WASHINGTON, June 10—  The rise in carbon dioxide and other gases in the earth's atmosphere will have an earlier and more pronounced impact on global temperature and climate than previously expected, according to evidence presented to a Senate subcommittee today.

Scientists and senators at a hearing by the Environmental Pollution Subcommittee agreed that the dangers of manmade changes in the atmosphere had moved from hypothesis to imminent reality and must be addressed quickly.

They said the rise in temperatures was expected to cause profound climatic changes and raise sea levels substantially.

Witnesses at the hearing also testified that the ozone layer of the upper atmosphere, which protects the earth from the sun's ultraviolet light, is being rapidly depleted by manmade gases, and the increased ultraviolet radiation would result in a rise in skin cancer cases and other ecological damage.

Dr. James E. Hansen of the Goddard Space Flight Center's Institute for Space Studies said research by his institute showed that because of the ''greenhouse effect'' that results when gases prevent heat from escaping the earth's atmosphere, global temperatures would rise early in the next century to ''well above any level experienced in the past 100,000 years.'' Steeper Rise in Next Century

Average global temperatures would rise by one-half a degree to one degree Fahrenheit from 1990 to 2000 if current trends are unchanged, according to Dr. Hansen's findings. Dr. Hansen said the global temperature would rise by another 2 to 4 degrees in the following decade.

how'd that all work out climate deniers????
