2 The Nation has become Climate-Conscious… for Good Reason

Extremes are Happening at Public Gardens:

Extremes are Happening at Public Gardens Hurricane Sandy (2012) Several public gardens reported significant tree damage. Flood Damage: South Carolina Botanical Garden - Clemson , South Carolina (July 2013 ) Winter Snow Storm – ( Jan 29 – Feb 3 2014) Effected West Coast to the Northeast 3

Newly Released Climate Assessments:

Newly Released Climate Assessments IPCC Fifth Assessment Report (AR5) http:// www.ipcc.ch/report/ar5/index.shtml Released in four parts between Sept 2013 –Nov 2014. Most comprehensive assessment of scientific knowledge of climate change since AR4 (2007). Third National Climate Assessment http:// nca2014.globalchange.gov / Released May 2014 The authoritative and comprehensive report on climate change in the U.S. 4

NCA Key Message: U.S. Precipitation Change Average U.S. precipitation has increased since 1900, but some areas have had increases greater than the national average, and some areas have had decreases. More winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century.:

NCA Key Message: Heavy Downpours Increasing Heavy downpours are increasing nationally, especially over the last three to five decades. Largest increases are in the Midwest and Northeast. Increases in the frequency and intensity of extreme precipitation events are projected for all U.S. regions.:

Consider setting up a gauge at your public garden. By doing so you’ll engage your visitors in climate literacy and provide important precipitation data locally and to the country. Photo: Kristy Johnston

NCA Key Message: Recent U.S. Temperature Trends U.S. average temperature has increased by 1.3°F to 1.9°F since record keeping began in 1895; most of this increase has occurred since about 1970. The most recent decade was the nation’s warmest on record. Temperatures in the United States are expected to continue to rise. :

NCA Key Message: Lengthening Frost-free Season The length of the frost-free season (and the corresponding growing season) has been increasing nationally since the 1980s, with the largest increases occurring in the western United States, affecting ecosystems and agriculture. Across the United States, the growing season is projected to continue to lengthen.:

NCA Sectoral Key Messages:

NCA Sectoral Key Messages Water: Water quality and quantity (droughts and floods). Agriculture: Stresses due to weeds, diseases, and pests. Forests: Disease, pests, wildfire, carbon dioxide. Ecosystems Key Message: Extreme Events : Climate change, combined with other stressors, is overwhelming the capacity of ecosystems to buffer the impacts from extreme events like fires, floods, and storms . Key Message: Plants and Animals : Landscapes and seascapes are changing rapidly, and species, including many iconic species, may disappear from regions where they have been prevalent or become extinct, altering some regions so much that their mix of plant and animal life will become almost unrecognizable. Key Message: Seasonal Patterns : Timing of critical biological events, such as spring bud burst, emergence from overwintering, and the start of migrations, has shifted , leading to important impacts on species and habitats . 16

NCDC:

NCDC www.ncdc.noaa.gov / NCDC is the world's largest active archive of weather data. NCDC produces numerous climate publications and responds to data requests from all over the world. Photo: Henry Reges

NOAA’s Climate Portal:

NOAA ’ s Climate Portal www.climate.gov NOAA ’ s Climate Services Portal showcases a wide breath of climate information. With the click of a mouse the user has easy access to climate data and services, timely articles and information, education resources, and tools for engagement and decision-making.

Regional Climate Centers:

Regional Climate Centers Photo: Henry Reges NOAA ’ s Regional Climate Centers provide general and user-defined regional and local climate products and services, as well as regional and local expertise and assistance to a wide range of customers. www.wrcc.dri.edu / rcc.html

State Climate Offices:

Your best resource for looking at “ local climate details ” in your state. Most states have a state climate office which can provide custom climate data and information. www.stateclimate.org / State Climate Offices Photo: Henry Reges
