Rio de Janeiro - Deforestation has ceased to be the main cause of emissions of greenhouse gases in Brazil , which now has as its main source of emissions from burning fossil fuel , polluting " as a developed country ," according to investigator assessment Peruvian José Marengo , Latin American representative on the Intergovernmental Panel on Climate Change ( IPCC , acronym in English) . Professor He is a graduate of the National Institute for Space Research ( INPE ) and was nominated for the program by Brazil climate monitoring .
According to the researcher , the inventory of emissions of greenhouse gases , 2010 , launched in 2013 by the Ministry of Science , Technology and Innovation , shows that there was a reversal of the type of pollution prevalent in Brazil compared to the previous report , 2004 .
" Since 2008 , maybe a little earlier, the rate of deforestation in the Amazon has decreased considerably , but the fleet of vehicles increased . Agriculture also has improved somewhat , but still contributes mainly [ upland rice ] for the emission of methane , mining contributes , has plants. Which basically puts Brazil as polluter type first world is burning more fossil fuels , and here in Brazil are basically plants, any technology , and also the vehicle fleet . "
For him , despite the decrease in deforestation , the situation is still worrying . " Always criticize developed countries so [ burning fossil fuels ] . Obviously , if we had a system of mass transportation , reliable, comfortable , people leave the cars at home. But if you want to take the subway in Sao Paulo, Rio , at a certain time of day , is a humiliation . If you go by bike , run over you . So that has to change , the only way is to encourage public transport , decent for people to leave the car at home . "
Marengo remember that the IPCC does not work with geological time , studying the great cycles of the planet , and has proved that there were eras of warming and cooling of the Earth without human interference . The analyzes are of a period of 200 years and show that the natural causes of warming are long term and lead to small variations , while human intervention is short term and has action " superrápida " .
" The only way [ to prevent further warming ] is to reduce the emission of greenhouse gases , for example reducing the vehicle fleet , [ increase ] renewable energy , solar , wind , biomass , reduced consumption of thermoelectric obviously not we close , reset the contribution of gas burning fossil fuels , the ideal is to mix one and put other sources , obviously this can be costly . Mitigation measures are expensive . "
The most optimistic projections estimate that the planet's average temperature will rise about 1.5 degrees Celsius ( º C ) by 2100 . In the case of emissions of greenhouse gases , the increase can reach up to 4 ° C.
Marengo has today ( 8 ) a summary of the report of Working Group 1 of the IPCC , released in late September in Stockholm, Sweden , with the analysis of the physical and scientific systems and climate change . The Working Group 2 is the socio economic impacts of climate change and is expected to launch the report in March 2014 in Yokohama , Japan in Group 3 will present the results of studies and mitigation options for reducing the emission of greenhouse gases in April 2014 , in Berlin , Germany. Besides the three sectoral reports , is also expected to launch the synthesis report in October 2014 in Copenhagen, Denmark. This is the fifth report produced by the group , created by the United Nations .
