Now, to the important facts: There is only one species of cannabis. The Herald-Whig article correctly stated that cannabis sativa is the only species of cannabis. However, the article implies a botanical difference between marijuana and hemp. There is no difference.
Today, fossil fuel industries drill or mine for these energy sources, burn them to produce electricity, or refine them for use as fuel for heating or transportation. Over the past 20 years, nearly three-fourths of human-caused emissions came from the burning of fossil fuels. The Energy Department maintains emergency petroleum reserves, ensures responsible development of Americaâs oil and gas resources and executes natural gas regulatory responsibilities.
First, when fossil fuels (coal, oil, natural gas) are burned, the carbon in them combines with oxygen in the air to form CO2 (carbon dioxide). CO2 absorbs heat being radiated off the Earth that would normally escape into space, warming the atmosphere. Thus, burning fossil fuels cause global warming, resulting in climate change.
