As temperatures and sea levels rise, federal agencies are working to establish a national climate service to help communities, regions and nations respond to a changing planet.

The Sun is not currently the driving force behind the observed global warming dynamics as is shown elsewhere on this website, but the "Keeling Curve" below compiles the major driving reason behind currently observed initial phases of a global warming. If the antropogenic fossil C combustion continues at the current annual level it will cause the planet average temperature to raise and pass +2°C most probably within 20 - 30 years according to leading climatologists around the world. This is a temperature point above which it is estimated by ICPP and the world climatologists that it is a temperature point behind no return.
The same scientific group is convinced that the driving causal agent behind this global warming is the increasing antropogenic fossil burning of carbon(C) let out into the atmosphere.

According to Guinness World Records, bamboo is the fastest growing plant. Some species grow at a rate of 3 feet per day or 0.00002 miles per hour!
We need to distinguish between wild trees and those that have been domesticated for rapid wood production. Domesticated trees grown in plantations are genetically selected for rapid growth, and are grown in plantations with added nutrients.
Wild trees
Eastern cottonwood, Populus deltoides, is probably the fastest growing tree in North America. In Mississippi River bottoms, height growth of 10-15 ft per year for a few years are possible. Sustained height growth of 5 ft. height growth and 1 in. diameter growth per year for 25 years is common.
Coast redwood, Sequoia sempervirens, is the fastest growing gymnosperm tree in the world. Open-grown trees may grow 4-6 ft per year in height in the age range of 4-10 years, and 2 ft per year for at least 30 years.
Other fast growing species include willows, Salix spp., other bottomland species such as American sycamore, Platanus occidentalis, and several pines, Pinus spp.
Domesticated trees
Acacia falcata. A tree planted in Sabah, Malaysia, grew 35 ft. 3 in in 13 months, or an average of 1.1 inches in height per day. Fast growing tropical trees have the entire year in which to grow, and would be expected to outgrow temperate trees on an annual basis, even if their instantaneous growth rates are not as high.
Poplar hybrids, Populus spp., have been selected for extremely rapid volume growth. They make their most rapid growth in plantations where they receive adequate fertilization and sometimes irrigation.
Loblolly pine, Pinus taeda, in plantations can grow in excess of 3 ft. in height and 1/2 to 1 inch in diameter per year for the first 10 years. Trees may reach 70 ft. in height and 10 in. diameter within the first 25 years.

![]() ![]() Acid RainAcid precipitation, also known as acid rain, is any form of precipitation—snow, rain, sleet, or hail—that contains a heavy concentration of sulfuric and nitric acids. Automobiles, certain industrial operations, and electric power plants that burn fossil fuels emit pollutants that combine with atmospheric moisture to create these acids. Acid rain can contaminate drinking water, damage vegetation and aquatic life, and erode buildings and monuments. Where was acid rain first found? More... Discuss |
![]() ![]() The American Civil War Ends at Appomattox Court House (1865)The first major engagement of the US Civil War was the First Battle of Bull Run, fought in 1861 partly on the farm of Wilmer McLean in Manassas, Virginia. A few years later, McLean moved to Appomattox Court House, a town which, coincidentally, would soon be the site of the war's effective end. It was there that Confederate General Robert E. Lee surrendered to Union General Ulysses S. Grant in McLean's parlor. Why did Grant stop Union troops when they began to celebrate the victory? More... Discuss |
![]() ![]() Eadweard J. Muybridge (1830)Muybridge was an eccentric photographic innovator who left a vast and varied body of work. He is best known for his pioneering use of multiple still cameras to photograph the stages of motion. Hired by Leland Stanford to answer the question of whether there is a moment during a horse's stride when all four of its hooves are off the ground, he developed a special shutter for his cameras and a method for triggering them sequentially. Why was he acquitted of murdering his wife's lover? More... Discuss |
