What is the definition of climate change?

Answer 1

Climate change has to do with a change of climate which is directly or indirectly attributed to human activity that changes the global atmosphere over the natural climate fluctuation.

Green House Effect

• The atmosphere is kept warm enough for life as we know it with a natural blanket of greenhouse gases at an average temperature of 15 degrees C.
• Due to human emissions, the blanket of greenhouse gases has become thicker and therefore trapping the heat which causes global warming.
• The biggest source of human generated greenhouse gas emissions comes from fossil fuels.

Current Evidence of Climate Change?

• Severe storms are occurring more frequently.
• Longer dry periods causing droughts.
• Heavier precipitation in certain areas.
• Increase in wildfires.
• Melting of glaciers throughout the world.
• Global increase in the sea level.
• Decline of winter weather.
• Levels of carbon dioxide are increasing at an abnormal rate.
• Ocean water is getting warmer.
• Many species of plants and animals are at risk.
• Growth in the insect population.
• Spread of tropical diseases.
• Destruction of the coral reefs around the world.

A:

Climate Change is also the condition that is being caused by Global Warming. It refers to the greenhouse gas effect where the increases in various greenhouse gases into the atmosphere, mainly carbon dioxide, are causing a warming of the earth. This warming is causing many changes in climate.

As the earth warms, scientist predict a change in the climate over crop lands, turning them into deserts, and a melting of polar ice leading to a rise in sea level and massive flooding of many low lying countries and the plains they rely on for their food.

Climate change is the temperature, precipitation or other long term weather change that permanently occurs over a period of several hundreds of years.

Climate change is the changing of weather over long periods and large geographic areas.

Climate Change is the hardcover edition of the book by Frank Chambers published by Routledge on December 13, 2002.

Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. It can be a change in the average weather or a change in the distribution of weather events around an average (for example, greater or fewer extreme weather events). Climate change may be limited to a specific region, or may occur across the whole Earth.

In recent usage, especially in the context of environmental policy, climate change usually refers to changes in modern climate. It may be qualified as anthropogenic climate change, more generally known as "global warming" or "anthropogenic global warming" (AGW).
