Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.

Multiple lines of scientific evidence show that the climate system is warming.

Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century, and in paleoclimate proxy records over a thousand years.

Climate change denial, or global warming denial, is part of the global warming controversy.

It involves denial, dismissal, unwarranted doubt or contrarian views which strongly depart from the scientific opinion on climate change, including the extent to which it is caused by humans, its impacts on nature and human society, or the potential of adaptation to global warming by human actions.

Some deniers do endorse the term, but others often prefer the term climate change skepticism whereas scientists think it "inappropriate to allow those who deny [anthropogenic global warming] to don the mantle of skeptics"; in effect, the two terms form a continuous, overlapping range of views, and generally have the same characteristics: both reject, to a greater or lesser extent, mainstream scientific opinion on climate change.

Climate change denial can also be implicit, when individuals or social groups accept the science but fail to come to terms with it or to translate their acceptance into action.

Several social science studies have analyzed these positions as forms of denialism.

The Sun is the star at the center of the Solar System.

It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process.

years ago from the gravitational collapse of matter within a region of a large molecular cloud.

Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System.

The central mass became so hot and dense that it eventually initiated nuclear fusion in its core.

It is thought that almost all stars form by this process.

A planet is an astronomical body orbiting a star or stellar remnant that.

is massive enough to be rounded by its own gravity,

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
