Dan Czizco

Dan Cziczo will speak about his work as an atmospheric scientist interested in the interrelationship of particulate matter and cloud formation. His research utilizes laboratory and field studies to elucidate how small particles interact with water vapor to form droplets and ice crystals which are important players in the Earth’s climate system. Experiments include using small cloud chambers in the laboratory to mimic atmospheric conditions that lead to cloud formation and observing clouds in situ from remote mountaintop sites or through the use of research aircraft.

Excessive Winter Deaths. Don't Expect Reductions From Global Warming

A presumed benefit of global warming is the assumption that warmer winter temperatures might decrease excessive winter deaths (EWDs) common in temperate climates. EWDs are defined as the difference between the number of deaths in a region during winter months (December – March) and the average of the proceeding fall and subsequent spring deaths. EWDs are attributable to a number of factors including higher incidences of cardio-respiratory and infectious diseases along with colder temperatures and icy conditions that can cause hypothermia and accidental falls.

After a Hard Winter, Scientists Explain "Where Has All the Warming Gone?"

After much of the U.S. experienced an unusually long and cold winter, many ask whether climate change is still happening.  There has, in fact, been little change in global mean annual temperature since the early 2000s leaving scientists struggling to figure out where the heat associated with continuing greenhouse gas emissions has gone.  In a recent paper…

South America Weather Forecast: Gastrointestinal Disease Likely

Climate scientists predict that climate change will lead to increased variability in precipitation over much of South America.  Research by Carlton et al (2013) on residents of northwestern rural Ecuador who rely on streams and rivers for their drinking water shows how those changes might impact water quality and associated rates of diarrhea, a water-related disease which leads to approximately 1 million deaths of young children worldwide each year.  The study further highlighted curious dynamics involving precipitation and water-borne disease.

Culture and Arctic Climate Change: A scoping workshop to explore integrative frameworks

This workshop is motivated by the appreciation that our knowledge of the human role in the Arctic system over millennia can be refined and greatly improved through better integration of Arctic archeology, ice
core and other re-constructions of climate parameters and studies of the contemporary Arctic environment. The two-day workshop will bring together researchers working across a range of disciplines in order to explore the complex relationship between the dynamic Arctic environment and long-term human cultural responses.

"Polluters Talk. We Walk." NGO's Make Themselves Heard at COP 19

“Polluters talk, we walk” was the chant two weeks ago, as thousands of climate change activists walked out of the 19thUnited Nations Council of Parties (COP 19) conference a day before negotiations were scheduled to end. A spokesman for Oxfam blamed negotiators for insufficient outcomes to limit global temperature rise to 2 degrees Celsius as outlined by the United Nations Intergovernmental Panel on Climate Change.
