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.
Famous physicists like Richard Feynman think 137 holds the answers to the Universe.
- The fine structure constant has mystified scientists since the 1800s.
- The number 1/137 might hold the clues to the Grand Unified Theory.
- Relativity, electromagnetism and quantum mechanics are unified by the number.
Younger Americans support expanding the Supreme Court and serious political reforms, says new poll.
- Americans under 40 largely favor major political reforms, finds a new survey.
- The poll revealed that most would want to expand the Supreme Court, impose terms limits, and make it easier to vote.
- Millennials are more liberal and reform-centered than Generation Z.
A 2020 study published in the journal of Psychological Science explores the idea that fake news can actually help you remember real facts better.
- In 2019, researchers at Stanford Engineering analyzed the spread of fake news as if it were a strain of Ebola. They adapted a model for understanding diseases that can infect a person more than once to better understand how fake news spreads and gains traction.
- A new study published in 2020 explores the idea that fake news can actually help you remember real facts better.
- "These findings demonstrate one situation in which misinformation reminders can diminish the negative effects of fake-news exposure in the short term," researchers on the project explained.

How does misinformation spread?
