1 . The sound that woke Damian Languell at 8:15 am was so loud that he assumed it came from inside his house. As he got up to investigate, he heard another sound, this one coming most definitely from outside. Looking out of his bedroom window, he spied a tree engulfed (淹没) in smoke about 500 yards away. A car was wrapped around the tree’s base, its engine on fire.

Grabbing buckets of water, Languell and his girlfriend ran to the crash site. The wreck looked worse up close. The car, a 1998 Buick, was split nearly in two, and the tree was where the driver’s seat ought to have been, as if planted there. No one should have survived this crash, and yet there was 16-year-old Quintin Thompson, his terrified face pressed against the driver’s side window, in visible pain. Languell tried putting out the fire with his buckets of water with no success. When the flames got into the front seats, he realized he had to get the boy out of there.

In an act that a police report described as showing “complete disregard for his own safety”, Languell opened the Buick’s back door and crawled in. Thompson was struggling to get free, Languell says. “That’s when I noticed how bad his legs were.” Using a pocketknife he’d had the foresight to bring with him, he sawed through Thompson’s seat belt.

Now that Thompson was free, Languell pulled him out a back window of the vehicle, then dragged the teen to safety before the entire car was engulfed in flames.

Although Thompson suffered multiple fractures (骨折) to his legs, spine, and face, a social media post described him as “looking great, smiling, and joking.” Languell thinks about that day often. “My heart goes out to Thompson. When you are that close to that level of hurt, you feel it so directly.”

3 . Population data for European mountain birds have been for the first time combined in a recent study, with worrying results: the abundances of mountain-specialist birds has declined by as much as 10% in the 2000s.

Ecological communities in mountain areas include species not found in any other habitats. These species are also very susceptible to climate change, as global warming is reducing their liveable habitats. In principle, species may relocate further up the mountains, but closer to the top their habitat inevitably shrinks.

According to the new article, the abundance of European mountain birds has in fact declined in line with climate change projections.

The recently released study examined the population trends of 44 bird species in the 2000s in the mountain and fell regions of Fennoscandia, Great Britain, the Alps and the Iberian Peninsula. A decline was seen in 14 of the observed species, while eight of them saw significant increase.

“On average, population decline among the species studied was 7% over the 13-year research period, making the situation of mountain birds distinctly worse compared to, for example, European forest birds, whose numbers did not change during the same period,” explains Aleksi Lehikoinen, an Academy of Finland research fellow at the Finnish Museum of Natural History Luomus (part of the University of Helsinki), who headed the study.

The situation is the direst for species that only inhabit mountain regions and are unable to live in other European environments. For these species, known as mountain specialists, the numbers dwindled by as much as 10% during the monitoring period.
