Earth sweltered to a record hot September last month, with U.S. climate officials saying there’s nearly a two-to-one chance that 2020 will end up as the globe’s hottest year on record.Boosted by human-caused climate change, global temperatures averaged 60.75 degrees (15.97 Celsius) last month, edging out 2015 and 2016 for the hottest September in 141 years of recordkeeping, the National Oceanic and Atmospheric Administration said Wednesday. That’s 1.75 degrees (0.97 degrees Celsius) above the 20th century average.This record was driven by high heat in Europe, Northern Asia, Russia and much of the Southern Hemisphere, said NOAA climatologist Ahira Sanchez-Lugo. California and Oregon had their hottest Septembers on record.Earth has had 44 straight Septembers where it has been warmer than the 20th century average and 429 straight months without a cooler than normal month, according to NOAA. The hottest seven Septembers on record have been the last seven.That means “that no millennial or even parts of Gen-X has lived through a cooler than normal September,” said North Carolina state climatologist Kathie Dello, herself a millennial.What’s happening is a combination of global warming from the burning of coal, oil and natural gas and natural variability, Sanchez-Lugo said. But the biggest factor is the human-caused warming, she and Dello said.The globe set this record despite a La Nina, which is a cooling of parts of the central Pacific that changes weather patterns and usually slightly lowers temperatures.“A La Nina is no match for how much we’re warming the planet,” Dello said.The first nine months of 2020 are the second warmest on record, a shade behind 2016 when there was a strong warming El Nino. But Sanchez-Lugo said her office’s calculations show that there’s a 64.7% chance that 2020 will pass 2016 in the last three months to take the title as the warmest year on record. And if it doesn’t make it, she said it’ll easily be in the top three, probably top two.“We’re catching up” to 2016, Sanchez-Lugo said. “It’s a very tight race.”With the climate trend, heat records that looked like it would take many years to break get passed quicker, said Colorado University weather data scientist Sam Lillo.___Follow AP’s climate coverage at https://www.apnews.com/Climate___Follow Seth Borenstein on Twitter at @borenbears .___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

Do you prefer to select your numbers when playing the lottery? Well, if you’re opting to select your own numbers for the Mega Millions drawing, there are some numbers that win the most.The first Mega Millions drawing was in September of 1996.  Since then, there have been more than 2,200 drawings.According to Lottonumbers.com--a website that analyzes lottery numbers--the number drawn the most is the number 2. It's been picked 219 times.The second most picked numbers were 17 and 31. Followed by 39 and then 4 and 46.Something to keep in mind: the game started with 50 numbers in the drawing in 1996. More numbers were added on in 1999, 2002, 2005 and 2013.Presently, there are 75 numbers to choose from and can be configured into nearly 300 million possible combinations for winning.The yellow ball is the one that matters, so you may think about selecting the number 3.It has been chosen the most; 89 times in the more than 2,000 draws.There are also numbers that were drawn the least. Those include 72, 71, and 67. Those numbers have been drawn fewer than 25 times.When it comes to the Mega Millions number, 51 has been chosen only once!But keep in mind that the higher numbers were just added to the drawing in the last few years. 1249

Dr. Anthony Fauci said the country is at a critical place during the pandemic, and that the worst is probably still ahead. Despite warnings about traveling and getting together with people outside a household, Fauci feared another surge on top of the current surge following the Christmas holiday.“We very well might see a post-seasonal — in the sense of Christmas, New Year’s — surge, and as I’ve described it, as a surge upon a surge,” Fauci said on CNN’s “State of the Union.”“I share the concern of President-elect Biden that as we get into the next few weeks it might actually get worse,” Fauci continued.During the interview, he also expressed optimism about the speed of vaccinations happening across the country.As of Monday morning, almost 2 million Amerians have received the first dose of either Pfizer or Moderna’s two-dose COVID-19 vaccine. Nearly 10 million doses have been distributed to states, the CDC reports.Over the weekend, Fauci said he now believes the country will need to reach a 80-85% rate immunity to reach so-called herd immunity. This is an increase over earlier estimates, which were closer to 70%.On Sunday, Senator Marco Rubio called out Fauci in a tweet questioning the change.“Dr. Fauci lied about masks in March. Dr. Fauci has been distorting the level of vaccination needed for herd immunity. It isn’t just him. Many in elite bubbles believe the American public doesn’t know ‘what’s good for them’ so they need to be tricked into ‘doing the right thing,’” Rubio’s tweet says. 1520

Due to the wildfires raging in Northern California, San Francisco, Stockton and Sacramento were the world's three "most polluted cities" on Friday morning, according to Berkeley Earth, a nonprofit that aggregates data from air-quality monitoring sites.PurpleAir, which has a network of sensors around the world, also showed that California had worse air than traditional smog hotspots in India and China.CNN meteorologist Brandon Miller confirmed that "no region on Earth had as many air quality stations in the highest ranges" of particulate matter, or PM, the toxic mixture of particles and droplets that worsens after wildfires.Those values, he said, "stretched for hundreds of miles over Northern and Central California, from the mountains to the valleys and the coast."Schools, colleges and public transit have closed as smoke from the Camp Fire descends on the region."It appears to be the worst air quality ever experienced in San Francisco," said Dan Jaffe, a professor of environmental chemistry at the University of Washington. He called the situation "an air quality emergency," and experts said the smoke could undo decades of progress on pollution."We have made tremendous efforts and investment to clean up our air with considerable benefits for public health," said Dr. Daniel Jacob, a professor of atmospheric chemistry and environmental engineering at Harvard University. "But now it's like we're getting stabbed in the back with those wildfires." 1472

Devastating wildfires across the Western United States has sent smoke traveling across the country and even into Europe. With that smoke comes bad air quality, not just for those near the fires, but for the entire continent.Satelite images from NASA shows smoke thousands of miles from the fire. NASA says the smoke contains aerosols, a combination of particles which carry harmful things into the air and into your lungs. All the things that are burning, trees, grass, brush, homes, are turned into soot and absorbed by our lungs.“This pollution, nobody knows how badly it will be affected but if we extrapolate from previous air quality it's not good,” Dr. Malik Baz, the medical director at the Baz Allergy and Sius Center, said. “The long-term side effect, we’ll see many, many years down the line.”Baz’s operates 13 locations in California, all of them are busy as Central California is essentially a big bowl surrounded by mountains which trap pollution over the valley. Air quality is always an issue for this part of the state and fires multiply the problem.“People with respiratory, allergy, asthma, ,sinus problem, anytime the air quality goes bad, their symptoms get worse,” Baz said. “It affects them but this air quality, it doesn’t matter whether you have respiratory problems or not, everyone is affected.”It's bad in other western cities too."This is really an unprecedented wildfire season in 2020,” said Jon Klassen, director of air quality science and planning for San Joaquin Valley Air Pollution Control District. “We have fires across most of the states in the western US, Washington, Oregon, California, Seattle. Portland has some of the worst air quality in the world right now, which is shocking because normally they have pretty good air quality."Klassen’s job is to monitor and improve air quality and help reduce emissions.“Those sorts of emissions can come off of wildfires or different industrial sources, the burning of different material, and the challenge and the health challenge is that because it’s so small, it can get into your lungs, your bloodstream, cause damage to internal organs,” Klassen said.A good air quality index score is anywhere from 0 to 50. Some of the cities next to the fires are seeing numbers in the 400s or 500s. California, Klassen says, has had fires burn 3.4 million acres. That's larger than the state of Connecticut as a whole. And that smoke from the western United States isn't just staying local.“Just the enormous amount of emissions that are going into the atmosphere can get caught up in transport flow from the Pacific over to the Atlantic,” Klassen said. “It can slowly cross the content and into different parts of the country, which is what we’re observing right now.”Which means use the "see and smell" rule, and watch the air quality index wherever you are.Sometimes that air can make you feel bad, and doctors advise you watch your symptoms.“[Symptoms include] lethargy, coughing, wheezing, difficulty breathing, irritation of the eyeballs, sneezing, itching, nasal congestion, headaches,” Baz said. These are also the symptoms of COVID-19, which makes some problems hard to diagnose.If your air quality isn't good, Baz suggests staying in, avoiding strenuous exercise outside, changing the filters in your home and car and keeping up on your medications and hydration.And while fires aren't forever, we are unfortunately just starting a season that's shaping up to be unprecedented.“The concern here is we are in the middle of wildfire season,” Baz said. “The past few years, the season has ended in November and we’re in September, so we’ll have a couple months left to go with these fires.” 3678
