Science is not conducted by consensus. Scientific theories are formulated to explain the behavior of the natural world based on observations. Over time, theories are either updated or rejected in favor of new theories based on new observations and new data. As a theory withstands the test of time and the incorporation of new knowledge its general acceptance within the scientific community grows.
So, while widespread acceptance of a theory is not, in and of itself, a validation of the theory, it can serve to reflect its robustness, particularly if that theory has been in existence for a considerable length of time and has been the subject of lengthy and diverse validation.
That carbon emissions from the industrial activities of mankind could substantially impact the global biosphere has been theorized for well over a hundred years. During that time, this theoretical premise has been subjected to continual validation as our knowledge of the natural operations of our world has grown. Technological advances have increased our observational capabilities immensely, enabling us to observe the conditions of land masses, the oceans, and the atmosphere like never before. Through these decades of observations and validation, the evidence in support of this theory has accumulated and grown stronger. As a result, it should not be surprising that acceptance of the fundamental precepts of the theory within the scientific community is near universal.
The list contains scientific organizations around the world that acknowledge the global impact of rising atmospheric greenhouse gas concentrations from human activities. While many more organizations could likely be added, the list is limited to those that have either issued a singular statement of their own or signed in agreement to a collective statement regarding the anthropogenic impact of rising emissions on global climate and the global biosphere.
All statements have been issued since 2001.
At present, there are 173 organizations on the list that span all continents outside of Antarctica.
