UN Climate Chief: Two Years Left to Avert Climate Catastrophe

Image
Simon Stiell, the UN climate chief, delivered a poignant address titled "Two Years to Save the World," warning that humanity has only a two-year window to prevent a climate catastrophe. Stiell urged nations to urgently enhance their climate plans, known as nationally determined contributions (NDCs), as outlined in the Paris Agreement. Despite the Intergovernmental Panel on Climate Change's (IPCC) call for global greenhouse gas emissions to peak before 2025 and decrease by 43% by 2030 to limit warming to 1.5°C, current NDCs are insufficient in achieving this goal. Speaking at Chatham House in London, Stiell stressed the imperative for stronger climate plans, emphasizing that existing NDCs will barely make a dent in emissions reduction by 2030. He emphasized the significance of a new generation of national climate plans to curb greenhouse gas emissions effectively. Stiell highlighted the crucial role of a new climate finance agreement at the upcoming UN Climate Conference (...

White House Directs NASA to Develop New Time Zone for the Moon

NASA Discloses Proximity of 100-Foot Asteroid Approaching Earth Today

Following the close passage of two 100-foot asteroids near Earth yesterday, another asteroid is poised to approach our planet today, with NASA closely monitoring its trajectory. Asteroids, remnants from the early formation of the solar system, vary in size and are predominantly found in the asteroid belt. However, factors like gravitational interactions with nearby planets can dislodge some asteroids from this belt. Due to the potential for significant destruction, space agencies worldwide, including NASA, continuously track these celestial objects. NASA employs a network of space- and Earth-based telescopes and satellites to monitor asteroids around the clock, sharing their findings regularly. Each day sees several asteroid flybys, some of which come remarkably close to Earth. Currently under scrutiny is Asteroid 2024 FL3, measuring 100 feet in diameter, with NASA providing details on its proximity to our planet. According to NASA's data, Asteroid FL3 will approach within approxim...

A study suggests that boulders propelled from NASA's DART mission might collide with Mars.

A recent study suggests that NASA's asteroid-deflection mission, DART (Double Asteroid Redirection Test), may have inadvertently launched numerous boulders on a potential collision course with Mars. In 2022, NASA conducted the DART mission, intentionally crashing a spacecraft into an asteroid named Dimorphos to alter its orbit, along with the trajectory of its larger counterpart, Didymos. The objective was to test methods for diverting potentially hazardous near-Earth asteroids, akin to those responsible for the extinction of nonavian dinosaurs. Initial assessments deemed DART a remarkable success; it successfully shifted Dimorphos' orbit by 32 minutes and altered its shape significantly. However, an unforeseen outcome emerged: the collision propelled a swarm of 37 boulders, some measuring up to 22 feet (6.7 meters), into space. Andy Rivkin, an astronomer at the Johns Hopkins Applied Physics Laboratory and a member of the DART team, expressed surprise at the quantity and size o...

Scientists Uncover Vast Ocean 700 Kilometers Beneath Earth's Crust, Holding More Water Than All Surface Oceans Combined

Researchers at Northwestern University in Evanston, Illinois have made a groundbreaking discovery: a vast reservoir of water lying deep beneath the Earth's surface, approximately 700 kilometers below us. This hidden underground water source was uncovered during investigations into the origins of Earth's water. The findings were published in a 2014 study titled "Dehydration melting at the top of the lower mantle," where scientists detailed the identification of this colossal oceanic body hidden within the Earth's mantle. The oceanic reservoir is encased within a type of blue rock called ringwoodite, located deep within the mantle, which is the layer of hot rock between the Earth's surface and its core. The sheer size of this reservoir has led to speculation that Earth's oceans might have gradually seeped out from the planet's interior. Remarkably, this subterranean water body is estimated to be three times the volume of all the oceans on the Earth's...

How Taiwan's Tallest Skyscraper Was Protected During An Earthquake by a Steel Ball

Image
Taiwan's highest tower is equipped with an innovative system that protects it from powerful winds and earthquakes. The "tuned mass damper" has a 40% reduction in the building's movement. Taipei 101, Taiwan's tallest tower, escaped with only minor damage from a recent 7.4-magnitude earthquake. CNN claims that its creative design, which incorporates a massive pendulum, is partially responsible for this. The building's central giant yellow pendulum served as a shock absorber. Called "Damper Baby," the pendulum is a tuned mass damper situated at the center of the structure, a 660-metric-ton steel sphere suspended over 1,000 feet above the ground. According to the news outlet, the sphere sways in response to the movement of the building during an earthquake or severe winds, lessening its sway by as much as 40%. The 41 steel layers that make up the pendulum are suspended between the 87th and 92nd levels. It swings within a restriction of 59 inches to preve...
