Our Changing Climate 2012 Vulnerability & Adaptation to the Increasing Risks from Climate Change in California

A common-sense climate index: is climate changing noticeably?

We propose an index of climate change based on practical climate indicators such as heating degree days and the frequency of intense precipitation. We find that in most regions the index is positive, the sense predicted to accompany global warming. In a few regions, especially in Asia and western North America, the index indicates that climate change should be apparent already, but in most plac...

How Is Pacific Northwest Climate Changing?

 Increasing temperatures. The Pacific Northwest warmed about +1.3°F between 1895 and 2011, with statistically-significant warming occurring in all seasons except for spring. [A][1][2] This trend is robust: similar 20 th century trends are obtained using different analytical approaches. [3] All but five of the years from 1980 to 2011 were warmer than the 1901-1960 average (Figure 2-1, Table 2-1...

Changing Climate, Changing Watersheds

This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. These images are freely avail...
