Answer
In 2009, North America had the highest CO₂ emissions with 6,594 million metric tons, while Africa had the lowest CO₂ emissions with 1,056 million metric tons.
Step 2

Answer
To find X, we use the formula:
X=Total emissionsAgriculture emissions×100
From the data, Agriculture emissions in Europe are 7.9% of the total 4,720 million metric tons. Thus,
X=1007.9×4720=372.88 million metric tons
Therefore, X is 7.9%.

Answer
Energy production (excluding transport) relies heavily on fossil fuels such as coal, oil, and natural gas, which emit significant CO₂ when burned. This sector often involves industrial processes and electricity generation that contribute greatly to emissions, resulting in higher output compared to other sectors.

Answer
Changes in Temperature: The greenhouse effect can lead to increased temperatures, affecting crop yields and potentially reducing agricultural productivity.
Altered Precipitation Patterns: Changes in precipitation can result in droughts or flooding, impacting water availability for irrigation and altering growing seasons.
