Italy
Flames Engulf Sardinia Region
About 1,000 residents and tourists have been evacuated from areas of western Sardinia that were ravaged by wildfires over the weekend. No deaths or injuries have been reported according to Italian authorities. Since Saturday, at least 78 square miles (200 km sq) of land have gone up in flames. The cause of the fire is unclear. Wildfires are common in Sardinia’s dry Mediterranean environment in the summer, especially when winds blow on days where temperatures reach 104°F (40°C). Italy has registered almost 13,000 more wildfires than last year, mostly in the southern regions of Apulia, Calabria, and Sicily.
This map depicts the Sardinia region of Italy where wildfires have scorched at least 50,000 acres of land. Click on the map to learn more.

World
New Rainforest Vulnerability Index
A group of international scientists and researchers have created a new index to measure tropical rainforest vulnerability using satellite data. The index is called the tropical first vulnerability index (TFVI) and combines various measurements of forest ecological functions and services as well as spatial information to identify potential risks. Humid tropical rainforests are especially sensitive to climate change effects like higher temperatures, frequent droughts, extensive deforestation, and changes in land use and climate but are also a key component to them. By using TFVI, scientists hope to monitor and mitigate threats to rainforests before the change is irreversible.

Q: Spanning roughly 31,000 acres of wilderness, which U.S. national park was forged 1.7 billion years ago by a river cutting through its Precambrian metamorphic rock?
A: Black Canyon of the Gunnison
Located in western Colorado, Black Canyon of the Gunnison National Park was created in 1999, however the narrow canyons were carved out millions of years ago by the Gunnison River. The park was named for its steep metamorphic walls that are often shaded in the canyon that makes them appear black.
