The last ice age
A team of scientists has discovered that a giant 'burp' of carbon dioxide (CO2) from the North Pacific Ocean helped trigger the end of last ice age, around 17,000 years ago.
Globe had fourth hottest March; US cooler than normal
U.S. government forecasters calculated that for most of the Earth, last month was one of the hottest Marchs on record—except in the United States.
Study says Arctic melt season lengthening, ocean rapidly warming
The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in ...
First animals oxygenated the ocean, research suggests
The evolution of the first animals may have oxygenated the earth's oceans – contrary to the traditional view that a rise in oxygen triggered their development.
Researchers find proof of global cooling after Chicxulub asteroid impact
Dissolved iron in North Atlantic traced to sources
Iron is present in tiny concentrations in seawater. On the order of a few billionths of a gram in a liter.
April global temperature tied for highest since 1880, NOAA reports
April was historically hot across the globe, tying with 2010 for the highest average temperature since 1880, the National Oceanic and Atmospheric Administration said Tuesday.
Researchers look to the Southern Ocean for an explanation of the 'Last Glacial Maximum'
The paleoclimate record for the last ice age—a time 21,000 years ago called the "Last Glacial Maximum" (LGM)—tells of a cold Earth whose northern continents were covered by vast ice sheets. Chemical traces ...
UN weather agency warns of 'El Nino' this year
The UN weather agency Tuesday warned there was a good chance of an "El Nino" climate phenomenon in the Pacific Ocean this year, bringing droughts and heavy rainfall to the rest of the world.
New data confirms Arctic ice trends: Sea ice being lost at a rate of five days per decade
(Phys.org) —The ice-free season across the Arctic is getting longer by five days per decade, according to new research from a team including Prof Julienne Stroeve (UCL Earth Sciences). New analysis of satellite ...
Globe breaks May temperature record (Update)
Driven by exceptionally warm ocean waters, Earth smashed a record for heat in May and is likely to keep on breaking high temperature marks, U.S. experts say.
New understanding of ocean passageway could aid climate change forecasts
(Phys.org) —The passageway that links the Pacific Ocean to the Indian Ocean is acting differently because of climate change, and now its new behavior could, in turn, affect climate in both ocean basins ...
Ocean on Saturn moon could be as salty as the Dead Sea
(Phys.org) —Scientists analyzing data from NASA's Cassini mission have firm evidence the ocean inside Saturn's largest moon, Titan, might be as salty as the Earth's Dead Sea.
UCLA study yields more accurate data on thousands of years of climate change
Using a cutting-edge research technique, UCLA researchers have reconstructed the temperature history of a region that plays a major role in determining climate around the world.
