What is the theory behind why Earth's climate is changing?
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.

How quickly parts of the Earth's climate are changing in response to added greenhouse gases and what's forecast for decades ahead is a mixed bag, a federal advisory council says in a report out Tuesday. Man-made carbon dioxide is generally thought to produce global warming. However, in a recent article entitled Does Carbon Dioxide Drive Global Warming?. I presented several major reasons why carbon dioxide is probably not the primary cause. 1 But if carbon dioxide is not the cause, then what is?Evidence is accumulating that cosmic rays associated with fluctuations in the sun's electromagnetic field may be what drives global warming.igure 1 shows a 400-year record of the monthly number of sunspots. Note the low number of sunspots in the period from 1645 to 1715. This period is called the Maunder Minimum 4 and coincides with the Little Ice Age, the coldest period of temperature during the last 1,000 years. Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average conditions (i.e., more or fewer extreme weather events).or the study of past climate change, see paleoclimatology. For temperatures on the longest time scales, see geologic temperature record. Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). A global warming conspiracy theory invokes claims that scientific consensus on global warming is based on conspiracies to produce false data or suppress dissent.It is one of a number of tactics used in climate change denial to legitimise political global warming controversy disputing this consensus. global warming conspiracy theory invokes claims that scientific consensus on global warming is based on conspiracies to produce false data or suppress dissent.

This period is called the Maunder Minimum 4 and coincides with the Little Ice Age, the coldest period of temperature during the last 1,000 years.For many years, climatologists attempted to correlate the number of sunspots with various climate variables, including temperature and precipitation.By the 1980s these attempts were determined to be futile, because the percentage change in solar heating was found to be insufficient to explain the variations.igure 1 shows a 400-year record of the monthly number of sunspots.

There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels.rack Earth's vital signs from space and fly along with NASA's Earth-observing satellites in an interactive 3D visualization.

Warm near the equator and cold at the poles, our planet is able to support a variety of living things because of its diverse regional climates.

Anything that affects the amount of energy being absorbed from the Sun, or the amount being radiated by the Earth-the planet's energy balance-may produce long-or short-term cooling or warming.Natural or 'forcing'.here are many factors that could cause a change in our climate.
