NOAA's GOES-East Satellite Reveals Colder Temperatures in Cloud Tops

Some of the coldest air of the 2014-2015 winter season was settling over the eastern two-thirds of the U.S. on February 13, 2015. That Arctic air mass brought wind chills from below zero to the single numbers from the Midwest to the Mid-Atlantic. Despite the cold on the surface, infrared NASA satellite imagery revealed even colder temperatures in cloud tops associated with the air mass.

New Study Offers Roadmap for Developing Ocean-Scale Solutions to Address Plastic Marine Pollution

Ocean currents have been carrying floating debris into all five of the world's major oceanic gyres for decades. The rotating currents of these so-called "garbage patches" create vortexes of trash, much of it plastic. However, exactly how much plastic is making its way into the world's oceans and from where it originates has been a mystery -- until now.

High Seas Should be Closed to Fishing Globally

SFU biologist Isabelle Côté has co-authored a new study that finds little would be lost by eliminating high seas fishing.

Experts Share Findings on Role of Microbes in Ocean Ecosystems at AAAS Symposium

Microbes in the ocean take up massive amounts of carbon dioxide, contributing to the global carbon cycle and affecting climate change. These microbes are abundant, diverse and critical to the health of ecosystems, but they are very hard to study. Innovations in sequencing technologies and techniques are allowing scientists to break open the so-called 'black box' of ocean microbes and revolutionizing science in the ocean.

Busy Traffic Lights Increase Exposure to Polluting Nanoparticles

UK commuters spend an average of about 1.5 hours a day at the wheel. Road vehicles in particular are known to emit polluting nanoparticles which contribute to respiratory and heart diseases.

Novel Concentrating Photovoltaic/Concentrating Solar Power Hybrid System Utilizes Waste Dissipated Heat

In concentrating photovoltaic (CPV) systems only a small part of the incident solar energy can be converted into electricity and the majority of the incident energy is dissipated as waste heat. Although the waste heat could be utilized in conventional CPV/thermal systems, the applications are seriously limited due to the low temperature accompanying the waste heat.

New EPA Program May Underestimate Methane Emissions from the Natural Gas Industry

World leaders are working to reduce greenhouse gas emissions, but it's unclear just how much we're emitting. In the U.S., the Environmental Protection Agency (EPA) has a new program to track these emissions, but scientists are reporting that it vastly underestimates methane emissions from the growing natural gas industry. Their findings, published in two papers in the ACS journal Environmental Science & Technology, could help the industry clamp down on "superemitter" leaks.

Changes in Ocean Carbon Storage Drive Rise in Atmospheric CO2 and Global Temperatures

Published today in Nature, the study shows that carbon stored in an isolated reservoir deep in the Southern Ocean re-connected with the atmosphere, driving a rise in atmospheric CO2 and an increase in global temperatures. The finding gives scientists an insight into how the ocean affects the carbon cycle and climate change.

Air Pollution Affects Memory and Lowers IQ of Children

City smog lowers children's IQ. This is among findings from a recent University of Montana study that found children living in cities with significant air pollution are at an increased risk for detrimental impacts to the brain, including short-term memory loss and lower IQ.

Too Much Dead Wood Can Fuel Severe Wildfires, Affecting Forest Ecosystems

Healthy forest ecosystems need dead wood to provide important habitat for birds and mammals, but there can be too much of a good thing when dead wood fuels severe wildfires. A scientist with the U.S. Forest Service's Pacific Southwest Research Station (PSW) compared historic and recent data from a forest in California's central Sierra Nevada region to determine how logging and fire exclusion have changed the amounts and sizes of dead wood over time. Results were recently published in Forest Ecology and Management.

New Study Could Help Predict Frequency and Intensity of Hurricanes due to a Warmer Climate

Intense hurricanes possibly more powerful than any storms New England has experienced in recorded history frequently pounded the region during the first millennium, from the peak of the Roman Empire into the height of the Middle Ages, according to a new study. The findings could have implications for the intensity and frequency of hurricanes that the U.S. East and Gulf coasts could experience as ocean temperatures increase as a result of climate change, according to the study’s authors.
