A growing number of studies have highlighted the consequences climate change on agriculture, including impacts extremes such as drought, heat waves and frost. The aim this study was to assess influence temperature various phenological events grapevine varieties in Southwest Switzerland (Leytron, Canton Valais). We aimed capture occurrence extreme specific years at different phases rank based th...

[1] The winters of 2009–2010 and 2010–2011 brought frigid temperatures to parts of Europe, Russia, and the U.S. We analyzed regional and Northern Hemispheric (NH) daily temperature extremes for these two consecutive winters in the historical context of the past 63 years. While some parts clear ly experienced very cold temperatures, the NH was not anomalously cold. Extreme warm events were much ...

During the period 1979–1992, on average nearly 400 people each year were killed in the United States by excessive heat (NOAA 1995; Kilbourne 1997). In fact, in this period over the United States, excessive heat accounted for more reported deaths annually than hurricanes, floods, tornadoes, and lightning combined (NOAA 1995). Furthermore, agriculture products such as wheat, rice, corn and maize ...

[1] Observations averaged over the U.S. for the second half of the 20th century have shown a decrease of frost days, an increase in growing season length, an increase in the number of warm nights, and an increase in heat wave intensity. For the first three, a nine member multi-model ensemble shows similar changes over the U.S. in 20th century experiments that combine anthropogenic and natural f...
