Global Warming

​Global temperatures have risen by 2% since 1850.

​Polar bears use the sea ice to help them search for food.

​Over the past 30 years, global average sea level has risen a total of 3.6 inches

​Coral bleaching is primarily caused by rising ocean temperatures due to climate change, but other factors like pollution, low tides, and excessive sunlight.

​In the last 100 years, atmospheric carbon dioxide (CO2) levels have increased significantly. Pre-industrial levels were around 280 parts per million (ppm), and today they are near 425 ppm, representing an approximate 50% increase.

Global warming increases evaporation rates, making places drier and more susceptible to drought. 

​Global warming can contribute to increased flood risk by intensifying precipitation events and raising sea levels

​Certain gases, like carbon dioxide and methane, absorb infrared radiation (heat) that the Earth emits after absorbing sunlight, preventing it from escaping into space.

​An increase in greenhouse gas concentrations, primarily due to human activities like burning fossil fuels, can lead to a heightened greenhouse effect, resulting in global warming and climate change.
