Search word and delete only the word and the line using Sed command

Hi All,
Struck with this, please help. Want to search for ~ and delete it as well as to append the entire line to the above line.
For Ex:
1111 xxxx date Sandy area is
~around this area.
3222 xxx date There seems to
~left side of map, the colours are accurate (showing green areas) Even if I
~zoom in, the green parks,
xxx 3258 date The dammed up
~away, the "other" body of water varies
~black Natural gas leaching.

IT MUST LOOK LIKE:
1111 xxxx date Sandy area is around this area.
3222 xxx date There seems to left side of map, the colours are accurate (showing green areas) Even if I zoom in, the green parks,
xxx 3258 date The dammed up away, the "other" body of water varies black Natural gas leaching.

This doesn't look like homework, so if it is, well done for obscuring it

sed ':a;N;$!ba;s/\n/ /g' file.txt

Hi,

acid_kewpie's example doesn't work on my side, this does:

Code:

sed '/^~/!{:tag;N;s/\n~//;b tag}' infile

Hope this helps.

Odd, fine for me. Maybe some whitespace issues aside.

Thanks to both of you.

"acid_kewpie" code doesn't work for me also and, "druuna" does.
