Climate Change Fossil Fuels Must Stay Underground Scientists Say Full story. we know this warming is largely caused by human activities because the key role that carbon dioxide plays in maintaining earth’s natural greenhouse effect has been understood since the mid 1800s. unless it is offset by some equally large cooling influence, more atmospheric carbon dioxide will lead to warmer surface temperatures. Human activity is the cause of increased greenhouse gas concentrations. over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (co 2). this increase happens because the coal or oil burning process combines carbon with oxygen in the air to make co 2.
Global Greenhouse Gas Emissions Data Greenhouse Gas Ghg Emissions While earth’s climate has changed throughout its history, the current warming is happening at a rate not seen in the past 10,000 years.; according to the intergovernmental panel on climate change (), "since systematic scientific assessments began in the 1970s, the influence of human activity on the warming of the climate system has evolved from theory to established fact.". When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. greenhouse gases trap heat in our atmosphere, causing global warming. already the average global temperature has increased by 1c. warming above 1.5°c risks further sea level rise, extreme weather, biodiversity loss and species extinction. These observations have failed to show any long term changes that could fully account for the recent, rapid warming of earth’s temperature. finally, scientists know that carbon dioxide is a greenhouse gas and that it is released into the air when coal and other fossil fuels burn. The effects of the burning of fossil fuels, especially carbon dioxide, are having far reaching effects on our climate and ecosystems. the burning of fossil fuels is the primary cause of current climate change, altering the earth’s ecosystems and causing human and environmental health problems. flares burn at sunset in the bakken oil and gas.

What's the evidence for global warming and how do we know it's being caused by human activity? burning fossil fuels and chopping down trees lead to the release of this greenhouse gas. Scientists agree that global warming is caused mainly by human activity. specifically, the evidence shows that certain heat trapping gases, such as carbon dioxide, are warming the world—and that we release those gases when we burn fossil fuels like coal, oil, and gas. as scientific models and methods grow more sophisticated, and as we collect.
