Global warming is occurring as evidenced by rising average global temperatures over the past century according to thermometer records, with most of the warming occurring in recent decades due to human activity like burning fossil fuels and deforestation. This temperature increase is causing effects like melting ice sheets and glaciers, rising sea levels that threaten coastal and island communities, and increased risk of extinction for many plant and animal species. While a small minority of scientists disagree on the extent or cause of the warming, the vast majority agree that climate change poses risks and is human-caused.

1. Global warming, is it real or not?By: Sean Lavin & Shawna Schatz

2. How are temperatures increasing?The chemicals in cars, boats, factories, etc. are mixing with the greenhouse gases causing temperatures to increase.When humans cut down trees your taking away our oxygen. A easy way to see increasing temperatures is the thermometer records that were kept over the past century and a half. Earth’s average temperature has risen more than 1 degree Fahrenheit over the past century.Most scientists agree that the earth has warmed, but only by .0023 degrees.People produce 25% of CO2 and 6.6 tons or greenhouse gases.

3. How this temperature increase is affecting the world?The ice bergs in the North and South are melting away and polar bears are drowning.Temperatures are rising from the 6.6 tons of greenhouse gases that humans produce each year. Tropical islands could start to disappear because of rising sea levels.40 percent of the worlds species are being threatened.We are cutting down trees which means that we are loosing our oxygen.
