If the pictures of the massive forest fires in Colorado, the widespread flooding in the southern states, the floods and droughts in California, the snow in the southern states, the melting ice in Antarctica aren’t convincing enough to demonstrate global warming; then here are some details about climate change. This June broke the records of 3,215 high-temperature readings across the United States. This report was followed by the warmest May on record in the Northern Hemisphere—the 327th consecutive month where the temperature of the Earth exceeded the average 20th-century average. The odds were about one in a million, a number much larger than the number of stars in the universe. Take a look at the third of summer sea ice that is gone,

(Good topic sentence.) In order to grasp the significance of our predicament, one needs to do just a little bit of math. In the past year, an easy and powerful bit mathematical analysis from a group of financial analysts has been spreading throughout environmental conferences. This document helps us understand our precarious position with three simple numbers. (This setup could be more concise.) The first important number is the less than two-degree increase in the global temperature. The background of this comes from the meeting of the world’s nations in Copenhagen in 2009 to discuss the global fight to slow down climate change. According to Sir Nicholas Stern of Britain, this meeting was the “most important gathering since the Second World War,” given what was at stake. However, the event turned out to fail spectacularly. Neither China nor the United States, responsible for forty percent of the global carbon emissions, were prepared to offer dramatic concessions. But, the only positive outcome of the meeting was a unanimous agreement with “the scientific view that the increase in global temperature should be below two degrees Celsius” to prevent further damage to our environment. (This paragraph wanders a bit from the discussion of the numbers to the discussion of the meeting. These two points would be stronger if they were
