New Study Examines Factors Challenging Our Ability to Detect Long-term Trends in Ocean Chlorophyll
With Global climate change expected to alter the ocean’s biological productivity with implications for fisheries and climate, a recent study examines the factors challenging our ability to detect long-term trends in ocean chlorophyll. The study highlights the importance of maintaining continuous, climate-quality satellite data records for climate change detection and attribution studies.

Study Looks at Respnse to CO2 doubling of the Atlantic Hurricane Main Development Region in a High-Resolution Climate Model
In a recent study, a team of researchers led by former AOS postdoc Takeshi Doi simulated the response of sea surface temperature (SST) in the Atlantic Hurricane Main Development Region (MDR) to a doubling of CO2, using a cutting-edge global high-resolution coupled model developed at GFDL (CM2.5). The study, published online in the Journal of Climate, can be found here.

Recent Study Examines the Role of ENSO, Season, and Variability in Atmospheric CO2 Response to Volcanic Eruptions
Tropical explosive volcanism is one of the most important natural factors that significantly impact the climate system and the carbon cycle on annual to multi-decadal time scales. A team of reseachers, led by AOS Postdoctoral Research Associate Thomas Frölicher, determine for the first time the extent to which initial conditions, i.e., season and phase of the ENSO, and internal variability influence the coupled climate and carbon cycle response to volcanic forcing and how this affects estimates of the terrestrial and oceanic carbon sinks. The study, published online in Global Biogeochemical Cycles on March 27, 2013 can be found here.
Study Demonstrates the Nonlinear Effect of Biomass Burning Strength on Radiative Forcing
A team of researchers led by AOS Associate Research Scholar Jingqiu Mao use a fully coupled chemistry-climate model (GFDL AM3) to demonstrate the nonlinear effect of biomass burning strength on radiative forcing in a recent study published in Geophysical Research Letters. At present-day emission levels, biomass burning produces atmospheric cooling, but increasing emissions to over 5 times present levels would result in warming. The study was published online on March 26, 2013. GFDL Research Highlights can be found here.
Congratulations to AOS Graduate Student Ilissa Ocko on her selection for the Emerging Alumni Scholars Award for 2012-2013.

Recent NOAA Study Estimates Future Loss of Labor Capacity as Climate Warms
Our GFDL partners have released a new study that projects the doubling of heat-stress related labor capacity losses globally by 2050 with a warming climate. The study uses existing occupational health and safety thresholds to establish a new metric to quantify a healthy, acclimated individual's capacity to safely perform sustained labor under environmental heat stress. Coauthors of the study include GFDL Scientists John Dunne (lead author), Ronald Stouffer, and Jasmin John. The research was published online on February 24, 2012 in Nature Climate Change.

New Study Finds that Global Snowfall will Reduce, but Certain Regions will Receive More Snow under 2xCO2
AOS Postdoctoral Research Associate and CICS Scientist Sarah Kapnick is the lead author of a new study in the Journal of Climate that showcases the ability of the new high-resolution CM2.5 GFDL model for simulating snow variables. It examines the response of snowfall and snow covered area to a doubling of CO2 (translating to ~5F warming globally), finding that global snowfall reduces, but some special regions receive more snow.

Recent Study Discovers New Role of Aerosols
A team of researchers led by AOS Associate Research Scholar Jingqiu Mao has discovered a major and previously unrecognized role of aerosols in atmospheric oxidant chemistry. According to Mao,"This work solves a long-standing problem of underestimating air pollutants (carbon monoxide) transport to the Arctic in global chemistry models and also suggests a previously unrecognized positive radiative forcing of aerosols through the effects on the chemical budgets of major greenhouse gases including methane and hydrofluorocarbons (HFCs).” The paper, published on January 16 in Atmospheric Chemistry and Physics, can be found here.

Sarmiento and Study of Southern Ocean featured on PEI's Home Page
Jorge Sarmiento discusses the Southern Ocean and its relevance to climate change. Whether it's the economics of clean energy, the politics of Washington or claims over the severity of the problem itself, the debate over climate change is loud and crowded. One aspect that often goes overlooked is the Southern Ocean ringing Antarctica at the bottom of the globe. But that, says Jorge Sarmiento, is about to change. Read more
