The 2012 Arctic summer sea ice extent is the lowest since taking measurement. In a new three-part video series
from NOAA Ocean Today, learn about sea ice and why it is so important; how scientists are detecting and measuring change in sea ice; and the impacts of shrinking Arctic sea ice.
Part I: What is sea ice and why is it shrinking?
Part II: How do we measure ice?
Part III: Shrinking ice: Impacts
CPO's John Calder, Kathy Crane, Rebecca Lindsey, and Diane Stanitski contributed to the production of these videos. They are available for download on the Ocean Today website.
Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2011, the United States experienced a record high number (14) of climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 670 lives, caused more than 6,000 injuries, and cost $55 billion in damages. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
