Green house gasses release during the combustion of fossil fuels - true
Fossil fuels are: coal and petroleum. When they are combusted they produce around 21.3 billion tonnes of carbon dioxide (CO2) per year, but it is estimated that natural processes can only absorb about half of that amount, CO2 causes radiative forcing and thanks to CO2 the average surface temperature of the Earth rises. This phenomena of temperaturę rising causes hurricanes, tornadoes and tsunami and, of course, the level of the sees and oceans is also rising because glaciers are melting.
