Global warming is the one of the biggest problem faced by humanity. Global warming has been caused by natural and human activity (anthropogenic activity). There is relation among global warming, greenhouse effect, and climate change. The main cause of global warming is the greenhouse effect. The main effect of global warming is climate change.
- The global warming does indeed exist and it was mainly caused by human activity who is even still accelerating it.
- From global warming we expect a rise of the average temperature leading to among other things such as, melting of glaciers and melting of the polar ice, increase of the mean sea level as well as generally more of extreme weather events and nature disasters like droughts, floods, tornadoes, etc.
- Only a drastic reduction of the waste gas emissions in the very near future can stop this trend.
- CO2 (Carbon dioxide) emissions belong to the most important causes of global warming. CO2 is inevitably created by burning fossil fuels like e.g. oil, natural gas, diesel, organic-diesel, petrol, organic-petrol, ethanol.
- Recent investigations have shown that inconceivable catastrophic changes in the environment will take place as soon as the concentration of CO2 in the atmosphere reaches the level of about 450 ppm. Today's concentration is already at 380 ppm and it raises on average 2 - 3 ppm each year, so that the critical value will be reached in approximately 25 to 30 years from now. See here for some graphs.
