2013 Draft National Climate Assessment
Global climate is changing, and this is apparent across the U.S. in a wide range of observations. Rising temperatures, changes in precipitation and extreme events and their causes and impacts on society and the environment are chronicled in the 2013 National Climate Assessment. A team of over 240 experts compiled the report, which is open for public comment through April 12, 2013.
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.
Sea Ice Manual

Decision Support Tools (6)
Introducing the Local Climate Analysis Tool (LCAT)
NOAA unveiled this powerful new tool in July 2013 to help users produce data-driven answers to climate-related questions. The tool helps users link local weather and water events to signals in the climate system; understand how global climate change contributes to local climate trends; and explore how climate variability contributes to local impacts. Registration is required to use LCAT.
The WestMap toolbox is an interactive web-based interface developed by the Climate Assessment for the Southwest in response to findings that stakeholders in the Western U.S. from a wide range of sectors require new forms of data, intuitive tools, and support resources to understand climate variability and to be able to incorporate this understanding into specific planning and management efforts. The toolbox includes a lengthy time series of fine-scale (~1-4 km) gridded climate data that can be aggregated to user-specified domains as well as helpful climate education information.
Paleoclimate Reconstructions for the Southwest
The longest instrumental climate records date back only about 100 years in the Southwest, a timeframe that likely does not capture the full range of climate variability. Extending the record to earlier times provides additional information on the length and severity of past droughts. This tool created by the Climate Assessment for the Southwest allows users to visualize the climate variability during the past 1,000 years or so in each climate division in Arizona and New Mexico.
Historical Hurricane Tracks
This interactive mapping application easily searches and displays global tropical cyclone data. Users are able to query storms by the storm name, Zip Code, city, state, geographic region, or latitude/longitude coordinates. Custom queries can track storms of interest and allow for data extraction and download.
Coastal County Snapshots
Coastal County Snapshots turn complex data into easy-to-understand stories, complete with charts and graphs. Users select a coastal county of interest and the website does the rest, providing information that can help communities become more resilient to coastal hazards.
Local officials can use the snapshots as a planning tool to assess their county’s resilience to flooding and understand the benefits provided by natural resources. The handouts generated by the snapshots can be a helpful educational tool when working with governing bodies and citizen groups.Current topics include flood exposure, wetland benefits, and ocean and Great Lakes jobs.
