ESS3D Global Climate Change Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth's mean surface temperature (global warming) Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering
Greenhouse effect causes diagram global warming-The greenhouse effect has kept the Earth's average temperature a good deal higher for billions of years, making it possible for life as we know it to evolve Over the past several millennia the average Earth temperature has been about 15 °C (59 °F) The figure below illustrates how greenhouse gases keep the Earth warmer than it would beThe greenhouse effect has supported life on the earth for millions of years Today, however, the greenhouse effect is growing stronger as human activities such as deforestation and fossil fuel use release more and more greenhouse gases into the atmosphere This traps greater amounts of the sun's radiation, which contributes to rising temperatures, also known as global warming

What is an effect of Global Warming?And that's a topic for our next lesson Let's summarize our discussion of the greenhouse effect with a few key takeaways For one while there are clearly natural causes that contribute to global warming, none of these account for the increase of 12 degrees Celsius or 22 degrees Fahrenheit that we've observed so far
