Release of ancient methane due to changing climate kept in check by ocean waters

Wed, 17 Jan 2018 16:40:22 EST ~ Ocean sediments are a massive storehouse for the potent greenhouse gas methane. But methane only acts as a greenhouse gas if and when it reaches the atmosphere. Environmental scientists recently set out to discover whether or not this ancient-sourced methane, which is released due to warming ocean waters, survives the journey from the seafloor and reaches the atmosphere.

Researchers explore psychological effects of climate change

Wed, 17 Jan 2018 16:40:10 EST ~ While some people have little anxiety about the Earth's changing climate, others are experiencing high levels of stress, and even depression, based on their perception of the threat of global climate change, researchers found. Psychological responses to climate change seem to vary based on what type of concern people show for the environment, with those highly concerned about the planet's animals and plants experiencing the most stress.

Future climate change revealed by current climate variations

Wed, 17 Jan 2018 13:11:32 EST ~ Uncertainty surrounding the extent of future climate change could be dramatically reduced by studying year-on-year global temperature fluctuations, new research has shown. Find out more...

Coping with climate stress in Antarctica

Wed, 17 Jan 2018 12:16:40 EST ~ Some Antarctic fish living in the planet's coldest waters are able to cope with the stress of rising carbon dioxide levels the ocean. They can even tolerate slightly warmer waters. But they can't deal with both climate change stressors at the same time, according to a new study. Find out more...

Weather anomalies accelerate the melting of sea ice

Tue, 16 Jan 2018 22:25:26 EST ~ Researchers reveal why Arctic sea ice began to melt in the middle of winter two years ago -- and that the increased melting of ice in summer is linked to recurring periods of fair weather. Find out more...

Scientists home in on a potential Anthropocene 'Golden Spike'

Tue, 16 Jan 2018 13:13:22 EST ~ Scientists are reviewing the potential settings where a global reference section for the Anthropocene might be searched. Find out more...

Scientists home in on a potential Anthropocene 'Golden Spike'

Mon, 15 Jan 2018 09:51:58 EST ~ A new study suggests that key geological markers align towards a start for the Anthropocene somewhere between 1952 to 1955, based on signals from nuclear testing and fossil fuel burning. Find out more...

Robots aid better understanding of phytoplankton blooms

Mon, 15 Jan 2018 09:42:31 EST ~ Phytoplankton blooms are one of the most important factors contributing to the efficiency of the carbon pump in the North Atlantic Ocean. To better understand this phenomenon, researchers have developed a new class of robots able to collect data in the ocean throughout the year. Using these unparalleled data, the researchers have identified the starting point for the explosive spring phytoplankton bloom. Find out more...

Sanchi oil spill contamination could take three months to reach mainland

Sat, 13 Jan 2018 09:37:33 EST ~ Water contaminated by the oil currently leaking into the ocean from the Sanchi tanker collision is likely to take at least three months to reach land, and if it does the Korean coast is the most likely location. However, the oil's fate is highly uncertain, as it may burn, evaporate, or mix into the surface ocean and contaminate the environment for an extended duration. Find out more...

Thinking outside the box on climate mitigation

Fri, 12 Jan 2018 10:51:10 EST ~ A new article lays the groundwork for alternative climate mitigation scenarios that place less reliance on unproven negative emissions technologies in the future. Find out more...
