Beijing on Friday upgraded its warning for hot weather to "red" - the highest in a color-coded alert system - with many parts of the Chinese capital roasting in temperatures of up to 40 degrees Celsius (104 Fahrenheit).

 

The official temperature for the capital, which is measured from its southern suburbs observatory, hit 40C just after 1:30 p.m. (0530 GMT) on Friday, according to the Beijing Municipal Meteorological Observatory.

 

"This is the first time since the establishment of the observatory that there has been a high temperature of more than 40C for two consecutive days," Zhang Yingxin, chief forecaster of the Municipal Meteorological Observatory, said at a press briefing. The observatory was founded in 1951.

 

On Thursday, the maximum temperature in the city of nearly 22 million people breached 41C and shattered the record for the hottest day in June.

 

A weather station in its southern suburbs, considered to be Beijing's main gauge, recorded 41.1C in the afternoon. The previous June high was logged on June 10, 1961, when the mercury hit 40.6C.

 

The daily maximum logged on Thursday was the city's second-highest in history, just below the 41.9C recorded by Beijing on July 24, 1999.

 

China has a four-tier weather warning system, with red the most severe, followed by orange, yellow and blue. A red alert indicates the temperature is set to rise above 40C within 24 hours.

 

The China Meteorological Administration said on Thursday it expected high temperatures to persist across much of the country's north for the next eight to ten days.

 

High temperature monitoring and warnings would continue on a rolling basis in places including Beijing, Tianjin, Hebei, Shandong, Henan and Inner Mongolia, it added.

 

In Tianjin, a northern Chinese port city with a population of over 13 million, Thursday's temperature reached 41.2C, smashing local records.

 

Local authorities on Friday warned the extended period of high temperatures could have health impacts, including an increased risk of stroke, and advised people to drink at least 1.5 liters of water daily and limit their time outdoors.

A deep-diving robot that chiseled into the rocky Pacific seabed at a spot where two of the immense plates comprising Earth's outer shell meet has unearthed a previously unknown realm of animal life thriving underground near hydrothermal vents.

Giant tubeworms - the world's heftiest worms - and other marine invertebrates such as snails and bristle worms were found using the remotely operated underwater vehicle SuBastian. They were living inside cavities within the Earth's crust at an ocean-floor site where the Pacific is 1.56 miles (2,515 meters) deep. All the species were previously known to have lived near such vents, but never underground, Reuters reported.

"We discovered vent animal life in the cavities of the ocean's crust. We now know that the unique hydrothermal vent ecosystem extends into the ocean's crust," said marine biologist Sabine Gollner of the Royal Netherlands Institute for Sea Research, one of the leaders of the study published this week in the journal Nature Communications.

"To our knowledge, it is the first time that animal life has been discovered in the ocean crust," Gollner added.

The exploration was conducted at the East Pacific Rise, a volcanically active ridge on the floor of the southeastern Pacific, running approximately parallel to South America's west coast. Earth's rigid outer part is divided into colossal plates that move gradually over time in a process called plate tectonics. The East Pacific Rise is located where two such plates are gradually spreading apart.

This area contains many hydrothermal vents, fissures in the seafloor situated where seawater and magma beneath the Earth's crust come together. Magma refers to molten rock that is underground, while lava refers to molten rock that reaches the surface, including the seafloor. New seafloor forms in places where magma is forced upward toward the surface at a mid-ocean ridge and cools to form volcanic rock.

The hydrothermal vents spew into the cold sea the super-heated and chemical-rich water that nourishes microorganisms.

"The warm venting fluids are rich in energy - for example, sulfide - that can be used by microbes, which form the basis of the food-chain," Gollner said.

Life flourishes around the vents - including giant tubeworms reaching lengths of 10 feet (3 meters), mussels, crabs, shrimp, fish and other organisms beautifully adapted to this extreme environment. The giant tubeworms do not eat as other animals do. Instead, bacteria residing in their body in a sack-like organ turn sulfur from the water into energy for the animal.

The researchers deployed SuBastian from the Schmidt Ocean Institute research vessel Falkortoo to the vent site deep below. The robot was equipped with arms that wielded a chisel that the researchers used to dig into the crust and uncover warm and fluid-filled cavities where the tubeworms, bristle worms and snails were spotted.

"We used a chisel to break the rock. We dug about 20 cm (8 inches). The lava plates were about 10 cm (4 inches) thick. The cavities below the lava plates were about 10 cm in height," Gollner said.

Larvae from these animals may invade these subseafloor habitats, the researchers said, in an example of connectivity between the seafloor and underground ecosystems.

"It changed our view on connectedness in the ocean," Gollner said of discovering the subsurface lair.
