"Believe it or not, very little research has ever been funded to search for natural mechanisms of warming... it has simply been assumed that global warming is manmade. Climate change - it happens, with or without our help"

This quote by Roy Spencer suggests that there has actually been an absence of research into natural systems of worldwide warming, and that it has actually been assumed that global warming is manmade. He is implying that climate change is a natural phenomenon that occurs despite human activity. This might be interpreted as a call for more research study into natural reasons for environment change, along with the impacts of human activity. It might also be seen as a reminder that climate modification is a natural process, and that humans need to not take all the blame for it. Ultimately, this quote is a reminder that climate change is a complex problem, which more research study is needed to understand its domino effects.
