The White House has announced a new Tribal Climate Resilience Program and has dedicated nearly $10 million to help tribal communities prepare for and adapt to climate change impacts on their lands. The program will provide direct support through climate adaptation grants and will also offer funding for development of science-based tools for climate resilience planning and adaptive resource management. In addition, five tribal Climate Extension Support Liaisons will be placed in the Department of the Interior’s Climate Science Centers (CSCs), including the Southwest CSC.
The monsoon season started out with a bang in southeastern Arizona and forecasts over the next three months call for continued above-average precipitation, according to the latest CLIMAS Southwest Climate Outlook. June, however, was the third driest on record for Arizona, according to the NOAA State of the Climate, and storage in Lake Mead fell once again. A new podcast series from CLIMAS explores what a first-ever shortage declaration on the Colorado River would mean for the region. For a review of the state of the climate in 2013, see the link below to BAMS.
Climate only indirectly influences plant productivity by determining how large plants can grow and how long they can live, according to a recent study published in Nature. University of Arizona researchers found the size and age of plants, more than temperature and precipitation, control most of the variation in plant productivity. According to the authors, these results can improve our understanding of the plant-atmosphere feedbacks that control climate change and can be used to better predict the effects of global climate change.
