The Main Cause Of Global Warming

Day in and day out it is difficult to avoid reading, hearing and even witnessing on the issue of global warming. Global warming is a gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants. The effects [of global warming] are being felt now with the currency of more extreme weather events and are predicted to intensify in coming decades. (Sadler-Smith 2014) Observations throughout the world make it clear that climate change is occurring, and particular scientific research seeks to demonstrate that the greenhouse gases released by human activities are the main cause to the issue.

One of the most direct evidence of

Extinction is expected to be the most detrimental effect of global warming. Scientists expected to see species extinction around 2020 because of global warming (Hoag 2012), but a large portions of polar bears have already gone extinct. As Earth’s climate zones shift, so will the species that populate them. A species, such as the polar bear, can only live in a narrow temperature range like the poles and mountaintops. Global warming has caused a less diverse biological planet. Along with polar bears, coral reefs are suffering from the effects of a climate change. The coral reefs collapse has striped fish of basic needs like food and shelter. The main cause of this destruction is warming oceans because of global warming. Coral reefs are very important to marine life, one third of the planets marine biodiversity would be affected if coral reef were wiped out. The US agency NOAA (the National Oceanic and Atmospheric Administration) puts the economic value to worth as much as 375$ billion each year (Sadler-Smith 2014). Since global warming effects so many ecosystems In negative ways, we must try to stop
