Global Warming 101

Wild Chronicles host Boyd Matson joins former National Geographic Explorer-in-Residence Will Steger on Canada's Baffin Island to take part in an innovative education program -- Global Warming 101. Traversing the Arctic expanse by dogsled and reporting observations via satellite, the team hopes the expedition will give a face to climate change and show how people, not just the landscape, are being affected by melting ice and rising temperatures.

@damienfeb01 Not this time

great video. easily 5/5

@Peggycass Perhaps you'd like to do another little experiment, as well. The same one I'm going to do. 2 plants of the same kind in separate containers ( cut off 2 liter coke bottles). One gets CO2 from dry ice, once a week, the othere one doesn't. I'd be interested in seeing if we both get the same results.

[buisyman]

@TomHarrisICSC Big deal. A "consesus of scientists" once believed that the earth was flat, too, and burned anyone who argued with them.

[Peggycass]

@damienfeb01 Yes, people go on and on about the Polar Bear. The polar Bear would kill those people in as second. i can do without that.

[Peggycass]

@ElmntNinja Tell me what's going to happen when they do melt? And how quickly? Things like that take--Thousands, if not millions of years.

[Peggycass]

@buisyman i will try that experiment, then I'll let you know the results. i know it won't overflow. i'll have to see if the level goes down, thanks

[buisyman]

@Peggycass Why don't you try that little experiment, then? See what happens. When water freezes, it expands, and when it melts, it contracts, so you'll end up with a lower level than when the ice was in the glass.

[Peggycass]

@buisyman a lot of ice could melt, it won't flood the Earth. its not possible. like a glass of ice water. you have a glass ofv ice cubes and water--what happens when all the ice in the glass melts, does it OVERFLOW, OF course not. The same principle. Ice floating in the water melts, it simply displaces itself.

@MrOTLChamp and Al gore needs to go at the head of the line.

Everyone that believes that CO2 is catastrophic changes to our climate needs to have their head examined.
