Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors that include oceanic processes (such as oceanic circulation), variations in solar radiation received by Earth, plate tectonics and volcanic eruptions, and human-induced alterations of the natural world; these latter effects are currently causing global warming, and "climate change" is often used to describe human-specific impacts.
Scientists actively work to understand past and future climate by using observations and theoretical models. Borehole temperature profiles, ice cores, floral and faunal records, glacial and periglacial processes, stable isotope and other sediment analyses, and sea level records serve to provide a climate record that spans the geologic past. More recent data are provided by the instrumental record. Physically based general circulation models are often used in theoretical approaches to match past climate data, make future projections, and link causes and effects in climate change.
The decreasing amount of the Arctic Ice Cap has been documented by NASA over the course of three decades.
The Ross Sea in Antarctica was declared last Friday as a protected marine bay.
Environmental officials from China tampered the air pollution results to avoid high penalties.

A "hiatus" in global warming so far this century is partly caused by natural variations in a chaotic climate and is unlikely to last, a draft United Nations report by leading climate scientists says.
As scientists and weather experts continue to be concerned with the major threat of global warming, often associated with higher temperatures than normal that can potentially lead to extreme weather events, researchers quantified how a global cooling event 116-million years ago had severe long-term ...
