The most common side effects were pain, redness and swelling at the injection site, limited arm movement, fatigue, headache, muscle pain, joint pain, less appetite, vomiting, fever, chills, or rash. Even if youve already been vaccinated with another pneumonia vaccine, prevnar 13® may help provide additional protection. Get this one done. Ask your doctor or pharmacist about prevnar 13® today. Pelley President Trump has been at Walter Reed Military Medical Center for two days, under treatment for covid19. His doctors said today he may be ready for discharge as early as tomorrow to continue his therapy at home at the white house. Theyve had him on a fiveday regimen of the antiviral drug remdesivir as well as a mix of monoclonal antibodies, a therapy which is still in the testing phase. More than a dozen people in the president s orbit have now tested positive for covid. In a video late yesterday the president reported hes feeling better and predicted he will be back soon. When he returns to the oval office, many crises await him, including the wildfires in the west. At least 31 have died in the largest wildfires in california history. The east is defending itself against twice the usual number of tropical cyclones. And what may be the highest temperature ever recorded on earth came in august in the United States. Its a torrid 2020 and it was forecast 32 years ago. In the 1980s, a nasa scientist named james hansen discovered that Climate Change, driven by carbon emissions, was upon us. His graphs, of three decades ago, accurately traced the global rise in temperature to the year 2020. Last week, we had a lot of questions for hansen. Are these disasters Climate Change . Do things get worse . Is it too late to do anything . But before we get to the causes let us show you the effects. Butte county, california, volunteer fire station 61. How long has the fire station been here . Rankin about 35 years. Pelley and how long have you been here . Rankin twentyeight and a half years. Pelley reed rankin is chief of what was station 61. Hes spent his life in the community of berry creek. Hes on the school board and built his home with his own hands. Tell me what your home looks like right now. Rankin nothin but a foundation with a metal roof on top of it. Its completely burned down. Pelley school burned down. Rankin yeah. Completely. All the buildings on it burned down. Nothin nothin left. Pelley 15 people died in that inferno, the second week in september, north of sacramento, where the Central Valley folds into the Sierra Nevada. Tom porter these are fires that nobody, when i started in this business, ever even dreamed of happening in california. Not even close. Pelley california state fire chief thom porter started in this business in 1999. That year just over one million acres burned. By 2007, it was a million and a half. In 2018, two million. This season, nearly four million acres have burned so far. Climate isnt the only reason. Decades of aggressively putting out every forest fire allowed brush to pile up like kindling. But the warming climate has intensified heat and drought. Chief porter showed us the length of the fire lines hes defending right now would porter they talk about career fires. And a career fire was sometimes on the order of 10,000 to 50,000 acres. 50,000, that was crazy. Pelley the kind of thing a firefighter would see once in his career. Porter correct. Once in a career. It dawned on me at one point that career fires are happening every single year, right now, today, there are ten fires in california that are 100,000 acres plus, and one thats 850,000 acres plus. Pelley four percent of the state has burned in total. The largest fires were ignited by stormsbut because the air is so drythe rain evaporated before it reached the groundleaving chief porter fighting dry lightning. Porter im afraid, without significant change in the moisture that we get from the atmosphere were gonna continue to see this getting worse and worse and worse. Pelley how much of california can burn . Porter every acre in california can and will burn someday. Pelley california smoke blew more than 2,000 miles to the east and drifted over the pennsylvania farm of retired nasa scientist, james hansen. His 1988 paper on carbon and climate accurately predicted temperatures up to the faroff year of 2020. Hansen yeah, were seein exactly what we expected. But i expected that governments would be wise enough that they would begin to adopt policies to preserve the future for young people. But they havent done that yet. Pelley hansen is the father of Climate Change science. For 32 years he was director of Nasas Goddard institute for space studies. Today at 79, he runs the program liciivsity. What is your forecast for the next 30 years . Hansen well, if we dont change anything, then were going to continue to see more and more of these extreme regional events because the physics is quite simple. As you add more Greenhouse Gases to the atmosphere, you increase the heating of the surface. So, at the times and places where its dry, you get more extreme droughts. The fire seasons become longer. The fires burn hotter. But at the times and places where its wet, you get more evaporation of the water. And you get warmer, moist air, which provides greater rainfall. And its the fuel for storms. Pelley this summer, the Atlantic Basin has soaked beneath 23 tropical storms or hurricanes double the usual number. Death valley, california, hit 130 degrees, now being evaluated as a world record. And los angeles reached 120. Michael mann people ask, are we dealing with a new normal . And the sobering answer is, thats the bestcase scenario. A new normal is the bestcase scenario cause that sort of means, well, weve got a new situation and we just have to learn how to deal with it. But its much worse than that. So, there are surprises in store and were seeing some of those surprises play out now. Pelley michael mann is a geophysicist whose work on past climate showed todays rate of warming began with the industrial revolution. Mann is a lightning rod for deniers, but his research has been verified again and again. Mann is director of the Earth System Science Center at penn state and a member of the National Academy of sciences. But thereve always been fires in the west. Thereve always been hurricanes in the east. How do we know that Climate Change is involved in this . Mann well, there are a number of independent sort of sources of information, lines of evidence that tell us that this isnt natural, that this is human caused. Lets look at the big picture, the warming of the planet a little less than two degrees fahrenheit warming of the planet since preindustrial time. Now, people ask, well, couldnt that happen naturally . Well, it turns out that if you look at the factors that are driving natural changes right now small but measurable fluctuations in the brightness of the sun, volcanic eruptions they tell us that earth shouldve cooled slightly over the past halfcentury. Pelley heres what he means. In that yellow line at bottom, nasa has measured a steady decline in heat from the sun since the 1950s but the red line, the temperature of the earth, has only increased. Mann we can only explain that warming when we include the human factor of increased Greenhouse Gas concentrations; in particular, Carbon Dioxide from the burning of fossil fuels. Pelley well, the president says about Climate Change, science doesnt know. Mann the president doesnt know. And he should know better. He should know that the worlds leading scientific organizations, our own u. S. National academy of sciences, and National Academies of every Major Industrial nation, every Scientific Society in the United States thats weighed in on the matter. This is a Scientific Consensus. Theres about as much a Scientific Consensus about humancaused Climate Change as there is about gravity. Pelley thats what President Trump heard last month from wade crowfoot, head of californias Natural Resources agency, which includes fire fighting. Crowfoot because if we ignore that science and sort of put our head in the sand and think its all about vegetation management, were not going to succeed together protecting californians. Trump okay. Itll start getting cooler. You just watch. Crowfoot i wish science agreed with you. Trump well, i dont think science knows, actually. Crowfoot well, with respect, i think hes wrong and hes on the wrong side of history. Pelley this is the unmasked wade crowfoot, who reminded us california emerged from a five year drought in 2016. Crowfoot in that drought, which we called a megadrought, hasnt happened at that level in a thousand years. We experienced communities in california literally running out of water. Pelley and where california dried out is now the site of the largest single fire in state historycalled the creek fire. Crowfoot so thats an existential challenge. We lost over 160 Million Trees in the Sierra NevadaMountain Range as a result of that drought. The fire that burned the hottest and most dangerous, the creek fire, was in the epicenter of that tree mortality. It ran so hot that it created a smoke cloud 50,000 feet in the sky. Pelley what was the impact of all the smoke . Crowfoot so consider this. 50 million americans on the west coast suffered through weeks of the worst air quality on the planet. Pelley you didnt have to live anywhere near the fires to be affected by them. Crowfoot not at all. Throughout california the smoke was so bad that our kids couldnt play outside. And folks were discouraged from even spending any time outdoors. Pelley i did my first climate story more than 20 years ago and i remember, at the time, being told that there would be terrible fires and terrible hurricanes in 100 years; that this was a problem for our greatgrandchildren. What changed . Mann what were finding is that many of these changes can happen faster than we thought they could. We didnt really expect to see substantial loss of ice from the two major continental ice sheets, the Greenland Ice sheet and the Antarctic Ice sheet. But now, the satellite measurements and in situ measurements tell us that theyre already losing ice. Theyre already beginning that process of collapse. Its already contributing to Sea Level Rise, decades ahead of schedule. Pelley still, geophysicist michael mann told us warming can be stopped. Oceans and forests would begin to absorb excess carbon in a matter of years if emissions, principally from coalfired power plants, are reduced close to zero. Former nasa scientist james hansen believes the way to do that is for governments to tax cheap fossil fuels to make them more expensive than clean alternatives. Hansen they have these Wishful Thinking agreements like kyoto protocol and the paris agreement. Every country says, well try to do better. That wont work. What we need is to have an increasing price on the fossil fuels and do it in a way that the public will accept. Pelley at what point does it become too late . Hansen it becomes too late if you get to the point that you cannot stop the ice sheet disintegration. Thats the biggest point of no return. We can get to a point where were going to get several meters of Sea Level Rise out of our control. Thats too late. We would lose our coastal cities. And more than half of the large cities in the world are on coastlines. Pelley if we dont start to mosp, 50 yearsm now, someone doing research on this time might look at this interview and i wonder what you would like to say to them. Mann thatthats a tough question. I would say we did everything we could and were sorry. Were sorry that we failed. But i dont think thats our future. I dont want that to be our future. Thats a possible future. We have to recognize that. The worst visions that hollywood has given us of dystopian futures are real possible futures; if we dont act on this problem, the greatest crisis that we face as a civilization. ticking orizons and that sticked to my mind. So, when 1 a day came out, i said, why not . Why not just utilize that resource. And walmart made that path open for me. Without the 1 a day program, i definitely dont think id be in school right now. Each week for me in school is just an accomplishment. I feel proud every step of the way. vo purina one.

People with autism have a spectrum of abilities and disabilities. Some are unable to speak, or care for themselves, while others can live on their own and have unique skills like excellent memory or attention to detail. No matter where they are on the spectrum, many adults with autism have a difficult time finding a job. Even making it past a first interview can be challenging. But that may be starting to change. As we found out, more companies are discovering the potential of people with autism, and some are now actively recruiting for talent on the spectrum. Ewan b
