Global Change Conference Arizonans have just experienced the warmest March and April on record, with May temperatures continuing the trend.
Meteorologists blame it on a persistent ridge of high pressure.
Some people believe it may be a preview of the greenhouse effect and global warming. It will bring together scientific experts and policy decision makers to link scientific evidence of global change with the political and social dilemmas of enacting and implementing a corrective course of action. The science panel, chaired by Dr. Malcolm Hughes, Professor of Dendrochronology and Director of the Laboratory of Tree-Ring Research at the University of Arizona, will compare current climate conditions with what might be expected given the normal variation of climate change. Computer models are used to predict outcomes from increased atmospheric CO but only operate on a global scale. Scientific research will be crucial for determining the existence and extent of the greenhouse effect as well as predicting the outcomes of suggested solutions.
