How can we get past the debates between natural and anthropogenic causes of global changes, and shift our attention towards reducing and dealing with the impacts of these changes?

How to minimize the natural vs anthropogenic controversy on global changes/warming issues? It seems that there is no more scientific doubts that climate changes are moving the earth system to a warmer period. It seems that the actual controversy on how much is natural and how much is human related is a worthless discussion in many senses. We have to focus on how to diminish the impacts rather than finding which is the guilty mechanism or process. Whatever the solutions, they have to be implemented in the human dimension first.

When we talk about the impact of human activities upon the earth system, we must be sure what is the background of the natural varibilities. We already know throughout the earth history, the earth system has been changing without human being. It is critical for us to know what is the extent of human factor over the natural factors before we talk about further issues.

How much biodiversity exists and how does its change or loss affect the system as a whole, and how modern methods of scientific investigations on biodiversity (including Artificial Intelligence) can help in solving this problem?

Biodiversity underpins the life-support system of our planet. But several factors, including natural and anthropogenic factors, have brought us to a critical point. The world is experiencing an unprecedented rate of species extinction, which may have far-reaching consequences for all life forms.

How much of the global climate change for the next 20-30 years as projected by the climate models with both natural and anthropogenic forcing? The projections of the global climate change as shown by the IPCC WG1 four reports are only considered the anthropogenic forcing scenarios. The predictions of the natural climate change that is very important are ignored.
