Impact of a potential 21st century “grand solar minimum” on surface temperatures and stratospheric ozone

We investigate the effects of a recently proposed 21st century Dalton minimum like decline of solar activity on the evolution of Earth's climate and ozone layer. Three sets of two member ensemble simulations, radiatively forced by a midlevel emission scenario (Intergovernmental Panel on Climate Change RCP4.5), are performed with the atmosphere-ocean chemistry-climate model AOCCM SOCOL3-MPIOM, one with constant solar activity, the other two with reduced solar activity and different strength of the solar irradiance forcing. A future grand solar minimum will reduce the global mean surface warming of 2 K between 1986–2005 and 2081–2100 by 0.2 to 0.3 K. Furthermore, the decrease in solar UV radiation leads to a significant delay of stratospheric ozone recovery by 10 years and longer. Therefore, the effects of a solar activity minimum, should it occur, may interfere with international efforts for the protection of global climate and the ozone layer.

Veterinary Medical Libraries in the 21st Century

The purpose of this volume is to present a picture of information access and delivery by United States and Canadian academic veterinary medical libraries (VMLs) to the veterinary community and others with interests in the profession. This is done by discussing the resources that are available, as well as methods of delivery of that information. Our discussion of these topics will not only point out the unique aspects of these collections and services, but will also illustrate much that is in common with all medical collections and library services. As with all libraries, the goal of VMLs is to provide high quality service while looking after the information needs of their clientele through selection, acquisition, cataloging, and dissemination of materials and familiarizing their users with these resources. In the past decade, new challenges and opportunities for information specialists stem from the impact of technology on VMLs. Our goal with this volume is to be concise, but thorough about all of these topics.
