What is global change climate?

Answer 1

The greenhouse effect is the way the greenhouse gases (water vapour, carbon dioxide, methane etc) in the atmosphere trap the sun's heat to keep the planet warm. This effect is supported by the water and carbon cycles of the earth, and has been going on since life began.

Global Warming is the warming of the earth during the past 200 years but especially since about 1970. Man discovered and started burning fossil fuels (coal, oil and natural gas) which releases carbon dioxide into the atmosphere that had been hidden away for millions of years. This extra CO2 is disrupting the natural greenhouse effect and is causing the enhanced greenhouse effect.

It is this enhanced, or accelerated, greenhouse effect that is responsible for global warming.

A:

Global warming, as the word has been used in recent years, is an increase in average temperature of the earth due to an increase of greenhouse gases. Greenhouse gasses are gases that trap a great deal of heat. These include CO2 and Methane. Anthropogenic global warming is a certain type of global warming caused by human production of greenhouse gases through the burning of fossil fuels and by deforestation.

The Greenhouse effect is the phenomenon of heat from the sun being trapped by greenhouse gases in Earth's atmosphere.

Answer 2

Global warming is causing global climate change. Extra greenhouse gases in the atmosphere of carbon dioxide and methane, largely, have caused an enhanced greenhouse effect. More greenhouse gases will hold more heat and this is causing global warming. The extra warming is going to change the climate.

Answer 3

Climate change is a general term for a change in climate of a long period of time, climate being the long-term weather pattern of a geographical area: temperature and precipitation averages and extremes.

When people today talk about climate change they usually refer to the present human-induced climate change caused by burning fossil fuels. This is also called global warming (scientists prefer the term climate change because even though the general pattern is a warming, some areas are expected to get colder, have more extremes in weather etc.).

By burning fossil fuels (from industry, transport, energy production etc.), greenhouse gases (GHGs) are released. Carbon dioxide is the main GHG of concern, but others are methane, nitrous oxide, water vapour, and ozone. These GHGs trap escaping energy emitted by the Earth and heat up the atmosphere, causing a general warming of the planet.

Answer 4

Global warming is the rise in the average temperature of the earth, especially in the last 200 years since the Industrial Age began. It is caused by the burning of fossil fuels, coal, oil and natural gas, for industry, transport and to generate electricity. Another cause is deforestation, which has destroyed forests all over the world that used to absorb carbon dioxide from the air and store the carbon for hundreds of years. Greenhouse gases like carbon dioxide trap the heat and warm the atmosphere.

Climate Change is caused by global warming. Climate change means changes in climate (long-term weather) which can be warming and cooling, droughts and floods, more weather events like tornadoes and hurricanes, or fewer, or more severe.

Answer 5

Earth Day is a day we celebrate earth.

Global warming is the way that the world is warming because we are burning fossil fuel.

Climate change is the way the climate is changing because of the global warming.

Answer 6

Global warming is the way the earth is warming globally, all over. This has been happening since we started burning fossil fuels (coal, oil and natural gas). The rising world temperature is making the climate change. Weather patterns that have been fairly stable for years are beginning to change more and more. This is seen in the changing weather patterns.
