There are just 4 global warming deadlines and tipping points to never forget because if we miss or cross them...
humanity and civilization will most likely cease within our lifetimes!
That is a strong statement, but we can prove every bit of it to you in the links on this page.
But, first you need to know what the four deadlines and tipping points are:
The 2025 "last chance" prevention deadline and tipping point:
Because we have wasted 35 years with ineffective global warming regulation, if we do not hit our critical and last chance 2025 radical global fossil fuel reduction targets as described on this page, we go over the climate cliff and the global warming tipping point that will create a downward sliding slope so steep that it is highly improbable we will be able to recover from it until long after we cross the unbearable near-extinction and then final extinction level tipping points described further below.
Here's another way of describing why the above 2025 global fossil fuel reduction targets are so important to achieve. If we do not engage in anything less than the greatest mass mobilization of resources in human history directed toward radically cutting fossil fuel use to hit the critical 2025 targets described above, we will without a doubt cross what is known as our "last chance" carbon 425-450 ppm climate cliff. It is called the last chance climate cliff because once we go over this carbon 425 to 450 climate cliff we will not be able to stop ourselves from going over other far worse global warming tipping points.
The following is a graph showing carbon in our atmosphere in parts per million (ppm.) Currently, we are now averaging about 3 additional carbon ppm per year. As you can see below after 21 global conferences on reducing global warming, we are failing horribly at reducing atmospheric carbon ppm which directly causes global warming from fossil field burning.
If we continue only to the carbon 425 ppm climate cliff and tipping point level, in about 6 years or less we can expect an eventual increase in average global temperature of about 2.2°-2.7° Celsius (4°-4.9° Fahrenheit) from preindustrial levels. At the 2.2°-2.7°, Celsius increased temperature levels from preindustrial levels, millions and millions of people will starve to death and be forced to either migrate or die.
Worse yet, once we hit the 2.2°-2.7° Celsius temperature increase level the heat producing momentum within our climate systems for all of the previous carbon that we have put into the atmosphere, we will rapidly push the temperature even higher. When we cross the carbon 425 carbon ppm climate cliff tipping point, we will have also reached the key threshold transition level where we will slide quickly down the slippery slopes and continue near uncontrollably to 3°, 4°, 5°, and 6° Celsius average global temperature increases (5.4°, 7.2°, 9°, and 10.8° Fahrenheit.)
These much sooner arriving higher temperatures than we are being told by our governments of 3°, 4°, 5°, and 6° Celsius will be due our continuing to add more fossil fuel carbon to the atmosphere but also from the crossing additional global warming tipping points and triggering other positive feedback loops and points of no return within the many systems and subsystems of the global climate.
The 2029 "migrate or die" deadline and tipping point:
If we miss our last chance 2025 global fossil fuel reduction targets, and if you live in a global warming unsafe zone, you will need to migrate before this date. Near or by about 2029 real estate prices will crash in global warming high-risk areas and they will soar in the few remaining global warming low-risk areas. Nations in the global warming low-risk areas will either be closing their borders or making immigration so restrictive that few individuals will still be able to migrate.

The 2038-2042 deadline and "near-extinction" tipping point, where ALLice on earth begins melting:
Crossing the climate cliff of carbon 425 ppm unfailingly sets us up to rapidly cross with the next near-extinction tipping point level of carbon 500 ppm where the temperature will eventually increase to 4°C. At a 4°C temperature increase above preindustrial levels, all ice on earth will melt and organized society cannot exist!
Crossing the carbon 500 ppm threshold has, in fact, happened repeatedly in Earth's geological history. When this has occurred, the sea level inevitably rose to the 70 meters (230 feet) range. At our current annual carbon ppm emission rates of an additional 3 ppm, we will reach this catastrophic carbon 500 ppm range in as little as 20-25 more years about 2038-2042.
If we cross that critical tipping point by passing the atmospheric carbon level of 500 parts per million (ppm), our average global temperature will eventually, but quickly soar to 4°C (7.2 degrees Fahrenheit). At 4°C, a large portion of humanity (hundreds of millions to billions) will die of starvation (or die and suffer from increased heat's 19 other related consequences) and, governments and society will collapse in most areas of the world between the 35th parallel north and the 35th parallel south.
Even though it will take many centuries for the seas to rise the full 230 feet, there will still be shocking sea level rise spurts within those centuries where the sea level rise up to 10 feet or more in just a few decades as it also has done repeatedly in Earth's past.
Take a moment to visualize the seas eventually but steadily rising 230 feet and what this will mean to our coastal cities, our national borders and the generations that follow us. Take a moment to visualize the ever-increasing massive worldwide crop failures because of the ever-increasing heat and the consequent mass suffering of slow starvation as we approach and pass the carbon 500 ppm level.
Take a moment to let the following sink in once again. Anything at or above a 4°Celcius increase in average global temperature would be incompatible with an organized global society and would be beyond adaptation!
This temperature and carbon ppm level would also virtually guarantee we will hit carbon 600 ppm. When we cross the carbon 500 ppm tipping point we cross a steeper even more slippery slope and we will quickly reach the carbon 600 ppm extinction level tipping point within another 25-30 years (as soon as 2063-2072 or earlier.)
When we cross carbon 500 ppm level, we also will greatly accelerate the process of crossing more global warming tipping points. This will once again further spike the average global temperature. If we are really really lucky carbon 500 ppm might be pushed back to between 2042-2067.
The 2063-2072 or earlier deadline and "final extinction" tipping point
Once we cross the carbon 500 ppm near-extinction tipping point, it is nearly certain that we will also soon cross the carbon 600 ppm final extinction tipping point not long after that. Crossing the carbon 600 ppm level will result in raising the average global temperature to 5°C (9 degrees Fahrenheit) and bring about massive methane clathrate releases from ocean coastal shelves as it has done before in the Paleocene–Eocene Thermal Maximum56 million years ago, and most notably the Permian–Triassic extinction event, when up to 96% of all marine species became extinct, 252 million years ago.
Please click here to watch a short video that brilliantly explains the global extinction process once we start releasing vast amounts of methane clathrate from our coastal shelves. Although methane is being released all over the world in and greater and greater amounts, new research shows that we most likely begin the massive methane release processes once we reach 5°C and, By 6°C, it is in full bloom.
Because methane, when released is 86 times more potent than carbon as a temperature increasing greenhouse gas, it' massive release will rapidly spike up the average global temperatures once again.
The following is a methane graph (found at https://www.methanelevels.org)in which you can see how total atmospheric methane levels from all sources have skyrocketed particularly during the last 50 years.
If it continues to rise from there toward the carbon 600 ppm final tipping point and an average global temperature of 5°C, it will eventually bring about the extinction of most if not all of humanity (about 70-90%) and the end of civilization as we know it in the final phases of what is called the Climageddon Scenario.
While even slowing down our crossing the carbon 600 ppm extinction tipping point will be a Herculean task of massive global cooperation and mobilization, the probability that we can at least temporarily, slow and delay some of the other of the 20 worst global warming consequences is still reasonable, but more importantly radically slowing down fossil fuel use will allow us more time to get prepared for the many other consequences we can no longer avoid.)
As you can see the probability that we will cross the carbon 600 ppm extinction tipping point is high. Additionally, the final window of opportunity to prevent crossing the carbon 600 ppm extinction tipping point will close by 2025 if we have not made the radical and immediate radical fossil fuel cuts necessary. This is because of the:
a. temperature momentum already "baked" into the climate system (the existing carbon 411 ppm level already in the atmosphere,)
b. the additional 3 or more carbon particles per million we continue to add to the atmosphere each year (as we continue failing to adequately reverse our fossil fuel use,) and
c. The additional global warming tipping points we will continue to cross at an even faster rate if we miss our 2025 fossil fuel reduction targets.
At 5°C which will occur once we hit carbon 600 ppm and above, a large portion of humanity (70-90% or more,) will die of starvation because of the devastating effect that increased heat will have on crop failures or from global warming's other 19 worst consequences) and, economies, governments, and societies will collapse in many areas of the world between the high-risk 45th parallel north and the 45th parallel south. As we reach the carbon 500 ppm and carbon 600 ppm tipping point levels, we will also cross into the later and most dangerous later phases (4 and 5) of the 6-phase Climageddon Scenario climate model. (We strongly recommend that at some point after you finish this document you also read about the 6 phases of the Climageddon Scenario here. It more specifically describes the deadlines, timetables, and phase by phase consequences of your global warming future if we miss our 2025 targets.)
Take a moment and think about the bitter reality that at the carbon 600 ppm tipping point (which can occur as soon as 2063-2072, or possibly even earlier,) where we trigger the final processes that will bring about the extinction of as much as 70 to 90% of humanity if not more.
Long before we reach the carbon 600 ppm level tipping point level, civilization will begin collapsing in earnest and as we get close to this level the unlucky survivors will enter into an ecological and climate hell and a new social dark age that will make the survivors of the following centuries curse us and wish they were dead.
