Climate Smart Societies   A surge in energy demand increased global carbon emission levels to a 7 year high in 2018 (BP, 2019). Global temperatures in 2018 were 0.83°C warmer than mean temperatures between 1951 and 1980, with the past 5 years representing the warmest years since records began (NASA, 2019). The economic impact of natural disasters rose to USD 160 billion in 2018, almost 15% above the inflation-adjusted average over the last 30 years (Low, 2019). Clearly, another landmark year for the continuous intensification of the effects and impact of anthropogenic climate change India is ranked sixth among the ten most affected countries in the world as per the Global Climate Risk Index 2016, and accounts for about seven per cent of the global Green House Gas (GHG) emissions. It is therefore a crucial actor when it comes to dealing with climate change related issues.

These are known as bits.  Decimal to binary conversion : Any decimal number can be converted into its equivalent binary number. For integers ,the conversion is obtained by continuous division by 2 and keeping track of the remainder, while for fractional parts, the conversion is affected by continuous multiplication by 2 and keeping track of the integers generated . Example: Convert (13) 10 an equivalent base-2 number  For Fractional number  Example: Convert (0.65625) 10  to an  equivalent base-2 number  Example: Express the 25.5 decimal numbers in the binary  from : Binary to Decimal : Any binary number can be converted into its equivalent decimal number using the weights assigned to each  bit position.
