What does the Oxford Dictionary say about it?
… a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
How about that in simple language …
Climate change is a long, decades or centuries based, change in the world’s climate, primarily a change based upon an increase in the average atmospheric temperature.
What are the effects of climate change?
Climate change is having very profound impacts on nearly every aspect of our environment, especially on the world-wide water system networks through increased flooding and ever-widening droughts. As the climate temperature rises, then air can store a higher water content, which logically then make rainfall amounts, as they move across the globe, more extreme. Rivers then wash away more soil into the oceans and lakes, creating pollution and destruction of our shores.
What are the major causes of climate change?
There are many causes of climate change, some natural while many other effects are caused by people and animals.
In fact, some sort or level of climate change has always happened on Earth, you can study this through geology and history but now, today, it is an increasing and ever-rapid rate and magnitude of climate change being observed worldwide. Due to recent human intervention, new gases in the atmosphere hold and block heat radiation from escaping our atmosphere.
The activity of people, across our globe, has through their choices and actions (since the Industrial Revolution), increased heat retention and also affected negatively surface temperatures in every nation. No one has escaped its effects. Industrial emissions as well as vehicle emissions have altered solar and infrared radiation. And lastly, deforestation has lessened the photosynthesis needed to balance the oxygen/carbon dioxide ratios PLUS as forests are destroyed the reflection of sunlight that was being absorbed and cooled is now being reflected HOT back into the atmosphere.
