Londonderry, N.H.: Today we celebrate Earth Day, but unfortunately, our Earth is in serious trouble. The Greenland ice sheet is melting at an accelerating rate due to the increase in global temperatures caused by carbon emissions blanketing the atmosphere and due to deforestation. The average temperature in the world is increasing by 3.2 degrees centigrade compared to the goal limit of 1.5 degrees centigrade to sustain a livable planet.
