Lecture 2:

W:19.Earlier thisyear, British explorers Pen Huddle and his team tried three months to cross thefrozen Arctic ocean taking measurements and recording observations about theice.

M:While we have been believed that we would bein account of a good proportion of this older, thicker, technically multi-yearice that has been around for a few years and just get thicker and thicker. weactually find there wasn’t any multi-year ice at all.

W: Some observations and summering serviceover the past several years has shown less ice in the polar region. 20.But the recent measurements show the lost is morepronounced than the previous thought.

M:We are looking at roughly 80 percent loss ofice cover on the Arctic ocean in ten years, roughly ten years and 100 percentloss in nearly twenty years. Cambridge Scientist Peter Whitens who is measuringthe findings that in the summer season . 21.Butresearch management shows the lost of than previous thought. We are roughly looking at the percent ice cover forten years. roughly ten years about 100 percent invisible. The more youlose, the more you created during the summit The less forms in winter, thefollowing in summer. It comes down brain successes until it has gone.environmental treaty worldwide like fun. The artists say ice in the symptom.fast than expected. Actually, it has to translate into more urgency to dealwith climate changing problems and reduce emissions. Greenhouse emissions blamefor global warming needs to come out the by the change summit in December. wehave basically achieved there, to communicate the deal. that’s the minimum.

M:We has to do that incredibly. And that wehave to find the equipment .What the needs urgency The carbon we produce intothe atmosphere keeps the warming fire for 1000 years. 22.Sowe have to come back the rapidly now. Because it takes a long time to work itthrough into our response by the atmosphere. We cannot switch off globalwarming. We have to stop being good in the near future. We had to now. There isnot easy technological What is more easy to climate change. He and otherscientists said there are the two optional to replace the fasten fuels.Generally, energy with the global warming in nuclear power.
