Twenty fifty is the official date for net zero emissions. According to the experts, it is the last chance to stop a catastrophic rise in temperature. The leading source for climate change science, the U.N. IPCC, says so. Corporations run commercials helpfully informing the public that net zero is a top priority. Few can outdo Delta Air Lines, which promises compliance using “a fully sustainable long-haul aircraft [that] has yet to be invented.”
The urgency is palpable and the science compelling. Humanity itself is at risk without net zero CO2 and non-CO2 emissions.
Politically, 2050 is the ideal climate date because it is close enough to justify immediate action, and just far enough as to be unprovable for climate disaster.
For a science so settled and a date so specific, there must exist a wealth of data scientifically supporting the hypothesis that 25 years from now marks a deadline and turning point for the Earth’s future.
An A.I. query provides the answer:
The target year 2050 for achieving carbon neutrality is primarily driven by scientific consensus and international agreements aimed at limiting global warming to 1.5°C above pre-industrial levels. The Intergovernmental Panel on Climate Change (IPCC) and the Paris Agreement outline that reaching net-zero CO2 emissions by 2050 is crucial to avoiding catastrophic climate impacts.
A.I. is correct that the IPCC and the signatories of the Paris Agreement are the parties responsible for promoting 2050 net zero. But who exactly are these organizations, and do they deserve our trust?
The IPCC is a political body consisting of 195 member-governments, charged with providing assessments in support of the U.N. Framework Convention on Climate Change. In theory, the IPCC mandate is to collect the best available climate science. The IPCC expressly commits that its “reports should be neutral with respect to policy.” And by its own admission, “the IPCC does not conduct its own research.” Its role is to summarize the objective science.
The signatories to the Paris Agreement are likewise 195 nations convened under the auspices of the U.N. But unlike the IPCC, the Paris Agreement signatories make no pretense to being a scientific body, and indeed, no one is confused on this point. The signatories are a political body and the Paris Agreement a purely political document.
With an overlapping membership, it should come as no surprise that the two organizations coordinate their efforts. In the process, the IPCC has become the loudest and most strident advocate for existential change in human activity. In the latest IPCC report, deepening red gradient shadings convey that the Earth is a looming inferno.
According to the IPCC, the danger of imminent collapse due to rising CO2 and non-CO2 emissions, particularly methane, requires immediate action. Humanity must downsize and restructure the global economy, including, in their modest terminology, “governments, private sector, and civil society.” Everyone is responsible, and everyone must contribute.
Not only must GDP be lowered, but the world must immediately and drastically curtail fossil fuels; limit global agriculture output based on emissions, not feeding the world; spend and redistribute upwards of $125 trillion; rely on expensive, unreliable, discredited solar and wind for global power needs; and virtually ignore nuclear power, all the while “prioritizing equity, climate justice, social justice, inclusion and just transition processes.” To make the math work, governments and the private sector must implement on a global scale yet-to-exist carbon capture technologies, of unknown cost and consequence.
There is no imputation here that climate science is not real. It is the political choices of the IPCC at issue, specifically the 2023 Sixth Assessment’s Summary for Policymakers, as opposed to the physical scientists reporting as Working Group 1. As summarized by scientist Roger Pielke, “it is not within the IPCC’s mandate to call for action or to implore urgency.”
The IPCC task is to vet and summarize thousands of complex models and scientific papers produced annually. In each instance, a climate model incorporates assumptions not easily aggregated. The IPCC solution groups the models into five arbitrary scenarios based on forecasted warming in 2100. At no point does the IPCC ever declare one set of scenarios more likely than another. Indeed, as aggregators, they have no scientific basis for making any such assertion. In these scenarios, 2050 does not exist as a scientifically significant year. It is simply a point on the curve connecting the current temperature to the 2100 end point.
To get to 2050, and urgency, the IPCC needs to import the political findings of the Paris Agreement.
In 2015, the Paris Agreement signatories reviewed the then most current IPCC report, the 5th Assessment. These 195 government actors arbitrarily concluded that “well below 2 degrees Celsius” of warming was the maximum threshold the Earth could survive. Nothing in the IPCC 5th Assessment supports the “well below 2 degree warming” as a scientific consensus. No IPCC evidence identifies a scientific threshold for global warming beyond which the Earth tips into collapse. Especially relevant, the signatories to the Paris Agreement in no manner highlighted 2050 as a year of special climate meaning, nor would it matter, scientifically speaking, if they had. Following the 5th Assessment, the Paris Agreement target date is merely a “long-term temperature goal,” with one reference to “the second half” of the century.
The Paris Agreement signatories went farther, deciding by imperial fiat that the temperature goal needed a guardrail, the now infamous, endlessly repeated 1.5-degree-warming “limit.” In popular parlance, many, many people will swear that 1.5 degrees of warming is a scientifically valid statement of the limit to global warming, beyond which climate catastrophe ensues.
As important to note, all IPCC warming targets, including the Paris Agreement, start from the pre-industrial period 1850–1900. According to the IPCC, 1.1 degrees of warming has already occurred, meaning the Paris Agreement target at present is a mere 0.4 degrees over 75 years to the IPCC 2100 model date. This equates to an imperceptible 0.005 degrees of annual warming — hardly the stuff of headlines and catastrophic collapse. And nothing compared to the 10 degrees of warming observed in the Earth’s last interglacial warm period in Siberia some 115,000 to 130,000 years ago.
It needs to be said as loudly as possible. The 1.5-degree climate tipping limit has no basis in any finding of the IPCC. It is the arbitrary finding of 195 political actors, in defense of the non-scientific “well below 2 degree” catastrophe, magically transported by the IPCC from 2100 to 2050.
How does the IPCC move the climate clock back 50 years, in violation of its 2100 science? By intentional sleight of hand, the IPCC provides a science answer to a policy question. How much CO2 can be emitted before the 1.5-degree target is breached? The sole source of the 1.5 degrees is the Paris Agreement.
Pro-IPCC climate scientists confirm that the global warming limit, whether it be 1.5 degrees from the Paris Agreement or some other number, is based solely on “value judgments and choice,” not “climate science.” (See page 7 chart.) The IPCC would have readers believe the exact opposite: that the global warming limit is scientifically determined, and those who disagree are “science deniers.” It is a deception of massive consequence.
Twenty fifty, as it turns out, is a long con between 195 governments and the IPCC.
As part of his Day One actions, President Trump needs to, once again, remove the U.S. from the Paris Agreement and disavow the overtly political IPCC Sixth Assessment Summary for Policymakers. The IPCC global prescription is not scientific, and it most certainly is not benign.
