Communicating Climate Change Scenarios With Decision Makers: Lecture by Dr. Holly Hartmann, Research Hydrologist
In this 1-hour lecture, presented in three parts, research hydrologist Dr. Holly Hartmann discusses issues and approaches for communicating with decision-makers regarding climate change topics in water management and planning. Dr. Hartmann is a national leader in research related to the development of decision support tools for climate, water, and other resource management applications, especially linking research with the needs of decision-makers and moving research into agency operations. Dr. Hartmann is Carpe Diem West’s Director of Climate Science Applications. Previously she was Director ...
Overview of Watershed and Channel Sedimentation
This lesson provides an overview of the primary influences of watershed and channel sedimentation. In a short narrated portion of the lesson, we explore a section of the Rio Grande watershed and channel in New Mexico using Google Earth imagery, river profiles, and graphic animations. We highlight features of the upland catchments, the river channel, and the Elephant Butte Reservoir. We then demonstrate how environmental factors (climate, geography, land use changes, reservoirs) impact the supply and movement of sediments for the Rio Grande and other rivers. The focus is on the three primary pr ...

Creación de capacidad en la evaluación de modelos y en el apoyo a la toma de decisiones del CORDEX
Los informes de evaluación del clima en los ámbitos estatal, nacional e internacional son importantes a la hora de ofrecer una base científica que permita comprender y evaluar los impactos de la variabilidad climática y del cambio climático en sectores económicos tales como la agricultura y la alimentación, los recursos hídricos, la energía y el transporte.

Preparing Hydro-climate Inputs for Climate Change in Water Resource Planning
This lesson describes the process of selecting the best available climate projection information and using it to develop “climate-adjusted weather” inputs to be used for modeling climate change impacts. These modeled impacts can be used for planning of future water resources. Specific steps of this process include: 1) Recognizing the general science and terms associated with Atmosphere-ocean General Circulation Models (AOGCMs); 2) Making AOGCMs more regionally applicable through bias correction and downscaling; 3) Determining climate change scenarios based on climate projections and selecting ...

Multi-model climate change projections for India under representative concentration pathways: In Current Science, vol.103, issue 7 (10/10/2012)
Climate projections for the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) are made using the newly developed representative concentration pathways (RCPs) under the Coupled Model Inter-comparison Project 5 (CMIP5). This article provides multi-model and multi-scenario temperature and precipitation projections for India for the period 1860–2099 based on the new climate data. We find that CMIP5 ensemble mean climate is closer to observed climate than any individual model. The key findings of this study are: (i) under the business-asusual (between RCP6.0 and RCP8.5 ...
Southern African rainfall physical mechanisms and projected Climate Change with a special focus on Zimbabwe
Aimed at understanding the physical mechanisms driving rainfall systems in southern Africa with a particular focus on Zimbabwe, this research is a step towards improving the representation of those systems in Climate Models leading to improved Rainfall projections. Because RCMs such as PRECIS are good at resolving subtle systems which modify local climates and possibly mask the anticipated anthropogenic induced (rainfall) change, its use in regions such as Zimbabwe that have complex terrain is crucial. Understanding the physical mechanisms that control rainfall in the current climate also prov ...
Capturing Recent Climate Variations in the Extreme Southern Caribbean with Projections for the Near and Medium Terms: A Downscaling Approach for Trinidad and Tobago
To mitigate adverse effects of future extremes in climate in the extreme southern Caribbean and Trinidad and Tobago require a sound understanding of the science of the climate, along with realistic and region specific projection outputs; in order that an effective response can be provided by respective regions. As a step towards achieving this, downscaling GCM outputs through RCMs is useful at the local and regional scales because it can provide finer detailed and more user friendly output required for planning. Moreover, it is an avenue through which more profound understanding of the ...
Lesotho Climate Change Projections
Lesotho is a small mountainous country is southern Africa. Lesotho is a temperate region that has four distinct seasons; spring, summer, autumn and winter. It is among countries that are vulnerable to climate change impacts. As such, future climate projections are vital to the country. Lesotho has submitted her first and the only report (FNC) to the United Nations Framework Convention on Climate Change (UNFCCC) in 2000. The report includes vulnerability and adaptation (V&A) assessment developed using the first generation low resolution Global Climate Models (GCMs) output. This study was aimed ...

Testing Climate Models for Agricultural Impacts : recent Trends, Current Projections, Crop-Climate Suitability, and Prospects for Improved Climate Model Information
CCAFS, 2012Good climate projections for agriculture can help guide investments in risk management and adaptation. New reports offer insights into the reliability of future climate projections for agriculture, and show how to make the most of current data.
How trees and people can co-adapt to climate change : reducing vulnerability in multifunctional landscapes
In this section we provide a more in-depth look at the role trees play in the provision of goods and services in multifunctional landscapes. Tree growth is, however, vulnerable to climate variability, depending on the physiological properties of the tree and characteristics of the site. A further quantification of climate variability and climate change is needed to advise on what types of trees can be grown where, to be ready for the likely local climate-change during their lifetime. This leads to a discussion of the two-way relationship between climate change adaptation and rewards for enviro ...

Climate: observations, projections and impacts
The Met.Office, 2011Understanding the potential impacts of climate change is essential for informing both adaptation strategies and actions to avoid dangerous levels of climate change.
But assessing the impacts is scientifically challenging and has, until now, been fragmented. To date, only a limited amount of information about past climate change and its future impacts has been available at national level, while approaches to the science itself have varied between countries.
In April 2011, we were asked by the United Kingdom's Secretary of State for Energy and Climate Change to begi ...
