Chapter 1: Understanding the Climate Scientists' Perspective

Recent articles suggest that climate scientists are taken aback by the swift onset of extreme weather events that endanger lives and damage property. This raises the question: are they genuinely surprised, or is there more to the story?

The doubts surrounding the astonishment of climate scientists are rooted in historical context. Fifty-six million years ago, volcanic activity led to a significant increase in atmospheric CO2, doubling it from 500 to 1000 ppm over a span of 25,000 years. This ancient event mirrors our current climate crisis, particularly the Paleocene-Eocene Thermal Maximum (PETM), which is considered the most rapid and extreme natural global warming occurrence in the last 66 million years.

The only event that might have raised CO2 levels faster was the Chicxulub asteroid impact, which eradicated the dinosaurs. Although the specifics are uncertain, some sources suggest it took approximately 100,000 years for atmospheric CO2 to revert to pre-impact levels. Given this context, the current levels exceeding 400 ppm and the projected rise to 700 ppm by 2100 indicate a long-term problem that could last for millennia—far exceeding the lifespan of any known civilization. Alarmingly, some scientists predict CO2 levels could reach 2000 ppm by 2250.

We're emitting CO2 at a rate 60 times faster than during the last comparable event 56 million years ago. Instead of 25,000 years, humanity is achieving this in about 400 years. This is concerning considering that it resulted in an increase in temperatures by 9 degrees Fahrenheit (5 degrees Celsius) and sea levels rising by 10 to 15 feet (3 to 5 meters).

NASA's data shows a steady increase in CO2 levels over the last 70 years, reaching 421 ppm as of July 2023, a steep contrast to the 280 ppm seen for the previous 6,000 years before the Industrial Revolution. This upward trend continues, despite a minor dip during the pandemic.

Consequently, extreme climate events are occurring sooner than anticipated. Scientists may struggle to find appropriate historical analogs for such rapid increases in atmospheric CO2. The swift temperature rise following the Chicxulub event may have taken a millennium, highlighting that the current rate of CO2 increase is unprecedented in Earth's 4.5 billion-year history. Humanity has become the most prolific producer of atmospheric CO2, depleting resources that took nature millions of years to create.

While individual intelligence may reach remarkable heights, collective human decision-making often reflects poor judgment. This paradox, combined with political inertia, greed, and other societal flaws, has led to a precarious situation. The advent of the steam engine and unregulated capitalism has only exacerbated these issues.

Although scientists tend to lean politically liberal, they approach their work conservatively, often downplaying alarming information to avoid public panic. The visible effects of climate change—melting glaciers, severe droughts, and heightened storm intensity—are all indicators of an accelerating crisis.

As many as 40% of insect species are declining globally, impacting the food chain that supports birds and other wildlife. Without proactive conservation efforts, many species face extinction. If humanity cannot plan for sustainability over the next 100,000 years, what hope is there for the future?

The current global population of eight billion may seem excessive to future generations, who will inherit the consequences of our actions. They will face intensified climate issues—higher winds, extreme temperatures, and rising seas—caused by our negligence.

Based on past events like the PETM, scientists anticipate a rise in sea levels of 10-15 feet and a temperature increase of 9 degrees Fahrenheit (5C), lasting for 100,000 years. The potential for CO2 levels to reach 2000 ppm poses an even graver future. How can one find optimism in such dire predictions?

Perhaps climate scientists mask their shock at the rapidity of climate change because they genuinely care about humanity's future. They understand the severity and duration of the challenges ahead, yet recognize that political systems often fail to respond effectively.

Some experts argue that the ideal world population should be around two billion, promoting sustainability alongside wildlife.

Let's draw inspiration from science fiction for potential solutions.

New technologies, such as affordable fusion energy and AI governance, could pave the way for a sustainable future. Exploring outer space could offer humanity the opportunity for expansion without the constraints present on Earth, reducing the impact of our collective mistakes.

Ultimately, without a concerted effort to reduce population and emissions, nature has its own plans, likely harsher than anything humanity can conceive. Yet, knowing human tendencies, the likelihood of effective action remains uncertain.
