Introduction: why monitor carbon in Nunukan?
In the last two decades climate change has become a prominent issue for the global community. During the last century the meantemperature of the earth has increased by 0.6 ÂºC and the rate of change appears to increase. An increase of the atmosphericconcentration of the greenhouse gases(GHG), carbon dioxide (CO2), methane (CH4)and nitrous oxide (N2O) are identified as themain factor causing global warming. Duringthe last decade net CO2emission doubledfrom 1400 million Mg year-1to 2900 millionMg year-1. Meanwhile, the CO2concentrationin the atmosphere in 1998 was 360 ppmv, upfrom a value of 280 ppmv a century earlier,with a yearly increment of 1.5 ppmv(Houghton et al., 2001)
