If it isn’t artificial intelligence researcher Jacob Coxon proclaiming on X that superintelligence has a considerable chance of wiping out humanity, perhaps something else is keeping us up at night.
Maybe it’s the report issued on Sept. 2 by the United Nations Environmental Programme — abbreviated as UNEP — titled “Limiting Overshoot.” The details of the report paint a “bleak” and even "catastrophic” picture of climate change, according to the Boston Globe and International Business Times, respectively.
The primary message of the report is that “global temperature is set to cross 1.5°C [ 2.7°F] above pre-industrial levels, likely within the next few years.” The report goes on to list various strategies for mitigating and preventing the worst ramifications this development could bring about.
Let’s acknowledge the obvious: The following information is factual and presented by a trustworthy source. It is perfectly normal to feel anxiety and fear after reading it. However, it’s inaccurate to claim that our future is doomed to follow a downward trajectory ending in climate armageddon. The UNEP report even reiterated that “[bringing] temperatures to or below 1.5°C [ 2.7°F] by the end of the century … remains the goal.”
The point of the report isn’t to be defeatist, but rather to publicize the current standing on the issue, so the international community is incentivized to approach it differently. The U.N. is not “giving up” on solving the issue of climate change, and you shouldn’t either.
Climate change, particularly the phenomenon of global warming, has been a mainstay of U.S. government policy, popular culture and public anxiety since NASA Director James Hansen testified before the U.S. senate in 1988. The New York Times reported that he had warned, “It is time to stop waffling so much and say that the evidence is pretty strong that the greenhouse effect is here.”
While it is important to acknowledge the real danger that this phenomenon poses, it is also crucial to understand that seasoned experts on climate change, countless regulatory agencies and ordinary people have been consciously investing their energy into making the world more habitable in the face of these global threats.
As stated by the recent UNEP report, these efforts have unfortunately not been enough to hit the “1.5°C target” — the goal of limiting global temperature increase to just 1.5°C above pre-industrial levels, as outlined in the 2015 United Nations Paris Agreement. Still, they have been enough to avoid a far more apocalyptic future.
According to the Climate Action Tracker, also known as CAT, while the most ideal scenario of staying under 1.5°C has been retired, so has a much more catastrophic scenario of exceeding a 4°C [7.2°F] temperature increase by the year 2100.
The CAT Thermometer project estimates that the worst-case scenario will be a 2.6°C to 3.3°C [4.7°F to 5.9°F] temperature increase, but if countries fully implement their current climate pledges, that increase could be as low as 1.9°C [3.4°F].
This hypothetical situation, while certainly not the rosy 1.5°C scenario, would still align with the Paris Climate Change’s wider objective to “[hold] the increase in the global average temperature to … below 2°C above pre-industrial levels.”
Of course, this begs a harder question. Can human civilization actually accomplish these approachable, yet still lofty, global temperature goals? The answer is quite a hopeful one, and involves the concept of “tipping points.”
In an interview with the Guardian, Professor and Chair of Climate Change and Earth System Science Timothy Lenton at the University of Exeter defined a tipping point as “where change becomes self-propelling within a system,” meaning that it will become rapid and strengthen at an accelerating rate.
With relation to climate change, there are several negative tipping points that either have been crossed or that we are dangerously close to, such as the Greenland ice sheet shrinking at an accelerating rate, or the unprecedented bleaching and die-off of coral reefs, Lenton says.
But there are plenty of positive tipping points humans have either reached, or are highly expected to come to pass, with the help of climate-focused innovations and initiatives. A report issued by Green Futures Solutions, which builds off of Lenton’s work, has claimed to have identified “51 environmental solutions that can trigger rapid and transformable change to repair our planet within the next five years.”
Green Futures Solutions determines clean energy as the “highest-leverage” transition, claiming that the global shift to clean energy could trigger a “massive” cascade of environmental progress. Clean energy technology includes solar power, which Lenton identified as having “exponential growth of installed generated capacity,” and electric vehicles, whose proliferation in Chinese and European markets signals a wider global trend in electrifying transportation.
In an article on the Green Futures Solutions report, Matthew Pearce of the Guardian explained that this international transition to clean energy could help reduce air pollution, cut waste emissions and revive oceans.
Meeting the previously stated temperature increase goals, even the least ideal, will require “rapid, collective and global action” according to the aforementioned UNEP report — but it is possible, and, going by the information above, very much underway.
Our planet will be facing upcoming challenges, and our approach to limiting the ramifications of climate change has been anything but a perfect trajectory, but the situation is not hopeless. We still have a significant say in our future, even if it is the future of a changing world.
