Please note: All members are strongly recommended to read the very detailed 2025 and beyond forecast and the 10 most important facts about climate change before reading any of the pages in our Members-Only sections. This will provide you with a basic understanding of the severity and seriousness of what we will soon collectively face in the near future.

In this era of global warming-aggravated extreme weather events, any rational individual or business will want to avoid investing in real estate in a high-risk climate change location that repeated climate catastrophes will regularly (or permanently) disrupt. Climate catastrophes have many faces, such as the hurricanes of Harvey, Irma, and Maria, or the wildfires in Northern California that burned over 6,000 structures, droughts in the West, or storm and sea level flooding occurring worldwide. 

The illustration below shows only a few of the consequences of climate change and global warming.

It is not just extreme weather events like heatwaves, heat domes, droughts, sea level rise, wildfires, hurricanes, flooding, rain bombs, extreme winds tornadoes, (Derechos), dust storms, wildfire smoke storms, and freak cold spells and non-seasonal weather and those severe costs that will determine the best future locations to buy or sell real estate for personal use or investment or to conduct or build new businesses. Unlike many of our climate-denying politicians, smart real estate investors and business leaders now understand that they must plan their future real estate investments and business operations to minimize the 20 worst consequences of escalating global warming. Smart real estate investors and businessmen have also noted that our military and intelligence agencies have repeatedly warned that escalating global warming has become the greatest disrupter, threat, and risk multiplier of the 21st century. 

Because global warming has become the great disruptor of the 21st century, the minimal due diligence criteria and 7 new rules for evaluating where and when to plan, buy or sell personal or corporate real estate have now become:

1.) Do not buy or own property in areas near forests due to the increasing danger of wildfires and smoke from escalating temperatures, droughts, and atmospheric heat turbulences (today's ever-increasing heat creates higher future winds that can fan and rapidly spread fires).

2.) Do not buy or own property or businesses or create new businesses in areas projected for global warming-intensified extended drought areas because of life-stifling heat, predicted massive water shortages, and, as mentioned above, wildfires. These droughts and intense heatwaves will increasingly slow and disrupt normal commerce.

3. Do not buy or own property in any millennial floodplains. Millennial floodplains refer to the newly calculated floodplain maps that many insurance agencies are rapidly creating and using to replace outdated or no longer applicable 100-year-old floodplain maps. We are now facing superstorms of all kinds, as well as other severe weather events that used to occur only once every thousand years, now occurring numerous times every decade due to the escalating global warming emergency.

These thousand-year millennial superstorms also flood previously uncharted areas near rivers and lakes. This new shift to using the new millennial floodplain maps also means that insurance companies will be significantly raising rates for many of their new millennial map-expanded floodplain customers and canceling others altogether. The release of these new insurance company millennial floodplain maps will also have a radical and sudden impact on real estate property values once they become widely public knowledge, as they soon will.

4.) Do not buy or own property or businesses or create new businesses in areas projected to have regular global warming-caused or aggravated “rain bombing” where a month’s or week’s worth of rain falls in a single day or several days and seriously floods inland areas many of which have never previously flooded in this way. Rain bombs can disrupt normal commerce and transportation in an area for days to weeks, and even months.

5.) Do not buy or own property less than 25 feet above sea level if you are considering coastal areas. This new real estate investment rule requires a bit of technical explanation. The carbon level in our atmosphere, measured in parts per million, is the single best and most accurate way to determine if we are progressing in reducing or slowing global warming. As of March 2024, we are at 427 parts per million (ppm) of carbon, with an average annual increase of more than 3 ppm. As you can see in the carbon ppm graph below, things are worsening at an exponential rate, according to the trend line.

At 421 carbon ppm, the stability of the bellwether West Antarctic ice sheet has already been breached and is now irreversible.

At the 425-450 ppm carbon threshold, which we are expected to reach in about 4-10 years, we will continue to cross more of the 11 critical global warming tipping points within the various systems and subsystems of the overall climate, but now at an even faster rate.

Moreover, once we cross the 500 ppm carbon threshold, projected around 2040 (approximately 23 years or less from now), all ice and all glaciers on Earth will undergo complete meltdown, and the oceans will eventually rise by 70 meters (230 feet). This has happened repeatedly in Earth's geological history whenever carbon levels crossed the critical atmospheric carbon threshold of 500 ppm.

When we recalculate sea level rise, which will now include crossing one or more of the 11 critical global warming tipping points, these new calculations and allowances predict a global sea level rise of as much as 3 meters (10 feet) by 2050. This is not the publicly promoted three-foot sea-level rise by 2100 put out by the UN’s Intergovernmental Panel on Climate Change. Unfortunately, the IPCC has repeatedly underestimated the impacts of global warming by 20 to 40% and has utterly failed to properly include calculations for crossing any of the significant global warming tipping points now in play.

This means that if you are planning to purchase any piece of real estate near sea level, you want it to be safe and the property to be viable past at least 2050; for a minimum level of sea level safety, the property would need to be 10 feet above sea level, plus the height of the local king tides and storm surges normal to that area, plus an extra safety measure to ensure your real estate investment will be around for more than 50 years. (It is important to note that several times in Earth’s geologic history, sea levels have risen by 10 feet or more in as little as two decades after significant climatic tipping points were crossed.)

The following graph will help illustrate the future problems associated with our currently rising atmospheric carbon dioxide and carbon ppm levels, as seen from a perspective of hundreds of thousands of years. As you can see in the last part of the graph, which has been broken out to illustrate our last 1,000 years more clearly, it clearly shows that we have entered a whole new range of increased atmospheric carbon security risk and threat exposure.

For hundreds of thousands of years, through various Ice Age cycles, we stayed below about 275 carbon ppmv. However, since the beginning of our extensive use of fossil fuels, starting with the Industrial Revolution, atmospheric carbon levels and average global temperatures have risen to levels unseen for millions of years.

If you currently own or are considering buying any real estate or businesses not above 13 feet above sea level near a coastal area, don't unless you plan to flip the property within a very short period and long before 2050. Sea level rise will impose massive and rushed infrastructure rebuilding costs for relocating or rebuilding electrical, sewage, harbors, seawalls, bridges, highways, and water systems in all coastal areas less than 13 feet above sea level before 2050. Residents and businesses who don't want to spend the retrofitting cash will significantly drop their sale prices to cash out and move to safer areas. Military bases, particularly naval bases located in areas less than 13 feet above sea level, will be particularly hard hit, as they will be unable to perform their normal protection, resupply, and repair functions due to regular and escalating flooding. 

6.) Whenever possible, seek to locate significant real estate and business investments in areas near or above the 45th parallel north or near or below the 45th parallel south. In computer models, these areas are projected to be the safest if they have adequate water and decent soils.

Ever-increasing heat, security issues, and other global warming consequences like rain bombs, drought, massive crop failures, and water shortages will continue to create a massive “climagee” (climate refugee) migration from the ever-expanding global warming crisis to unsafe zones below the 45th parallel north.

These climagee migrations are predicted to begin in earnest from about 2027 through 2040 as the general population realizes they have been mislead about how bad global warming is and how bad it will get. These migrations will involve first hundreds of millions, and then billions of individuals with few or no resources as the catastrophic reality of escalating and out-of-control global warming wreaks havoc below the 45th parallel north and above the 45th parallel south, and it becomes undeniable to the majority of the world’s population. It is highly doubtful that real estate businesses or personal investments in zones that will be inundated with hundreds of millions of desperate climate refugees will be able to maintain their value or continue operating as usual.

7.) Soaring flooding, fire, crop, and storm insurance prices, and the inability to get mortgage insurance because of increasing refusal of insurers to offer insurance and global warming unsafe zones. As more people recognize global warming location as the new big factor in property valuation and business investment viability, and as more insurance companies raise rates and deny coverage in more global warming unsafe zones, real estate values will, on average, begin losing or gaining about 1% to 3% of their value each year depending upon whether you're in a global warming safe or unsafe location. (In many areas of Houston, Texas, after its last big storm, real estate values have dropped as much as 7% in one year.)

Property values will soar or crash much faster in some regions deemed safe or unsafe due to global warming. Despite the difficulty of predicting exactly how much property values will rise or fall, with few exceptions, more people and insurance companies recognize that the more an area is perceived as unsafe due to global warming, the faster real estate property values will continue to drop, and vice versa.

8. A new bonus rule: The world's largest real estate price crash is coming. If you have not done so already, please take the time to read about one very hazardous glacier collapse that will near-instantly radically change the price of coastal real estate around the world. It is also genuinely critical to your immediate and future well-being.

This soon-collapsing massive glacier will give you a powerful glimpse into the global economic, social, and political turmoil that just this one major collapsing glacier will create as coastal real estate prices plummet.)

Not only do you have to be aware of the above rules, but today's real estate investors must also be aware of our rapidly deteriorating climate change conditions. Current projections indicate that the consequences of climate change and global warming will become significantly worse (25 to 40% worse) from 2025 to 2031 due to past crossed climate tipping points, new crossed climate tipping points, and climate feedbacks. (Please click here to read all about how and why this will happen, as described in the first tipping point on this page.) 

The escalating global warming emergency has created new rules for the intelligent location or relocation of future personal or business real estate investments. Failure to include these minimal due diligence criteria in business real estate purchase evaluations will most likely expose those evaluators and companies to gross negligence lawsuits from angry shareholders or investors who experience the value of their investments or properties ravaged by currently known global warming consequences and established prediction patterns. 

Additionally, many in real estate and related industries are also beginning to take note of escalating global warming’s total broader economic impacts of on their nation’s GDP (gross domestic product) and, conversely, on their own expansion plans, future risks, markets, and bottom lines. The current predictions for how high the total annual global warming-related costs to nations around the world will rise range from 5% of total gross domestic product (in the Stern report) to 10% of the total GDP (from the book Climate Shock) to up to 30% of the total GDP in escalating global warming’s final phases as described in the Climageddon Scenario in the new book Climageddon, The Global Warming Emergency and How to Survive It.  It is not unreasonable to also project that similar GDP cost/loss annual operating percentages will eventually apply to the net incomes of those purchasing real estate in high-risk zones for global warming --- if they can still obtain insurance.

In conclusion, few knowledgeable individuals or businesses will want to live, work, buy homes, conduct business, or be part of businesses in any of the rapidly expanding global warming-unsafe zones. Global warming is quickly evolving the time-tested real estate value adage of “location, location, location” to “always purchase your real estate or business investments in global warming-safe locations.” 

If you are still investing in unsafe areas vulnerable to global warming, exit before you start incurring huge losses, as more and more people and businesses recognize the impact of our escalating and now irreversible global warming on their real estate, businesses, future, and finances.

Welcome to our brave new world of real estate and business investment, where chains of the 20 worst global warming-aggravated consequences are increasingly frequent, severe, extensive, and costly, and will continue to erode your bottom lines. This is because one thing you can rely on with the escalating global warming emergency is that the 20 worst global warming consequences will regularly and consistently increase in frequency, severity, and scale.

(The stability of real estate prices in many countries is already being affected by the climate. This rising instability is in part due to the severe climate consequence prediction and remedial solution errors of the IPCC of the UN. Click here to read about how those serious prediction and remedy errors could affect future forecasts in this area.)
