Autonomous Buoy Helps Study Optical Properties and Thickness of Diminishing Arctic Sea Ice

Arctic sea ice has diminished significantly in recent decades, particularly in summer. Researchers from Norway and China have collaborated on developing an autonomous buoy with instruments that can more precisely measure the optical properties of Arctic sea ice while also taking measurements of ice thickness and temperature.

Ocean Acidification Might Alter Climate-Relevant Functions of Oceans’ Uppermost Layer

Ocean acidification might alter climate-relevant functions of the oceans’ uppermost layer, according to a study by a group of marine scientists published in the “Journal of Geophysical Research: Oceans”.

Researchers Develop New Climate Change Modeling Tool

A new climate change modeling tool developed by scientists at Indiana University, Princeton University and the National Oceanographic and Atmospheric Administration finds that carbon dioxide removal from the atmosphere owing to greater plant growth from rising CO2 levels will be partially offset by changes in the activity of soil microbes that derive their energy from plant root growth.

Study Results Help Understand What Happens to the Planet Under Climate Change

While computer models churn out bleak forecasts for the planet’s future, we also have a more conceptual understanding of what is happening as humans pump carbon dioxide into the air. But the conceptual understanding of carbon dioxide wrapping the planet in a blanket that traps more heat is not quite right.

Research Reveals Recent Increase in Ozone-Depleting Atmospheric Hydrogen Chloride

Research from the University of Leeds and an international team of scientists has shown a recent increase in atmospheric hydrogen chloride (HCI), a substance linked to destruction of the ozone layer.

Altered Atmospheric Circulation Due to Changing Ice Sheet Height also Influences Climate Change in Heinrich Events

In a study published today in PNAS, Dr William Roberts of Bristol's School of Geographical Sciences and colleagues use computer models to simulate a Heinrich event in Hudson Bay, Canada, adjusting the models to consider freshwater influx only, changing ice sheet height only or both factors together.

Neglecting Linkages Between SLCFs and CO2 Overestimates Long-Term Climate Benefits

Targeting emissions of non-CO2 gases and air pollutants with climate effects might produce smaller benefits for long-term climate change than previously estimated, according to a new integrated study of the potential of air pollution and carbon dioxide mitigation.

Reduction in Carbon Dioxide Emissions Definitely Needed to Address Global Warming

When fossil fuels are burned, other climate-forcing gases are produced in addition to long-lasting carbon dioxide. Diesel combustion in vehicles or coal in power plants creates soot particles, which also contribute to global warming, albeit only briefly as they disappear quickly from the atmosphere.
