NOAA’s Climate Prediction Center (CPC) has issued its 2013 Atlantic hurricane seasonal outlook. In this video, Gerry Bell, a NOAA CPC meteorologist, explains that as of May 23, 2013, the outlook favors an above-normal Atlantic hurricane season from June 1 through November 30.
The Spring Outlook encompasses temperature, precipitation, drought, and flooding expectations for the coming three months, and Mike Halpert, Acting Director of the Climate Prediction Center, discusses the outlook and its implications.
We can’t immediately link Hurricane Sandy itself to climate change, says climate scientist Cynthia Rosenzweig, but the flooding damage we can. Partly due to global warming, sea level has climbed about a foot in the NYC area over the past century, giving storm surges a “step up” along the coast.
Since the mid-1950s, easy-to-serve, portion-controlled fish sticks have regularly found their way onto U.S. dinner tables and into school lunches. The past decade, however, has given fishermen and scientists a preview of the challenges they may face in keeping fish sticks on the menu as the planet gets warmer.
Alabama farmer Myron Johnson talks about how adding seasonal climate outlooks to his decisions about when to plant and harvest his cover crops helped produce a bumper cotton crop during the 2010 growing season.
Although they are related, meteorology and climatology have important differences, particularly in how scientists develop and use weather and climate models. What makes climatologists think they can project climate scenarios decades into the future when meteorologists cannot accurately predict weather more than two weeks in advance? This presentation by Wayne Higgins of NOAA's Climate Prediction Center clarifies the relationships and differences between weather and climate, as well as the differences between natural climate variability and human-induced climate change.
James Roger Fleming presents a historical perspective on how our understanding of Earth's climate system developed through innovations and discoveries by pioneering scientists in the 1800s and 1900s who asked and answered fundamental questions about the causes and effects of global climate change.
Climate scientist Michael MacCracken explores some of the scientific, legal, and ethical implications of "geo-engineering" options that have been proposed by some people to address global climate change.
Humans currently release about 70 million tons of carbon dioxide every day into the atmosphere and about 20 million tons is being absorbed regularly by the oceans, causing the pH to drop. Chris Sabine describes current and projected future impacts of this acidification on marine ecology.
