Conditions over the past month have once again been dry and warm in Arizona and New Mexico, according to the April Southwest Climate Outlook from CLIMAS. Temperatures have been 1 to 5 degrees F above average, and precipitation has been less than 70 percent of average in much of both states.
By the year 2100, surface temperatures will exceed those of the Holocene (the past about 11,300 years), according to new research published in Science.
Heat from cities can have far-reaching effects, disrupting circulation patterns and changing surface air temperatures thousands of miles away, according to a new study published in Nature Climate Change.
Drought conditions persist throughout almost all of Arizona and New Mexico, and if another dry winter emerges many of the regions’ reservoir volumes will continue to decline, posing serious water-supply challenges in several areas, according to the January Climate Outlook from CLIMAS.
Temperatures in the Southwest U.S. are predicted to increase, with the greatest warming (3.5-6.5 degrees F) in the summer season and a localized maximum in central Utah, according to a new technical report produced as part of a series of regional climate descriptions by the NOAA National Environmental Satellite, Data, and Information Service prepared as input for the U.S.
The contiguous U.S. experienced its warmest year on record last year, with the average annual temperature 3.2 degrees F above average and—at 55.3 degrees F—a full degree warmer than the previous record set in 1998, according to the annual State of the Climate report from NOAA.
The Southwest continued to experience above-average temperatures in October, with many cities, including Phoenix, Albuquerque and Reno, experiencing October temperatures among the top ten warmest on record, according to the latest State of the Climate report from NOAA.
Extreme summer temperatures, such as those in Texas and Oklahoma in 2011 and Moscow in 2010, were definitively the result of global warming, according to a new study by NASA scientists published in PNAS. The authors found that in the summer, colder-than-average temperatures now—in the most rec
The contiguous U.S. experienced its warmest July on the record, and July was the all-time warmest month, with temperatures 3.3 degrees F above average, according to the newest State of the Climate from NOAA.
The first half of the year has been the warmest for the U.S. since recordkeeping began in 1895, with temperatures 4.5 degrees F above average, according to the June State of the Climate from NOAA.
