Renowned climate scientist, Dr. Jerry D. Mahlman, previously a resident of Longmont, CO, and recently of Sunrise Assisted Living in Buffalo Grove, IL, died peacefully on November 28, 2012. Jerry was born on February 21, 1940 in Crawford, NE. He received his undergraduate degree from Chadron State College in 1962 and his Ph.D. in atmospheric science from Colorado State University in 1967. He was married in 1962 to Janet Hilgenberg of Hot Springs, SD. Dr. Mahlman spent most of his career modeling how Earth's atmosphere responds to the steady buildup of greenhouse gases. From 1970 to 2000 he worked at the Geophysical Fluid Dynamics Laboratory of NOAA in Princeton, NJ, serving as Director from 1984-2000, and was a Professor in Atmospheric and Oceanic Sciences at Princeton University. His expertise was understanding the behavior of the stratosphere and troposphere, and over many years he occupied a central role in interpreting the global warming problem to both policymakers and the public all over the world. Among his many awards he received the U.S. Department of Commerce Gold Medal, the prestigious Carl-Gustaf Rossby Research Medal from the American Meteorological Society and the Presidential Distinguished Rank Award- the highest honor awarded to a federal employee. After retiring from GFDL, he was a senior researcher at the National Center for Atmospheric Research in Boulder, CO.

The World lost Jerry and his beloved wife, Janet, in the same year. Each of them will be missed. Before moving to Colorado, they were very important to the Lawrence Road Presbyterian Church. I understand that there is a brick for them in the new garden. They had been very active leading the Youth Group at the Church. Even after they stopped doing it full-time, Jerry played pick-up basketball with some of the younger boys. Once, he got hurt by an accidental kick, but he did not complain about it. Janet was an important member of the Church Book Club. Anyone who knew them, will always remember both of them.

Julie: My family and I are so sorry for your loss. I know how much you loved him. I had the pleasure to get to know both your parents when we lived together and I'll always cherish those memories. Especially the time we tried to keep your "surprise" birthday party a secret from you. They were a big part of making that happen. Sending you love and prayers. Take comfort that they are now together again and will watch and guide you from above. Love you.
