New study indicates Earth's inner core was formed 1-1.5 billion years ago

There have been many estimates for when the earth's inner core was formed, but scientists from the University of Liverpool have used new data which indicates that the Earth's inner...

Volcanic eruptions affect flow of world's major rivers, study finds

Major volcanic eruptions can have a significant effect on the flow of the biggest rivers around the world, research shows.

Signs of ancient megatsunami could portend modern hazard

Geologists think that the eastern slope of Fogo volcano crashed into the sea some 65,000 to 124,000 years ago, leaving a giant scar where a new volcano can be seen growing in this satellite image.Scientists working off west Africa in the Cape Verde Islands have found evidence that the sudden collapse of a volcano there tens of thousands of years ago generated an ocean...

King crabs threaten Antarctic ecosystem due to warming ocean

If climate change allows shell-crushing predators such as king crabs to return to the Antarctic continental shelf, the crabs will likely disrupt the endemic marine fauna.King crabs may soon become high-level predators in Antarctic marine ecosystems where they haven't played a role in tens of millions of years, according to a new study led by...

Icelandic volcano's toxic gas is treble that of Europe's industry

Plumes of smoke and flames rise from an eruption at Bárðarbunga volcano, Iceland, in 2014. The amount of sulphur dioxide emitted in the six-month eruption was treble that given off by all of Europe's industry.A huge volcanic eruption in Iceland emitted on average three times as much of a toxic gas as all European industry combined, a study has revealed.

Connecting the dots: Integrated biodiversity data could be the key to a sustainable future

This figure illustrates how biodiversity data can be mobilised by Biodiversity
Observation Networks (BONs), such as the European Biodiversity Observation Network (EU BON), for use in policy implementation.Biodiversity Observation Networks (BONs) have recently become a hot topic on the scene of natural sciences. But what is their role in advancing our knowledge of biodiversity and associated...

Study: Fukushima disaster was preventable

The worst nuclear disaster since the 1986 Chernobyl meltdown never should have happened, according to a new study.

Arctic mosquitoes thriving under climate change, Dartmouth study finds

Lauren Culler, a postdoctoral researcher at Dartmouth's Dickey Center's Institute of Arctic Studies, and her colleagues find that warming temperatures are causing Arctic mosquitoes to grow faster and emerge earlier, significantly boosting their population and threatening the caribou they feast on.Warming temperatures are causing Arctic mosquitoes to grow faster and emerge earlier, significantly boosting their population and threatening the caribou they feast on, a Dartmouth College study finds.

Sweeping study of US farm data shows loss of crop diversity the past 34 years

U.S. farmers are growing fewer types of crops than they were 34 years ago, which could have implications for how farms fare as changes to the climate evolve, according to...

Sierra Nevada snowpack lowest in five centuries

These two natural-color satellite images of the snow cover in the Sierra Nevada in California and Nevada show the last year with average winter snowfall, 2010, compared with 2015 -- a year that had the lowest snowpack in 500 years. The images were taken by the Moderate Resolution Imaging Spectroradiometer on NASA's Aqua satellite.Snowpack in California's Sierra Nevada in 2015 was at the lowest level in the past 500 years, according to a new report led by University of Arizona researchers.

Wet paleoclimate of Mars revealed by ancient lakes at Gale Crater

A view from the Kimberley formation looking south. The strata in the foreground dip towards the base of Mount Sharp, indicating the ancient depression that existed before the larger bulk of the mountain formed.We have heard the Mars exploration mantra for more than a decade: follow the water. In a new paper published October 9, 2015, in the journal Science, the Mars Science...

Ancient rocks record first evidence for photosynthesis that made oxygen

Aaron Satkoski, a scientist in the UW-Madison Geoscience Department, holds a sample sawn from a 3.23-billion-year-old rock core sample found in South Africa. The bands show different types of sediment falling to the ocean floor and solidifying into rock. The sample provides the earliest known evidence for oxygenic photosynthesis.A new study shows that iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen. The only logical source for that oxygen is...

A simpler way to estimate the feedback between permafrost carbon and climate

The new approach includes data from recently compiled soil carbon maps of permafrost in Alaska, Canada, and Russia.One of the big unknowns in predicting climate change is the billions of tons of carbon frozen in Arctic permafrost. As global warming causes soil temperatures to increase, some of...

Goods manufactured in China not good for the environment, study finds

In a study published today in the journal Nature Climate Change, scientists from three universities show that products made in China are associated with significantly higher carbon dioxide emissions than...

Offshore wind farms could be more risky for gannets than previously thought, study shows

Offshore wind farms which are to be built in waters around the UK could pose a greater threat to protected populations of gannets than previously thought, according to a new...

UGA study ranks US cities based on the urban heat island effect on temperatures

This graphic shows the annual average urban heat island effect in 2010.Inner cities as well as suburbs show distinctly warmer temperatures--known as the urban heat island effect--than rural areas as a result of land use and human activities, which can affect...

Arctic sea ice summertime minimum is fourth lowest on record

The 2015 Arctic sea ice summertime minimum is 699,000 square miles below the 1981-2010 average, shown here as a gold line.According to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began.

World's longest continental volcano chain in Australia: ANU media release

The Cosgrove volcano track is shown.Scientists have discovered the world's longest known chain of continental volcanoes, running 2,000 kilometres across Australia, from the Whitsundays in North Queensland to near Melbourne in central Victoria.

Burning remaining fossil fuel could cause 60-meter sea level rise
