Online Learning:
1. I learned that all of the events of the past decade, all of our memories have something in common. They all took place during the hottest decade ever recorded since humans begin keeping temperature records about 150 years ago.And I can say that the principle,"Everything is connected with everything else", is true.
In the last decade, the earth's temperature raised roughly a third of the degree Fahrenheit since 1880. It's risen about 1 1/2 degrees. You might say the Earth's having a fever and science has predicted that it's going to be much worse.
Majority of climate scientists say evidence are human-caused warming quicker but less understood is exactly how this warming could change the complex interactions between our planet's land, water, sky and the different organisms we have in our world.
Further complicating issue is that water vapor is actually the world's most abundant greenhouse gas, the same molecules that might cool the planet in cloud for actually warm even in the form of gas.
As the planet warms, more water evaporates from the ocean. Creating more of these heat-trapping greenhouse gas.
Carbon dioxide is the second most abundant greenhouse gas, and our biggest contribution to global warming. Fossil fuels burning releases large amounts of carbon dioxide into the air. NASA satellites capture the infra-red signature of carbon dioxide in the global atmosphere. NASA also monitors other greenhouse gases like methane, nitrous oxide, and CFCs.
Greenhouse gas is most likely the main contributor to current global warming. It's the key piece to the temperature puzzle, and it unlock the door in higher and higher temperatures.
2010. It marks the hottest decade ever recorded so far. What will the next 10 years become for our planet? Computer models predict even warmer temperature, extreme weather, less ice, and higher seas.
The severity of those changes will depend partly on how our planet's complex system responds and more importantly,ON WHAT CHOICES WE MAKE.
1. I watched a video about the Climate Change: A Global Scenario that is developed by NASA.
Online Collaboration:
1. I participated in the online discussion by watching more videos about climate change, making myself more aware of the present condition of our planet and sharing facts and my thoughts to social networking sites.
