National Oceanic and Atmospheric Administration (NOAA), United StatesLast Updated on 2013-10-12 23:55:15
The National Oceanic and Atmospheric Administration (NOAA) is a federal agency within the United States Department of Commerce. As a science-based operational agency tasked with monitoring climate and changes in the environment, NOAA is responsible for the study of the atmosphere and the oceans. The agency issues daily weather forecasts and storm warnings, restores coastline, aids the flow of marine commerce, and manages fisheries. NOAA's activities facilitate weather- and climate-sensitive economic activity that account for roughly one-third of the country's gross domestic product (GDP). The agency also responds to natural and man-made maritime disasters, operates a complex network of oceanographic, meteorological and atmospheric data-collecting products and services, and manages marine mammals, marine endangered...

National Forest System (NFS) Roadless Area InitiativesLast Updated on 2013-09-30 17:30:22
Roadless areas in the U.S.National Forest System (NFS) have received special attention for decades. Many want to protect their relatively pristine condition; others want to use the areas in more developed ways.
Two different roadless area policies have been offered in the last decade. On January 12, 2001, the Clinton Administration’s roadless area policy established a nationwide approach to managing roadless areas in the National Forest System to protect their pristine conditions. The Nationwide Rule, as it will be called in this report, generally prohibited road construction and reconstruction and timber harvesting in 58.5 million acres of inventoried roadless areas, with significant exceptions. The Bush Administration initially postponed the effective date of the Nationwide Rule, then issued its own rule that allowed states to plan how roadless areas were managed. It issued a... More »
Alberta Mountain forestsLast Updated on 2013-09-18 20:20:02This ecoregion lies almost wholly within Alberta but hugs the Alberta-British Columbia border from Banff northward to Jasper and Kakwa.
Mean annual temperature in the Eastern Continental Ranges is 2.5°C, mean summer temperature is 12°C and mean winter temperature is -7.5°C. Precipitation increases from east to west with elevation, from 600-800 millimeters (mm) per year. Valley regions are marked by warm, dry summers and mild, snowy winters, and subalpine areas have cool, showery summers and cold, snowy winters.
This region covers the Rocky Mountains of Alberta, incorporating the eastern flanks of the Continental Ranges. The major peaks cluster around the Columbia Icefield, the largest ice field in the Rocky Mountains. The ranges themselves are linear with great cliffs and precipitous faces of thick sections of gray carbonate strata, and peaked by rock... More »
Africa's future: driving forcesLast Updated on 2013-09-10 15:54:33
The development of scenarios is based on the identification and articulation of some underlying factors – the driving forces. Driving forces are elements that cause change to occur and their unfolding and interaction is responsible for the trends envisaged in each scenario. Some driving forces are not directly controllable and these have to be addressed in the scenario. Controlled forces are those that can be shaped and these form the basis for the recommendations and means of implementation prescribed in the scenarios. Driving forces are sufficiently strong to direct the course of growth of the society and change in environment. They set the initial course for development, and their impacts are potent enough to change the course of development. Therefore, they define departure points for the environmental issues that they influence. Their effects can be short and sharp, or... More »
Fisheries and aquaculture in the Central North Atlantic (Iceland and Greenland)Last Updated on 2013-09-05 00:41:11
This is Section 13.3 of the Arctic Climate Impact Assessment
Lead Authors: Hjálmar Vilhjálmsson, Alf Håkon Hoel; Contributing Authors: Sveinn Agnarsson, Ragnar Arnason, James E. Carscadden, Arne Eide, David Fluharty, Geir Hønneland, Carsten Hvingel, Jakob Jakobsson, George Lilly, Odd Nakken,Vladimir Radchenko, Susanne Ramstad,William Schrank, Niels Vestergaard,Thomas Wilderbuer
This section deals with the marine ecosystems of Iceland and Greenland. Although there are large differences, both physical and biological, between these two ecosystems there are also many similarities.Seafood exports represent a major source of revenue for both Iceland and Greenland. Figure 13.5 shows the locations of the sites referred to most frequently in the text.
