RESUMO:

If the current scenario of anthropogenic emissions of greenhouse gases (GHGs) remains at the current pace, global warming can cause numerous climate changes, generating unimaginable human and environmental losses, the concern with the increase in global temperature is due to the its implications for diverse ecosystems and biomes, however, the implications for soil carbon stocks are uncertain. In view of the biogeochemical importance of these relationships, the present study proposes to evaluate possible changes in typical gas emissions CO₂ and CH₄ by heating the soil in an area of secondary tropical forest. For this purpose, the soil will be artificially heated to a temperature of 5 ° C above the ambient temperature at the time of collection. The study will be carried out at the UFOPA Experimental Unit, the area where the experiment will be installed has characteristics of secondary forest in regeneration for approximately 15 years. It is expected that the warming of the soil and its effects on the carbon cycle can accelerate the carbon decomposition process, thus having a greater release of CO₂ and CH₄ in the atmosphere. Studies that simulate the increase in soil temperature allow to quantify the real carbon emission from the forest soil and indicate how the natural dynamics of the carbon cycle behave under the effects of the increase in temperature caused by anthropic activities.
