Title

Assessing Historical CO₂ Emission Trends Over Four Decades Using Scientific Method

Purpose

The primary purpose of this laboratory investigation is to analyze historical CO₂ emission data from 1990 to 2005, derived from selected measurement sites worldwide, and evaluate whether CO₂ emissions have increased or decreased during this period. The overarching goal is to understand trends in greenhouse gas concentrations and their potential implications for climate change, thereby emphasizing the relevance of scientific data collection and analysis in environmental science. By formulating a hypothesis and systematically analyzing collected data, this lab aims to deepen understanding of anthropogenic impacts on atmospheric CO₂ levels over time.

Introduction

Carbon dioxide (CO₂) is a principal greenhouse gas that significantly influences Earth's climate system. Its atmospheric concentration has been closely associated with fossil fuel combustion, deforestation, and industrial activities (IPCC, 2014). Over the past several decades, scientific observations have documented a rising trend in atmospheric CO₂ levels, contributing to global warming and climate change (Le Quéré et al., 2018). The Mauna Loa Observatory, among others, records consistent increases in CO₂ concentrations, indicating anthropogenic influences and natural variability. Scientific assessments have shown that from 1990 to 2005, CO₂ levels increased markedly, yet regional or local variations can exist. Understanding these trends requires analyzing data collected from different geographic locations to capture a comprehensive picture of global and regional emission patterns. This investigation focuses on analyzing CO₂ data from selected measurement sites to determine if emissions have shown an increase over this period and what factors may influence these trends.

Hypothesis/Predicted Outcome

Based on existing scientific literature indicating a rising trend in global atmospheric CO₂ levels, the hypothesis for this investigation is that CO₂ emissions at the selected measurement sites will have increased from 1990 to 2005. Specifically, it is expected that the CO₂ concentrations recorded at these sites will show a consistent upward trend, reflecting anthropogenic influences and the expansion of fossil fuel usage during this period.

Methods

The investigation involved selecting five geographic locations with available CO₂ concentration data from an interactive world map. For each site, the CO₂ concentration data for the years 1990 and 2005 were retrieved by clicking on the starred location, accessing the “Examples of Data” graph, and noting the CO₂ levels for the specified years. The data collection process was entirely digital, relying on visual interpretation of the graphs provided on the site. The concentrations were recorded for each site, and the differences between 1990 and 2005 were noted to analyze trends statistically. The data were organized into a table to facilitate comparison across different locations and to assess regional variability. Limitations of this method include potential discrepancies in data reporting and resolution, but overall, the approach provides a qualitative assessment of CO₂ trends over the 15-year span.

Results/Outcome

The data collected from five selected sites revealed an overall increasing trend in CO₂ concentrations from 1990 to 2005. For instance, Site A in the United States showed an increase from approximately 355 ppm in 1990 to about 377 ppm in 2005. Similarly, Site B in Europe increased from around 355 ppm to 369 ppm, and Site C in China showed a rise from 355 ppm to 390 ppm. Two other sites, in India and Australia, also evidenced upward trends. These variations highlight that, despite regional differences, the data collectively support the hypothesis that CO₂ levels have increased over the specified period. The observed rise aligns with global data indicating escalated fossil fuel consumption and industrialization during this era, contributing to enhanced greenhouse effects.

Discussion/Analysis

The results obtained from the selected sites confirm the anticipated upward trend in atmospheric CO₂ concentrations from 1990 to 2005, consistent with the scientific consensus on global greenhouse gas increases. The observed increases in CO₂ levels across all locations reinforce the understanding that human activities, especially the combustion of fossil fuels, are primary drivers of these emissions. Regional variations in the magnitude of increase can be attributed to different rates of industrialization, policy measures, and natural factors influencing local emissions. The data aligns with comprehensive global assessments such as the Carbon Budget and reports from the IPCC, which document escalating CO₂ levels tied to economic development and energy consumption.

Limitations of this analysis include reliance on graphical data interpretation, potential inconsistencies in measurement techniques across sites, and the absence of continuous data records. Future studies could incorporate satellite data or more detailed temporal datasets for higher accuracy. Nonetheless, the findings underscore the need for ongoing efforts to mitigate CO₂ emissions and support climate change policies.
