How scared should we be?
Sebastian Copeland is a photographer and environmental activist. Copeland grew up in France and Britain, and graduated from UCLA in 1987 with a major in film. Throughout the 1990’s, Copeland directed commercials – everything from soft drinks to sportswear – as well as music videos. He is also known for his celebrity portraiture; he’s taken pictures of Sandra Bullock, Kate Bosworth, and Orlando Bloom (who is also his cousin), among others. In recent years, Copeland has focused on environmental activism. He serves on the Board of Directors of Global Green USA and recently published Antarctica: The Global Warning
Question: How scared should we be?
Copeland: You know it’s important to be . . . And I’m quoting . . . I’m quoting somebody and I can’t remember his name. But it’s . . . It’s important not to be an alarmist, but it’s important to be alarmed. Whether or not we have passed the cryptical . . . the cryptic tipping point, that is, is impossible for me to tell you. It’s impossible for most scientists to tell you. What I can tell you is that things are progressing in a way that have defined a trend. And that trend has been, in my estimation, undeniably associated with the development of the . . . of industrial activities and manmade activities associated with our use of hydrocarbon energy and our demographic growth. What I can tell you is that that growth in the carbon output into the atmosphere is non-linear. And it is not as classically progressive as what we would love to be able to see because it sort of moves forward. But the trend is definitely growing upwards, and that is just undeniable. So where is the cryptic tipping point? Well you know there’s a general acceptance in the scientific community that 550 parts per million of carbon – that is per air . . . per . . . per air – yes oxygen – is the . . . is the cryptic tipping point, and that we are presently at 430, and that we’re growing at a rate of about two parts per million per year. So this would put us at about 250 . . . 2050 as a place where if we were to exceed 250 parts per million, we would not be able . . . The increase in changes would be of such consequences that we would be thrown into an irreversible and accelerated process of warming up. I don’t necessarily believe that it’s gonna take that long. I also . . . I’m not exactly sure that we can be 100 percent certain that 550 parts is already . . . is the cryptic tipping point, because we are seeing changes that are being accelerated today in the, you know . . . how our glaciers are receding; obviously the polar cap is melting; and how different environments around the world are being impacted by a change in seasons, and by an increase in strong storms – by hurricane strength storms; by areas that are seeing, you know, an increase in drought while other areas are seeing an increase in torrential rains and whatnot. And we also know that these processes are exponential; that they’re sort of . . . They’re like a self-fulfilling mechanism, and it is confounding experts. I mean the environmental science is relatively new. It’s essentially 40 to 50 years old, and models . . . computer models are obviously becoming more and more sophisticated as our interests are being developed in that area. And what I will say is scientists are being confounded by the rate of change. So as such I am conservatively siding on the fact that they are looking at this and going look, we can project. But every year, and sometimes every six months, we are reassessing our projections. And you know the IPCC, and the UN . . . the Intergovernmental Panel on Climate Change has made some projections which were revised within a period of six months and saw some dramatic revisions.

It’s important not to be an alarmist, but it’s important to be alarmed, Copeland says.

Health officials in China reported that a man was infected with bubonic plague, the infectious disease that caused the Black Death.
- The case was reported in the city of Bayannur, which has issued a level-three plague prevention warning.
- Modern antibiotics can effectively treat bubonic plague, which spreads mainly by fleas.
- Chinese health officials are also monitoring a newly discovered type of swine flu that has the potential to develop into a pandemic virus.
Bacteria under microscope
needpix.com<p>Today, bubonic plague can be treated effectively with antibiotics.</p><p style="margin-left: 20px;">"Unlike in the 14th century, we now have an understanding of how this disease is transmitted," Dr. Shanthi Kappagoda, an infectious disease physician at Stanford Health Care, told <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">Healthline</a>. "We know how to prevent it — avoid handling sick or dead animals in areas where there is transmission. We are also able to treat patients who are infected with effective antibiotics, and can give antibiotics to people who may have been exposed to the bacteria [and] prevent them [from] getting sick."</p>
This plague patient is displaying a swollen, ruptured inguinal lymph node, or buboe.
Centers for Disease Control and Prevention<p>Still, hundreds of people develop bubonic plague every year. In the U.S., a handful of cases occur annually, particularly in New Mexico, Arizona and Colorado, <a href="https://www.cdc.gov/plague/faq/index.html" target="_blank">where habitats allow the bacteria to spread more easily among wild rodent populations</a>. But these cases are very rare, mainly because you need to be in close contact with rodents in order to get infected. And though plague can spread from human to human, this <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">only occurs with pneumonic plague</a>, and transmission is also rare.</p>
A new swine flu in China<p>Last week, researchers in China also reported another public health concern: a new virus that has "all the essential hallmarks" of a pandemic virus.<br></p><p>In a paper published in the <a href="https://www.pnas.org/content/early/2020/06/23/1921186117" target="_blank">Proceedings of the National Academy of Sciences</a>, researchers say the virus was discovered in pigs in China, and it descended from the H1N1 virus, commonly called "swine flu." That virus was able to transmit from human to human, and it killed an estimated 151,700 to 575,400 people worldwide from 2009 to 2010, according to the Centers for Disease Control and Prevention.</p>There's no evidence showing that the new virus can spread from person to person. But the researchers did find that 10 percent of swine workers had been infected by the virus, called G4 reassortant EA H1N1. This level of infectivity raises concerns, because it "greatly enhances the opportunity for virus adaptation in humans and raises concerns for the possible generation of pandemic viruses," the researchers wrote.
The word "learning" opens up space for more people, places, and ideas.
- The terms 'education' and 'learning' are often used interchangeably, but there is a cultural connotation to the former that can be limiting. Education naturally links to schooling, which is only one form of learning.
- Gregg Behr, founder and co-chair of Remake Learning, believes that this small word shift opens up the possibilities in terms of how and where learning can happen. It also becomes a more inclusive practice, welcoming in a larger, more diverse group of thinkers.
- Post-COVID, the way we think about what learning looks like will inevitably change, so it's crucial to adjust and begin building the necessary support systems today.

Every summer, children on the Alaskan island of St Paul cool down in Lake Hill, a crater lake in an extinct volcano – unaware of the mysteries that lie beneath.
The coronavirus pandemic has brought out the perception of selfishness among many.
- Selfish behavior has been analyzed by philosophers and psychologists for centuries.
- New research shows people may be wired for altruistic behavior and get more benefits from it.
- Times of crisis tend to increase self-centered acts.
