Data can reveal truth of climate change

We live in a world where digital data is almost as pervasive and unnoticed as the air we breathe. We have become an integral part of the Internet of Things; our personal smart items that we carry with us are sensing the world around us and sharing it with other smart things in our environment including our TV, refrigerator, thermostat, car, bridges — the list is ever growing. The amount of data that is being gathered and exchanged is staggering and growing fast. A billion tweets every 72 hours is one example. Collectively, the amount of data in our digital universe — approximately 5 trillion gigabytes — is doubling every two years.
