For more than a century, national assessments of supply and demand trends for timber have helped shape perceptions of future commodity consumption and resource trends. These perceptions have guided forest policy. Since 1952, U.S. timber harvest has risen by nearly 67 percent, accompanied by growing timber inventories on both public and private lands, but there has been a decline in the critical private timberland base. The current assessment envisions forest products consumption rising 42 percent by 2050 and marked shifts in the extent and location of domestic and imported supplies. Pro- spective shifts include a temporary near-term decline in U.S. roundwood harvest and an increase in the share of consumption from imports. In the longer term, U.S. timber harvest expands by 24 percent. As a result of steady improvement in growth and pro- ductivity on U.S. forest lands, this increased harvest is accommodated by continued expansion in inventory despite decreasing area in the private timberland base.

Since Timber Assessment 1952, U.S. timber harvest has risen by nearly 67 percent, accompanied by growing timber inventories on both public and private lands but a decline in the critical private timberland base. Projections to 2050 in the fifth RPA timber assessment show the forest products sector continuing to change, with U.S. timber harvest expanding by an additional 24 percent to meet increased consumption needs. As a result of steady improvement in growth and productivity on U.S. forest lands, this harvest increment can be accommodated by continued expansion in inventory despite decreasing area in the private timberland base. Highlights Projections to 2050 show the forest products sector changing and expanding to meet a 40-percent increase in U.S. consumption of forest products by 2050. The rate of increase is less than one-third the annual rate of increase over the last 33 years owing, in part, to declining use of paper and paperboard per dollar of gross domestic product, and projected relatively stable housing starts. Increasing consumption needs would be met by (1) an increase in U.S. timber harvest of 23 percent, (2) an increase in log, chip, and product imports of 85 percent, and (3) an increase in use of recovered paper of 85 percent. With a near-term economic recession, U.S. roundwood harvest is projected to decrease in the short term, then increase. The proportion of total roundwood needed for domestic product consumption that comes from domestic timber harvest decreases from 80 to 73 percent by 2050. The remainder is provided by harvest in other countries. Per capita U.S. wood and paper product consumption will remain just under three- quarters of a ton per person per year while per capita U.S. timber harvest will decline. Consumption shifts toward pulp and paper products from a 27-percent share in 2000 to a 37-percent share by 2050, and the share of composites increases from 3 to 7 percent. Oriented strandboard (OSB) production displaces softwood plywood, further eroding the importance of solid wood products. Hardwood lumber production grows more slowly than softwood lumber production. Softwood lumber imports from Canada rise in the near term, and after 2015, softwood lumber production increasingly expands largely in the South and, to a limited degree, the Pacific Northwest. Pulp, paper, and paperboard production increases most in the South, mainly in the South-Central region. Relatively stable forest product prices are expected over the next five decades. Soft- wood sawtimber prices are projected to increase over the next 50 years, but at a rate (0.6 percent per year) considerably below that of the past 50 years (1.9 percent per year). Market-based adjustments on private timberlands plus increased imports help meet expected increases in U.S. consumption. Despite generally rising prices, stump- age markets in the West will continue to be weak for small-diameter logs. Hardwood pulpwood prices will remain relatively low but will increase at the end of the projection period with increasing limitations on availability of harvestable hardwoods on nonindus- trial private timberlands in the South. Softwood pulpwood prices will remain at or below recent depressed levels, then rise at the end of the projection. Prices for softwood and hardwood lumber will increase at about the same pace as for sawtimber. The increase rate for softwood lumber is less than for the last 50 years. Prices for oriented strand- board increase faster than for softwood plywood but remain less than the softwood plywood price. Prices for nonstructural panels and for paper and paperboard remain relatively stable through 2050. In the period to 2050, annual U.S. timber harvest is projected to increase 24 percent to 22.4 billion cubic feet. Softwood harvest is projected to increase to 13.7 billion cubic feet and hardwoods to 8.8 billion cubic feet. In addition, the consumption of hardwood agrifiber grows to about 0.1 billion cubic feet. With lumber and plywood composing a decreasing share of total forest products output, virtually all of the projected increase in U.S. harvest is in nonsawtimber trees—trees used for OSB or paper and paperboard. The overall share of harvest from nonsawtimber will increase from 44 percent in 2000 to 66 percent by 2050. The share of total harvest from nonindustrial private land will increase from 61 to 63 percent. Softwood timber inventories will increase by 53 percent, mostly on public timberlands. Hardwood inventories, almost entirely in private forests, will increase by 27 percent. Inventory changes expected for softwoods are similar across regions, but there are differences for hardwoods for which there is a decrease in the South. Over the next 50 years, the species composition is projected to remain comparable to current conditions with the exception that in the South, upland hardwood acres decrease while planted pine acres increase. For the most part, age structure of forests will shift toward a greater proportion of acres in sawtimber with the exception of decreasing sawtimber acres for private hardwood timberland in the South and for private softwood timberland in the West, although in the West, the sawtimber proportion will increase after 2020. Most (80 percent in 1997) of timber harvest takes place in the Eastern United States. Most of the expected increase in harvest will come from managed stands primarily in the South. By 2050, about 60 percent of the softwood timber harvest from private timberlands will come from plantations (both in the South and the Pacific Northwest West) that occupy about 30 percent of the softwood timberland area and less than 20 percent of the total timberland area.

Here, we review these records and the global climate teleconnections they suggest following the recent publication of the Speleothem Isotopes Synthesis and Analysis (SISAL) database. We find that low-latitude records generally reflect changes in precipitation, whereas higher latitude records are sensitive to temperature and moisture source variability. Tropical records suggest precipitation variability is forced by orbital precession and North Atlantic Ocean circulation driven changes in atmospheric convection on long timescales, and tropical sea surface temperature variations on short timescales. On millennial timescales, precipitation seasonality in southwestern North America is related to North Atlantic climate variability.

  • Autumn Precipitation Trends in the Northeast United States
    Middle States Geographer, 2000, 33:74-81 AUTUMN PRECIPITATION TRENDS IN THE NORTHEAST UNITED STATES Keith G. Henderson Department of Geography Villanova University Villanova, PA 19085 ABSTRA CT: The northeastern United States experienced significant increases in precipitation from /900- / 999 Precipitation changes have been most prominent in the autumn. In western New York and Pennsylvania. and in coastal New England, seasonal precipitation totals have risen 25-45% over the IOO-year period. Concurrent decreases in temperature indicate that early season precipitation increases may be associated with earlier upper­ level troughing, while large-scale November changes may be linked to an enhanced subtropical high pressure system. Autumn precipitation steadily increased over the century and has impacted regional hydrology. At least three major rivers have shown increased autumn flow. This impact is potentially important given that autumn is usually a time ofrising river levels before high winter and spring runoffperiods. INTRODUCTION aI., 1996).

  • A Record-Breaking Trans-Atlantic African Dust Plume Associated with Atmospheric Circulation Extremes in June 2020 Bing Pu and Qinjian Jin
    Article A Record-Breaking Trans-Atlantic African Dust Plume Associated with Atmospheric Circulation Extremes in June 2020 Bing Pu and Qinjian Jin ABSTRACT: High concentrations of dust can affect climate and human health, yet our understanding of extreme dust events is still limited. A record-breaking trans-Atlantic African dust plume occurred during 14–28 June 2020, greatly degrading air quality over large areas of −3 the Caribbean Basin and the United States. Daily PM2.5 concentrations exceeded 50 µg m in several Gulf States, while the air quality index reached unhealthy levels for sensitive groups in more than 11 states. The magnitude and duration of aerosol optical depth over the tropical North Atlantic Ocean were the greatest ever observed during summer over the past 18 years based on satellite retrievals. This extreme trans-Atlantic dust event is associated with both enhanced dust emissions over western North Africa and atmospheric circulation extremes that favor long-range dust transport. An exceptionally strong African easterly jet and associated wave activities export African dust across the Atlantic toward the Caribbean in the middle to lower troposphere, while a westward extension of the North Atlantic subtropical high and a greatly intensified Caribbean low-level jet further transport the descended, shallower dust plume from the Caribbean Basin into the United States. Over western North Africa, increased dust emissions are associated with strongly enhanced surface winds over dust source regions and reduced vegetation coverage in the western Sahel. While there are large uncertainties associated with assessing future trends in African dust emissions, model-projected atmospheric circulation changes in a warmer future generally favor increased long-range transport of African dust to the Caribbean Basin and the United States.

FLORISTIC ANALYSIS OF THE SOUTHWESTERN UNITED STATES Steven P. McLaughlin' Abstract. —A study was made of the distributions of native, terrestrial, \aseular plants occurring in 50 local floras from throughout the Basin and Range and Colorado Plateau physiographic provinces of the southwestern United States. The objectives of the study were to objectively define and describe the floristic elements —assemblages of species with roughly coincident geographic distribution —occurring in the southwestern United States and to deter- mine what such assemblages reveal about the floristic history of the region. The total flora (native, terrestrial species only) of the Southwest is estimated at 5,458 species, 77% of which were recorded in 1 or more of the local floras. Nearly 22% of these species are endemic to the study region. A majority of the species were found to be relatively rare. The average range of a species included only 4 floras, and 90% of the species were recorded from 11 or fewer floras; only 81 species (1.5%) were recorded from 50% or more of the floras.

  • National Drought Summary for July 20, 2021
    National Drought Summary for July 20, 2021 Summary Active weather prevailed across much of the South, East, and Midwest, as well as parts of the Plains, into the middle of July, followed by a southward shift in widespread shower activity. Meanwhile, a robust monsoon circulation provided limited Southwestern drought relief, particularly in parts of Arizona, New Mexico, and southwestern Colorado. Farther north and west, however, little or no rain fell in California, the Great Basin, and the Northwest, where dozens of wildfires were in various stages of containment. Smoke and other particulate matter from those fires carried downwind at various atmospheric levels, producing hazy skies and reducing air quality—in some cases thousands of miles from the points of origin. Dry weather extended eastward across the nation’s northern tier as far east as Lake Superior, while heavy rain eased or eradicated drought in the remainder of the Great Lakes region, along with the Northeast. In the driest areas of the northern and western United States, drought’s impact on water supplies, as well as rangeland, pastures, and a variety of crops, was further amplified by ongoing heat. Weekly temperatures averaged as much as 10°F above normal from the interior Northwest to the northern High Plains. On July 19, temperatures as high as 110°F were reported in eastern Montana. Another pocket of hot weather was centered over the middle Atlantic States. In contrast, near- or slightly below-normal temperatures dominated the Plains, Midwest, and South. Northeast Heavy rain extending from New York and northern Pennsylvania into parts of New England resulted in further reductions in the coverage of abnormal dryness (D0) and moderate to severe drought (D1 to D2).
