An article in the Syracuse Post-Standard summarized the results of a recently accepted study by Drs. Michael Notaro, Val Bennington, and Steve Vavrus on projected changes in lake-effect snow in the Great Lakes Basin, using dynamical downscaling.

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.

A new study published in Nature Climate Change calculates the combined velocities of future climate and land use change in the coterminous US. This work was led by Bryson CPEP fellow Alejandro Ordonez, with colleagues CCR Director Jack Williams and Volker Radeloff and Sebastian Martinuzzi in CALS/Forest Ecology & Wildlife. The study reports that overall, speeds of climate change are higher than land use change, with the upper Midwest and eastern Great Plains as an area of expected to experience high combined climate and land use change.

Dr. Michael Notaro was interviewed by middle school student, Juliana Castillo, in a summer journalism class from the Wisconsin Center for AcademicallyTalented Youth (WCATY) Summer Transitional Enrichment Program (STEP). The interview addressed the reality of climate change, role of greenhouse gases, impacts on Wisconsin's climate change on ecosystems and human health, and lake effect snow.
