President Joe Biden on Thursday unveiled plans for locally-led protection of 30% of U.S. land and water by 2030, a core of his agenda to address climate warming that builds on nature-saving efforts launched in Congress by lawmakers from Colorado and other western states. Natural land and water could draw down the heat-trapping air pollution that causes climate change, scientists say, and nature increasingly is understood as a life support system for human survival both inside cities and in rural areas. Preserving at least 30% of land and water by 2030, they say, is necessary to pull back from a catastrophic tipping point. Gov. Jared Polis issued a statement casting Colorado as a leader in cooperative “science-based approaches” toward the fulfillment of Biden’s climate objectives. Biden’s announcement “opens the door to a collaborative and sustainable path toward conserving our critical ecosystems, supporting the Colorado way of life, while closing the door to fears about broad … [Read more...] about Biden’s “30 by 30” plan could mean protecting 14 million more acres of land, water in Colorado

(CNN) By 2035, NASA wants to land humans on Mars . But reaching the red planet, on average around 140 million miles away , will be a mammoth feat. Colder than Antarctica and with little to no oxygen , Mars is a hostile environment. The longer it takes astronauts to get there and the longer they stay, the more they are at risk. That's why scientists are looking at ways to reduce trip time. Seattle-based company Ultra Safe Nuclear Technologies (USNC-Tech) has proposed a solution: a nuclear thermal propulsion (NTP) engine that could get humans from Earth to Mars in just three months. Currently, the shortest possible trip for an unmanned spacecraft is seven months, but a crewed mission is expected to take at least nine months. The idea of nuclear rocket engines dates back to the 1940s, but the technology has only recently been revisited as a solution for deep space exploration. Michael Eades, director of engineering at USNC-Tech, says … [Read more...] about Nuclear-powered rocket could get astronauts to Mars faster
“I feel like there are more reasons to be excited about improvised music today than at any time during my 41 years on the planet,” the jazz critic Nate Chinen tells Rolling Stone . He has a point, and you don’t need to be a diehard fan of the genre to appreciate it.
