The scorching summer of 1988, plagued by a devastating drought in the American Midwest, provided a stark backdrop for a pivotal moment in the history of climate change awareness. On June 23rd, amidst record-breaking temperatures, Dr. James Hansen, a leading climate scientist at NASA, testified before the U.S. Senate. His message was clear and unequivocal: the greenhouse effect, or what we now commonly refer to as climate change, was no longer a theoretical concern for the distant future. It was happening now.
Hansen's testimony, along with that of other prominent scientists, marked a watershed moment in the public discourse surrounding climate change. While not universally accepted at the time, their warnings resonated with some lawmakers, who recognized the urgent need for action to address the growing threat of global warming. The New York Times' coverage of the event highlighted the gravity of the situation and helped to raise awareness among the broader public.
Over the following decades, the scientific consensus on climate change solidified, and public opinion gradually shifted. Today, a majority of Americans acknowledge the reality of climate change, though the historical context surrounding this understanding may not be widely known. The legacy of that sweltering summer in 1988, and the courageous scientists who spoke out, continues to shape our understanding of and response to the climate crisis we face today.
In anticipation of the anniversary of James Hansen's groundbreaking testimony on climate change, curators at the Smithsonian's National Museum of American History delved into their collections to trace the evolution of this critical issue.
Their discoveries reveal a complex interplay of forces at work in the history of climate change. The museum's holdings showcase a long history of American innovation, including both technologies that could mitigate the effects of climate change and those that have exacerbated it.
Some artifacts poignantly illustrate how we've arrived at a critical juncture in the climate crisis. As record-breaking temperatures devastate ecosystems and endanger lives worldwide, other objects shed light on scientists' tireless efforts to comprehend and address the impending threat to humanity.

Forests play a crucial role in combating climate change, making their destruction a significant setback in our efforts to mitigate its effects.
Humans have long utilized trees for various purposes, aided by tools like axes. However, as population and consumerism have grown, deforestation has accelerated dramatically. The consequences are far-reaching, ranging from immediate habitat loss to long-term disruptions in climate regulation. Trees absorb and store vast amounts of carbon dioxide, a major greenhouse gas, thus stabilizing our climate.
While deforestation isn't a new phenomenon, the limitations of axes historically slowed the rate of timber harvesting. Today, advanced technology enables rapid clearing of ancient forests, but the root cause lies in our insatiable demand for convenience and comfort. Agriculture, driven by this demand, is a leading factor in deforestation. Addressing this issue requires a fundamental shift in global production systems, particularly those responsible for our everyday food and products. - Tony C. Perry, curator of environmental history, Division of Work and Industry.

In the 19th century, lighting transitioned from candles to whale oil, then camphene, and eventually to kerosene. Despite appearing smokeless, kerosene lamps released greenhouse gases into the atmosphere.
Oil lamps, like the one patented by John Irwin in 1862, transformed society. Bright and affordable artificial light revolutionized our perception of time, work, leisure, and consumption. The demand for kerosene, derived from petroleum, surged, leading to increased drilling in the U.S. and abroad. U.S. domestic crude oil production experienced exponential growth. By the 1870s, kerosene had become a major American export.
Although electric lights eventually replaced kerosene lamps in the late 1800s, the reliance on petroleum persisted, as gasoline fueled even greater demand, perpetuating our dependence on fossil fuels. - Peter Liebhold, emeritus curator, Division of Work and Industry.
Medicine and science apparatus for administering nitrous oxide and other anesthetic gases, circa 1890
Nitrous oxide, commonly known as laughing gas, has been a staple in dentistry since the 19th century, easing countless patients' anxieties. However, this benefit comes with a hefty environmental price. Nitrous oxide is a far more potent greenhouse gas than carbon dioxide, and its effects linger in the atmosphere for extended periods.
This ornate gasometer, patented in 1884 by dentist Amos Long, exemplifies the historical use of nitrous oxide in dental practices. Its intricate design belies the harmful impact of this gas on our planet. While primarily used for dental procedures, nitrous oxide also found its way into obstetrics to alleviate pain during childbirth.
Today, the healthcare industry, including the use of anesthetics like nitrous oxide, contributes significantly to greenhouse gas emissions in the United States. Surprisingly, few people are aware of the connection between their comfortable dental experiences and the ongoing climate crisis. - Alexandra M.

Photosynthometer, circa 1905
This pear-shaped plant chamber and graduated cylinder, once a common sight in college labs, allowed students to measure the exchange of gases during photosynthesis. By 1905, when botanist William Francis Ganong described this apparatus, the basic inputs and outputs of photosynthesis were understood, but the underlying biological mechanism remained a mystery.
The photosynthometer reflects the growing influence of chemistry on botanical studies. It took decades of interdisciplinary research to fully understand the carbon pathway in photosynthesis, just one piece of the intricate carbon cycle that continuously moves carbon between the atmosphere and Earth. – Kristen Frederick-Frost, curator of modern science, Division of Medicine and Science.

Gasoline pump, 1911
The gasoline pump, over its century-long history, has reflected the evolving relationship between consumers, the oil industry, government, and the environment. Initially designed for gas lighting systems by Gilbert & Barker in 1865, the company later adapted to the growing demand for gasoline due to the rise of automobiles. In 1910, they introduced hand-operated pumps, marking the birth of modern gas stations, and by 1911, they were producing pumps capable of measuring the amount of gasoline dispensed.
The future of gas pumps in the context of climate change is uncertain. The popularity of electric vehicles, with their need for charging stations rather than gasoline, and the increasing use of public transportation could potentially reduce the reliance on individually operated vehicles and, consequently, gas pumps. - P.L.

“Swift’s Premium Corned Beef” crate label, 1920s
The United Nations has consistently highlighted that greenhouse gas emissions from animal agriculture are comparable to those from transportation, with the cattle industry accounting for over half of the livestock sector's climate impact. This significant carbon footprint can be traced back to the mid-20th century, when beef grading was adopted and industrial feedlots gained prominence, initially in the U.S. and then globally.
A label like this "Swift's Premium Corned Beef" crate label symbolizes the early stages of graded beef marketing. In the late 1920s, meatpackers like Swift & Company began grading and labeling beef with their own brands, eventually leading to the dominance of the USDA's national grading system. This system favored grain-fed cattle over grass-fed, driving producers towards intensive corn-feeding practices in industrial feedlots. Consequently, the cattle population exploded, causing a dramatic increase in carbon emissions by the 1970s. - Abeer Saha, curator, Division of Work and Industry.

"Old Betsy," Caterpillar's first mass-produced diesel engine model, introduced in 1930, revolutionized the heavy machinery industry. Its 86.8 horsepower and ability to run on various fuels made it a popular choice for construction and agricultural equipment. Manufacturers favored diesel over gasoline due to its increased efficiency.
However, the environmental impact of diesel engines is a major concern today. They account for over 25% of carbon dioxide emissions in the U.S. transportation sector. While diesel engines can burn more efficiently than gasoline engines, potentially releasing less carbon dioxide per distance traveled, the comparison is complex and varies depending on the specific vehicle and design. Critically, diesel engines are also significant contributors to nitrogen oxide and particulate matter emissions, which have detrimental effects on human health and the climate. - A.S.

Climate change is often associated with rising atmospheric temperatures, leading to a cascade of negative impacts. However, the oceans, covering the majority of our planet, play a crucial role in heat absorption and distribution, influencing the climate system significantly. While weather records provide valuable information, they offer only a partial understanding of the intricate climate puzzle.
Since the 17th century, scientists have recognized the importance of oceans in climate regulation. However, studying the vast and deep ocean waters has been a formidable challenge. The slow circulation of cold, deep waters carrying equatorial warmth to polar regions makes even slight temperature variations highly significant. To overcome the difficulties of measuring temperature at great depths, innovative solutions were developed.
This reversing thermometer, commonly used from 1890 to 1970, showcases several ingenious features. To protect the thermometer bulb from immense water pressure, it was encased in a sturdy outer tube. Moreover, the reversing mechanism ensured that the temperature reading taken at the desired depth remained preserved until the instrument was retrieved.
The reversing principle, introduced by Negretti & Zambra in 1874, involved a sliding weight ("messenger") that triggered the reversal of the thermometer and also released another messenger to activate the next thermometer in a series. Additionally, a Nansen bottle attached to the frame collected water samples at different depths for further analysis. - Roger Sherman, curator of modern physics, Division of Medicine and Science.

At the Mauna Loa Observatory in Hawaii, over 11,000 feet above sea level, a hiss marked the opening of a glass flask. The resulting vacuum was filled with a sample of North Pacific air before being resealed and sent back to the Scripps Institution of Oceanography. This routine journey, repeated over many years, contributed to a crucial atmospheric carbon dioxide dataset spanning from 1958 onwards.
Scientist Charles David Keeling initially observed a seasonal variation in the data, correlating with plant growth. However, over time, a more ominous trend emerged: a continuous rise in carbon dioxide levels due to fossil fuel consumption. This led to the creation of the Keeling Curve, an iconic symbol in climate science that raised alarm about global warming. James Hansen, in a 2005 New York Times obituary for Keeling, succinctly captured the significance of his work: “He altered our perspectives about the degree to which the earth can absorb the human assault.” - K.F.

The history of climate change is full of unexpected twists. One example is the surprising role the petroleum industry played in making solar panels a viable energy source. This Solarex "Solar Energizer" actually powered equipment on an offshore oil rig.
The scientific foundation for solar panels dates back to the 19th century, but it wasn't until 1954 that Bell Telephone Laboratories developed a practical solar cell. These were initially used to power remote communication equipment where conventional power lines were impractical.
Fast forward to the 1980s, and the oil industry began investing in solar panel research to address challenges in their own operations. Offshore, solar panels offered a cost-effective alternative to heavy batteries for powering equipment, while onshore, they provided small currents to protect oil well casings from corrosion.
The oil industry's adoption of solar technology not only reduced their own expenses but also demonstrated the real-world viability of solar panels beyond space applications. This spurred further development and cost reduction, ultimately leading to the widespread use of solar panels we see today, contributing to a shift away from fossil fuels. - H.W.

The challenge of climate change presents a stark irony: society expects scientists and engineers to resolve a crisis they arguably contributed to creating.
Historically, cities have been established near bodies of water due to their benefits, such as water supply and transportation. However, this proximity also increases vulnerability to flooding. Climate change exacerbates this issue by causing rising sea levels and intensifying weather events, making storms rainier, windier, and more damaging.
The 2005 Hurricane Katrina disaster in New Orleans exemplifies this challenge. Flooding occurred due to a combination of factors, including an engineering flaw in the flood wall design. While the faulty infrastructure was replaced with a stronger one, the question remains: Can engineering ultimately outpace the escalating forces of nature in the future? - P.L.

The devastating impact of Hurricane Maria on Puerto Rico in 2017 reveals a potent combination of climate change and a history of colonialism. The storm's destructive force, magnified by unsustainable energy systems and weakened infrastructure due to past exploitation, resulted in widespread suffering and loss.
Puerto Rico's colonial past, spanning 500 years, left the island vulnerable to the hurricane's wrath. The storm's immense size and power caused over 4,000 deaths, countless injuries, and lasting trauma.
The island's precarious infrastructure, a legacy of industrialization and a debt crisis, exacerbated the damage. Homes designed to rely on air conditioning or natural ventilation were easily breached, leaving residents exposed to relentless mosquito attacks. Environmentalist Fernando Silva recognized the resulting sleep deprivation and led a community effort to revive the lost art of crafting mosquito nets, providing relief to affected communities.

For centuries, physical currency like coins and banknotes has been the primary medium of exchange, relying on environmentally taxing processes like metal mining. Digital currencies, such as Bitcoin, initially seem like a greener alternative. However, the digital mining required for many cryptocurrencies consumes vast amounts of electricity, primarily generated from fossil fuels, raising concerns about their environmental sustainability.
Bitcoin, the most popular cryptocurrency, has become a cultural symbol representing a rejection of traditional systems. The Bitcoin ring, a unique take on the engagement ring, exemplifies this sentiment. It allows the wearer to invest in Bitcoin instead of a diamond, with a 3D-printed QR code linking to the blockchain and displaying the amount of Bitcoin owned. Although seemingly more environmentally friendly than traditional diamond mining, the Bitcoin ring's environmental impact is hidden in the energy-intensive mining process. - Ellen Feingold, curator of the national numismatic collection, Division of Work and Industry.
