Progress Made in Addressing Climate Change: Gaining Momentum for a Sustainable Future
According to Katharine Hayhoe, chief scientist of The Nature Conservancy and a distinguished professor of climate science at Texas Tech University, humanity’s journey in tackling climate change can be likened to scaling the world’s tallest mountain. While the ultimate goal may seem distant, significant strides have already been taken.
Renewable energy sources like wind and solar power have become the most cost-effective options for electricity generation. Heat pumps are increasingly prevalent in discussions about heating and cooling systems, and electric cars have become mainstream.
On Earth Day 2024, the commitment to climate-friendly initiatives receives a boost as the Biden administration announces grants worth $7 billion. These funds aim to provide solar power to over 900,000 homes in low-income and disadvantaged communities. The anticipated outcome is annual savings exceeding $350 million in electricity costs, equating to approximately $400 per household, over the next 25 years.
Hayhoe’s analogy resonates: It may feel like an arduous ascent, but looking back reveals the substantial progress made. Even Al Gore, the former senator and vice president who has long warned about global warming since 1981, expresses a sense of cautious optimism. While acknowledging the need for faster action, Gore believes that momentum is building, bringing us closer to effectively addressing the climate crisis.

Triumphs in Environmental Challenges: Examples of Progress
Over the past 50 years, humanity has achieved remarkable victories in addressing significant environmental challenges. These successes serve as inspiring examples of our capacity to overcome seemingly insurmountable obstacles.
One such instance is the story of DDT, a pesticide hailed as a marvel in combating mosquitoes and pests when it was introduced in the 1940s. However, in the late 1950s, scientists made the connection between DDT and the decline of bird populations due to thinning eggshells, which led to the crushing of their own offspring. The ban on DDT in 1972 resulted in a remarkable recovery, and by 2007, bald eagles had rebounded to the extent that they were removed from the Endangered Species list.
Another environmental concern involved the depletion of the ozone layer, which shields us from harmful ultraviolet radiation. In the early 1980s, scientists discovered a hole in this crucial protective layer. Recognizing the severity of the problem, nations worldwide signed the Montreal Protocol, committing to phase out chlorofluorocarbons responsible for the hole. Today, the ozone layer is self-repairing, projected to return to its 1980 levels by 2060.
Moreover, acid rain, caused by burning coal containing sulfur, emerged as a destructive force in the 1950s, devastating forests and aquatic life across vast regions in the northeastern United States. Growing public awareness in the 1970s prompted action, and the Clean Air Act of 1990 played a vital role in reducing sulfur emissions, leading to a decline in acid rain levels.
These achievements demonstrate that concerted efforts and effective policies can bring about positive change, reinforcing our ability to address pressing environmental challenges.
Promising Outlook: Projected Peak in Global CO2 Emissions
When reflecting on the concerning state of carbon dioxide (CO2) levels in our atmosphere, it is crucial to consider historical context. CO2 concentrations reached a record high last year, standing at 420 parts per million—the highest in human history. This significant increase from pre-Industrial Revolution levels of 280 parts per million has contributed to a rise in global temperatures by approximately 2 degrees Celsius.
However, amidst this alarming reality, there is a noteworthy development that often goes unnoticed but carries great hope. Experts, including the International Energy Agency, suggest that global CO2 emissions are likely to reach their peak next year, and certainly no later than 2030, based on current policy trajectories.
This projection implies that 2023 was probably the year with the highest greenhouse gas emissions ever recorded, and from this point forward, emissions are expected to decline steadily.
While this does not compensate for the substantial volume of CO2 that has been released into the Earth’s atmosphere since the mid-1700s, it represents an important milestone. It demonstrates that the transition towards cleaner and more sustainable energy sources is well underway.
The Global Shift to Clean Energy: Unstoppable and Inevitable
As affirmed by Fatih Birol, the Executive Director of the International Energy Agency (IEA), the transition to clean energy is an unstoppable force unfolding worldwide. It is no longer a matter of “if” this shift will happen, but rather a question of “how soon.”
However, it is important to acknowledge that current emission levels exceed the necessary threshold by one-third to limit global warming to 2.7 degrees Celsius. Significant reductions in global per capita emissions are still required. Despite this, progress is being made, often unnoticed by the general public, as highlighted by Hannah Ritchie.
Clean energy has achieved a remarkable milestone
It has become the cheapest form of energy available. Solar and wind power, in particular, have experienced a rapid decline in costs, surpassing the expectations of many climate experts. The progress made in the past decade is substantial, with solar, wind, and battery power now being significantly less expensive than coal, nuclear, and natural gas.
According to Lazard, an analysis by a financial advisory firm, the unsubsidized cost of wind power has plummeted by 66% since 2009, while unsubsidized solar costs have fallen by an impressive 84%. This dramatic change in affordability has fundamentally shifted the energy landscape, altering the pace at which low-carbon technologies are adopted.
Hannah Ritchie, author of “Not the End of the World: How We Can Be the First Generation to Build a Sustainable Planet,” emphasizes that the cost transformation in clean energy has been striking. She acknowledges that a few years ago, she held a pessimistic outlook due to the high costs associated with renewable energy. However, the current trajectory of decreasing costs has dispelled her concerns.
This shift towards affordable clean energy is not limited to the United States but is a global phenomenon. China, although still the world’s largest carbon emitter and continuing to construct coal-fired power plants, is rapidly embracing renewables. In 2023, new solar, wind, and hydroelectric power installations in China accounted for 59% of the world’s new renewable energy capacity, as reported by S&P Global.
The International Energy Agency predicts that demand for oil, coal, and gas will peak by 2030, primarily driven by the increasing adoption of electric vehicles worldwide and China’s continued shift towards wind and solar power. While this prediction falls short of meeting the Paris Agreement’s goal to limit global temperature rise, it signifies a significant step in the right direction.
Katharine Hayhoe, a climate scientist, highlights the progress made in tackling climate change. The projected temperature increase by the end of the century has decreased from the initial estimates of 7.2 to 9 degrees to a more optimistic prediction of a 4.8-degree warmer world. With each step taken towards sustainable solutions, this trajectory continues to improve.
These positive developments in clean energy affordability and adoption showcase the potential for a more sustainable future and provide hope for effectively addressing the climate crisis.
A Glimmer of Hope
Amidst the challenges posed by climate change, there is reason for hope. Hannah Ritchie emphasizes that addressing climate change is not as insurmountable as it may appear. Solutions to climate change often have overlapping benefits, meaning that efforts to tackle one problem can yield positive outcomes for multiple issues simultaneously.
However, it can be difficult to stay focused on this hopeful perspective. Climate change deniers, who have been active for decades, have now adopted a new tactic known as “doomerism,” proclaiming that it is too late to make a difference and that there is no hope. This narrative of hopelessness can paralyze individuals, preventing them from taking action.
Katharine Hayhoe acknowledges that some people become overwhelmed by the magnitude of climate change and succumb to unproductive doomerism. It is important to strike a balance between recognizing the urgency of the issue and maintaining a positive outlook that motivates action.
Al Gore, a prominent figure in the climate movement, shares his awe at the progress humanity has made. The statistics speak for themselves: in 2023, 80% of new electricity generation installed worldwide came from solar and wind power, and 20% of new vehicles sold globally were electric vehicles. These advancements exceed expectations and demonstrate the potential for rapid change.
Gore recalls the words of economist Rudy Dornbusch, who famously said that things often take longer than anticipated but then happen faster than imagined. This sentiment captures the dynamic nature of progress and the potential for transformative change.
While the challenges of climate change remain, maintaining a hopeful perspective, recognizing the interconnectedness of solutions, and understanding the speed at which change can occur are crucial elements in driving effective action.
