Why are my white roses turning pink?

Why are my white roses turning pink? We have a large climbing white rose. Its very abundant and has bloomed white for years. This year its showing pink edges and even completely red roses. More importantly, can this be stopped and reversed?

Most white roses have a tinge of pink as they age. Certain environmental conditions (such as cool temperatures or other stress) can accentuate this phenomenon. If some roses are turning completely red, it's more likely to be a mutation. If that's the case, prune out the affected part of the rose so that it doesn't take over and become the main part of the plant.
