Poster Title: We don’ t need more signs, we need more acts to save global warming. College: Universitas Brawijaya Background:
' Global warming ' is a phrase that refers to the effect on the climate of human activities, in particular the burning of fossil fuels( coal, oil and gas) and large-scale deforestation, which cause emissions to the atmosphere of large amounts of ' greenhouse gases ', of which the most important is carbon dioxide. Such gases absorb infrared radiation emitted by the Earth ' s surface and act as blankets over the surface keeping it warmer than it would otherwise be.
Human-caused global warming occurs when human activity introduces too much of certain types of gas into the atmosphere. More of this gas equals more warming. The atmospheric gases primarily responsible for the greenhouse effect are known as " greenhouse gases " and include water vapor, carbon dioxide( CO 2), methane( CH 4) and nitrous oxide( N 2O). The most prevalent greenhouse gas is CO 2.
There are too many signs but so little acts to prevent global warning. We can help to reduce the demand for fossil fuels, which in turn reduces global warming, by using energy more wisely. Such as reduce waste by choosing reuseable products instead of disposable ones, use less heat and air conditioner, buy energy-efficient products, and many more.
Goal:
If left unchecked, climate change will undo a lot of the progress made over the past years in development. It can also exacerbate, as we are already seeing, current threats such as food and water scarcity, which can lead to conflict.
The goal is to bring global warming under control by curtailing the release of carbon dioxide and other heat-trapping“ greenhouse” gases into the atmosphere. We can contribute to this global cause with personal actions. We can help immediately by becoming more energy efficient. Reducing our use of oil, gasoline and coal also sets an example for others to follow.
Doing nothing will end up costing us a lot more than if we take actions now that will lead to more jobs, greater prosperity, and better lives for all while reducing greenhouse gas emissions and building climate resilience.
