The Illusion of Overshoot
Record-breaking fossil fuel production, soaring greenhouse gas emissions, and extreme temperatures are becoming the new norm. We’re ignoring the urgent climate crisis, believing that future technologies will rescue us. However, the reality is that overshooting the 1.5°C target could lead to catastrophic consequences.
During the 2023 climate negotiations in Dubai, the conference president proclaimed a goal of limiting warming to 1.5°C. Yet, his plans included a massive increase in oil and gas production. Such contradictory actions highlight the disconnect between climate promises and actions.
Many net zero pledges are based on the illusion that we can avoid dangerous climate change without actual emission reductions. This means drastic cuts in greenhouse gas emissions from industry, transport, energy, and food systems are necessary.
One glaring example is Amazon, which set a 2040 net zero target. Despite this, their emissions increased by 40% over four years, leading to their removal from the UN Science Based Targets initiative.
Flaws in the Paris Agreement
The Paris Agreement, celebrated for setting the 1.5°C goal, is now showing its limitations. It focuses on temperature targets rather than the root cause: the build-up of carbon dioxide in the atmosphere. This focus on temperature allows for misleading solutions like solar geoengineering.
Climate change is dangerous due to the extreme weather it brings. Solar geoengineering might lower temperatures but increases human interference in the climate system. It’s akin to turning on the air conditioning in response to a house fire.
We initially argued that net zero was a dangerous trap. Now, as climate policy increasingly revolves around the concept of overshoot, the impacts on food, water security, and human health are becoming intolerable.
Key issues with the Paris Agreement include:
- Focusing on temperature rather than carbon reduction
- Encouraging unrealistic reliance on future technologies
- Failing to enforce immediate, drastic emission cuts
2023: A Year of Alarming Signals
In early 2023, experts predicted the year would be slightly warmer but not record-breaking. By year’s end, it was the warmest year ever recorded, surpassing the 1.5°C target. This rapid warming indicates we might be missing key factors in our climate models.
Extreme weather events in 2023 serve as a preview of the suffering increased global warming will bring. A World Economic Forum report projects 14 million deaths and $12.5 trillion in losses by 2050 due to climate change.
Understanding why global temperatures have spiked recently is complex. Natural processes and human impacts on the Earth’s carbon cycle play significant roles.
Natural carbon sinks, such as forests and oceans, have historically absorbed much of our carbon emissions. However, there is evidence that these sinks are becoming less effective, complicating efforts to reduce global warming.
Science Fiction Solutions
The proposed solutions to climate change often sound like science fiction. Technologies like Direct Air Capture and sulphate aerosol injection are risky and unproven. The reality is that these solutions are being considered because of the failure of current climate policies.
As climate impacts worsen, we will face more frequent and severe natural disasters. This will lead to increased costs for adaptation and compensation for those most affected.
Instead of reducing fossil fuel use, we’re betting on untested technologies to manage the crisis. Some of these technologies might need to operate for centuries to avoid the worst consequences of overshoot.
While some advocate for carbon removal and geoengineering in good faith, the effectiveness of these technologies is uncertain. They may divert attention from the immediate need to reduce fossil fuel consumption.
The Reality of Climate Tipping Points
Even if we deploy carbon removal and geoengineering technologies, there’s a major issue with overshooting 1.5°C: tipping points. These critical thresholds can lead to irreversible changes in the climate system.
Recent research on tipping points, including contributions from over 200 academics, shows that overshooting is an extraordinarily risky gamble. Some tipping points, like the collapse of ocean currents, could cause global havoc.
Beyond 1.5°C, we risk losing vital ecosystems like coral reefs and ice sheets. The Greenland ice sheet, for instance, is losing ice at an alarming rate, contributing to sea level rise.
The message from tipping point research is clear: further warming accelerates us towards catastrophe. It’s crucial to act now to prevent reaching these dangerous thresholds.

Great article! We need more awareness about the urgency of real emission cuts. Keep it up!

Why are we still increasing fossil fuel production if it’s so harmful? Doesn’t make sense!

Thank you for shedding light on the flaws of the Paris Agreement. This information is crucial.

Future tech often sounds like a sci-fi movie, but are there any realistic solutions? 😅
dylanzenith
Is there any hope left if our natural carbon sinks are becoming less effective?

So frustrating to see big corporations like Amazon failing on their climate promises!

Wow, this is really eye-opening. What actions can we take on a personal level to help? 🌱
