Organization Position The climate is changing with 20th Century and the beginning of the 21st the warmest period in the entire global instrumental temperature record from the mid-19th century. Cause is not definitively attributed yet.

| Description
|
Climate change is a normal part of the Earth’s natural variability, which is related to interactions among the atmosphere, ocean, and land, as well as changes in the amount of solar radiation reaching the earth. The geologic record includes significant evidence for large-scale climate changes in Earth’s past.

NOAA No Position on Human Cause
NOAA has not taken a firm position as an organization as to whether Global Warming is Human Caused or anthropogenic they neither deny nor accept the premise defering to the IPCC stating Certain naturally occurring gases, such as carbon dioxide (CO2) and water vapor (H2O), trap heat in the atmosphere causing a greenhouse effect. Burning of fossil fuels, like oil, coal, and natural gas is adding CO2 to the atmosphere. The current level is the highest in the past 650,000 years. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change concludes, that most of the observed increase in the globally averaged temperature since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.
