WASHINGTON (AP) — For much of the United States, invasive grass species are making wildfires more frequent, especially in fire-prone California, a new study finds.Twelve non-native species act as "little arsonist grasses," said study co-author Bethany Bradley, a University of Massachusetts professor of environmental conservation.Wherever the common Mediterranean grass invades, including California's southern desert, fires flare up three times more often. And cheatgrass , which covers about one-third of the Intermountain West, is a big-time fire promoter, Bradley said."I would not be surprised at all if invasive grasses are playing a role in the current fires but I don't think we can attribute to them directly," Bradley said.University of Utah fire expert Phil Dennison, who wasn't part of the study but says it makes sense, said, "In a lot of ways, California was ground zero for invasive grasses. Much of California's native perennial grassland was replaced by Mediterranean annual grasses over a century ago. This study doesn't look at invasive grasses in the areas that are burning in California, but invasive grasses are contributing to the fires there."Experts say the areas burning now in California are more shrubs and grasses than forests, despite what President Donald Trump tweeted over the weekend."This is a global problem," said University of Alberta fire expert Mike Flannigan, who wasn't part of the study but said it makes sense. "I think with climate change and human assistance we are moving to a grass world. One region they should have mentioned is Hawaii where wildfires are increasing in large part due to invasive grasses."Invasive species are spreading more because of climate change as warmer weather moves into new areas, said study lead author Emily Fusco, also of the University of Massachusetts. New England and the Mid-Atlantic are seeing new invasive and more flammable grasses, Bradley said.The study in Monday's journal Proceedings of the National Academy of Sciences looks at the connections between a dozen species of invasive grasses and fires nationwide, finding fires occur more often in places with the non-native grasses. But the study did not find a link between invasive grasses and the size of the fires.Four of these species, including cheatgrass and common Mediterranean grass, are in California. These grasses get dry and then watch out, Fusco said."When you start a fire normally you want kindling," Fusco said. "The grasses are, more or less, like kindling"If someone lights a match and throws in the middle of a forest, it is unlikely a fire will start, but throw it in a field of cheatgrass "and odds are that it's going to catch," Bradley said."We are the reason that invasive species are here. We are the reason that they get spread around," Bradley said.Flanagan noted that invasive plants that are not grasses also feed the wildfire problem.While most outside experts said the study was important, wildfire expert LeRoy Westerling at the University of California, Merced said that with wildfires the size is key so this study is less valuable because it measures frequency.While size matters in forest fires, study author Bradley said mid to small size fires are the ones "in everybody's backyard" and affect people and their buildings more. 3313

WASHINGTON — Congressional leaders appear to be on the brink of a COVID-19 economic aid package, but there's no deal yet. As negotiators went home from the Capitol Wednesday, agreement seemed near on legislation that would extend help to individuals and businesses and ship coronavirus vaccines to millions. Negotiators are working on a 0 billion package that would revive subsidies for businesses hit hard by the pandemic, help distribute new vaccines, fund schools and renew soon-to-expire jobless benefits. They're also looking to include new direct payments of about 0 to most Americans. There's intense pressure for a deal. Unemployment benefits run out Dec. 26 for more than 10 million people. Many businesses are barely hanging on after nine months of the pandemic. 786

WASHINGTON (AP) — Military suicides have increased by as much as 20% this year compared to the same period in 2019, and some incidents of violent behavior have spiked.Service members are struggling with isolation and other effects of COVID-19, in addition to the pressures of deploying to war zones, responding to national disasters and addressing civil unrest.The data is incomplete and causes of suicide are complex, but Army and Air Force officials say the pandemic is adding stress to an already strained force.The numbers vary by service. The Army’s 30% spike pushes the total up because it’s the largest service. 626

WASHINGTON (AP) — As coronavirus cases rise in more than half of the states, the Trump administration is urging the Supreme Court to overturn the Affordable Care Act, otherwise known as Obamacare.The administration’s high court filing Thursday came the same day the government reported that close to half a million people who lost their health insurance in the economic shutdown to slow the spread of COVID-19 have gotten coverage through HealthCare.gov.The administration’s legal brief makes no mention of the virus.Some 20 million Americans could lose their health coverage and protections for people with preexisting health conditions also would be put at risk if the court agrees with the administration. 716
