Carbon dioxide atmosphere absorbs and stores the energy near the earth's surface when incoming solar radiation is reflected back to the space. If there was no carbon dioxide then there would no absorption of solar energy and hence the temperature of earth's surface would be less than the present level. So, the correct answer is 'Less than the present level'.

Global warming occurs when carbon dioxide and other air pollutants called the greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface.

Global warming refers to the increase in the average temperature of earth due to an excessive amount of greenhouse gases namely CO$ _2$, CH$ _4$ etc. It can be controlled by reducing deforestation. A high plant cover utilizes the major amount of CO$ _2$ from the air. Also another method of control is cutting down the use of fossil fuels which otherwise emits greenhouse gases like CO$ _2$, N$ _2$O etc.

Global warming refers to an increase in the overall temperature of the atmosphere due to accumulation of greenhouse gases that trap long wave radiations. Due to this, the water cycle is affected because the cloud formation is erroneous. This causes disturbed pattern of rainfall. Other effects of global warming are shown in the following diagram:

Sublimation is the process where a substance changes directly from a solid to a gas without passing through the liquid phase. Ice turning directly into water vapor is a classic example of this.

Scientific consensus attributes the current rapid melting of glaciers primarily to human-induced global warming, which increases atmospheric and ocean temperatures.

Global warming is predicted to have widespread and severe adverse effects on ecosystems, including habitat loss, species extinction, and disrupted migration patterns.

Human activities, such as burning fossil fuels and deforestation, are the primary drivers of the increased greenhouse gas emissions that cause global warming.
