Climate mitigation policies for cities must consider air quality impacts
These urban mitigation policies aimed at reducing CO2 emissions can worsen air quality and cause premature deaths if coemitted pollutants are not accounted for.

Increased carbon dioxide suppresses AMOC variability in GFDL ESM2M simulation
Research funded by CPO’s Climate Variability and Predictability (CVP) and published in the Journal of Climate found that increased carbon dioxide suppresses variability of the Atlantic Meridional Overturning Circulation (AMOC) in GFDL ESM2M simulation.
The reinvigoration of the Southern Ocean carbon sink
COD-funded researchers attempt to answer the question “Has global warming slowed the uptake of atmospheric carbon dioxide by the Southern Ocean?” in a new study in Science.
Emissions from thawing permafrost add trillions in economic impacts
Work supported by CPO’s AC4 program found that the effects of melting permafrost in the Arctic could cost $43 trillion in extra economic damage by the end of the next century, on top of the more than the $300 trillion economic damage already predicted.
The climatic consequences of a Pine Island Glacier collapse
New CVP-funded research published in the Journal of Climate by Green and Schmittner simulates the consequences of a rapid collapse of the Pine Island Glacier (PIG) under pre-industrial and anthropogenically-forced conditions.
Seasonal variations in the aragonite saturation state in the upper open-ocean waters of the North Pacific Ocean
A paper supported by CPO’s Climate Observation Division (COD) was published in Geophysical Research Letters. The paper–Seasonal variations in the aragonite saturation state in the upper open-ocean waters of the North Pacific Ocean–was published online on June 16, 2015.
Semi-arid regions may be key to understanding and predicting variations in the land CO2 sink
Terrestrial ecosystems pull about one-fourth of anthropogenic CO2 emissions out of the atmosphere per year, serving as a sink for CO2 since industrialization.
Climate Change and the Permafrost Carbon Feedback
New research supported by CPO’s AC4 program has been published in Nature. “Climate Change and the Permafrost Carbon Feedback” focuses on the large quantities of organic carbon are stored in frozen soils within arctic and sub-arctic regions.
CarbonTracker CT2013B Update
CarbonTracker, a CO2 measurement and modeling system developed by NOAA to keep track of sources (emissions to the atmosphere) and sinks (removal from the atmosphere) of carbon dioxide around the world, has come out with its latest update: CT2013B. This effort is supported by CPO’s AC4 Program.
CarbonTracker-CH4: An assimilation system for estimating emissions of atmospheric methane
CarbonTracker methane, an off-shoot of NOAA’s highly successful CarbonTracker, which was partially funded by CPO’s AC4 program, has earned peer-reviewed status with a recent paper in Atmospheric Chemistry and Physics.
