Southwest Climate Podcast: Scant Precipitation and Resilient Ridges

Tuesday, January 28, 2014

In the January Southwest Climate Podcast, CLIMAS climate scientists Zack Guido and Mike Crimmins discuss the scant precipitation in recent months across the West and the role of the "ridiculously resilient ridge" – a persistent area of high pressure parked off the West Coast – in steering storms away from the region.

CLIMAS Colloquium: Megadrought Risk - From the Globe Down to the Southwest

Friday, January 24, 2014

CLIMAS Colloquium Series - Speaker: Jonathan OverpeckIncreased drought risk is (and will be) arguably one of the most certain and troubling aspects of anthropogenic climate change for many parts of the world. At the same time, it is emerging in the scientific literature that state-of-the-art climate and Earth system models are not able to simulate the full range of drought, whether decade-scale droughts like seen recently in both the SW US, and Australia, or multidecadal “megadroughts” that eclipse droughts of the instrumental era in both duration and severity. Evidence for this assertion will be examined, particularly as it comes from the paleoclimatic record of several continents, in both semi-arid and wetter regions. The implications for decision-making will also be discussed, including the on-going operational use, in the United States, of no-regrets drought planning strategies that incorporate paleoclimatic data. Fortunately, because droughts will still occur for natural reasons as well as anthropogenic, increased drought preparedness is a clear “no-regrets” climate change adaptation strategy. (read more)

Regional Climate Summit for Municipal Leaders: Economic, Health, Water & Transportation Impacts

Thursday, November 14, 2013

Decision makers in southern Arizona face new challenges as climate variability and weather extremes increasingly affect the region. Our municipalities undertake planning activities and public investments that shape our economic prosperity, public health, and environment. Extreme events, warmer temperatures, and changes in precipitation will dramatically impact these efforts.   This half-day summit will explore the risks, potential costs, and proactive solutions necessary to combat and cope with climate change challenges affecting southern Arizona. Participants will learn from other municipal leaders and technical experts. The summit begins a dynamic regional dialogue to leverage ongoing and future efforts in cross-jurisdictional climate-related challenges. (read more)
