1. How can geospatial information (remote sensing, GPS GIS) help humans to understand phenomena such as global warming or deforestation?

They provide us with accurate data that is needed to make adjustment on earth's surface.

Explanation:

The use of techniques like the Global positioning system, Geographic information system, and remote sensing is a tool that provides us with geospatial information and help us understand the laws of nature.  These all act as sensors and provides us information directly from the space with coordination to sun-synchronous and geostationary satellites. The use of technology like the lidar and radar also helps in understanding the global warming and deforestation patterns around the world.
