Environmental Impact
Immediately following Iraq’s invasion of Kuwait, predictions were made of an environmental disaster stemming from Iraqi threats to blow up captured Kuwaiti’ oil wells. Speculation ranging from a nuclear winter type scenario, to heavy acid rain and even short term immediate global warming were presented at the World Climate Conference in Geneva that November.
About 700 oil wells were set on fire by the retreating Iraqi army and the fires were not fully extinguished until November 6, 1991, eight months after the end of the war. The fires consumed an estimated 6 million barrels (950,000 m3) of oil daily.
Their immediate consequence was a dramatic decrease in air quality, causing respiratory problems for many Kuwaitis. The sabotage of the oil wells also impacted the desert environment, which has a limited natural cleansing ability. Unignited oil from the wells formed about 300 oil lakes that contaminated around 40 million tons of sand and earth. The mixture of desert sand with the unignited oil and soot formed layers of "tarcrete" which covered nearly five percent of the country. Cleaning efforts led by the Kuwait Institute for Scientific Research and the Arab Oil Co., who have tested a number of technologies including the use of petroleum-degrading bacteria, produced significant results. According to a 1992 study from Peter Hobbs and Lawrence Radke daily emissions of sulfur dioxide were 57% of that from electric utilities in the United States, emissions of carbon dioxide were 2% of global emissions and emissions of soot were 3400 metric tons per day.
Scenarios that predicted serious environmental impact on a global level did not happen, though regional and long-lasting impacts, as noted above, were serious. At the peak of the fires, the smoke absorbed 75 to 80% of the sun’s radiation. The particles rose as high as 20,000 feet (6,100 m), but were scavenged from the atmosphere relatively quickly.
Vegetation in most of the contaminated areas adjoining the oil lakes began recovering by 1995, but the dry climate has also partially solidified some of the lakes. Over time the oil has continued to sink into the sand, with as yet unknown consequences for Kuwait's small groundwater resources.

Famous quotes containing the word impact:
“Television does not dominate or insist, as movies do. It is not sensational, but taken for granted. Insistence would destroy it, for its message is so dire that it relies on being the background drone that counters silence. For most of us, it is something turned on and off as we would the light. It is a service, not a luxury or a thing of choice.”
—David Thomson, U.S. film historian. America in the Dark: The Impact of Hollywood Films on American Culture, ch. 8, William Morrow (1977)
