H2O vapor is the biggest greenhouse gas, though natural and non-harmful. The harmful ones are usually human caused, such as CO2, N2O, CH4 and many more.]]> 2017-12-19 02:12:54 UTC https://padlet.com/alvindurres/jrju0uep265f/wish/217131445 alvindurres https://padlet.com/alvindurres/jrju0uep265f/wish/217131718 It's a heating up of earth and its atmosphere due to greenhouse gases. Instead of keeping part of the infrared light and releasing the rest into space, more and more gas in the atmosphere simply keeps most of the infrared light inside the earth's atmosphere. This causes the environment to heat up, like a greenhouse.]]> 2017-12-19 02:16:47 UTC https://padlet.com/alvindurres/jrju0uep265f/wish/217131718 alvindurres https://padlet.com/alvindurres/jrju0uep265f/wish/217136821 https://scied.ucar.edu/carbon-dioxide-absorbs-and-re-emits-infrared-radiation
This website shows a great simulation of how a CO2 molecule absorbs and then re-emits infrared light. ]]> 2017-12-19 03:31:59 UTC https://padlet.com/alvindurres/jrju0uep265f/wish/217136821 alvindurres https://padlet.com/alvindurres/jrju0uep265f/wish/217136977 The one greenhouse gas which we cannot control (and unfortunately happens to be the one with the greatest impact) is H2O vapor. However, humans have had a great impact on the partial pressures of CO2 by burning fossil fuels, and CH4 by increasing livestock.]]> 2017-12-19 03:33:37 UTC https://padlet.com/alvindurres/jrju0uep265f/wish/217136977 alvindurres https://padlet.com/alvindurres/jrju0uep265f/wish/217137426 Engines running on fossil fuels
Burning of wood and deforestation
Human-raised cattle
Inefficient use of resources
Power plants running on fossil fuels/dangerous chemicals.
Overpopulation]]> 2017-12-19 03:41:56 UTC https://padlet.com/alvindurres/jrju0uep265f/wish/217137426 alvindurres https://padlet.com/alvindurres/jrju0uep265f/wish/221290695 These natural systems suck up and store carbon dioxide from the atmosphere. One example would be plants. They store carbon dioxide from the air during the day and use it for photosynthesis. When plants die and decompose, some of the carbon dioxide is also stored in the soil. Oceans are another example as carbon dioxide may dissolve in the water or be used by marine creatures. ]]> 2018-01-14 19:20:54 UTC https://padlet.com/alvindurres/jrju0uep265f/wish/221290695 alvindurres https://padlet.com/alvindurres/jrju0uep265f/wish/221291169 To alleviate the symptoms of this phenomena, we would need to contribute less by being more efficient in using resources and energy, not damaging forests and not having too many children.]]> 2018-01-14 19:25:29 UTC https://padlet.com/alvindurres/jrju0uep265f/wish/221291169 alvindurres https://padlet.com/alvindurres/jrju0uep265f/wish/221296158 The rise of the temperatures caused by global warming leads to many consequences, which can result in catastrophes. Such would be the melting of ice in the polar caps and thus the rise of sea levels. This results in the loss of land, disorientation of animals and their extinction as well as possible human deaths. The climate will also change further, possibly making the earth more hostile to life.]]> 2018-01-14 20:10:09 UTC https://padlet.com/alvindurres/jrju0uep265f/wish/221296158
