More than 40% of Antarctica’s ice shelves have shrunk since 1997 with almost half showing “no sign of recovery”, a study has found, linking the change to the climate breakdown.

Scientists at the University of Leeds have calculated that 67tn tonnes of ice was lost in the west while 59tn tonnes was added to the east between 1997 and 2021, resulting in a net loss of 7.5tn tonnes.

Warm water on the western side of Antarctica has been melting ice, whereas in the east, ice shelves have either stayed the same or grown as the water is colder there.

Is that supposed to mean "trillion"?

Is it tons of tonnes? If they put the whole number it would have helped

No numbers, just awkward analogies, but yes it's trillion:

If all the lost ice was piled on London, it would stand over 2 km tall - or 7.4 times the height of the Shard. If it were to cover Manhattan, it would stand at 61 km – or 137 Empire State Buildings placed on top of one another. 
- I think this from March is the research they reference
