The Drought of 2014: Record Hot, Record Dry
CNAP Observations, No. 2

(Click above image for full report)
CNAP explores the 2014 drought in the latest release of CNAP Observations. The reason for the current drought, comparison to previous droughts, the link between this drought and the wildfire forecast and the key role of heavy storms are examined in this publication.

The California Environmental Protection Agency has released an updated and expanded edition of its 2009 report examining 36 indicators of climate change and their effects on California. CNAP researchers contributed extensively to the indicators identified in this easy-to-digest report. Each indicator is described in terms of what it is showing and why it is important. Factors influencing the indicator are explored as well as the data characteristics that contribute to the indicator.


Assessment of Climate Change in the Southwest United States
NEW! Report now available in Spanish - please click here
CNAP researchers have been contributed to a landmark study investigating climate and its effects on the people and landscapes of the US Southwest. The results of this study have been compiled into a book (cover to the left) as one of nine regional technical inputs to the National Climate Assessment. The following chapters were authored by CNAP researchers:

California has marked its third-driest winter despite much-needed precipitation in March. The long-term marker of winter's precipitation is the April 1 snow survey. This year the survey found just 32% of the average water content (2014 is one of the lowest water-content years; recrods began in 1930). The most recent drought-monitor places 99.8% of the state of California in a drought with 23% of the state in the worst category of exceptional drought. 100% of the state of Nevada is in a drought with 8% in an exceptional drought. Several of California's state reservoirs are at below average levels. The two largest reservoirs are below historical average levels: Lake Shasta (62%) and Lake Oroville (66%).

Our Changing Climate 2012
Scoping meetings are in progress for the preparation of the next version of this report

(Click here for full report)
The summary of the Third Assessment comprehensive California Changing Climate report was released July 31, 2012. This summary highlights findings from 24 studies that focused on local and statewide vulnerabilities, considering opportunities for action to reduce impacts. These studies find California will continue to get hotter, drier and experience accelerated rising sea levels.

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.
