A review of the present status of the global warming science is presented in this paper. The term global warming is now popularly used to refer to the recent reported increase in the mean surface temperature of the earth; this increase being attributed to increasing human activity and in particular to the increased concentration of greenhouse gases (carbon dioxide, methane and nitrous oxide) in...

Recent studies by the United Nations Environment Programme (UNEP) and the Intergovernmental Panel on Climate Change (IPCC) indicate that Vietnam is one of the countries most affected by climate change. The variability of climate in this region, characterized by large fluctuations in precipitation and temperature, has caused significant changes in surface water resources. This study aims to proj...

Until recently, Intergovernmental Panel on Climate Change (IPCC) emission factor methodology, based on simple empirical relationships, has been used to estimate carbon (C) and nitrogen (N) fluxes for regional and national inventories. However, the 2005 USEPA greenhouse gas inventory includes estimates of N2O emissions from cultivated soils derived from simulations using DAYCENT, a process-based...

The 2009 Annual Meeting of the International Pachyonychia Congenita Consortium (IPCC)* centered on the need to develop patient-friendly technologies to effectively and efficiently deliver nucleic acids to skin. The IPCC is a group of physicians and scientists who have agreed to work together to develop therapeutics for the rare skin disorder pachyonychia congenita (PC) (a list of IPCC members c...

We use a simple climate model to assess climate sensitivity as temperature response to heat forcing. How wonderful that we have met with a paradox. Now we have some hope of making progress. (Nils Bohr) Some aspects of climate have not been observed to change. (IPCC Summary for Policymakers 2007) 1 IPCC Climate Sensitivity and Global Warming Climate science as presented by IPCC [2] is based on a...

El cambio climático, su origen antropogénico y su presencia a pesar de cualquier acción de reparo son hechos incontrovertibles para un gran número de sociedades cientı́ficas, ası́ como para el Intergovernmental Panel on Climate Change (IPCC) auspiciado por Naciones Unidas. El IPCC-2007 ha sintetizado los resultados de 23 modelos de circulación general atmosférica-oceánica para predecir el futuro ...
