9/7/2023 0 Comments What is the greenhouse effect![]() Hansen, a world-renowned expert on global warming and climate change in New York at NASA's Goddard Institute for Space Studies (GISS), "Climate is nearing dangerous tipping points. ![]() At that time, CO2 content in the atmosphere was 280 parts per million (ppm). This enhanced greenhouse effect began in the age of the Industrial Revolution of the 1700s. Concentration of other greenhouse gases, such as methane and nitrous oxides (also related to human activity) have increased 151 percent and 17 percent, respectively. The Earth's energy balance now must contend with what is referred to as the "enhanced greenhouse effect" or "anthropogenic greenhouse warming." CO2 is being added in voluminous amounts as a result of human activity deforestation agricultural practices the burning of fossil fuels for transportation urban development heating and cooling homes and industrial processes.ĬO2 in the atmosphere has increased 31 percent since 1895. CO2, one of the atmosphere's principal greenhouse gases, has been altered to such an extent by human activity that the natural greenhouse effect is no longer in balance. Since the Industrial Revolution (over the past 250 years or so), the natural greenhouse effect has been augmented by human interference. The Earth's natural greenhouse effect is critical for the survival and diversity of life. ![]() The entire Earth would have an ecosystem similar to that of the harshest areas in Antarctica. If this were the case, the Earth would look much different-there would most likely be very little, if any, liquid water available. Without this trapped warmth, the Earth would have an average temperature of -0.4☏ (-18☌). The natural amount keeps the Earth habitable. In this "greenhouse environment," it is the combination of water vapor and trace gases that are responsible for trapping the heat radiated from the Sun.
