On global warming, we have 12 years left until the point of no return
Most of us will still be alive then. Maybe.
- It's statistically possible to make enough changes to stave it off, but politically it looks unlikely if attitudes at the top do not change.
- We're already seeing effects from a 1-degree (C) change.
- What can we do? There are a few things...
The problem, as I see it, is that there isn't the political will to make the serious changes we need to in order to stave this off.
Stave what off, you ask?
It's the point—an increase of 1.5 degrees C or 2.7 degrees F—at which the things that we take for granted, like arctic ice and even the ability to live anywhere near the equator, disappear. The UN Intergovernmental Panel on Climate Change (IPCC) just issued a report on this that is, well, terrifying.
The report is written by 91 authors and 40 review editors, and it features 133 contributing authors, 6,000 scientific references, and was subject to over 42,000 expert and government review comments before publication.

If we don't reverse the current trends in a huge way, then extreme drought, floods, wildfires, food shortages for millions of people across the globe will be the norm for everybody. Well, except, perhaps, for those living at one of the poles.
"One of the key messages that comes out very strongly from this report is that we are already seeing the consequences of 1 degree C of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice, among other changes," said Panmao Zhai, co-chair of IPCC Working Group I.
The report tells us we need to cut greenhouse gas emissions by 45 percent below 2010 levels by 2030 and net zero—that is, NO increase in greenhouse gas emissions—by 2050.
If we don't? All of what's in the paragraph above, as well as:
- Coral reefs? Gone.
- Extreme weather events? So commonplace, we'll forget what it used to be like. (Hellooooo, Michael.)
- A rise in sea levels of anywhere between 33 to hundreds of feet.
- The seemingly impossible prospect of humans and other creatures being unable to live anywhere near the equator, because the extreme heat will not be able to support life. (Well, except for those creatures who have adapted to do just that)

We're two-thirds of the way there now, and in 12 years, that is the tipping point at which we cannot affect anything anymore. In other words, that's when it goes beyond a 1.5 degree increase in global average temperatures and the "feedback loop" that is the Earth will deteriorate to a point where we will have no way to stop the process.
In fact, with the course we are currently on, it's going to be double that temperature; we've already seen an increase of 1 degree since pre-industrialization, and there's really nothing slowing it down.
"The window on keeping global warming below 1.5 degrees C is closing rapidly and the current emissions pledges made by signatories to the Paris Agreement do not add up to us achieving that goal," stated Andrew King, a climate science expert at the University of Melbourne.

The last time I researched this, 2050 was the year that they pegged. Moving that up by 20 years—effectively, the same as moving the atomic scientists' Doomsday Clock ahead by two minutes—makes it seem all that more pressing.
But given the political climate of the world right now, it looks extremely unlikely that we'll do anything about it.
So is it time to invest in beachfront property in Antarctica?
Since 99% of us can't do that, here are some ideas on what you can do, from the UN report.
The report says there must be rapid and significant changes in four big global systems: Energy, land use, cities, and industry. But it adds that the world cannot meet its target without changes by individuals, urging people to:
- Buy less meat, milk, cheese and butter and more locally sourced, seasonal food—and throw less of it away
- Drive electric cars, but walk or cycle short distances
- Take trains and buses instead of planes
- Use videoconferencing instead of business travel
- Use a washing line instead of a tumble dryer
- Thoroughly insulate homes
- Demand low carbon in every consumer product.
Emotional intelligence is a skill sought by many employers. Here's how to raise yours.
- Daniel Goleman's 1995 book Emotional Intelligence catapulted the term into widespread use in the business world.
- One study found that EQ (emotional intelligence) is the top predictor of performance and accounts for 58% of success across all job types.
- EQ has been found to increase annual pay by around $29,000 and be present in 90% of top performers.
Researchers hope the technology will further our understanding of the brain, but lawmakers may not be ready for the ethical challenges.
- Researchers at the Yale School of Medicine successfully restored some functions to pig brains that had been dead for hours.
- They hope the technology will advance our understanding of the brain, potentially developing new treatments for debilitating diseases and disorders.
- The research raises many ethical questions and puts to the test our current understanding of death.
What's dead may never die, it seems<p>The researchers did not hail from House Greyjoy — "What is dead may never die" — but came largely from the Yale School of Medicine. They connected 32 pig brains to a system called Brain<em>Ex</em>. Brain<em>Ex </em>is an artificial perfusion system — that is, a system that takes over the functions normally regulated by the organ. The pigs had been killed four hours earlier at a U.S. Department of Agriculture slaughterhouse; their brains completely removed from the skulls.</p><p>Brain<em>Ex</em> pumped an experiment solution into the brain that essentially mimic blood flow. It brought oxygen and nutrients to the tissues, giving brain cells the resources to begin many normal functions. The cells began consuming and metabolizing sugars. The brains' immune systems kicked in. Neuron samples could carry an electrical signal. Some brain cells even responded to drugs.</p><p>The researchers have managed to keep some brains alive for up to 36 hours, and currently do not know if Brain<em>Ex</em> can have sustained the brains longer. "It is conceivable we are just preventing the inevitable, and the brain won't be able to recover," said Nenad Sestan, Yale neuroscientist and the lead researcher.</p><p>As a control, other brains received either a fake solution or no solution at all. None revived brain activity and deteriorated as normal.</p><p>The researchers hope the technology can enhance our ability to study the brain and its cellular functions. One of the main avenues of such studies would be brain disorders and diseases. This could point the way to developing new of treatments for the likes of brain injuries, Alzheimer's, Huntington's, and neurodegenerative conditions.</p><p>"This is an extraordinary and very promising breakthrough for neuroscience. It immediately offers a much better model for studying the human brain, which is extraordinarily important, given the vast amount of human suffering from diseases of the mind [and] brain," Nita Farahany, the bioethicists at the Duke University School of Law who wrote the study's commentary, told <em><a href="https://www.nationalgeographic.com/science/2019/04/pig-brains-partially-revived-what-it-means-for-medicine-death-ethics/" target="_blank">National Geographic</a>.</em></p>
An ethical gray matter<p>Before anyone gets an <em>Island of Dr. Moreau</em> vibe, it's worth noting that the brains did not approach neural activity anywhere near consciousness.</p><p>The Brain<em>Ex</em> solution contained chemicals that prevented neurons from firing. To be extra cautious, the researchers also monitored the brains for any such activity and were prepared to administer an anesthetic should they have seen signs of consciousness. </p><p>Even so, the research signals a massive debate to come regarding medical ethics and our definition of death. </p><p>Most countries define death, clinically speaking, as the irreversible loss of brain or circulatory function. This definition was already at odds with some folk- and value-centric understandings, but where do we go if it becomes possible to reverse clinical death with artificial perfusion?</p><p>"This is wild," Jonathan Moreno, a bioethicist at the University of Pennsylvania, told <a href="https://www.nytimes.com/2019/04/17/science/brain-dead-pigs.html" target="_blank">the <em>New York Times</em></a>. "If ever there was an issue that merited big public deliberation on the ethics of science and medicine, this is one."</p><p>One possible consequence involves organ donations. Some European countries require emergency responders to use a process that preserves organs when they cannot resuscitate a person. They continue to pump blood throughout the body, but use a "thoracic aortic occlusion balloon" to prevent that blood from reaching the brain.</p><p>The system is already controversial because it raises concerns about what caused the patient's death. But what happens when brain death becomes readily reversible? Stuart Younger, a bioethicist at Case Western Reserve University, <a href="https://www.nature.com/articles/d41586-019-01216-4#ref-CR2" target="_blank">told <em>Nature</em></a> that if Brain<em>Ex</em> were to become widely available, it could shrink the pool of eligible donors.</p><p>"There's a potential conflict here between the interests of potential donors — who might not even be donors — and people who are waiting for organs," he said.</p><p>It will be a while before such experiments go anywhere near human subjects. A more immediate ethical question relates to how such experiments harm animal subjects.</p><p>Ethical review boards evaluate research protocols and can reject any that causes undue pain, suffering, or distress. Since dead animals feel no pain, suffer no trauma, they are typically approved as subjects. But how do such boards make a judgement regarding the suffering of a "cellularly active" brain? <a href="https://bigthink.com/philip-perry/after-death-youre-aware-that-youve-died-scientists-claim" target="_blank">The distress of a partially alive brain</a>? </p><p>The dilemma is unprecedented.</p>
Setting new boundaries<p>Another science fiction story that comes to mind when discussing this story is, of course, <em>Frankenstein</em>. As Farahany told <em>National Geographic</em>: "It is definitely has [sic] a good science-fiction element to it, and it is restoring cellular function where we previously thought impossible. But to have <em>Frankenstein</em>, you need some degree of consciousness, some 'there' there. [The researchers] did not recover any form of consciousness in this study, and it is still unclear if we ever could. But we are one step closer to that possibility."</p><p>She's right. The researchers undertook their research for the betterment of humanity, and we may one day reap some unimaginable medical benefits from it. The ethical questions, however, remain as unsettling as the stories they remind us of.</p>
Starting and running a business takes more than a good idea and the desire to not have a boss.
- Anyone can start a business and be an entrepreneur, but the reality is that most businesses will fail. Building something successful from the ground up takes hard work, passion, intelligence, and a network of people who are equally as smart and passionate as you are. It also requires the ability to accept and learn from your failures.
- In this video, entrepreneurs in various industries including 3D printing, fashion, hygiene, capital investments, aerospace, and biotechnology share what they've learned over the years about relationships, setting and attaining goals, growth, and what happens when things don't go according to plan.
- "People who start businesses for the exit, most of them will fail because there's just no true passion behind it," says Miki Agrawal, co-founder of THINX and TUSHY. A key point of Agrawal's advice is that if you can't see yourself in something for 10 years, you shouldn't do it.
After a decade of failed attempts, scientists successfully bounced photons off of a reflector aboard the Lunar Reconnaissance Orbiter, some 240,000 miles from Earth.
- Laser experiments can reveal precisely how far away an object is from Earth.
- For years scientists have been bouncing light off of reflectors on the lunar surface that were installed during the Apollo era, but these reflectors have become less efficient over time.
- The recent success could reveal the cause of the degradation, and also lead to new discoveries about the Moon's evolution.

NASA<p>The technology isn't quite new. During the Apollo era, astronauts installed on the lunar surface five reflecting panels, each containing at least 100 mirrors that reflect back to whichever direction it's coming from. By bouncing light off these panels, scientists have been able to learn, for example, that the Moon is drifting away from Earth at a rate of about 1.5 inches per year.<br></p><p style="margin-left: 20px;">"Now that we've been collecting data for 50 years, we can see trends that we wouldn't have been able to see otherwise," Erwan Mazarico, a planetary scientist from NASA's Goddard Space Flight Center in Greenbelt, Maryland, <a href="https://www.nasa.gov/feature/goddard/2020/laser-beams-reflected-between-earth-and-moon-boost-science" target="_blank" rel="dofollow">said</a>. "Laser-ranging science is a long game."</p>
NASA's Lunar Reconnaissance Orbiter (LRO)
NASA<p>But the long game poses a problem: Over time, the panels on the Moon have become less efficient at bouncing light back to Earth. Some scientists suspect it's because dust, kicked up by micrometeorites, has settled on the surface of the panels, causing them to overheat. And if that's the case, scientists need to know for sure.</p><p>That's where the recent LRO laser experiment comes in. If scientists find discrepancies between the data sent back by the LRO reflector and those on the lunar surface, it could reveal what's causing the lunar reflectors to become less efficient. They could then account for these discrepancies in their models.</p>
