Question

anthropogenic climate change is defined as:
climate change driven by cycles in the suns radiation
climate change due to the increase of greenhouse gas concentrations from human activities
underlying climate change that is always occurring at a background rate
climate change due to natural fluctuations the density of flowering plant
climate change driven by natural events like volcanic eruptions or changes to the earths orbit

how is the change in atmospheric carbon dioxide and temperature, like weve seen in the last 150 years, different from previous historical fluctuations?
its different because this time, we dont know whats causing the change
the change is not different
its different because the cause is increased solar radiation
its different because we havent seen any historical fluctuations in global carbon dioxide or temperature
its different because both the magnitude and the rate of change are both higher

Explanation:

Anthropogenic climate change is caused by human - related greenhouse gas emissions. In the last 150 years, the increase in atmospheric carbon dioxide and temperature is different from historical fluctuations because the magnitude and rate of change are higher due to human activities like burning fossil fuels.

Answer:

For the first question: Climate change due to the increase of greenhouse gas concentrations from human activities
For the second question: It's different because both the magnitude and the rate of change are both higher
