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.

Construction of the $500 billion dollar tech city-state of the future is moving ahead.
- The futuristic megacity Neom is being built in Saudi Arabia.
- The city will be fully automated, leading in health, education and quality of life.
- It will feature an artificial moon, cloud seeding, robotic gladiators and flying taxis.
The Red Sea area where Neom will be built:

Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.
