Rising sea levels recorded due to melting glaciers can be considered an observable indication of global warming

Explanation:

The glaciers in the sea are melting due to global warming.This is occurring due to the increase in the global temperature. Year after year, higher temperatures are being recorded and this heat in turn is melting the Arctic glaciers thus adding on to the level of the oceans.

The increased temperature will also disrupt the fauna and floral life. All automobiles don't necessarily have to contribute to global warming. There exist eco-friendly automobiles as well.
