Introduction:

We read on books that glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is scrambling to keep pace but does the global warming reached us already in our city?

It has become clear that humans have caused most of the past century’s warming by releasing heat-trapping gases as we power our modern lives.

Global warming is the increase in the average temperature of the earth’s surface air ans oceans since the mid-20th century and its projected continuation. Global surface tempetarure increased during the last century. Increasing greenhouse gas concentrationresulting from human activity such as fossil fuel burning and defosrestation are responsible for for most of the observed temperature increase.

Explain how to do an smart irrigation: Unlike traditional irrigation controllers that operate on a preset programmed schedule and timers, smart irrigation controllers monitor weather, soil conditions, evaporation and plant water use to automatically adjust the watering schedule to actual conditions of the site.

For example, as outdoor temperatures increase or rainfall decreases, smart irrigation controllers consider on site-specific variables, such as soil type, sprinklers’ application rate, etc. to adjust the watering run times or schedules. There are several options for smart irrigation controllers.
