Mystery Around Dead Hikers
Authorities have lifted a hazmat warning from the area of Mariposa County, California, near where a local family and their dog were found dead on Tuesday on a remote hiking trail. The family was found dead in the Sierra National Forest with no signs of trauma after being reported missing on Monday evening. The area was declared a hazmat site due to concerns that the family was killed by toxic gases from inactive mines in the area, but that warning was lifted following negative tests for carbon monoxide and other poisonous gases. Investigators are now turning to the possibility that the family ingested toxins from algae blooms in local waterways.

Bangladesh
Deadliest Year for Rohingya at Sea
A new report by the United Nations Refugees Agency (UNHCR), Left Adrift at Sea: Dangerous Journeys of Refugees Across the Bay of Bengal and the Andaman Sea, reveals that 2020 was the deadliest year on record for Rohingya refugees journeying from refugee camps in Bangladesh to Southeast Asia. For over ten years, Rohingya residents have been seeking refuge in mainly Malaysia or Indonesia after being denied basic human rights back in Myanmar. In 2020, 218 of 2,413 known refugees died or went missing at sea, surpassing 2015 as the deadliest year. This makes the journey eight times more deadly than it was in 2019, and more deadly for women and children. The UNHCR cites tightening border restrictions as a result of COVID-19 as a reason more refugees were stranded at sea.

Greenland
Rain At Summit of Greenland
For the first time ever, scientists have recorded rainfall at the peak of Greenland’s ice sheet. The precipitation was so unexpected that there were no tools to measure it. According to the National Snow and Ice Data Center, temperatures are usually well below freezing on Greenland’s peak, sitting about 10,600 ft (3,200 m) high, however this was the third time in history that scientists recorded temperatures above freezing. In May, researchers showed Greenland’s ice sheet loss had reached a tipping point, where accelerated melting would become inevitable without halting an increasingly warming planet.

Q: At 2,900 miles (4,700 km) long and an official deepest point reading of 722 feet (220 m) which river is the world’s deepest?
A: The Congo River
When we say the official deepest point reading for the Congo, that’s still probably not its true deepest point, which scientists haven’t yet discovered, but is estimated to be somewhere around 750 feet (228 m). The Congo is actually the second-largest river in the world for outflow into the ocean, after the Amazon. But unlike other huge rivers, instead of seeing its end at the ocean with a silty delta, the Congo’s powerful currents carved out a deep and narrow underwater canyon, which is where its still-unknown deepest point lies.
