Scientists have done experiments to show that there has been a rapid increase in global temperatures over the years. based on these experiments, which of these tables best shows the atmospheric carbon dioxide level from 1600 to 2000? year 1600 1700 1800 1900 2000 carbon dioxide level (in parts per million) 284 328 110 296 190 year 1600 1700 1800 1900 2000 carbon dioxide level (in parts per million) 110 190 284 296 328 year 1600 1700 1800 1900 2000 carbon dioxide level (in parts per million) 328 296 284 190 110 year 1600 1700 1800 1900 2000 carbon dioxide level (in parts per million) 296 190 328 110 284
