Answer: part 1
Global warming is causing a big impact that is affecting Earth as we speak. Its effects can cause sea levels to rise and will flood San Francisco and even Oakland. Global warming is the warming that happens when certain gases in the Earth's atmosphere trap heat. Global warming is caused mostly by humans that release these gases through factories, electricity production, and the burning of fossil fuels. Due to the fact that temperatures will rise, sea levels will rise too because the majority of the ice will melt. Yet, there is always a solution for every problem and in this case, humans can use renewable energy and recycle as much as possible to preserve our Earth.
There are several greenhouse gases that cause global warming. Human activity produces those gases in many different ways. According to National Geographic, “most of these greenhouse gases come from the burning of fossil fuels in cars, factories, and electricity production” (Cohen 3). In other words, most greenhouse gases are trapped in the atmosphere for a long time because humans release them, increasing global warming with rising temperatures. The burning of fossil fuels in cars, factories, and electricity production is a constant, continuous problem for the environment. “The gas responsible for most warming is carbon dioxide, also called CO2. Another gas that causes global warming include methane released from landfills and farming” (Cohen 3). In other words, carbon dioxide, or CO2, increases global warming due to the fact that it is released into the atmosphere from factories and electricity for example. Methane is worse than carbon dioxide though and it is released from the trash in landfills and from the cow’s
