You would benfit greatly from using a hash (datatype), also known as a dictionary. For every line, take the line in, and add it to the element for that year. i.e.

$totals{$year_x}+=$yr_tot;

update Later on, you would use keys %totals to get all years and you can iterate through that via some loop (for,foreach,while...)
