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.
