Current models vastly disagree on the fate on the current terrestrial carbon sink, leading to large uncertainties regarding climate-carbon cycle feedback? Recent research indicates that soils contain more than 4 times as much carbon as the atmosphere (>3000 Pg), and soil carbon processes are clearly understudied.

In the face of climate change, management actions are important tool for ecosystem conservation – we need to know if local and global efforts are effective or not – This is very crucial for the future of life in earth. It is only important to take action, it is more important to see the impact and whether we are doing the right thing and whether it is enough to safe lives and maintain ecosystem ability to cope with this global challenge or not?? .

How will the growing human population change the land cover (albedo), water and atmosphere composition in the next 20-50 years and what feedbacks will occur as symptoms of our planet resilience?

Feedbacks will create new conditions for our species that will have to evolve to adapt to polluted air, polluted water and a changed climate. The sooner we start paying attention to these feedbacks that will cause diseases, migrations, wars, famines, the sooner we can invest in creative strategies to improve or maintain human’s livelihoods and stop wasting time and energy on useless pursuits.

The interaction between natural and human systems is a two-way street; the impacts are jointly determined by what happens in both systems and the feedback loops that lead to adaptations and change. Understanding better how humans and environmental systems co-evolve–the likely direction and trends–is vital for allocating scarce resources to protect the earth.

To date many global change questions have focused on a component (e.g. the C cycle or sea level rise). The true outcomes of global change will be dictated by cumulative impacts, interactions and feedbacks. If they’re not addressed we may get some nasty non-linear surprises.
