This study investigates the use of Geospatial Web 2.0 and Global Climate Models for climate change communication. The aim of this research has been to integrate the data, models, and tools of climate science with Geoweb to advance climate change communication.

This paper studies the cost effectiveness of climate policy if there are technology externalities. For this purpose, we develop a forward-looking CGE model that captures empirical links between CO2 emissions associated with energy use, directed technical change and the economy. We find the cost-effective climate policy to include a combination of R&D subsidies and CO2 emission constraints, although R&D subsidies raise the shadow value of the CO2 constraint (i.e. CO2 price) because of a strong rebound effect from stimulating innovation. Furthermore, we find that CO2 constraints differentiated t

A thermal model is developed to find the distribution of stable near-surface ground ice on Mars that is in diffusive contact with the atmosphere for past and present epochs. Variations in the orbit of Mars are able to drive climate changes that affect both surface temperatures and atmospheric water content so the distribution of ground ice will vary significantly in past epochs. A technique is developed to correct the average water vapor density above the surface for depletion due to diurnal frost formation.

Abstract:
Climatic fluctuation is putting Nigeria’s agriculture system under serious threat and stress. The study of the effect of climate change on agricultural productivity is critical given its impact in changing livelihood patterns in the country. Descriptive and co-integration analysis are the techniques used to analyze the Time series data used in this work. The finding demonstrates that the rate in agricultural productivity is persistently higher between 1981 and 1995, followed by a much lower growth rate in the 1996–2000 sub period. There was variation in the trend pattern of rainfall. Temperatu

Abstract:
We study a discrete time, structured population dynamic model that is motivated by recent field observations concerning certain life history strategies of colonial- nesting gulls, specifically the glaucouswinged gull ( Larus glaucescens). The model focuses on mechanisms hypothesized to play key roles in a population's response to degraded environment resources, namely, increased cannibalism and adjustments in reproductive timing. We explore the dynamic consequences of these mechanics using a juvenile- adult structure model. Mathematically, the model is unusual in that it involves a high co- di

Abstract:
Frequent droughts and sub-optimal crop management have been identified as the principal constraints on agricultural intensifcation in the Sahel. A new model, the Crop Model for Sahelian Adaptation Studies (CROMSAS), was developed to examine the influence of climatic variability, climate change and crop management strategies on millet yields. To improve the simulation of environmental stresses, several original features were implemented including a new leaf expansion methodology, semi-independent tillers, stress-dependent partitioning, and intercropping. CROMSAS was designed in a structured, ac
