Many climatologists, researchers, and environmentalists are expressing concerns about changes in the Earth's overall climate. Extremely dangerous warming is believed to be occurring in the global global climate, a problem called "global warming." Global warming is the increase observed over a century in the average temperature of the Earth's climate system. is due to the harmful effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of life, but to do so we must act now if we continue to destroy the planet without regard. As for the severity of this problem, it could have several negative effects on us as humans and other living beings on Earth. This is why global warming is truly a global problem and must be tackled collectively. reduce dangerous levels of carbon dioxide emissions and we must work together. One of the main effects of global warming is sea level rise due to thermal expansion of the ocean, in addition to the melting of land ice. There are now dozens of land areas located well below sea level and the majority of these land areas are highly populated. At least 40 percent of the world's population lives within 62 miles of the ocean, putting millions of lives and billions of dollars' worth of property and infrastructure at risk. (Juliet Christian-Smith, 2011) This means that if sea levels rise to the projected level of 25 meters (82 feet), half of the planet will retreat toward the ocean. (Rohrer, 2007) Sea level rise also means higher tides and storm surges riding higher and higher seas, which is more dangerous to people and coastal information..... . middle of paper ......trying to do our part. But what is really needed is change on a national and global level. Only by convincing leaders to create laws that improve our energy policy and pushing companies to adopt sustainable business practices globally can we see real change. (EDF - Environmental Defense Fund, 2015) We need laws, policies and offenses…..etc. everything you need to control our CO2 emissions. There are many ways to improve the current state of global warming, such as limiting global warming pollution, using renewable energy, driving smarter vehicles, or even driving less. Even if the action is small, any change in our daily lives can be extremely useful, especially when it is carried out by a large number of people. We must remember that this is the only planet we have and that global warming is a global problem that must be taken seriously..
