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 (AP) — Attorney General William Barr, one of President Donald Trump's staunchest allies, is resigning amid lingering tension with the president over the president's baseless claims of election fraud and the investigation into President-elect Joe Biden's son. Barr went to the White House on Monday, where Trump said he submitted his letter of resignation. "Just had a very nice meeting with Attorney General Bill Barr at the White House," President Trump tweeted on Monday. "Our relationship has been a very good one, he has done an outstanding job! As per the letter, Bill will be leaving just before Christmas to spend the holidays with his family." 670

WASHINGTON - President Trump signed 4 executive orders Friday afternoon which all aim to lower the cost of prescription drugs for Americans.The first executive order will require medical facilities to pass along discounts they receive on insulin and EpiPens to consumers. The second order will allow for the importation of prescription drugs from Canada and other countries.The third order aims to eliminate the "middle man" in prescription drug sales. "Nobody even knows who they are. But the middle men are making a fortune,” President Trump said Friday.The fourth executive order strives to bring Medicare’s drug prices more in-line with prices in other countries.Florida's Governor, Ron DeSantis, joined the press conference, along with administration representatives and Americans who have diabetes and other medical conditions.During Friday's event, President Trump said he and his administration has secured 90 percent of the world's supply of remdesivir, which has proven to be a reliable treatment option for Covid-19. These efforts were initially announced in early July by the U.S. Department of Health and Human Services.Reducing drug prices has been an ongoing effort of the Trump administration. In 2018, the president signed two pieces of legislation into law on Wednesday that aimed to inform consumers about drug prices.Both measures, the Know the Lowest Price Act and the Patient Right to Know Drug Prices Act, aim to end the drug industry's so-called gag orders of pharmacists, which prevent them from discussing cheaper price options with consumers.In 2019, A federal judge nixed a regulation that was a centerpiece of the Trump administration's efforts to bring down drug prices.US District Judge Amit Mehta of the District of Columbia vacated the Department of Health and Human Services' rule that would have required drug makers to include their list prices in TV ads, saying the agency had overstepped its authority."No matter how vexing the problem of spiraling drug costs may be, HHS cannot do more than what Congress has authorized," Mehta wrote at the time of the ruling in July 2019. "The responsibility rests with Congress to act in the first instance."President Donald Trump has been unable to land the big deal with Congress to curb drug costs.Democrats, including Joe Biden, are pushing a much more ambitious plan to empower Medicare to negotiate prices.Friday's orders come at a time when the pharmaceutical industry is racing to create a Covid-19 vaccine. 2498
