| Resumen: |
Climate Change 2013: The Physical Science Basis is the contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. This comprehensive assessment of
the physical aspects of climate change puts a focus on those elements that are relevant to understand past, document current, and project future climate change. The assessment builds on the IPCC Fourth Assessment Report (AR4)1 and the recent Special Report on Managing the Risk of Extreme Events and Disasters to
Advance Climate Change Adaptation (SREX)2 and is presented in 14 Chapters and 6 Annexes. The chapters cover direct and proxy observations of changes in all components of the climate system, they assess the
current knowledge of various processes within, and interactions among, climate system components, which
determine the sensitivity and response of the system to changes in forcing, and they quantify the link
between the changes in atmospheric constituents, and hence radiative forcing, and the consequent detection
and attribution of climate change. Projections of changes in all climate system components are based on
model simulations forced by a new set of scenarios. The report also provides a comprehensive assessment of
past and future sea level change in a dedicated chapter. Regional climate change information is presented in
the form of an Atlas of Global and Regional Climate Projections (Annex I). This is complemented by Annex
II: Climate System Scenario Tables and Annex III: Glossary. |
