European Stars and Stripes (Newspaper) - January 06, 1991, Darmstadt, Hesse Scientists Hunt for disappearing Carbon dioxide Donald Smith National geographic Here in the world is All the Carbon dioxide going. Scientists have been watching an apparent ecological magic trick for years. By burning Fossil fuels humans have pumped billions of tons of Carbon into the atmosphere in the form of Carbon Dion rdc a a a a if All that Gas remained in the air it would cause considerable trouble a trapping heat and hastening the suspected global warming trend for a substantial portion of the Gas has mysteriously disappeared. A a there a a huge imbalance a says Lee Klinger of the National Center for atmospheric research in Boulder Colo. A a there a much More Carbon dioxide being released than can be accounted for Quot the Hunt for the Carbon a sink a As scientists Call the unknown mechanism that accounts for most of the disappearance is More than a matter of satisfying scientific curiosity As International pressure builds in favor of setting global limits on Carbon dioxide emissions scientists Are being called upon to predict future Levels of the Gas. Reliable predictions arc vital because such limits Are Likely to Cost Money and jobs. Until the Carbon sink is found and understood scientists say that such accuracy May be impossible. One alarming theory is that vast quantities of Carbbit dioxide now being stored somewhere on the planet could be released suddenly by some triggering event with potentially catastrophic results. One possible site of a sudden release of Carbon dioxide is the Ocean which for years has been storing dissolved Carbon at great Depths. A i hesitate at being an alarmist a says David m. Glover of the Woods Hole oceanographic Institute. A but if the Ocean starts to warm up its pos Siulc that this dissolved organic Carbon will break Down and release a sizable amount of Carbon dioxide. The possibility is quite distinct but we need More research because its very poorly tinder a /. Quot. \ a. Such a hypothetical eruption raises the Specter of a global disaster similar to a Small one that occurred in 1986 Lake nos in the cameroons in West Africa. In what some blame on a violent event such As a. Volcanic eruption lands id or Earth tremor the Lake spewed Carbon dioxide that had been stored on its Bottom. It was like uncorking a warm bottle of Champagne. Some 1,700 people died As a ground tugging Cloud of invisible Gas crept across the land a similar eruption at nearby Lake Mono Unin 1984 killed 37 people. The oceans have Long been suspected As a major depository of Carbon. Through photosynthesis Carbon dioxide is consumed by phytoplankton microscopic Ocean plants. When Plankton die their husks sink to the Bottom. Each carries a tiny amount of Carbon with it. But recent studies indicate that the oceans cannot account for the bulk of the vanishing Carbon dioxide. A it now appears that very Little is going into the oceans a says Pieter p. Tans of the National. Oceanographic and atmospheric administration. Tans has been measuring the amount of Carbon dioxide released in the atmosphere and the amount of Carbon found there. A most of it is going into Continental land masses at temperate latitudes in the Northern hemisphere a he said. A but its not like we be found the smoking gun. We still done to know exactly where its terrestrial plants also absorb Carbon dioxide / through photosynthesis. But scientist say it will be difficult to identify specific plants or regions of the planet that May be swallowing huge amounts of the Gas. A one of Many suspects is peat lands. Bogs and bog forests absorb Large amounts of Carbon dioxide. Acid rain stimulates the growth of mosses and bog vegetation. Klinger believes this growth might have increased global absorption of the Gas Over the past 50 years. A peat lands Are very potent ecological forces a he said. A a there a no question that they play a major role in the Carbon at a glance Jordan size 37,737 Square Miles slightly larger than Indiana population 3,031,000 1990 estimate main languages arabic and English overview Jordan is made up of four main land regions the Jordan River Valley which runs from the sea of Galilee in the North to the dead sea the palestinian Hills to the West of the Valley in the occupied West Bank a Large plateau stretching eastward from the Valley and a desert which makes up the rest of the country. Farm products grown along the Jordan River and minerals Are major sources of income. The areas history goes Back to the founding of Jericho in 8,000 . And ruins from roman Arab and _ Christian conquerors can still be seen. Jordan became a British mandate after world War i and Independent in a 1946. It has been involved in several conflicts with Israel Over control of the West Bank its a fact the dead sea is a Salt Lake 1,296 feet below sea level making it the lowest spot on the Earth a questions a q. When they Are Strung with Holiday lights in the Winter. A a not unless the tree is brought inside in a pot and exposed to warm dry air and then suddenly taken Back outside into the cold or unless the lights Are hot enough to cause Burns says Jeannie ferns Worth a Horticulturist at the botanic Garden in Brooklyn . Light does affect the growth Cycle of Trees she said but chiefly in combination with temperature changes which Are closely related in nature. A a a Quot / a Ain the Winter the outdoor cold has More effect on a dormant deciduous tree than Light does. She said leafless Groves Hung with Small White lights As in some Public Parks stay dormant because there Are no leaves to absorb the Light. Light will not affect the Trees until they Are also exposed to the warmer temperatures of Spring. Evergreens will react somewhat to extra Light in Winter but they Are also More sensitive to temperature and their processes like photosynthesis proceed All year Long at a much lower rate than for deciduous Trees with very slow 1 Talcup of water and transpiration.
