“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.
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.
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…
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.
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.”

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.
