PARAGRAPH AHERE IS WHAT GLOBAL WARMING COULD DO IN A FEW YEARS

51. Paragraph A

Here is what global warming could do in a few years: in Dallas, a doubled level of carbon dioxide would

increase the number of days a year with temperatures above 100 degrees from nineteen to seventy-eight. On

sixty-eight days, as opposed to the current four, the temperature wouldn’t fall below 80 degrees at night. One

hundred and sixty-two days a year, the temperature would top 90 degrees.
