The caravan of Central American migrants going through Mexico to the US border isn't ending. Instead, its participants will disperse into smaller groups after reaching Mexico City.While some will stay in Mexico to try to get refugee status there, others will continue north to the US border.Organizers of the caravan estimate that some 200 or so people will proceed all the way to the US border in the coming days, although the number could be higher. Last year, about 150 went all the way to the border, they said. 523

The Environmental Protection Agency will allow states to set their own emission standards for coal-fueled power plants, the Wall Street Journal reported Monday. Critics say the decision will result in much more carbon dioxide being released into the atmosphere.The Journal reported that acting EPA Administrator Andrew Wheeler signed a proposal that calls for states to regulate emissions from power plants, undoing a move from President Barack Obama that made those emissions regulated by the federal government for the first time."The entire Obama administration plan was centered around doing away with coal," Wheeler told the Journal in an interview. 662

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 Centers for Disease Control and Prevention have changed its definition of a “close contact,” which impacts the agency’s recommendation on who should quarantine amid the coronavirus pandemic.Previously, the CDC recommended that those who were within 6 feet for 15 minutes of someone infected with the coronavirus should quarantine for two weeks. Now, the CDC recommends that those who are in contact with someone infected for 15 minutes over a 24-hour period should quarantine.The CDC offers the following recommendations for those who have been in contact with someone recently infected with the coronavirus:Stay away from others, especially people who are at higher risk for getting very sick from COVID-19, such as older adults and people with other medical conditions, if possible.If you have been around someone with COVID-19, stay home and away from others for 14 days (self-quarantine) after your last contact with that person and monitor your health.If you have a fever, cough or other symptoms of COVID-19, stay home and away from others (except to get medical care or testing, if recommended).If you need support or assistance while in self-quarantine, your health department or community organizations may be able to provide assistance. 1258
