The research of Drs. Michael Notaro, Steve Vavrus, and Yafang Zhong on the mechanism for the observed rapid warming of the Laurentian Great Lakes, as presented at the American Geophysical Union Meeting in December 2014, was summarized by a radio piece from the German Public Radio science program, Forschung Aktuell.

Weatherwise magazine featured an article on Wisconsin weather by our own Ed Hopkins, assistant Wisconsin State Climatologist at UW-Madison and co-author H. Michael Mogil, consulting meteorologist, in its Nov/Dec issue, saying "The Weather and Climate of Wisconsin: It's More Than Frozen Tundra."

Zhengyu Liu and Feng He are co-authors on a recent paper in Science (Dec. 5th) examining hydrological changes across the North and East Africa during the last deglaciation (about 20,000 to 10,000 years ago). They compared their simulation in state of art climate models with proxy observations and suggest that humid climate started across the Northern and Eastern Africa coherently in spite very different insolation regimes. This coherent change is caused by a systematic climate response across the northern and eastern North Africa in response to an increase of atmospheric CO2 and the meltwater forced response of Atlantic thermohaline circulation. This work has important implications for our prediction of future hydroclimate change across Africa.

Prof. Zhengyu Liu is the lead author of a recent paper in Nature (Nov. 27th) on the modeling and mechanisms of the evolution of El Nino over the past 21000 years. In collaboration with an international research group of experts, Professor Liu found that El Nino has intensified in the last 6000 years. They further found that El Nino changed in response to different forcing mechanisms in different periods. However, the paleoclimatic data currently available are too sparse to confirm other features of the El Nino change. Their work presents a major benchmark of past El Nino evolution study and has important implications to our prediction of El Nino in the future.

A new report is available from the Forest Service, "Forest ecosystem vulnerability assessment and synthesis for northern Wisconsin and western Upper Michigan: A report from the Northwoods Climate Change Response Framework." The lead author is Dr. Maria Janowiak, a scientist in Climate Change Adaptation and Carbon Management in the Northern Institute of Applied Climate Science. Dr. Michael Notaro, CCR associate director, served as an author on the report.

Ray Steventon, one of CCR's founding members, passed away on September 15, 2014. Ray Steventon joined CCR in 1964, within a year of it’s founding by Prof. Reid Bryson. CCR’s early years were notable for a strong emphasis on field research and technical measurements of aspects of earth’s climate – in the state, nation, and world. Ray’s technical expertise was crucial to the early success of these CCR field research projects. Ray retired from the University in 1989, after 25 years of service to CCR and the University. Ray’s contributions to the early and continuing success of CCR, now having passed its 50th year as a UW-Madison research center, are a tribute to his skill and his devotion to the University, and to his team spirit – always helping, always encouraging, always contributing, always gaining satisfaction in seeing others accomplish their goals.

An international research team, including CCR scientist Feng He and professor Zhengyu Liu, published new results in Science exploring the response of Greenland temperature to climate forcing during the last deglaciation. Using independent reconstructions from three ice cores and simulations with a IPCC-type coupled global climate model, the research team found that the Greenland temperatures 12,000 years ago during the Younger Dryas period near the end of the ice age was almost 5 oC warmer than the last glacial maximum as a result of increased carbon dioxide forcing and summer insolation.
