1) I think that scientists are careful when measuring the Arctic sea ice at the same time every single year is if they don’t record the data at the same exact date every year, let’s say they make a graph with annual measurements at the same day every year all the records since the 80’s to now well then the graph would be wrong. The scientists have to be consistent to see, since last year what happened and compare it with the data of years previous. If the data records were all collected on differing dates every year then how would the scientists see if one year the melting of the Arctic ice is getting worse or is the melting slowly getting better? 2) Scientist view climate change with more urgency now than they did in 2007 because before scientist and even the most sophisticated computers thought that the sea ice “would not disappear before the middle of this century if then”. Meaning that in the middle of the 21st century the sea ice in the Arctic would disappear but even then they weren’t sure but now scientists think that the summer ice in the Arctic could disappear as soon as 2020. Another factor scientist view climate change with urgency is because the U.S has not responded to the change of limiting green-house gasses. This is a big deal because the U.S is the second most carbon emitting county that dishes out 5,610,000,000 metric tons of carbon. 3) Some changes that scientists fear may happen worldwide because of climate change is that because the ice is melting there is less summer ice cover which means that the dark waters will trap the sun’s heat and will melt the ice which will contribute to the melting of the ice sheets in Greenland. The sea level will rise as the ice melts which is bad-bad news for people living in coastal communities all over the world at risk. Let me give the facts New York City has 520 miles of...
