The amount of heat-trapping carbon dioxide in the atmosphere hit a record high in May. That's because humanity kept emitting a prodigious amount of carbon, even through the worst pandemic in a century. But if civilization does begin to significantly cut emissions, global temperatures won't promptly start going down, like flipping a climate switch.
Silver, bug-eyed extraterrestrials zooming across the cosmos in bullet-speed spaceships. Green, oval-faced creatures hiding out in a secret fortress at Nevada’s Area 51 base. Cartoonish, throaty-voiced relatives of Marvin the Martian who don armor and Spartan-style helmets.
Despite the pandemic, NASA is on track to launch its Mars rover, Perseverance, this July from Cape Canaveral, Florida. Its central mission will be to search for evidence of previous life on Mars.
Tourists spend thousands of dollars to explore and enjoy Guatemala's lush and thriving rain forests. It's hard to believe that the landscape was different, but according to new research by climate scientists at the University of Nevada Las Vegas (United States), those places were probably very different less than 9,000 years ago, which is a “blink of an eye. eyes ”from the point of view of geological standards.
The 6.5-magnitude Tonopah earthquake was felt by many here in southern Nevada. It’s now raising questions if a similar-sized quake could rock the valley anytime soon.
She is sparkling. Determined. Brilliant. Arya Udry is 32 years old. This native Valaisanne, whose mother lives in Hérémence and who grew up between Brittany and neighboring France, is now a professor of geology and planetology at the University of Nevada, in Las Vegas. A dazzling journey for the one who, while crawling on the mountains of Valais, dreamed of being an astronaut. "To realize this dream, you had to either become a scientist or an airplane pilot."
Despite their microscopic size and simplistic cells, bacteria are some of the hardiest life forms around. In recent years, scientists have uncovered these stalwart microbes in environments as extreme as the searing hot springs in Yellowstone National Park and the acidic, metal-rich waters that drain out of mines.
IN 2013, SCIENTISTS were stunned to find microbes thriving deep inside volcanic rocks beneath the seafloor off the Pacific Northwest, buried under more than 870 feet of sediment. The rocks were on the flank of the volcanic rift where they were born, and they were still young and hot enough to drive intense chemical reactions with the seawater, from which the microbes derived their energy.
It's hard to believe the landscape ever looked any different. But according to new research by 51ԹϺ climate scientists, the locations where those jungles exist today likely looked very different less than 9,000 years ago -- a blink of an eye by geologic standards.

Arizona’s Department of Environmental Quality is allowing a uranium mine operator to spray water laced with uranium and arsenic on the ground to keep dust down on its site, but it is considering the status of the mine’s permit.
Nevada, because of its rich landscape and diverse history, is often regarded as a playground for geologists and paleontologists around the world.
