B. P. dos  aRelationships between simultaneous methane, nitrous oxide and carbon dioxide fluxes and surface soil humidity and temperature in the Mata Atlântica Subtropical Forest, Brazil.h[electronic resource]  c2004  aMonitoring and other observations have shown that the chemical composition of the atmosphere is suffering modifications, and climate modelling predicts that the aver- age temperature of the planet's surface and lower atmosphere should increase by 1.5 to 4.5 DC by the middle of 21st century. Current opinion is that increases in atmospheric CO 2, CH 4 and N 2 0 concentrations, especially by human action, are the cause of this effect.  aFloresta Tropical  aTemperatura do Solo  aUmidade do Solo  aFluxo de gases  aGases de efeito estufa1 aNOGUEIRA, S.
