What Is Global warming?

Global warming is a long-term rise in the average temperature of the Earth’s climate system; an aspect of climate change shown by temperature measurements and by multiple effects of the warming. Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect, a warming of Earth’s surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases.

What are the causes of global warming?

Greenhouse gases trap heat radiating from Earth to space. This heat, in the form of infrared radiation, gets absorbed and emitted by these gases in the planet’s atmosphere warming the lower atmosphere and the surface.

What are the causes and effects of global warming?

Global warming is projected to have a number of effects on the oceans. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.

How does global warming affect us?

As the climate warms, it changes the nature of global rainfall, evaporation, snow, stream flow and other factors that affect water supply and quality. Specific impacts include: Warmer water temperatures affect water quality and accelerate water pollution.

What greenhouse gases cause global warming?

A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect. The primary greenhouse gases in Earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone.

What is global climate change definition?

The term “climate change” is often used to refer specifically to anthropogenic climate change (also known as global warming). Anthropogenic climate change is caused by human activity, as opposed to changes in climate that may have resulted as part of Earth’s natural processes.

What are some examples of climate change?

Examples include changes in solar output and volcanism. Human activities can also change earth’s climate, and are presently driving climate change through global warming.

What are the physical impacts of climate change?

Global warming is projected to have a number of effects on the oceans. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.

What are the physical impacts of climate change?

How does greenhouse effect global warming?
The greenhouse effect is the process by which radiation from a planet’s atmosphere warms the planet’s surface to a temperature above what it would be without its atmosphere. If a planet’s atmosphere contains radiatively active gases (i.e., greenhouse gases) they will radiate energy in all directions.
