The colors of an autumn afternoon can be serene, brilliant and breathtaking.“As the days start getting shorter and the nights get longer, that's the cue that the trees get to change the foliage,” said climate scientist Astrid Caldas.That foliage requires a delicate dance of temperature and moisture to produce fall colors. It’s a dance potentially now in jeopardy due to climate change.“Because these things -- temperature and precipitation, rainfall -- are being affected, changed by climate, then the fall foliage can really get affected,” said Caldas, who is a senior climate scientist at the Union of Concerned Scientists, a nonprofit science organization.She said long-term shifting temperature trends and more rain will be disruptive to fall foliage in certain parts of the country.“We are seeing extreme precipitation increase, particularly in the Northeast and the Midwest,” Caldas said.That precipitation was evident in Minnesota, where people found themselves caught off-guard this year by an unusually early snowfall."I had to completely disassemble my fall leaf clean-up box and make sure my plow is still working,” said Greg Futchi, who is a landscape contractor. “We usually get all the leaves down before we see some snow, but not this year."All of that added moisture can lead to a shorter fall foliage season, Caldas said. Yet, repeated and ongoing droughts, like those seen in the western U.S., also bring their own set of problems to autumn leaves.“When it’s very dry, the colors get a little more muted also,” Caldas said. “So, drought can really kind of change completely the setup.”Scientists add that climate change isn’t just going to affect the ways leaves change their colors during the fall. It’s also going to potentially affect where those trees grow in the first place.“When the conditions start changing --like it's starting to get warmer further and further north--well, that's also a possibility that species are going to start migrating farther north,” Caldas said. “So, as different trees start moving to different areas, then the colors may change because the color depends on the tree.”That may mean having to travel farther north to see stunning red maples. It is a change that will be hard to stop unless action is taken on a global scale.“In the long run, if the countries and the whole world is not committed to really reducing emissions and changing to renewables and making that complete change, then it's going to be very hard for us not to see very drastic changes, because small changes are already happening,” Caldas said.Those changes are now encroaching on a time-honored spectacle, courtesy of Mother Nature. 2667

The College Football Playoff semifinal at the Rose Bowl is moving to AT&T Stadium in Arlington, Texas.Bill Hancock, executive director of the College Football Playoff, made the announcement in a statement Saturday night on the eve of the release of the final playoff rankings.The College Football Playoff and Rose Bowl "mutually agreed" to move the game because of the growing number of coronavirus cases in Southern California."We are pleased that parents and loved ones will now be able to see their students play in the game," Hancock said.The move came after several coaches expressed their dismay about possibly traveling to the Rose Bowl to play in a game where players' families wouldn't be allowed.Los Angeles County is under a stay-at-home order that took effect earlier this month. Pasadena, home to the Rose Bowl, has its own public health department but has mostly followed the county's practices during the pandemic.A source told The Associated Press that the Rose Bowl sought an exemption from the state of California to allow families to attend but was denied twice.Hancock said the game will still be played in the mid-afternoon on New Year's Day."We are very grateful to Rose Bowl officials and the city of Pasadena," Hancock said. "They have worked hard to listen to the concerns of the CFP, the teams that might have played there, and their state and government officials. The Tournament of Roses has acted in the best interest of the people who live in Southern California, and we're grateful to Cotton Bowl and AT&T Stadium officials for their ability to make this late switch possible." 1624
