The Summary Many young climate advocates see Kamala Harris as stronger on environmental issues than Joe Biden. President Joe Biden may have passed the United States’ most significant climate legislation ever, but many young environmental activists say they see Kamala Harris as stronger on the issue. But several young climate activists ages 16 to 29 said for them, the expansion of the fossil fuel industry during Biden’s presidency has clouded those successes. Harris’ young supporters have highlighted the settlements she secured as California attorney general with Chevron, BP and ConocoPhillips over their handling of hazardous materials. Sunrise Movement protesters gather near Vice President Harris' Brentwood home on April 14, calling on her to urge President Biden to declare a climate emergency.

☆ Mars could be creating 'giant whirlpools' deep within our planet's oceans
▼ + stars: | 2024-03-13 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +5 min

Mars may be 140 million miles away, but its gravitational pull could be impacting Earth's oceans. Scientists at the University of Sydney in Australia believe the red planet's tug is creating "giant whirlpools" in the oceans called eddies, which can shift the deep-sea floor. This, they claim, is part of a 2.4-million-year climate "grand cycle" on Earth that has been ongoing for at least 40 million years. The red planet's orbit and ours are locked in an intricate dance, and every so often, these line up so that Mars' gravitational pull on Earth is just a little more intense — this is called resonance. This information is crucial when refining models helping us see how our planet's intricate climate will progress over time.

NASA is shutting down a $2 billion project to test satellite refueling in space, it announced Friday, after the agency's auditor criticized the program's lead contractor, Maxar, citing "poor performance." The space agency said in a statement that the OSAM-1 — On-orbit Servicing, Assembly, and Manufacturing 1 — project was being discontinued after nearly a decade of work. NASA did not respond to CNBC's request for comment on how many personnel will be affected as a result of OSAM-1's cancellation. Maxar was taken private by private equity firm Advent International in May 2023 before being split into two businesses: Maxar Intelligence, focused on satellite imagery and analytics, and Maxar Space Systems, focused on spacecraft manufacturing. NASA's Goddard Space Flight Center in Maryland was leading the work on OSAM-1, with Maxar Space Systems as the project's prime contractor under multiple deals.

The slower solar wind, located in the same plane of the solar system as Earth, flows at a calmer 249 miles per second (400 kilometers per second). This flip causes the coronal holes to appear across the sun’s surface and release bursts of solar wind directly toward Earth.

WASHINGTON, April 26 (Reuters) - President Joe Biden and South Korean leader Yoon Suk Yeol are expected to agree on Wednesday to deepen collaboration meant to deter nuclear escalation by North Korea amid heightened anxiety about its growing arsenal of missiles and bombs, U.S. officials said. The Republic of Korea is South Korea's official name. The officials stressed that no U.S. nuclear weapons would be returned to the peninsula, and South Korea would continue not to have control over the U.S. nuclear arsenal. South Korea will also reaffirm its commitment to the nuclear non-proliferation treaty and its non-nuclear status, they said. It is only the second state visit Biden has hosted since he took office two years ago - the first such guest was France's president.

Solar maximum is a peak in the sun's activity that happens around the middle of each solar cycle. Mathew OwensThe solar maximum represents a peak in solar activity when the sun's magnetic field reaches its strongest and most disordered and dynamic point. NASA/Solar Dynamics ObservatorySolar cycles typically last 11 years, and the solar maximum happens roughly in the middle of each cycle. The sun's magnetic field reaches peak strength during solar maximum, generating an increase in events like solar flares and coronal mass ejections. These bursts are around four times as likely to occur during a solar maximum than a solar minimum.
