Includes sea level rise; extreme weather; changes to ecosystems, plants and animals; melting ice and permafrost; ocean wamring; impacts to water resources, agriculture, public health and national security
For the record books: A review of the ten most significant or unusual global climate or weather events of 2011, as ranked by NOAA’s National Climatic Data Center in its yearly review of the Earth’s climate.
It’s natural to associate drought with heat and with summer, but drought also impacts us during winter months. Winter wheat yields are declining, and the Mississippi River is approaching an all-time low. Understanding drought conditions and how they are affecting us is part of being “climate smart.”
It may seem remote from our everyday lives, but the Arctic exerts a powerful influence on the rest of the planet. From rising sea level, to U.S. and European weather, to bird migrations, NOAA Administrator Jane Lubchenco describes how Arctic climate change can influence the rest of the planet.
NOAA released the 2012 installment of the annual Arctic Report Card on December 5, 2012, as part of the American Geophysical Union's fall meeting. This image collection is a gallery of highlights based on the report's major themes. It was developed by the NOAA Climate.gov team in cooperation with Arctic Report Card authors and other Arctic experts.
On a yearly basis, Arctic temperatures are strongly influenced by natural climate patterns, including the Arctic and North Atlantic Oscillations. Over the span of a decade, though, Arctic amplification of climate change is evident: no part of the Arctic was cooler than the long-term average.
At the edge of southern Louisiana sits Port Fourchon—the hub through which 20 percent of our nation’s oil and gas supplies are distributed to the rest of the country. The only road leading to and from this major port is the Louisana-1 Highway. A drive down the LA-1 through a vulnerable but vibrant coastal landscape shows what is at stake if ‘America’s longest main street’ fails to stay above water.
A collection of tools and information from the NOAA Coastal Service Center for coastal communities to help them better understand and address the inundation issues. The kit specifically includes a crash course in key concepts related to inundation, visualization and risk recognition tools, and resources to help explain the consequences of coastal inundation and the benefits of preparing for it.
For James Overland, an Arctic oceanographer at NOAA’s Pacific Marine Environmental Laboratory, six exceptionally slushy summers in a row in the Arctic demanded an explanation that went beyond the obvious: that global warming is raising the Arctic’s temperature. After analyzing winds and pressure patterns, Overland and several colleagues documented an unusual shift in the prevailing June winds—from westerlies to southerly—that amplified Arctic warming and sea ice melt.
