NASA study solves case of Earth’s ‘missing energy’

This item was filled under [ Climate ]
Two years ago, scientists released a study claiming that inconsistencies between satellite observations of Earth's heat and measurements of ocean heating amounted to evidence of "missing energy" in the planet's system. Where was it going? Or, they wondered, was something wrong with the way researchers tracked energy as it was absorbed from the sun and emitted back into space? An international team of atmospheric scientists and oceanographers set out to investigate the mystery....

What really happened prior to ‘Snowball Earth’?

This item was filled under [ Climate ]
The large changes in the carbon isotopic composition of carbonates which occurred prior to the major climatic event more than 500 million years ago, known as "Snowball Earth," are unrelated to worldwide glacial events, a new study suggests....

NASA infrared satellite instrument sees tropical storm Iggy growing in strength

This item was filled under [ Climate ]
The AIRS infrared instrument that flies on NASA's Aqua satellite has been providing forecasters with the cloud top temperatures in the Southern Indian Ocean's ninth tropical cyclone, which has officially been renamed Iggy. AIRS data showed that the area of strong thunderstorms around Iggy's center has expanded in area over the last day....

Ecologists capture first deep-sea fish noises

This item was filled under [ Climate ]
Fish biologists conducted one of the first studies of deep-sea fish sounds in more than 50 years, 2,237 feet under the Atlantic. With recording technology more affordable, fish sounds can be studied to test the idea that fish communicate with sound, especially those in the dark of the deep ocean....

Injecting sulfate particles into stratosphere won’t fully offset climate change

This item was filled under [ Climate ]
New research demonstrates that one suggested method of geoengineering the atmosphere to deal with climate change, injecting sulfate particles into the stratosphere, probably would have limited success....

Underwater river of mud and sand tells tale of climate change and ocean gateways, new oil and gas exploration possibilities

This item was filled under [ Climate ]
Mediterranean bottom currents and the sediment deposits they leave behind offer new insights into global climate change, the opening and closing of ocean circulation gateways and locations where hydrocarbon deposits may lie buried under the sea. A team of 35 scientists from 14 countries recently returned from an expedition off the southwest coast of Iberia and the nearby Gulf of Cadiz. There the geologists collected core samples of sediments that contain a detailed record of the Mediterranean's history. The scientists retrieved the samples by drilling into the ocean floor during an eight-week scientific expedition onboard the ship JOIDES Resolution....

Life discovered on dead hydrothermal vents

This item was filled under [ Climate ]
Microbiologists have found that the microbes that thrive on hot fluid methane and sulfur spewed by active hydrothermal vents are supplanted, once the vents go cold, by microbes that feed on the solid iron and sulfur that make up the vents themselves....

Marine mammals on the menu in many parts of world

This item was filled under [ Climate ]
The fate of the world's great whale species commands global attention as a result of heated debate between pro and anti-whaling advocates, but the fate of smaller marine mammals is less understood, specifically because the deliberate and accidental catching and killing of dolphins, porpoises, manatees, and other warm-blooded aquatic species are rarely studied or monitored....

Major study of ocean acidification helps scientists evaluate effects of atmospheric carbon dioxide on marine life

This item was filled under [ Climate ]
Might a penguin's next meal be affected by the exhaust from your tailpipe? The answer may be yes, when you add your exhaust fumes to the total amount of carbon dioxide lofted into the atmosphere by humans since the industrial revolution. One-third of that carbon dioxide is absorbed by the world's oceans, making them more acidic and affecting marine life....
