global warming, Increase in the global average surface temperature resulting from enhancement of the greenhouse effect, primarily by air pollution.
Sea level rise is an increase in the level of the world's oceans due to the effects of global warming.Burning fossil fuels is one of the causes of global warming because it releases carbon dioxide and other heat-trapping gasses into the atmosphere.The oceans then absorb the majority of this heat. As water becomes warmer, it expands. This results in ocean levels rising worldwide.Ecosystems: Global warming stresses ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pest invasions, intense storm damage and salt invasion, just to name a few. Some of Australia's great natural icons, such as the Great Barrier Reef, are already threatened. Species: One in six species is at risk
Because of melting sea ice, it is likely that more polar bears will soon starve, warns a new study that discovered the large carnivores need to eat 60 percent more than anyone had realized. Turns
Climate change is directly contributing to humanitarian emergencies from heatwaves, wildfires, floods, tropical storms and hurricanes and they are increasing in scale, frequency and intensity.
