UN Climate Change Learning Partnership Releases Learning Resources Guides on Climate Change Science
The UN Climate Change Learning Partnership released two resource guides to help people understand the science of climate change. The two guides provide a tour of the best & most relevant resources on climate change science.
Climate Change 2013: The Physical Science Basis
On September 27, 2013, Working Group I of the Intergovernmental Panel on Climate Change (IPCC) presented its report to member governments for approval and acceptance. The report is the first of four that will make up the IPCC's 5th Assessment.
Metadata Access Tool for Climate and Health (MATCH)
The U.S. Global Change Research Program recently launched the Metadata Access Tool for Climate and Health (MATCH). The tool offers centralized access to metadata about thousands of government-held datasets related to human health, the environment, and climate science for researchers and decision makers. MATCH is easily searchable and browsable by topic, keyword, and region, allowing users to quickly find resources of interest and relevance, including monitoring and surveillance datasets, early warning systems, and tools for characterizing climate-related human health impacts.
Climate Change 2007: Mitigation of Climate Change
A comprehensive scientific assessment providing an in-depth analysis of the costs and benefits of different approaches to mitigating and avoiding climate change.
State of the Climate in 2010
Over 360 authors from 45 countries contributed to this comprehensive appraisal of the Earth’s climate. Observations from pole-to-pole show climate patterns such as La Niña and El Niño contributed to some climate events this year. Trends consistent with manmade climate change over the last 50 years are also continuing. These include warming temperatures, melting glaciers and saltier seas, which are related to rising atmospheric greenhouse gas concentrations.
Atmospheric Aerosol Properties and Climate Impacts
A detailed look at global distributions and properties of airborne particles known as "aerosols." The report examines the various ways in which aerosols influence climate, and the uncertainties in our ability to observe and measure these particles' impact on the climate system.
Abrupt Climate Change
An assessment of abrupt climate change events where key aspects of Earth's climate system change faster than the responsible forcings would suggest and/or faster than society can respond. This report examines four types of abrupt change in Earth's past that were so rapid and so large in their impact that if they were to recur today they would pose clear risks to society in terms of our ability to adapt.
Climate Projections Based on Emissions Scenarios for Long-Lived and Short-Lived Radiatively Active Gases and Aerosols
An assessment of the effects of short-lived gases and particles in the atmosphere. They can significantly change regional surface temperatures. By the year 2100 short-lived gases and particles may account for as much as 40 percent of the warming over the continental U.S. in summertime.
Climate Models: An Assessment of Strengths and Limitations
Scientists use mathematical models of Earth's climate, run on the most powerful computers available, to examine hypotheses about past and present-day climates. This report describes the models and their ability to simulate climate.
Reanalysis of Historical Climate Data for Key Atmospheric Features: Implications for Attribution of Causes of Observed Change
A reanalysis combines a diverse array of past observations together within a model to derive a best estimate of how the climate system has evolved over time. The goal is to provide consistent and reliable long-term datasets of temperatures, precipitation, winds, and many other climate variables.
The First State of the Carbon Cycle Report
A synthesis of the current knowledge of North America's carbon budget and its context within the global carbon cycle. This report provides scientific information for decision support focused on key issues for carbon management and policy.
Scenarios of Greenhouse Gas Emissions and Atmospheric Concentrations
The findings presented in this report draw from scenarios designed to stabilize the influence of a suite of greenhouse gases. Three climate-modeling groups independently developed a reference scenario and then developed four contrasting stabilization scenarios for comparison.
Climate Change 2007: The Physical Science Basis
A comprehensive and up-to-date scientific assessment of past, present, and future global climate change. The assessment confirms that the scientific understanding of the climate system and its sensitivity to greenhouse gas emissions is now richer and deeper than ever before. The chapters forming the bulk of this report describe scientists assessment of the state-of-knowledge in their respective fields.
Temperature Trends in the Lower Atmosphere: Steps for Understanding and Reconciling Differences
This report addresses previously identified discrepancies between observations and simulations of surface and atmospheric temperature trends. It is an important revision to the conclusions of earlier reports from the U.S. National Research Council and the IPCC.
Decision Support Tools (4)
Habitat Priority Planner
This free PC-based tool from NOAA's Coastal Service Center aids in decisions about conservation, restoration, and planning. The Habitat Priority Planner takes away much of the subjective nature of the process by providing critical habitat analyses that are consistent, repeatable, and transparent. The program allows users to easily test various ideas and "what if" scenarios on the fly, making it the perfect tool to use in a group setting.
Impervious Surface Analysis Tool
The Impervious Surface Analysis Tool (ISAT), which is available as a geographic information system extension, is used to calculate the percentage of impervious surface area within user-selected geographic areas (e.g, watersheds, municipalities, subdivisions). In small watersheds, the correlation between an increase in impervious surfaces and a decrease in water quality has been well established. People use the information derived from ISAT to predict how different management scenarios might impact local water quality.
OpenNSPECT, an open-source version of the Nonpoint-Source Pollution and Erosion Comparison Tool (N-SPECT), is a plugin to the free MapWindow GIS open-source platform. Enhancements in this version of N-SPECT include faster processing time, additional coefficients for common land cover data products, and a comparison function to evaluate differences in land use scenarios.
CanVis is a visualization program used to see potential impacts from coastal development or sea level rise. Users can download background pictures and insert the objects (hotel, house, marina, or other objects) of their choosing. The free PC-based software is used by municipalities to brainstorm new ideas and policies, undertake project planning, and make presentations.
