Create a presentation about climate change
This presentation traces the history of climate change science from 19th-century discoveries of ice ages and the greenhouse effect to 20th-century evidence of human impacts, highlighting key milestone
The slide is titled "The History of Climate Change Science" and serves as a title slide for an introduction to the topic. Its subtitle describes the scientific journey beginning in the 19th century and continuing onwards.
Introduction to the Scientific Journey from the 19th Century Onwards
The presentation agenda outlines the historical progression of climate science, starting with early suspicions of ice ages and initial hypotheses about past climate cycles. It then covers the discovery of the greenhouse effect, 19th-century calculations on CO2 by pioneers like Arrhenius, and 20th-century advancements in data, models, and global evidence.
Initial scientific observations and hypotheses about past climate cycles.
Key 19th-century insights into atmospheric heat retention mechanisms.
Pioneering quantitative models by Arrhenius and contemporaries on CO2.
Evolution of climate science with data, models, and global evidence.
The slide introduces the section on "Early Discoveries in the 19th Century," highlighting the foundational developments in climate science. It focuses on initial suspicions of ice ages and natural changes in paleoclimate.
Foundations of climate science: Suspicions of ice ages and natural paleoclimate changes.
In the early 19th century, scientists first suspected the existence of ice ages, recognizing them as natural fluctuations in Earth's climate. Observations also highlighted regional variations in these climate patterns from antiquity up to the 1800s.
In 1824, French mathematician and physicist Joseph Fourier proposed that Earth's temperature rises due to the atmosphere intercepting solar radiation. This insight, featured on the slide, highlights an early understanding of atmospheric effects on planetary heat.

In 1824, Joseph Fourier proposed the greenhouse effect, suggesting Earth's atmosphere traps heat like a greenhouse, with Claude Pouillet strengthening this through experimental evidence from 1827 to 1838. Later milestones include Eunice Newton Foote's 1856 experiments demonstrating CO2's heat-trapping ability and Svante Arrhenius's 1896 calculations quantifying the impact of human CO2 emissions on global temperatures.

The slide illustrates the greenhouse effect through a sequence where sunlight freely enters Earth's atmosphere and is absorbed by the surface, causing it to warm. It then shows how the surface emits infrared radiation, which greenhouse gases trap, retaining heat and warming the planet.

Water vapor contributes 60% to the natural greenhouse effect, while CO2 levels have increased by 50% since the pre-industrial era. The warming effect of CO2 was first discovered in 1856 by Eunice Foote.

The slide contrasts natural paleoclimate changes, which have caused gradual fluctuations in Earth's climate over millennia through factors like orbital variations, volcanic activity, and solar changes—such as ice ages—without human influence. In comparison, it highlights human-induced changes since the 19th century, where activities like burning fossil fuels have rapidly elevated greenhouse gas emissions, disrupting the planet's energy balance and driving accelerated global warming beyond natural patterns.
| Natural Paleoclimate Changes | Human-Induced Changes |
|---|---|
| Earth's climate has naturally fluctuated over millennia due to orbital variations, volcanic activity, and solar changes. Examples include ice ages and regional shifts, occurring gradually without human influence. | Since the 19th century, human activities like burning fossil fuels have rapidly increased greenhouse gas emissions, disrupting Earth's energy balance and accelerating global warming beyond natural variability. |
This section header slide is titled "20th Century Onwards," focusing on developments in evidence and theories after 1900. It highlights how these advancements build upon the foundational work established in the 19th century.
Advancements in evidence and theories post-1900, building on 19th-century foundations.
Recent developments have refined theories on the primary causes of climate change, with stronger evidence confirming the significant role of human activities. Ongoing research continues to explore the impacts of climate change and potential adaptation strategies.
The conclusion slide emphasizes that history's lessons require urgent action on climate change to secure our future. It closes with a call to advocate for sustainability, urging viewers to start today.
