THE CLIMATE CHANGE
Climate change is commonly defined as a change in the weather patterns when that change it stays for an extended period of time. Climate change may refer to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions. Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, tectonics plates, and volcanic eruptions. Certain human activities have been identified as primary causes of going to a climate change, often referred to as global warming.
Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record—extending deep into the Earth's past—has been assembled, and continues to be built up, based on geological evidence from borehole temperature profiles, cores removed from deep accumulations of ice, floral and faunal records, glacial processes, stable-isotope and records of past sea levels. More recent information is provided by the instrumental record. General circulation models, based on the physical sciences, are often used in theoretical approaches to match past climate data, make future projections, and link causes and effects in climate change.
