Instrumental measurements, proxy data, climate model projections

Dr. Gerry Bell, the Lead Seasonal Hurricane Forecaster at NOAA’s Climate Prediction Center, talks about the 2010 Revised Hurricane Outlook and the importance of coastal residents having a preparedness plan.
 

In 2010, global temperatures were marked by near-record warmth and strong natural variability. This is the first in a series of posts highlighting findings from the "State of the Climate in 2010" report.

Computer climate models help scientists such as Dave Dewitt predict the life cycles of individual El Niño or La Niña events and their effects on weather patterns throughout the world. While the accuracy of these models continues to improve, they still have limitations.
 

Will climate change affect frequency or intensity of El Niño and La Niña? There is still little consensus among scientists on this, explains the International Research Institute for Climate and Society’s Lisa Goddard.
 

This report presents a comprehensive appraisal of Earth’s climate in 2009, and establishes the last decade as the warmest on record. Reduced extent of Arctic sea ice, glacier volume, and snow cover reflect the effects of rising global temperature.
 

State of the Climate in 2013

On July 17, NOAA and the American Meteorological Society released the State of the Climate in 2013 report. A 24-year tradition encompassing the work of 425 authors from 57 countries, the report uses dozens of climate indicators to track patterns, changes, & trends of the global climate system.

This interactive visualization is a suite of weather and climate datasets as well as tools with which to manipulate and display them visually.
