceans were bombarded by large meteors, comets and asteroids, which were responsible for planting the seeds of life that then took root after certain hydrothermal systems started operating.
Director of ARC Centres of Excellence, professor Terry Hughes, is vigorously spreading awareness on the condition of the Great Barrier Reef and criticising authorities for not taking appropriate actions.
Shark policy expert Christopher Neff wants makers of the technology to study the total ecological impact of the cable. However, he is pretty upbeat about the new shark deterrent cable.
Inside the Martian chamber, the melting ice produced liquid water that boiled energetically. It flowed down the slopes and then filtered into the sand.
The cable is harmless to humans and sharks and floats just under the ocean surface. The cable works electronically and it confuses sharks’ sensory system.
In 2013, IceCube scientists said that they had detected two neutrinos coming from outside our galaxy and unimaginably energetic. Now, the source of such extragalactic neutrinos may have been revealed.
To verify their results, the scientists compared the 2-billion years old crystals to crystals that are much more ancient (more than 4 billion years old). The hypothesis proved right.
More than 12 percent of Greenland’s ice sheets have melted, which is alarming. The cause of this has been attributed to warm air passing through Greenland from south-west.
The researchers are of the opinion that tailless Manx formed in the same region as earth, unlike most comets, that formed in the far icy reaches of the solar system.
The scientists warned that if greenhouse gases keep rising, then by mid-2030s, the reef will start experiencing deadly coral bleaching events like the current one every two years.
Humans generally experience four or five long slow-wave/REM sleep cycles every night. Shockingly, the Australian bearded dragons showed 350 80-second-long cycles, scientists said.
Hitomi was launched in February and was met with widespread support and jubilation. However, a month later, ground control engineers lost all contact with the JAXA satellite.
Oxygen levels in the seas are falling at an alarming rate and widespread evidence of the trend will be evident 2030 onward. Climate change makes oceans turn over less.
Greens have revealed their plans of taxing coal and using proceeds in the conservation of Australia’s Great Barrier Reef after it goes under threat of destruction from coral bleaching.
While the greening of Earth seems like a positive sign for many, Canadell expressed grave concerns as such exponential increase in CO2 levels would mean severe weather and rising sea levels.
Scientists, in a bid to find evidence of supernovae in cosmic rays travelling through space, analysed NASA's Advanced Composition Explorer (ACE) spacecraft’s data.
The discovery of the new reef system in the mouth of the Amazon River is capable of providing scientists a broader view of the reef community, its variations and changes.
Professor Joshua Madin said this is the worst case of bleaching ever in Sydney Harbour and the event is an indicator of devastating environmental disasters that are going to hit our planet.
