Evaluate the two graphs what evidence do they show regarding the changing of greenhouse gases overtime

Answer 1

The first graph shows the trend of carbon dioxide (CO2) levels in the atmosphere over the past 800,000 years. This graph indicates that there have been fluctuations in CO2 levels over this time period, but the current levels are significantly higher than they have been in at least the past 800,000 years. This suggests that human activities, such as burning fossil fuels, deforestation, and industrial processes, have contributed to an increase in CO2 levels in the atmosphere.

The second graph shows the upward trend of global average temperature over the past century. This graph demonstrates that temperatures have been steadily rising since the late 19th century, with the most significant increase occurring in the past few decades. This increase in temperature correlates with the increase in greenhouse gas emissions, particularly CO2 emissions, from human activities.

Overall, both graphs provide evidence of the changing levels of greenhouse gases, such as CO2, and their impact on global temperatures over time. The graphs suggest that human activities are contributing to the increase in greenhouse gases in the atmosphere, leading to a rise in global temperatures. This evidence highlights the importance of addressing climate change and reducing greenhouse gas emissions to mitigate the impacts of global warming.
