I think that we do. It's pollution, carbon dioxide, and other chemicals that are even more potent, but in smaller quantities, that cause this. Look, the world's temperature is going up, weather patterns are changing, storms are getting more violent and unpredictable.
The Earth is getting warmer, weather patterns are shifting, and storms are becoming more volatile - pollution, carbon dioxide, and other chemicals cause this.
