Question

Since 1750, the amount of carbon dioxide in our atmosphere has increased by almost:

10%.
20%.
30%.
40%.
50%.

Answer 1

The amount of carbon dioxide in the atmosphere has increased by about 45% since 1750, mostly due to human activity such as burning fossil fuels and deforestation.

Step-by-step explanation:

Since 1750, the amount of carbon dioxide in our atmosphere has increased by almost 45%. This significant rise in CO2 concentration is primarily due to human activities, such as deforestation and the combustion of fossil fuels.

Historical data reveal that atmospheric CO2 levels have cycled between 180 and 300 parts per million (ppm) by volume in the past, but this current increase is unprecedented and is having a significant impact on global temperatures and climate patterns.
