LATEST PUBLICATIONS

California Heat Waves
CNAP and partners from the National Weather Service (NWS), Climate Education Partners, the Southwest Climate Science Center and the Center for Western Weather and Water Extremes have compiled a 2-page summary describing heat waves in California. This summary explores the increase of more humid heat waves in California, especially along the coast and with warmer evening temperatures. The dangerous link between heat waves and human health is also examined. Trends towards more heat waves in recent decades and what we may see in a warming climate are discussed.

Drought in Southern California
CNAP and partners from NIDIS (National Integrated Drought Information System), the Southwest Climate Science Center and the California Department of Water Resources have compiled a 2-page summary exploring drought in southern California. The last four years of drought conditions, links to climate change, California's year-to-year precipitation variability and dependence on large storms, and southern California's water supply are featured in this summay.

California Precipitation
CNAP and partners from CW3E, the Southwest Climate Science Center and the California Department of Water Resources have compiled a 2-page summary exploring features of California's precipitation. The focus of this summary is the seasonality and variability of precipitation in the state, with an emphasis on the link between large storms and the seasonal total precipitation.

2015 Southwest Climate Summit

Bridging the Gap -- from science to management action in climate adaptation
2-3 November 2015
A 2-day summit in Sacramento will move "Climate-Smart Conservation" forward by bringing together managers and scientists from across the Southwest.

The latest drought monitor shows dought conditions continue to be extreme to exceptional over 94% of California and 87% of Nevada. The total precipitation over the last three years is at or below 70% of normal over much of California with some areas reporting less than half the normal precipitation. 2014-15 is not going to be the driest year for the northern Sierra 8-station index but does rank below normal and between the two most recent dry years (2012-13 and 2013-14). It has also been warm with maximum and minimum annual (May 2014 - May 2015) temperatures statewide the warmest recorded (since 1895) over the extreme west and near record warmest for much of the west. The snowpack has dwindled with little left to contribute to runoff or streamflow. From the May bulletin all water conditions (snowpack, precipitation, runoff and reservoir storage) are below normal for all years 2012-2015. Sea surface temperatures over the tropical Pacific, especially to the east, continue to be warm and an El Nino advisory has been issued with the likelihood of an El Nino event at 80-90% for 2015. There is quite a bit of spread amongst the models so it is uncertain how strong this event will be. The NOAA 3-month outlook shows probability of warm conditions persisting across the west through August.

CNAP Welcomes!
SIO Center for Climate Change Impacts and Adaptation
CNAP welcomes the opportunity to work with the Center for Climate Change Impacts and Adaptation at the Scripps Institution of Oceanography, a newly created center made possible by a generous contribution from Richard and Carol Dean Hertzberg. The new center will provide science-based strategies for adapting to climate change. Please read more by clicking here.

Happy Isles (Merced River) Webcam
USGS has opened a Happy Isles gage house in Yosemite Valley. CNAP researchers Mike Dettinger and Dan Cayan fought diligently for this new site. The site features a webcam showing the station and the merced River as it enters Yosemite Valley. The old gage house (circa 1915) can be seen in the background on daytime images.
