South America Weather Forecast: Gastrointestinal Disease Likely

Climate scientists predict that climate change will lead to increased variability in precipitation over much of South America.  Research by Carlton et al (2013) on residents of northwestern rural Ecuador who rely on streams and rivers for their drinking water shows how those changes might impact water quality and associated rates of diarrhea, a water-related disease which leads to approximately 1 million deaths of young children worldwide each year.  The study further highlighted curious dynamics involving precipitation and water-borne disease.

Culture and Arctic Climate Change: A Scoping Workshop to Explore Integrative Frameworks

This workshop was motivated by the appreciation that our knowledge of the human role in the Arctic system over millennia can be refined and greatly improved through better integration of high-latitude archaeology, ice core and other re-constructions of climate parameters, and studies of the contemporary Arctic environment. The two-day workshop brought together researchers working across a range of disciplines in order to explore the complex relationship between the dynamic Arctic environment and long-term human cultural responses.

"Polluters Talk. We Walk." NGO's Make Themselves Heard at COP 19

“Polluters talk, we walk” was the chant two weeks ago, as thousands of climate change activists walked out of the 19thUnited Nations Council of Parties (COP 19) conference a day before negotiations were scheduled to end. A spokesman for Oxfam blamed negotiators for insufficient outcomes to limit global temperature rise to 2 degrees Celsius as outlined by the United Nations Intergovernmental Panel on Climate Change.

COP 19: Emissions Trading Schemes Announced in Developing Nations

Warsaw, Poland. The 19th annual Council of Parties for the United Nations Framework on Climate Change concluded here two weeks ago under the scrutiny of approximately 10,000 non-governmental organizations (NGOs).  While hopes for progress on an international carbon-cutting treaty were largely unmet, some developing nations are independently making measurable progress in the area of emissions trading schemes (ETS), a market-based approach to emissions reduction that has struggled primarily in the USA, Europe and Australia.

The Importance of Model Resolution in Global Change Biology

Biologists increasingly realize that understanding the impact of global change on biological processes requires accounting for fine-grain environmental variability (Potter, Arthur Woods, & Pincebourde, 2013). Similarly, climatologists have found that increasing the resolution of climate models typically produces better simulations of climate and precipitation…

Deriving Local Climate Information from Global Models

A farmer in the central USA and a fisherman in Maine will not experience global warming in the same way.  Dynamic interactions between cities, deserts, and forests mean that a rise in the global mean temperature doesn’t imply uniform warming of the planet.  As climate change advances, wind patterns and ocean currents will shift; the sea may swell in some places, while rivers run dry in others.  Global climate models make predictions on too broad a scale to recognize many of these effects, leaving policy makers unable to prepare their communities.  

Impacts of Aerosols on Arctic Mixed-Phase Boundary Clouds During M-PACE and ISDAC Field Campaigns: Implications for Modelling Studies

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.
