The correct answer is: rising sea level over a period of time, increasing carbon dioxide in the atmosphere, and increasing greenhouse gas concentration in air.

The correct option that is an effect of global warming is "rising sea level over a period of time". To understand why this is the case, let's break down the options and explain how to identify the correct answer.

Option 1: "rising sea level over a period of time"
Global warming leads to the melting of glaciers and ice caps, which causes an increase in the volume of water in the oceans. As a result, the sea level gradually rises over time. This process has been observed and documented by scientists, making it a well-known effect of global warming.

Option 2: "increasing carbon dioxide in the atmosphere"
One of the main contributors to global warming is the increase in greenhouse gases, particularly carbon dioxide, in the Earth's atmosphere. This is primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes. While this is a significant consequence of global warming, it may not directly be considered an effect in the context of the question.

Option 3: "increasing greenhouse gas concentration in air"
Similar to the previous option, the increasing concentration of greenhouse gases, including carbon dioxide and other gases like methane, contributes to the warming of the Earth's atmosphere. However, this is more of a cause rather than a direct effect of global warming.

Option 4: "changing seasons every year"
While global warming does have an impact on climate patterns and may alter the timing and intensity of seasons, the concept of "changing seasons every year" is not a precise description of the effects of global warming. This option is more general and does not specifically address the impacts of global warming.

To summarize, the correct answer is "rising sea level over a period of time" (option 1), as it accurately describes one of the observable consequences of global warming.
