How are human activities contribute global warming. Answer please
Answers
On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
Answer:
The issue of attribution - showing definitely that human activities are causing global climate change to occur - is one of the most active areas of climate research. There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth's atmosphere, ocean and land surface to increase. That greenhouse gases do "trap"infrared heat is well established through laboratory experiments going back to the mid 1850s when Sir John Tyndall first measured the effect
