Regional effects of global warming vary in nature. Some are the result of a generalised global change, such as rising temperature, resulting in local effects, such as melting ice. In other cases, a change may be related to a change in a particular ocean current or weather system.
In general, white wines exhibit more acidity than red wines. Acidity gives wine its crispness on the palate.
