NASA, Harvard scientists study wine harvest dates in cool-weather countries
Global warming is changing centuries-old climate patterns that are crucial for wine production in cool-weather regions, a new study from NASA and Harvard concludes. After analyzing climate records and grape harvesting dates from 1600 to 2007, the scientists found that harvests started happening much earlier during the second half of the 20th century.
These shifts were caused by changes in the connection between climate and harvest timing. Between 1600 and 1980, earlier harvests were linked to years with warmer and drier conditions during spring and summer. After that, global warming caused earliers harvests in years without droughts.

Swiss study shows widespread effect of air pollution
FRISCO — Scientists in Switzerland say they’ve measured a startling decline in plant diversity linked with high human atmospheric nitrogen emissions. Their study, published in the journal Royal Society Open Science, shows the loss in traditionally measured plant species richness at 5 percent, while the loss in phylogenetic plant diversity due to human-induced nitrogen deposition is 19 percent.

Research documents rapid upward shift of plant communities

FRISCO — Swiss researchers taking a close look at the effect of global warming say that plants, birds and butterflies sprinted uphill by anywhere from eight to 42 meters between 2003 and 2010 — a significant shift in a very short time, according to the study published
Conservationists call for restrictions on winter recreation in core habitat areas
By Summit Voice
SUMMIT COUNTY — In research that might of interest to Summit County leaders as they mull over recreation and development plans, Swiss scientists say they have linked burgeoning winter recreation activities in the Alps with a severe decline of wood grouse populations.
The study, published in the journal IBIS, shows how the growth of human recreation may be a key factor in the rapidly declining population of these iconic alpine birds.
The wood grouse, sometimes called the Capercaillie (Tetrao urogallus), is the largest member of the grouse family and is renowned for its mating display. It is most commonly found in the alpine regions of Germany and Switzerland.
