Sentences with phrase «natural drivers of climate change»

It is a bit surprising that scientists attempt to write a supposedly «serious» paper estimating degree of the climate's natural against the anthropogenic change with this state of knowledge: The nature and origin of the AMO is uncertain, and it remains unknown whether it represents a persistent periodic driver in the climate system, or merely a transient feature.
Indeed, the American Association of Petroleum Geologists (AAPG), an international organisation of more than 30,000 Earth scientists, has formally rejected the view that anthropogenic factors are the main drivers of global warming, stressing: «The earth's climate is constantly changing owing to natural variability in earth processes.
