When dinosaurs ruled the earth, the climate was most likely humid and warm. The carbon dioxide in the atmosphere was close to present day levels. Scientists found that the reasons of extinction of dinosaurs have linked to the global warming. Changes in climate would have occurred due to the disruption of wind and ocean currents. These marine changes, combined with volcanism and an extraterrestrial impact, may have caused the mass extinctions. (Dinosaurs Climate Change and Biodiversity) Similarly to the final stage of the Cretaceous, the average annual temperature rose by 1.5 F, with increases in some areas up to 4F in the last century. (Northwest Impacts & Adaptation). What makes the heat trap in our atmosphere?

The greenhouse effect is a major factor in keeping the Earth warm because it keeps some of the planet 's heat that would otherwise escape from the atmosphere out to space. In fact, without the greenhouse effect the Earth 's average global temperature would be much colder and life on Earth as we know it would not be possible. Nevertheless, human activities increases the level of greenhouse gases in the atmosphere. It has excess greenhouse gases tapping the heat on the earth. We should produce less greenhouse gases, but how do we measure the greenhouse gases emissions do we increase? We can calculate our ecological footprint. It measures the amount of biologically productive land and sea area supply the resources human population consumes. The average American…
