The entire ice mass of Greenland will disappear from the world map if temperatures rise by as little as 2C, with severe consequences for the rest of the world, a panel of scientists told Congress today. Greenland shed its largest chunk of ice in nearly half a century last week, and faces an even grimmer future, according to Richard Alley, a geosciences professor at Pennsylvania State University. "Sometime in the next decade we may pass that tipping point which would put us warmer than temperatures that Greenland can survive," Alley told a briefing in Congress, adding that a rise in the range of 2C to 7C would mean the obliteration of Greenland's ice sheet. The fall-out would be felt thousands of miles away from the Arctic, unleashing a global sea level rise of 23ft (7 metres), Alley warned. Low-lying cities such as New Orleans would vanish.Seems like a feeble way to deal with calamity in the future. Hope , that is. While hope is necessary , it isn't enough. What can one person do (besides curling up in bed in the fetal position? ) I walk to work. One can always drive less - take public transit - insulate one's house - turn the thermostat down . All important collectively. However, the most important - join or create a group of like minded people so that you have community support and can educate and encourage other people IN A MANNER THAT MOTIVATES THEM TO ACT. (The tone of the message should reflect the interests/ motivations of the group in front of you.) And second most important - pressure your government to take action and to change policy. Maybe equally important!
