Melting icebergs key to sequence of an ice age, scientists find
Scientists claim to have found the ‘missing link’ in the process that leads to an ice age on Earth.
To predict the future of polar ice, environmental scientists are looking to the past
Over the past century, global sea level has been rising at an increasingly rapid pace.
Ice sheet uncertainties could mean sea level will rise more than predicted
Sea level could rise higher than current estimates by 2100 if climate change is unchallenged, according to a new assessment.
A massive iceberg could impact island ecosystems in the southern Atlantic
A research team is planning a mission to study the potential impact of a floating iceberg as it approaches the South Georgia Island, a British overseas territory in the southern Atlantic, reports Phys.org.
Ice sheets on the move: Evidence of the interconnectedness of global climate
Analysis finds melting ice sheet affects a second thousands of miles away.
UN-Water adds Water Environment Federation as partner
The Water Environment Federation (WEF) is now an official partner of UN-Water, which coordinates the efforts of United Nations (UN) entities and international organizations working on water and sanitation issues.
Partnership between US-Qatar aims to find buried water in Earth’s deserts
Researchers will design a mission to learn about underground aquifers in areas such as the Sahara and how climate change will affect them in the future.
New freshwater database tells water quality story for 12K lakes globally
Although less than one per cent of all water in the world is freshwater, it is what we drink and use for agriculture.
Ice sheet melt on track with ‘worst-case climate scenario’
A recent report confirms that ice sheets in Greenland and Antarctica, whose mass-loss rates have been rapidly increasing, are matching the Intergovernmental Panel on Climate Change's worst-case sea-level rise scenarios.
Satellite record gives unprecedented view of Antarctic ice shelf melt pattern over 25 years
New estimates of ice shelf melting around Antarctica since the 1990s show where and when ice has been lost and where meltwater entered the Southern Ocean.
Treading on shrinking ice
Geophysicist Marco Tedesco has an affinity for ice in all its forms–snow, glaciers, ice sheets, sea ice–and has spent his career exploring its qualities and fates.
How ice scouring in the Antarctic disrupts ecosystems
Along the Antarctic coast, icebergs regularly break away from glaciers and plunge into the nutrient-rich waters below.
Early Mars was covered in ice sheets, not flowing rivers
A large number of the valley networks scarring Mars’s surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience.
Cloud data a silver lining for climate change predictions
Clouds above the Southern Ocean could hold the key to more accurate global climate change predictions.
Ice melt linked to accelerated regional freshwater depletion
Seven of the regions that dominate global ice mass losses are melting at an accelerated rate, a new study shows, and the quickened melt rate is depleting freshwater resources that millions of people depend on.
Rivers help lock carbon from fires into oceans for thousands of years
The extent to which rivers transport burned carbon to oceans – where it can be stored for tens of millennia – is revealed in new research led by the University of East Anglia (UEA).
CO2 emissions from dry inland waters globally underestimated
Study fills the gap between regional and global data.
Study helps improve accuracy of future climate change predictions
New research published by NUI Galway’s Centre for Climate & Air Pollution Studies (C-CAPS) has shone light on the impact of clouds on climate change.
World Meteorological Day focuses on climate and water
One of the biggest impacts of climate change is on water, which in turn affects sustainable development and security.
Greenland lost 600 billion tons of ice last summer
UCI, NASA JPL project tracking Earth-sensing satellite turnover yields striking results.
