Comprehensive data on arctic boundary layer aerosol and cloud microphysical and radiative properties were collected during the 2004 Mixed-Phase Arctic Cloud Experiment (M-PACE) and the 2008 Indirect and Semi-Direct Aerosol Campaign (ISDAC). During M-PACE, the University of North Dakota Citation executed spiral ascents and descents through 27 mixed-phase clouds on 7 separate days over ground-based remote sensing sites at Barrow and Oliktok Point, Alaska.

Even before the climate negotiations began this week, Typhoon Haiyan sent a message to the world – a message that is still making waves. The strength and trajectory of Typhoon Haiyan was unprecedented, even for the Philippines, an island nation that experiences more disasters than most. In response, the lead Filipino negotiator declared a fast for the duration of the climate negotiations until progress has been made to “stop this madness.”

Dry regions, where evaporation and evapotranspiration exceed the annual mean precipitation, cover about 40% of Earth’s land surface and affect the livelihood of …
Anthropogenic climate change is predicted to dramatically alter biodiversity and species distributions around the globe, particularly if many species are unable to disperse to new habitats or evolve and adapt to new climatic conditions in their current habitat.
The ability to predict future climate relies heavily on our understanding of past climates. We can view these ancient climates as natural experiments that provide a range of examples for the behavior of the Earth’s climate system, enabling us to understand how the climate system responds to forcings. A wide variety of methods have been developed to study these natural experiments.
With the atmospheric CO2 level just reaching the hallmark value of 400 parts per million this May, a key question is how much global temperature change we should expect in the near and distant future…
When will the summer Arctic be nearly sea ice free? The answer is “eventually” given anthropogenic warming, but different considerations of the available data yield different answers. Overland and Wang address this question and attempt to predict 21st century summer Arctic sea ice loss by applying three distinct approaches to the problem…
New insight into the origin of monsoons, the potential use of aerosols to cool the globe, and how different industries uniquely impact atmospheric warming are the contributions of YCEI researchers at an upcoming forum on Global Climate and Atmospheric Modeling, Saturday, September 21, at KGL. Researchers from Tokyo’s Todai University round out the 5-person forum with talks on the radiative forcing of aerosols in East Asia and a model of 100,000-year glacial-interglacial cycles. The forum starts at 1 p.m.
Joseph Messina is Professor of Geography and Acting Director of the Center for Global Change and Earth Observations at Michigan State University. He holds a Ph.D. in Geography from UNC- Chapel Hill (2001). He has worked in the Amazon, SE Asia, and East Africa on human – environment interactions, infectious diseases, and land change science. In Michigan, he explores issues related to health care access and recently co-authored a new standard for hospital services.
