I doubt it, if it's growing an inch a day that'd be 2 weeks top to bottom!
Environmental factors at the moment won't help, hot outside and running the A/C to cool the air inside will lead to it cracking as the cold/hot air mix at that point.
Some screen places offer a patch type remedy, but if it's over an inch already then I doubt anyone would want to touch it.
If it went whilst you were away you might patch it with epoxy glue (like Araldite) but no way would I do that now - nor to be honest would I head abroad in it as I wouldn't want the hassle if it went. Would your euro breakdown even cover it as a pre-existing condition?
