The world’s coming fresh water crisis will be a catastrophe for many major cities

We can see the fresh water catastrophe coming, but will we do enough in time to avert it? This video lays out the problem:

Explained | World’s Water Crisis | FULL EPISODE | Netflix

According to the video, these cities are on the brink of a fresh water crisis unless action is taken:

  • Cape Town, South Africa
  • Sao Paulo, Brazil
  • Melbourne, Australia
  • Jakarta
  • London
  • Beijing
  • Istanbul
  • Tokyo
  • Bangalore
  • Barcelona
  • Mexico City

Other well known problem areas are dry places like Las Vegas, Saudi Arabia (and many other desert areas in the Middle East and Africa), parts of China and India, etc. These places currently rely on aquifers that are going to soon be empty.

Some of the large urban areas are coastal so they will eventually resort to mass desalination (with its own pollution and energy problems, but better than dying of thirst), but a place like Mexico City or Las Vegas may not be so lucky.

This article paints a dire picture:

More than 3 billion people affected by water shortages, data shows – UN warns about consequences of not conserving water and tackling climate crisis

Water shortages are now affecting more than 3 billion people around the world, as the amount of fresh water available for each person has plunged by a fifth over two decades, data has shown. About 1.5 billion people are suffering severe water scarcity or even drought, as a combination of climate breakdown, rising demand and poor management has made agriculture increasingly difficult across swathes of the globe.

With human populations continuing to rise, the problems only get worse unless something causes the human population to crash.

One possible solution is purely economic. Municipal water in a place like Las Vegas might be a penny per gallon today. If it rises to 50 cents or a dollar per gallon, then people will treat water differently. It might mean the end of golf courses and giant artificial lakes in the desert:

Scientists say net zero by 2050 is too late

Scientists say net zero by 2050 is too late

From the article:

CRC quotes British Professor of Energy and Climate Change Kevin Anderson as saying the world is currently on a path to 3–5ºC warming by 2100. He warned that a 4°C warmer future is “incompatible with an organised global community”. That sort of temperature rise is “beyond adaptation”, he said, because it will “devastate the majority of ecosystems and has a high probability of not being stable”.

A further problem is that climate change is not one thing, but many. Humans must take extraordinary steps now or watch a disaster unfold through multiple mechanisms:

But it is too little too late. The pace of change must accelerate dramatically.

Many parts of the world will become uninhabitable to humans and animals as the planet heats up

Planet Earth is growing warmer, and as it does we will see parts of the planet become uninhabitable due to heat and humidity. The southeastern United States is vulnerable to this – it will be impossible to go outside without an air conditioned vehicle or suit:

Climate Change Will Make Parts of the U.S. Uninhabitable. Americans Are Still Moving There.

From the article:

The data shows that the warming climate will alter everything from how we grow food to where people can plausibly live. Ultimately, millions of people will be displaced by flooding, fires and scorching heat, a resorting of the map not seen since the Dust Bowl of the 1930s. Now as then, the biggest question will be who escapes and who is left behind.

It’s crazy to think that it will come to this – that humans will choose to destroy the planet instead of taking action to stop the burning of fossil fuels. Nonetheless, this is the path humanity is following right now, and it will have gigantic economic and social costs for all human beings unless we as a species change course. See the Global Warming chapter for details. And this video paints a dire picture:

Arctic Temperatures point toward extreme warming for the entire planet

This article paints a dire picture:

It’s Way Too Hot in the Arctic Right Now

From the article:

In the latest sign that the transformation of the Arctic continues full speed ahead, Svalbard hit a record high temperature for November on Wednesday. A station set on the mountain pass of Reindalspasset recorded a high of 49 degrees Fahrenheit (9.4 degrees Celsius). That is, to put it lightly, extremely not normal and very bad.

The “very bad” part is going to get even worse as humans pour more and more carbon dioxide into the atmosphere. The only solution is to immediately stop burning all fossile fuels and to start extracting carbon dioxide from the atmosphere to reverse the process:

Any hope of keeping Earth habitable now requires sucking carbon back out of the atmosphere, a new study found

From the article:

Even if we stopped emitting greenhouse gas today, the Earth would continue warming for centuries. Arctic ice and permafrost are already on an irreversible path of melting. That’s the finding of new research published Thursday in the journal Scientific Reports. The model suggests that even if emissions were to drop to zero this year, global temperatures would ultimately rise to be 5.4 degrees Fahrenheit higher in 2500 than they were in 1850 (that’s 3 degrees Celsius).

Humans must take extraordinary steps now or watch a disaster unfold through multiple mechanisms:

Our young are terrified by climate change

The headline is “Our young are terrified by climate change” and they have every reason to be. “Climate change” is not just one thing. As the climate changes due to the combustion of fossil fuels, many different things happen including:

Our young are terrified by climate change

From the article:

“I often ask people to describe how they feel about their future given the specter of climate change, using just one word. The words I hear are painful — “fearful,” “concerned,” “terrified,” “frightened,” “hopeless” and — the most painful — “black”from a 20-something. The words I hear are not unusual — over half of U.S. teens feel afraid or angry. And I have also heard apathy — no one cares. Most of those I ask are college students with their life aheadAsk someone younger for their one word. Start with your children or grandchildren. Their word may frighten you.”

They have every reason to feel terrified and hopeless. This is an incredible doomsday scenario barreling down the tracks toward us, and humanity appears to be doing nothing concrete to stop it.

Hurricane frequency and damage are becoming epic as Global Warming provides the fuel

Hurricanes cross the Atlantic ocean and gather their energy + water from warm ocean waters. So it makes sense that global warning will increase hurricane strength as oceans warm up.

Now we start to see the doomsday scenario unfold. This year the Atlantic ocean spawned the most hurricanes ever:

Subtropical Storm Theta Makes 2020 Busiest Hurricane Season On Record

“Monday, Subtropical Storm Theta became the 29th named storm of the year, surpassing the 28 storms of 2005 and making the 2020 hurricane season the busiest on record.”

With so many hurricanes in play, it is inevetable that they start overlapping their destructive paths, so we get situations like this:

‘Nothing Left’: How Back-to-Back Hurricanes Gutted a U.S. Town

What’s happened to Cameron is a taste of what may be coming for other towns along the Gulf Coast as climate change takes hold. Warmer Gulf water and moister air are the kindling for tropical cyclones, helping to make them more ferocious. The 2020 hurricane season isn’t over, and it’s already produced 25 named storms. That’s the most since 2005, when Hurricane Katrina all but drowned New Orleans. At least seven hurricanes have struck Southwestern Louisiana in the last 20 years, twice as many as the previous two decades.

The problem is that it is likely to get worse rather than better unless drastic action on global warming and climate change takes place on a global level. Humans need to completely stop emitting carbon dioxide from fossil fuels and start extracting CO2 back out of the atmosphere. Humans may need to consider geoengineering techniques. And more.

New Methane releases portend an unstoppable feedback loop of global warming

One big worry in the scientific community is that the arctic permafrost starts to thaw out, and in the process it releases massive quantities of methane. Methane is a greenhouse gas far more powerful than carbon dioxide, so it doesn’t take much methane to have an effect on global warming.

‘Sleeping giant’ Arctic methane deposits starting to release, scientists find – Exclusive: expedition discovers new source of greenhouse gas off East Siberian coast has been triggered

Scientists have found evidence that frozen methane deposits in the Arctic Ocean – known as the “sleeping giants of the carbon cycle” – have started to be released over a large area of the continental slope off the East Siberian coast, the Guardian can reveal. High levels of the potent greenhouse gas have been detected down to a depth of 350 metres in the Laptev Sea near Russia, prompting concern among researchers that a new climate feedback loop may have been triggered that could accelerate the pace of global heating.

The problem is that once this cycle gets started, it can create a positive feedback loop. The methane that is being released causes heating that causes more methane to be released and so on, vastly accelerating the pace of global warming.

There is also methane leaking out under Antarctica for the first time:

First Methane Leak Found on Antarctic Sea Floor Confirms Researchers’ Fears

Scientists have, for the first time, discovered an active leak of methane gas from the sea floor in Antarctica. It is a process that’s likely to accelerate the process of global heating.

It is the same kind of problem.

Coral Reefs are being decimated by climate change and pollution

This article offers a stark assessment of coral reef status:

The Great Barrier Reef has lost half its corals within 3 decades

The Great Barrier Reef, the world’s largest coral reef, covers nearly 133,000 square miles and is home to more than 1,500 species of fish, 411 species of hard corals and dozens of other species.”We found the number of small, medium and large corals on the Great Barrier Reef has declined by more than 50% since the 1990s,” reported co-author Terry Hughes, a distinguished professor at the ARC Centre of Excellence for Coral Reef Studies, in a statement.

Here is another article about the fish that inhabit reefs:

Ocean warming halves coral reef fish communities

Higher water temperatures linked to climate change slashed a Pacific Ocean coral reef fish community by half, according to a new study led by University of Victoria biologists that is one of the first studies to assess the direct impact of heat stress on reef fish.   

Between ocean acidification and global warming, coral reefs are doomed unless humans take drastic action to reduce the amount of carbon dioxide in the atmosphere.

No Question that Natural Disasters are getting worse due to Climate Change

This article contains a remarkable figure showing that the number of natural disasters (things like hurricanes, flooding, drought, etc.) have nearly doubled over the last 20 years.

UN warns that world risks becoming ‘uninhabitable hell’ for millions unless leaders take climate action

There has been a “staggering” rise in natural disasters over the past 20 years and the climate crisis is to blame, the United Nations said Monday.Researchers pointed to a failure of political and business leaders to take meaningful action to mitigate the impact of climatic changeand stop the planet from turning into “an uninhabitable hell for millions of people.”

Not mentioned in the article is the possibility that the earth’s entire equatorial region, and other regions like Bangledesh and even the Southern United States, could warm so much that they become uninhabitable for parts of the year. If temperatures increase enough, particularly in areas of high humidity, it may be impossible for people to go outside without overheating. From the same article:

Currently, the world is on course for a temperature increase of 3.2 degrees Celsius or more, unless industrialized nations can drastically cut their greenhouse gas emissions.

The time for a global, high-intensity, concerted effort to solve the global climate crisis is now.

Scientists Increasingly Shocked by the Loss of Sea Ice in the Arctic

Many articles over the last several weeks have been pointing out the gigantic warning that humanity is receiving from the massive loss of ice in the Arctic. It is an undeniable sign of the planet’s warming, and it is only going to get worse unless humanity takes action:

Drone footage shows extent of Arctic ice loss

“The Arctic is warming twice as fast as the rest of the world,” Dr. Enric Sala, executive producer and National Geographic’s Explorer-in-Residence said in a panel discussion following the film’s premiere on Oct. 7. “The Inuit are really the human face of global warming, and all these activities that produce all this carbon pollution are not in the Arctic region, they are mostly in a world where we are or farther south, but they are suffering the consequences.”

Climate scientists and activists responded with alarm Thursday to reporting that this is the latest date in recorded history that “the main nursery of Arctic sea ice in Siberia has yet to start freezing,” another example of the present-day consequences of human-caused global heating. According to the Guardian, “The delayed annual freeze in the Laptev Sea has been caused by freakishly protracted warmth in northern Russia and the intrusion of Atlantic waters, say climate scientists who warn of possible knock-on effects across the polar region.”

In August, Adrienne White – an ice analyst at the Canadian Ice Service who monitors the Canadian Arctic for changes in sea ice – was reviewing satellite imagery when she spotted something remarkable. The enormous Milne ice shelf, which was the last intact ice shelf in Canada and which White had studied closely before as a PhD student, was dissolving. A huge chunk larger than Manhattan, roughly 43% of the shelf, broke off in one piece. And as it collapsed into the ocean, it took with it much of the equipment her former colleagues had left there.

What a ‘sobering’ report on Arctic ice loss means for global sea levels

Will humanity do anything to solve this crisis? Will it undertake the immense global effort necessary to reverse all of the damage that has been done?
