This section header slide, titled "Early Suspicions of Climate Change," introduces section 02 of the presentation. It highlights that suspicions of ice ages and paleoclimate changes first emerged in the early 19th century.
02
Ice ages and paleoclimate changes first suspected in the early 19th century.
In the 19th century, Joseph Fourier first proposed the greenhouse effect in 1824, laying early groundwork for understanding atmospheric warming. This was followed by Claude Pouillet strengthening the evidence between 1827 and 1838, and Eunice Newton Foote demonstrating CO2's warming potential in 1856.
The timeline slide outlines key milestones in the early scientific understanding of the greenhouse effect and human-induced climate change. Starting with Joseph Fourier's 1824 proposal that Earth's atmosphere traps heat like a greenhouse, it progresses through Eunice Newton Foote's 1856 experiments demonstrating CO2's heat absorption, Svante Arrhenius's 1896 calculations of CO2 doubling causing 5-6°C warming, and accumulating 20th-century evidence confirming global warming.
1824: Fourier Proposes Greenhouse Effect Joseph Fourier suggests Earth's atmosphere traps heat like a greenhouse. 1856: Foote Demonstrates CO2 Heating Eunice Newton Foote experiments show CO2 absorbs heat from sunlight. 1896: Arrhenius Quantifies Human CO2 Impact Svante Arrhenius calculates that doubling CO2 could warm Earth by 5-6°C. 20th Century: Accumulating Evidence of Climate Change Throughout the 20th century, scientists gather data confirming human-induced global warming.
In 1856, pioneering American scientist Eunice Newton Foote conducted an experiment demonstrating that carbonic acid gas (CO2) absorbs and retains solar heat more effectively than other substances. Her quote, "'The highest effect of the sun's rays I have found to be in the case of carbonic acid gas,'" laid the groundwork for understanding the greenhouse effect.

The slide illustrates the greenhouse effect through a visual diagram, showing how sunlight freely enters Earth's atmosphere and is absorbed by the planet, which then radiates heat back out. Greenhouse gases trap this outgoing infrared radiation, leading to natural warming that is enhanced by human activities.

The slide "Impactful Calculations" highlights key climate science milestones, including the prediction of a 5-6°C global temperature rise from doubling atmospheric CO2 levels. It also notes Svante Arrhenius's 1896 calculation as the first climate model demonstrating human impact on emissions and an early forecast of CO2's critical role in warming.

Paleoclimate science highlights natural fluctuations in Earth's climate over millennia, driven by factors like orbital changes, volcanic activity, and solar variations, resulting in long-term cycles such as ice ages and warmer interglacials. In contrast, modern science attributes rapid, unprecedented warming since the late 19th century to human activities, including fossil fuel use, deforestation, and industry, which have elevated greenhouse gas levels and disrupted the planet's energy balance.
| Paleoclimate: Natural Variations | Modern Science: Human Influence |
|---|---|
| Earth's climate has naturally fluctuated over millennia due to orbital changes, volcanic activity, and solar variations, leading to ice ages and warmer interglacials. These cycles occur over tens of thousands of years, driven by non-human factors. | Since the late 19th century, human activities have rapidly increased greenhouse gas emissions from fossil fuels, deforestation, and industry, disrupting Earth's energy balance and causing unprecedented warming at a pace far exceeding natural changes. |
This section header slide is titled "20th Century and Beyond," marking a key phase in the history of climate science. Its subtitle highlights the growing scientific consensus supported by evidence of human-induced climate change.
Scientific consensus grows with evidence of anthropogenic climate change.
The conclusion slide, titled "Lessons from History," highlights how scientific insights from Fourier to the present day underscore the urgent need for action on emissions to combat climate change. It features a subtitle urging immediate steps to protect our planet.
From Fourier to today, science shows urgent need for action on emissions to mitigate climate change.
