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.

Too much acidity will make the wine seem harsh or bitter; too little and the wine will seem flabby and dull.
