A change in global or regional climate patterns,in particular a change apperant from mid and late 20 century ownwards and attributed largely to the increase level of atmospheric carbon dioxide producd by the use of fossil fuels.

What Is Climate Change?
Climate change is a change in the usual weather found in a place. This could be a change in how much rain a place usually gets in a year. Or it could be a change in a place's usual temperature for a month or season.
Climate change is also a change in Earth's climate. This could be a change in Earth's usual temperature. Or it could be a change in where rain and snow usually fall on Earth.
Weather can change in just a few hours. Climate takes hundreds or even millions of years to change.
Is Earth's Climate Changing?
Earth's climate is always changing. There have been times when Earth's climate has been warmer than it is now. There have been times when it has been cooler. These times can last thousands or millions of years.
People who study Earth see that Earth's climate is getting warmer. Earth's temperature has gone up about one degree Fahrenheit in the last 100 years. This may not seem like much. But small changes in Earth's temperature can have big effects.
Some effects are already happening. Warming of Earth's climate has caused some snow and ice to melt. The warming also has caused oceans to rise. And it has changed the timing of when certain plants grow.
What Is Causing Earth's Climate to Change?
Many things can cause climate to change all on its own. Earth's distance from the sun can change. The sun can send out more or less energy. Oceans can change. When a volcano erupts, it can change our climate.
Most scientists say that humans can change climate too. People drive cars. People heat and cool their houses. People cook food. All those things take energy. One way we get energy is by burning coal, oil and gas. Burning these things puts gases into the air. The gases cause the air to heat up. This can change the climate of a place. It also can change Earth's climate.
What Might Happen to Earth's Climate
Scientists think that Earth's temperature will keep going up for the next 100 years. This would cause more snow and ice to melt. Oceans would rise higher. Some places would get hotter. Other places might have colder winters with more snow. Some places might get more rain. Other places might get less rain. Some places might have stronger hurricanes.
The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.
