Erin finished talking about IPCC, They did seven smell tests to see if they could determine anything. The report consist of thousands of authors from dozen of countries and states in its summary. 52 scientists participated in this summary. In order to explain global warming you have to consider the cosmic rays, the pacific decadal oscillation. How the sun has decreasing magnetic field, sun spots, and contrails. Global warming is a extremely complex and important problem.Jessica talked about what we can do to prevent Global warming from getting any worse. You can do simple things such as: Not washing one item at a time, wait until you have a full load to wash it. Help by turning computers and other electronic devices off when not in use. Unplug them when you dont use them. Walk or ride a bike instead of driving. When its cold, instead of turning up heat, dress warmer. Plant trees they absorb carbon dioxide that pollutues the air. She also talked about thigns that the governments doing to help global warming. The government referencing to the Kyto Protocol. There are 183 countries that hace afreed to it at this point and a lot have made it a law. Our government issued a law called the Clean Air Act and one of the stipulations for that are companites have to change either the way the produce their products. The United States and China are the top two produces of greenhouse gases. Obama visted China, one of the topics that came up was climate change. We are both agreeing to work together to make more technology to advance technology and work on reducing carbon emissions that we produce.

Overpopulation is when one place is so dense that is causess deterioration and there are not enough resources for people. The main causes of it are: Decline in death rate, Increased birth rate, Migration, and Lack of Education. Less people are dying because we have more medicine that can cure more diseases. We are having more babies because medication has been created to help better with conception and better ferilization. Many people from other countries are migrating to other countries that dont have enough resources. Kids need to me educated of overpopulation. The effects of overpopulation are: Natural resources get usd up faster than they can ne replaced. There is a destroying of biological diversity. Lowering water levels by using more for electricity. Pulluting are, water, soil, and food chain. You destroy the stratospheric ozone layer that shields us from UV rays. Heat waves, devastating droughts. Solutions of overpopulation are: Education teach the general public about the seriousness of overpopulation is one of the ways to stop. An alternative solutions it to limit two babies per women.
