The main purpose of this ongoing blog will be to track planetary extreme, or record temperatures related to climate change. Any reports I see of ET’s will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ET’s (not extraterrestrials).😉
Main Topic: Recklessness on Our Environment Defined
Dear Diary. It’s always interesting to get different perspectives from experts who have been dealing with the climate/environment issue for decades. I’ve mainly posted those from Dr. Michael Mann and Dr. Katherine Hayhoe. Today it’s time to see that of Dr. Jeff Masters, who I’ve known to produce great articles on his company’s site, Weather Underground, and now through Yale Climate Communications.
It’s interesting that in the following article Jeff employs some fiction to get his point across. If you’ve ever read some of my World of Thermo material, I do this for both kids and adults, employing the “art” of allegory, which is a great communication tool.
Here is Dr. Master’s latest article:
Recklessness defined: breaking 6 of 9 planetary boundaries of safety
The author’s imaginative fictional intro opens the way for better understanding how humanity has pushed past planetary boundaries of safe living with respect to climate change, biosphere integrity, land-system change, biogeochemical flows, freshwater, and more.

Picture this …
“If you’re driving on the highway and miss your exit, you don’t step on it and keep going all the way to the ocean. You slow down and take the next exit. We’ve passed some limits noted by scientists to avoid irreversible damage to the climate, but there is still time to slow down and limit how much we suffer.”
– Susan Joy Hassol, head of the nonprofit Climate Communication.org, addressing a Communications Network 2018 conference
… and now, setting the stage, imagine this …
The trouble started at mile marker 1985. That’s when the air conditioning on your Lamborghini model RCP 8.5 megabus crapped out and the master engine fault light blinked on, a virulent red exclamation mark blazing with the dire threat of serious engine harm. You told the passengers about the problem. Ignoring the protests of a few loud-mouthed first-class passengers, you did the responsible thing and took the next exit off the expressway and pulled into a service station.
The mechanic said it was a good thing that you stopped. Your engine had overheated and melted multiple hoses, including the one circulating coolant from your air conditioning system. Despite the protests of a few obnoxious and vocal first-class passengers complaining that it would be too expensive to fix and that you should just drive on, you went ahead and agreed to the repair. While you waited, the mechanic advised you to replace your balding tires, their threads starting to show, and get a brake job, the pads dangerously worn. The road conditions ahead are more dangerous, he advised, and with forecasts of big storms moving in. He then gave you the bill, which surprisingly turned out to be 10 times less than the panicked first-class passengers claimed it would be. Despite this, they raised a big ruckus about the cost of fixing the tires and brakes, so you agreed to do only the engine fix.
You hit the road again, feeling the need for speed. Soon you find yourself cruising at 60 mph down a mountain road with blind curves and dangerous drop-offs with no guard rail. But as you whiz past mile marker 1988, you’re feeling worn out after a late night and from all the stress of the drive.
Your eyes feel droopy, and you shut them, just for a second. Mistake! Awakened by your own snoring, you suddenly recall one of your favorite brief Homer Simpson skits. You come to and find two wheels on the shoulder of the road as you careen at 70 MPH dragging a section of garden fencing post behind you.
Yet, still too fast, you swerve and avoid multiple bunnies, beavers, dodos, and frogs, which blunder in the way of your churning tires. Dang. It doesn’t help that when you pump your brakes, you hear the grinding of metal on metal, since you neglected to get that brake job the mechanic told you to get. It’s probably just as well, though, since any sudden maneuver might lead to a wipeout because of your balding tires. But shoot, that guy that you overheard last year at the Buck Lake campground said that when you start seeing the threads on your tires, you’ve still got about 3,000 miles left on them, and you’re determined to get your full money’s worth.
It’s starting to get dark now, and you flick on the headlights so that you can see a steep curve ahead. Only one headlight comes on. You smack your head. That’s right! You meant to change the burned-out bulb, but the replacement bulb is still in the glove box. Oh well. There’s still enough light to see the road, even though you forgot your glasses, and the world looks pretty blurry. No matter. You’ve invincible. You look at your unfastened seat belt. Nah. Seat belts are for wimps. Passing mile marker 2000, you gas it some more, hitting 80 mph.
Hmm, it’s getting even darker now, and there’s a huge billowing cumulonimbus cloud ahead with purplish-white lightning forking out of it. The sky has taken on an ominous green hue. Maybe if you speed up you can outrun the storm! You floor the accelerator, and skid dangerously at 90 mph around a hairpin turn, one wheel inches from a steep drop-off that plunges down over 1,000 feet. Whew! Made it. But dang, the road is taking you right into the storm. Torrential rains hammer down, accompanied by massive hailstones the size of baseballs, which shatter all of your windows. Hmm. Didn’t see that coming! The weather forecast said to expect just golf ball-sized hail.
Passing mile marker 2005, there are some blue and red flashing lights in your rearview mirror, but it’s hard to tell if it’s a cop or not, since the rear window is smashed. You figure it’s probably a snowplow working to clear all the hail off the road, which is getting very slippery now. Hmm, there are bullets whistling by the bus now, so it appears that maybe the passengers in back who are screaming about the Gaia Police are right, and they’re shooting at you now. Snowplows can’t drive at 90 mph, anyway, can they? No matter. You’ve got body armor on, though some of the poor passengers in your back seat don’t have money to afford body armor, and they’re getting shot up. You have more important things to worry about, since your cell phone is chirping. You’re expecting an important text message from your cannabis shop about that order of edibles you wanted. So, you whip out your phone and start texting. It’s getting very dark now, as you pass mile marker 2022, so you figure you better gas it to 100 mph while you can still see, like the first-class passengers are clamoring for. Or maybe you should do the responsible thing, like you did back at mile marker 1985, and take the next exit and get some repairs done? Hmm.
Figure 1. The nine planetary boundaries beyond which there is a risk of destabilization of the Earth system that would threaten human societal development, April 2022 version. Humanity had crossed out of the green “safe” space across six out of nine boundaries, and was close to crossing one other boundary (ocean acidification).

Humanity is pushing boundaries of our finite Earth in dangerous ways
When we drive a vehicle at high speed, disaster is always a split second away. An accident can occur when crossing any one of at least nine boundaries of safe operation – the engine, tires, brakes, lights, and seat belts must be functioning properly, the driver must be sober and not distracted, and the vehicle must be operated at a safe speed and not in adverse weather conditions. That careless driver in our fictional story clearly is breaking or pushing the limits of eight of nine of these boundaries.
Yet the above story is an apt analogy of the recklessness of the path humanity is pursuing as we rush toward the future – we are breaking multiple planetary boundaries of safe living on the planet that sustains us. The authors of a landmark 2015 study led by scientists with the Stockholm Resilience Institute, SRI, Planetary boundaries: Guiding human development on a changing planet, wrote of a “planetary boundaries” concept detailing nine different environmental limits to human impact on planetary ecosystems which, if crossed, could result in destabilization of the Earth system and thereby threaten human societal development.
As of 2021, according to SRI, we had already gone beyond the safe limit for five of these planetary boundaries:
• biogeochemical flows (i.e., excessive phosphorus and nitrogen pollution from fertilizer use);
• biosphere integrity (e.g., extinction rate and loss of insect pollination);
• land-system change (e.g., deforestation);
• and novel entities (e.g., pollution from plastics, heavy metals, and what are commonly referred to as “forever chemicals”).
In an April 2022 update, SRI found that a portion of a sixth planetary boundary – fresh water use – had also been crossed. In addition, in a June 2021 interview with the journal Globalizations, Dr. Will Stefan of SRI said that a seventh planetary boundary had also likely been crossed: ocean acidification (one that has been theorized as a key contributor to previous mass extinction events in geologic history). One other boundary has been too uncertain to judge: atmospheric aerosols from fine particle pollution caused by fossil fuel combustion. Yet, we are clearly pushing this boundary too, when considering that air pollution from burning fossil fuels has been blamed for 8.8 million deaths worldwide per year.
Hope for the future: from danger zone to safe zone for one boundary
The only planetary boundary of the nine that is currently agreed to be in the green “safe” zone is the one for stratospheric ozone depletion. As the opening story suggests, we crossed into the danger zone past this boundary in 1985: That’s when scientists discovered the Antarctic ozone hole, and warned that a planetary catastrophe might well ensue unless strong global action were taken. Despite industry’s warnings of severe economic harm, the nations of the world at last banded together to impose strict controls on the emissions of ozone-destroying CFCs. The fix was done at far lower cost than industry had warned of, and stratospheric ozone depletion has now receded into the green “safe” zone.
This tremendous success story proves that doom from our having crossed multiple planetary boundaries is not a certainty. Humanity can choose to do the responsible thing and stop speeding down the highway to the future while measuring progress primarily in economic terms. While following that course has led to remarkable improvements in human well-being – like the marked decrease in extreme poverty in recent decades (Figure 2 below) – that progress has come at a very steep cost. Much of the wealth we have achieved is borrowed wealth, borrowed from future generations.
Figure 2. The number of people in extreme poverty peaked from 1981-1993, and has fallen significantly since, except for a bump in 2020-2021 because of the COVID-19 pandemic.

Mother Earth has given us nine planetary credit cards to assist in our development. We’ve charged six of those nine credit cards to the hilt, and are pushing the credit limit on two others. We’ve used the oceans, land, and atmosphere as dumping grounds for our wastes, pumped Earth’s precious groundwater reserves to exhaustion, depleted her soils, razed her forests, and exterminated countless species. We are desperately trying to borrow more from Mother Earth, but there is precious little credit available.
It’s payback time, and Mother Nature is a very unforgiving lender. She abides by the laws of physics, and defaulting on just one of the loans we’ve taken out could be catastrophic. To avoid crashing civilization, we must take the next exit ramp – the one for the Paris Agreement – and work hard to keep global warming well below two degrees Celsius, by reducing carbon emissions through a rapid transition to a clean energy economy.
What is needed is a global effort similar to the proposed EU “Nature Restoration Law”, which would set legally binding targets and provide over $100 billion for nature restoration in agriculture, forests, oceans and urban areas, as reported by EurActiv. The aim of the proposal is to restore degraded ecosystems, “in particular those with the most potential to remove and store carbon, and to reduce the impact of natural disasters linked to global warming”. If economic development is done with renewable energy, forest protection, regenerative agriculture, sustainable groundwater pumping, and the like, it can increase jobs, build a healthier economy and world, and give us more of what we really care about: time to experience nature, engage in creative endeavors, and be with family and friends.
