Global warming

A summary of an inconvenient truth video.

An Inconvenient Truth is a video about global warming in general; he talks about how Al Gore himself used to be the next president of the United State of America. His story, and what happened to his son and the effects that his son’s accident had on him; he was also in politics. Also it’s about the sun’s radiation and how the earth absorbs it.
He explained where the vast majority of the land mass is, which is in the northern hemisphere area and most of the vegetation is in the northern hemisphere. Also about 40% of people on earth get their drinking water from the melting ice of Himalayan glaciers. In addition what more can you learn from the northern hemisphere and CO2 concentrations in the past 1000 years. We can measure how much CO2 was trapped the year the snow fell and we can measure the temperature of that bubble. And they can count back the same as tree rings to measure the ice age.

An explanation of a global warming.

The sun’s radiation comes in a form of light waves which pass through the atmosphere, and then some of the radiation which is absorbed and warms the earth is radiated back to space in a form of infrared waves. And some of this outgoing infrared radiation is trapped by the earth’s atmosphere and warms it, and that’s a good thing because it keeps the temperature of the earth in a certain balance, keeps it relatively constant, and livable. But the problem is the thin layer of atmosphere is being thickened by all the global warming pollution. And what that means is that more of the outgoing infrared is trapped and so the atmosphere heats up and that’s global warming. The main and the most dangerous effects of global warming to earth is that many species are possibly facing extinction, like polar bears, penguins, and some kind of birds. And it has many effects on the near future like the water level will increase all over the world and lots of lands will sink.
