The Northern Hemisphere is on track for this year to be the warmest since record-keeping started 127 years ago. Hemisphere-wide, temperatures for January through October averaged 1.3 degrees above the norm and could break the record for the warmest year, set in 2003. The warming trend could impact the melting of Arctic sea ice and worsen drought conditions throughout the United States. In Salt Lake City, Utah, the summer of 2007 was the warmest ever on record. The months of June, July and August averaged 0.7 degrees warmer than they did in 1994 — the previous record-breaking year. July was Salt Lake City's hottest-ever record; August was its second-hottest. In addition, spring 2007 in Salt Lake City was the third-warmest ever recorded. Last winter, normally the wettest time of year in the Southwest, was unusually dry. Los Angeles had its driest "water year" (measured from July to June) on record with 3.21 inches of rain. As for the coming winter, the recently updated U.S. forecast by the Climate Prediction Center calls for UNUSUAL warmth to persist across most of the nation — 4 percent warmer than the 30-year average — continuing a decade-long trend of warm winters. Drought could begin to develop across the southern Plains, which until now has had a very wet year, according to the latest forecasts. Texas is experiencing its fourth-wettest year on record. The only areas forecast to be wetter-than-average this winter are in the Pacific Northwest and the Ohio Valley.
