Given the information in the graph, what conclusion can you make concerning the relationship between climate change (increasing global temperatures) and the amount of carbon dioxide released into the atmosphere by land ecosystems? Explain, using information from the graph to support your explanation.
Explain why you agree or disagree with
at least 90% the world's climate
scientists that (a) climate change is
happening now, (b) human activities
play an important role in this climate
change, and (c) human actions can slow
down the rate of climate change and
avert or delay its projected harmful
environmental, health, and economic
effects.

Explain, using information from the graph to support your explanation.arrow_forwardHuman lifestyle choices currently release greenhouse gases into the atmosphere at higher rates than what occurs naturally. When greenhouse gases like carbon dioxide, methane, and nitrous oxide accumulate they trap heat. As a result of this trapped heat, temperatures on Earth's surface are changing Figure 1 - Greenhouse Gas Emissions by Humans Choice and the Greenhouse Gases Emitted as a Result Which of these ideas would be the best course of action for decreasing land temperatures? 1. Phase-out agricultural production, since that sector, produces the largest amounts of methane and nitrous oxide. 2. Decrease land use and biomass burning, because this sector produces all three major greenhouse gases. 3. increase the number of waste disposal and treatment plants because they do not release carbon dioxide 4. Develop alternative energy sources to decrease the amount of carbon dioxide released as a result of power stationsarrow_forward
- feedback (below), can affect climate. An Q3.27. Over long time scales the increase in atmospheric CO₂ concentrations increases the greenhouse effect and causes temperatures to rise. As ocean temperatures rise, the solubility of CO2 decreases. As a result, CO₂ is released from the oceans to the atmosphere, strengthening the greenhouse effect and causing temperatures to rise further.
