Question
Is global warming real, only a theory or speculation?
✓

Answer

Global warming is real and has been with us for sometime, increasingly during the past two decades, but gradually for more than a hundred years. The reality of it is seen in direct temperature measurements and also in the melting of glaciers in low latitudes, permafrost decay in Alaska and the decrease in sea-ice cover in Arctic.
